Issue #30768 reports that on native Windows PowerShell the destructive-slash
confirmation modal renders but never registers keypresses, leaving the user
unable to confirm or cancel /reset, /new, /clear, or /undo. The modal works
on macOS, Linux, and WSL; PR #23907 (merged May 11) replaced the
daemon-thread input() pattern with a prompt_toolkit-native keybinding modal
but the win32 input pipeline apparently doesn't dispatch keys to the
filter-conditioned handlers. The modal investigation is ongoing.
This change ships the immediate escape hatch: append `now`, `--yes`, or `-y`
to any destructive slash command to bypass the modal and run the action
immediately. Works on every platform without touching the broken Windows
code path.
/reset now -> reset, no modal
/new --yes my-session -> new session titled "my-session", no modal
/clear -y -> clear, no modal
/undo -y -> undo, no modal
The default behavior (modal prompts when approvals.destructive_slash_confirm
is True) is unchanged for users who don't pass a skip token.
Implementation:
- New classmethod HermesCLI._split_destructive_skip(text) -> (remainder, skip)
parses a destructive-slash command string, strips the leading "/cmd" word
and any recognized skip tokens (case-insensitive exact match, not substring),
and reports whether a skip was requested.
- HermesCLI._confirm_destructive_slash gains an optional cmd_original= arg.
When the arg contains a skip token, it returns "once" immediately —
before the gate check and before any modal rendering.
- The /clear, /new, /undo handlers in process_command pass cmd_original
through. /new additionally uses _split_destructive_skip to strip skip
tokens from the remaining text before deriving the session title, so
"/new now My Session" yields title="My Session" (not "now My Session").
Tests:
- 7 new unit tests in tests/cli/test_destructive_slash_confirm.py covering
the helper (recognized tokens, command-word stripping, case-insensitive
exact match, None/empty input) and the modal bypass (now and --yes both
skip; no-skip-token still consults the modal).
- 3 new integration tests in tests/cli/test_destructive_slash_inline_skip_e2e.py
driving HermesCLI.process_command end-to-end and asserting (a) new_session
is invoked, (b) the modal is never reached, (c) the skip token does not
leak into the session title, and (d) the no-skip-token path still reaches
the modal as a sanity check that we haven't accidentally short-circuited
the normal flow.
All 31 tests across the destructive-slash test surface pass.
Docs:
- website/docs/reference/slash-commands.md documents the new flags both in
the destructive-commands table and the dedicated approval section, with a
link back to issue #30768 explaining why the escape hatch exists.
The hardcoded constants in _display_resumed_history were exposed as
config in PR #4434; declare them in DEFAULT_CONFIG and the CLI fallback
dict so they show up in 'hermes config' diagnostics and the schema
validator.
PR #6a1aa420e coupled `display.tool_progress: verbose` (a per-tool display
toggle for full args / results / think blocks) to `self.verbose` — which
controls root-logger DEBUG level. Result: setting tool_progress: verbose
in config silently flipped every module in the process to DEBUG and
flooded the terminal with internal logging, far beyond just full tool
calls.
The two concepts are separate:
- `tool_progress_mode == 'verbose'` → display behavior (tool rendering)
- `self.verbose` → logging behavior (root logger → DEBUG, line 9795)
This change keeps PR #6a1aa420e's argparse.SUPPRESS / config-fallback
plumbing but severs the verbose-display → debug-logging link.
Changes:
- cli.py:2868 — `self.verbose` only follows explicit `verbose=` arg; no
longer auto-True when tool_progress_mode == 'verbose'.
- cli.py:_toggle_verbose — slash-cycle through tool progress modes no
longer flips `self.verbose` / `agent.verbose_logging` / `agent.quiet_mode`.
- cli.py:9355 — fix misleading label (drop 'and debug logs').
- tui_gateway/server.py:_make_agent — same decoupling on the TUI side
(verbose_logging no longer derived from tool_progress_mode).
- tests/cli/test_tool_progress_scrollback.py — invert the test that
asserted the broken coupling; add coverage for explicit `--verbose`
still enabling DEBUG independent of tool_progress.
Live verified:
- tool_progress: verbose, no --verbose flag → 0 DEBUG/INFO log lines
- --verbose flag explicit → 32 DEBUG/INFO log lines (as expected)
Improves the failure suffix on tool completion lines. Instead of always
showing '[error]' for non-terminal failures, parse the tool's JSON result
and surface the actual message:
Before: ┊ 📖 read foo.py 0.1s [error]
After: ┊ 📖 read foo.py 0.1s [File not found: foo.py]
Before: ┊ 💻 $ ls bad 0.1s [exit 127]
After: ┊ 💻 $ ls bad 0.1s [ls: cannot access 'bad'...]
Adds a _trim_error helper that strips long absolute paths down to the
filename and caps the suffix at 48 chars so it stays readable on narrow
terminals.
Threads the tool result through the tool.completed progress callback so
agent/display.get_cute_tool_message can inspect it. The cli.py [error]
post-suffix is removed in favor of the richer suffix _detect_tool_failure
now produces directly.
Originally proposed in PR #17194 by Albert.Zhou; salvaged onto current
main with the dead-code preview-length bumps dropped (tool_preview_length
config already strictly caps previews, so the per-tool n= defaults are
unreachable).

The interactive CLI input path consults decide_image_input_mode() to pick
between native image_url attachment and the vision_analyze text pipeline,
but the non-interactive 'hermes chat -Q -q ... --image FOO' path
unconditionally called _preprocess_images_with_vision() — so even with
`model.supports_vision: true` set, --image always went through the
text-pipeline. Symptom: vision_analyze runs 4-5s per image and the model
sees a lossy text summary instead of the actual pixels.
Mirror the interactive path: load config, call decide_image_input_mode,
branch on native vs text. Falls back to the text-pipeline on any import
or build error (Pyright-clean: _build_parts guarded with `is not None`).
Live E2E (provider=custom, base_url=openrouter, anthropic/claude-haiku-4.5,
red 64x64 PNG):
baseline (no override): vision_analyze called (8 log lines), 5.8s
with supports_vision: vision_analyze NOT called (0 log lines), 3.9s
Same model, same image, single knob flips text→native routing.
Add browser CDP launch candidates for Chrome, Chromium, Brave, and Edge while preserving Chrome-first selection. Retry candidate launch failures instead of giving up after the first executable.
Update /browser CLI and TUI messaging, docs, and tool descriptions from Chrome-only wording to Chromium-family browser support. Add regression coverage for Brave/Edge paths, Chrome-first precedence, fallback launches, and CDP endpoint probing.
`cli.py` was eager-importing `openai._base_client` at module-load time
purely to monkeypatch `AsyncHttpxClientWrapper.__del__` (defense against
"Press ENTER to continue..." errors when AsyncOpenAI clients are GC'd
against dead event loops). That import cost ~166ms / ~30MB on every
cold CLI start because openai's type tree (responses/*, graders/*) is huge.
Replace with a `sys.meta_path` finder that intercepts the first import
of `openai._base_client` from anywhere in the codebase, lets the normal
load run, then applies the `__del__ = lambda self: None` patch before
control returns to the caller. Same correctness guarantee (patch
applies before any AsyncOpenAI instance can be constructed), zero cost
until the SDK is actually needed.
Hot path: every hermes chat / gateway boot / cron tick / subagent spawn.
A/B benchmark, 10 runs each, fresh subprocess:
BEFORE AFTER delta
import cli wall 0.86s 0.62s -28% (median)
import cli wall 0.85s 0.59s -31% (min)
import cli RSS 91.2MB 74.0MB -19% (median)
The `neuter_async_httpx_del` function in agent/auxiliary_client.py is
unchanged; its tests still pass and any future callers can still invoke
it directly.
Verified:
- import cli no longer pulls openai into sys.modules
- first 'from openai._base_client import AsyncHttpxClientWrapper'
triggers the patch; __del__.__name__ == '<lambda>'
- tests/run_agent/test_async_httpx_del_neuter.py: 9/9 pass
- tests/agent/test_auxiliary_client.py: 159/159 pass
- tests/cli/: 715/715 pass
The SIGTERM/SIGHUP handler raised KeyboardInterrupt() at the end of its
agent-interrupt + grace-window sequence. Python delivers signals between
bytecodes on the main thread, so when the signal hit mid-event-loop
(typically inside prompt_toolkit's '_poll_output_size' coroutine's
'await asyncio.sleep()'), the KeyboardInterrupt unwound INTO that
coroutine. prompt_toolkit's Task captured it as a BaseException;
prompt_toolkit's '_handle_exception' then printed 'Unhandled exception
in event loop' + the full asyncio traceback and parked the terminal on
'Press ENTER to continue...' before exiting.
Same root cause as #13710, different surface: there the failure was an
EIO cascade after a logging-cache KeyError escaped the handler; here
it's the KBI raise itself landing inside an asyncio Task. The fix is
the same shape — let the event loop unwind on its own terms.
Now: schedule 'app.exit()' via 'loop.call_soon_threadsafe()'. The
prompt_toolkit Application returns normally from 'app.run()' and the
existing '(EOFError, KeyboardInterrupt, BrokenPipeError)' handler in
the input loop catches everything else. Fallback to 'raise
KeyboardInterrupt()' preserved for contexts where prompt_toolkit isn't
the active app (e.g. -q one-shot mode).
The agent interrupt + 1.5 s grace window run unchanged before the new
exit path, so subprocess-group cleanup ('os.killpg' on Linux) still
gets its window.
Tested live: external SIGTERM to the CLI (with 'kill <pid>') now exits
cleanly with no traceback dump and no ENTER pause.
Skill bundles are tiny YAML files in ~/.hermes/skill-bundles/ that
group several skills under one slash command. Invoking /<bundle-name>
from any surface (CLI, TUI, dashboard, any gateway platform) loads
every referenced skill into a single combined user message.
Use cases:
- /backend-dev → loads github-code-review + test-driven-development
+ github-pr-workflow as one bundle.
- /research → loads several research skills together.
- Team task profiles shared via dotfiles.
Behavior:
- Bundles take precedence over individual skills when slugs collide.
- Missing skills are skipped with a note, not fatal.
- No system-prompt mutation — bundles generate a fresh user message
at invocation time, the same way /<skill> does. Prompt cache stays
intact.
- Works in CLI dispatch, gateway dispatch, autocomplete (CLI + TUI),
/help display.
Schema (~/.hermes/skill-bundles/<slug>.yaml):
name: backend-dev
description: Backend feature work.
skills:
- github-code-review
- test-driven-development
instruction: |
Optional extra guidance prepended to the loaded skills.
New module: agent/skill_bundles.py — load, scan, resolve, build
invocation message, save, delete. yaml.safe_load only; broken
bundles log a warning and are skipped, never raise.
New CLI subcommand: hermes bundles {list,show,create,delete,reload}.
Implementation in hermes_cli/bundles.py; wired in hermes_cli/main.py.
'bundles' added to _BUILTIN_SUBCOMMANDS so plugin discovery skips it.
New in-session slash command: /bundles lists installed bundles in
both CLI and gateway. /<bundle-name> dispatch added to CLI (cli.py)
and gateway (gateway/run.py) before the existing /<skill-name> path.
Autocomplete: SlashCommandCompleter gained an optional
skill_bundles_provider parameter that defaults to None — the prompt
shows '▣ <description> (N skills)' for bundles vs '⚡' for skills.
Tests:
- tests/agent/test_skill_bundles.py — 33 tests covering slugify,
scan/cache freshness, resolve (including underscore→hyphen
Telegram alias), build_bundle_invocation_message (loading, missing
skills, user/bundle instruction injection, dedup), save/delete,
reload diff, list sort.
- tests/hermes_cli/test_bundles.py — 8 tests for the CLI
subcommand (create/list/show/delete/reload, --force, missing
bundle errors).
- tests/gateway/test_bundles_command.py — 4 tests for the gateway
handler and bundle resolution priority.
Live E2E: verified subprocess invocations of hermes bundles
{list,create,show,reload,delete} round-trip correctly against an
isolated HERMES_HOME.
Docs:
- website/docs/user-guide/features/skills.md — new 'Skill Bundles'
section with quick example, YAML schema, management commands,
behavior notes.
- website/docs/reference/cli-commands.md — 'hermes bundles' added to
the top-level command table and given its own subcommand section.
Salvages #23302 by @Bartok9. Four independent one-area fixes:
1. kanban boards delete alias now hard-deletes (not archives) — the
alias didn't carry --delete, so getattr(args, 'delete', False)
returned False. Detect boards_action=='delete' explicitly.
2. Gateway auto-title failures no longer leak as user-visible
warnings — debug-log only since they're not actionable.
3. Background process completion notification snaps truncation to
the next newline boundary, prepends a marker when content is
dropped.
4. _cprint() schedules the run_in_terminal coroutine via
asyncio.ensure_future so output isn't silently dropped from
background threads (fixes#23185 Bug A). Skips the
double-print fallback that would fire for mock paths.
Wraps _pt_print in try/except with a print() fallback. When a
kanban worker's stdout is piped to a log file, prompt_toolkit
raises NoConsoleScreenBufferError (Windows) or OSError (other)
because there is no real console buffer. The fallback keeps
worker output flowing instead of crashing.
* feat: add /update slash command to CLI and TUI
* test(cli): add Python tests for /update slash command
Co-authored-by: Cursor <cursoragent@cursor.com>
* fix(cli): address Copilot review for /update slash command
Route classic CLI /update through prompt_toolkit modal confirmation and
defer relaunch to the main-thread cleanup path after app.exit(). Tighten
Y/n semantics, add Python wrapper and catalog coverage tests, and assert
/update stays visible in the TUI command catalog.
Co-authored-by: Cursor <cursoragent@cursor.com>
* fix(cli): address review feedback on /update command
- Replace raw input() with _prompt_text_input_modal in _handle_update_command
to avoid EOF/hang/keystroke-leak races with prompt_toolkit's stdin ownership
- Fix confirmation logic: only proceed on recognized affirmative aliases
(y/yes/1/ok); cancel on everything else including empty string, typos,
and unrecognized input — matches all other [Y/n] prompts in the codebase
- Route relaunch through main-thread shutdown path: set _pending_relaunch
and return False from process_command so process_loop triggers app.exit();
run() then calls relaunch() after prompt_toolkit has restored terminal modes
and after cleanup — safe on both POSIX (execvp) and Windows (subprocess+exit)
- Fix misleading docstring in test_update_command.py: the Vitest only covers
the TypeScript slash handler that emits code 42, not the Python wrapper
branch that acts on it
- Rewrite tests to use SimpleNamespace pattern (like test_destructive_slash_confirm)
so _prompt_text_input_modal can be stubbed directly
- Add Python test for _launch_tui exit-code-42 → relaunch branch in main.py

When auxiliary compression's summary generation returns None (aux model
errored, returned non-JSON, timed out, etc.) the compressor previously
still dropped every middle message between compress_start..compress_end
and replaced them with a static 'Summary generation was unavailable'
placeholder. The session kept going but the user silently lost N turns
of context for nothing.
New behavior: on summary failure, compress() aborts entirely — returns
the input messages unchanged and sets _last_compress_aborted=True. The
existing _summary_failure_cooldown_until gate (30-60s) keeps the aux
model from being burned on every turn. Auto-compress callers detect
the no-op (len(after) == len(before)) and stop looping. The chat is
'frozen' at its current size until the next /compress or /new.
Manual /compress (CLI + gateway) now passes force=True which clears
the cooldown so users can retry immediately after an auto-abort. If
the manual retry also fails, the user gets a visible warning telling
them nothing was dropped and how to retry.
- agent/context_compressor.py: compress() gains force= kwarg; failure
branch sets _last_compress_aborted and returns messages unchanged
instead of inserting placeholder.
- run_agent.py: _compress_context() detects abort, surfaces warning,
skips session-rotation entirely, returns messages unchanged.
- cli.py + gateway/run.py: manual /compress paths pass force=True.
- gateway/run.py: hygiene + /compress handlers detect _last_compress_aborted
and emit the new 'Compression aborted' warning (gateway.compress.aborted)
instead of the old 'N historical messages were removed' message.
- locales/*.yaml: new gateway.compress.aborted key in all 16 locales.
- tests: updated to assert the abort contract (messages preserved,
compression_count not incremented, abort flag set, no placeholder
leaked). New test_force_true_bypasses_failure_cooldown covers the
manual-retry path.
The Tab-completion lambda captured _skill_commands at startup, so newly
installed skills were missing from Tab completion even after /reload-skills
reported them as added.
Two changes:
1. Tab-completion lambda now calls get_skill_commands() instead of reading
the module-level _skill_commands snapshot — ensures the lambda always
gets fresh data without needing to touch global state.
2. _reload_skills() now syncs cli.py's module-level _skill_commands via
get_skill_commands() after reload, so help display, command dispatch,
and any other direct _skill_commands readers also see the updated map.
Closes#26441
Six days after #23937 (608 fixes) the codebase had accumulated 241 new
PLR6201 violations. Same mechanical `x in (...)` → `x in {...}` fix,
same zero-risk profile: set lookup is O(1) vs O(n) for tuple and the
two are semantically equivalent for hashable scalar membership tests.
All 241 instances fixed via `ruff check --select PLR6201 --fix
--unsafe-fixes`, zero remaining. Every changed value is a hashable
scalar (str/int/None/enum/signal); no risk of unhashable runtime
errors. No behavior change.
Test plan:
- 119 files changed, +244/-244 (net zero) — exactly one-line edits
- `ruff check` clean afterward
- Compile checks pass on the largest touched files (cli.py, run_agent.py,
gateway/run.py, gateway/platforms/discord.py, model_tools.py)
- Subset broad test run on tests/gateway/ tests/hermes_cli/ tests/agent/
tests/tools/: 18187 passed, 59 pre-existing failures (verified against
origin/main with the same shape — identical failure count, identical
category — all xdist test-order flakes unrelated to this change)
Follows the same template as PR #23937 ([tracker: #23972](https://github.com/NousResearch/hermes-agent/issues/23972)).
Adds logger.info when large pastes are collapsed to file
references in both paste-code paths (handle_paste and
_on_text_changed). Logs paste ID, line count, character
count, and file path so operators can correlate missing-
content reports with specific paste files. This is a
diagnostic aid, not a fix for the paste-drop issue.
Adds a pure-local recap of recent session activity — turn counts,
tools used, files touched, last user ask, last assistant reply —
appended to the existing /status output. Useful when juggling multiple
sessions and you want a one-glance reminder of where this one left off.
Inspired by Claude Code 2.1.114's /recap, but folded into /status so
we don't add a 6th info command. Pure local computation: no LLM call,
no auxiliary model, no prompt-cache invalidation, instant and free.
Salvage of #18587 — kept the shared hermes_cli.session_recap.build_recap
helper and its 13 unit tests, dropped the /recap slash command +
ACTIVE_SESSION_BYPASS_COMMANDS entry + Level-2 bypass since /status
already covers both surfaces.
Tailored to hermes-agent's tool vocabulary: file-editing tools
(patch, write_file, read_file, skill_manage, skill_view) surface
touched paths; tool-call counts highlight which classes of work
drove the session.

Surface live background-task count in the prompt_toolkit status bar so users
can see at a glance that a /background task exists and is running — no need
to ask the agent about it (the agent has no visibility into bg sessions by
design).
- _get_status_bar_snapshot now reports active_background_tasks from len()
of the live _background_tasks dict (entries are removed in the task
thread's finally block, so this reflects truly-running tasks)
- Indicator shown only on medium (<76) and wide (>=76) tiers; narrow (<52)
stays minimal since it's already cramped
- No invalidate plumbing needed: status bar fragments are pulled via lambda
on every redraw, and the bg thread already calls _app.invalidate() on exit
Refs #8568
Port from google-gemini/gemini-cli#19332.
Users can now exit with '/exit --delete' (or '/quit --delete', '/exit -d')
to permanently remove the current session's SQLite history plus on-disk
transcripts (*.json / *.jsonl / request_dump_*) in one shot. Useful for
privacy-sensitive workflows and one-off interactions where leaving a
session recording behind is undesirable.
Implementation:
- New HermesCLI._delete_session_on_exit one-shot flag (defaults False).
- process_command() parses --delete / -d after /exit or /quit and arms
the flag. Unknown args print a hint and keep the CLI running (prevents
typos like '/exit -delete' from accidentally exiting).
- Shutdown path calls SessionDB.delete_session(session_id, sessions_dir=...)
right after end_session() when the flag is set. That API already
existed for 'hermes sessions delete' and handles both SQLite removal
(orphaning child sessions so FK constraints hold) and on-disk file
cleanup.
- /quit CommandDef now advertises '[--delete]' in args_hint so /help
and CLI autocomplete surface it.
Tests: tests/cli/test_exit_delete_session.py (12 cases covering both
aliases, case insensitivity, whitespace, short form, unknown-arg
rejection, and registry metadata).
E2E-verified with isolated HERMES_HOME: session row deleted, all three
transcript/request-dump files removed, second delete_session call
correctly returns False.
Tirith ships no Windows binary, so on every Windows CLI startup users
saw a scary 'tirith security scanner enabled but not available' banner
they could not act on. The banner suggested degraded security; in
reality pattern-matching guards still run and the message was pure noise.
Fix:
- New public is_platform_supported() helper in tools/tirith_security.py
that returns False when _detect_target() doesn't resolve (Windows, any
non-x86_64/aarch64 arch).
- ensure_installed(), _resolve_tirith_path(), and check_command_security()
short-circuit on unsupported platforms: cache _resolved_path =
_INSTALL_FAILED with reason 'unsupported_platform', skip PATH probes,
skip the background download thread, skip the disk failure marker, and
return allow with an empty summary from check_command_security so the
spawn loop never fires.
- Explicit user-configured tirith_path is still honored everywhere (a
user who built tirith themselves under WSL keeps that path).
- CLI banner in cli.py gated on is_platform_supported() — fires only on
platforms where tirith *should* work but isn't installed.
- Docs note tirith's supported-platform list and point Windows users at
WSL.
Tests: tests/tools/test_tirith_security.py +8 tests covering Linux
x86_64, Darwin arm64, Windows, and unknown-arch verdicts plus the
silent ensure_installed / check_command_security / _resolve_tirith_path
fast-paths and the explicit-path override.
test_tirith_security.py 75 passed (8 new + 67 pre-existing)
test_command_guards.py 19 passed
When running with --yolo, all dangerous command approvals are bypassed.
Make this state visible so users don't forget:
- Banner: '⚠ YOLO mode — all approval prompts bypassed' line in red, only
shown when YOLO is active. Default case is silent (no extra line, no
always-on 'restricted' label).
- Status bar: '⚠ YOLO' fragment appended in red (#FF4444 bold) across all
three width tiers (<52, <76, ≥76) in both the plain-text fallback and
the fragments builder.

#25975 (salvaging #24403) clamped decorative scrollback Panels and
streaming box rules to `max(32, min(width, 56))` as a defense against
terminal-emulator reflow when columns shrink. On any modern wide
terminal this made the response/reasoning borders look stubby — 56
cols inside a 200-col viewport.
#26137 (salvaging #25981, by @OutThisLife) landed a more fundamental
fix: prompt_toolkit's `_output_screen_diff` is monkey-patched so its
reserve-vertical-space cursor move no longer pushes chrome into
scrollback at all. With that in place, the clamp is no longer
load-bearing for the chrome-into-scrollback class of bugs — the
remaining risk is purely cosmetic reflow of *already stamped*
Panel borders during an aggressive column shrink, which we now
accept as a tradeoff for restoring proper full-width rendering.
Changes:
- `_scrollback_box_width()` returns `max(32, width)` (just the floor,
no upper cap). All 10 call sites stay valid.
- Updated `test_scrollback_box_width_caps_to_resize_safe_value` to
the new `test_scrollback_box_width_returns_viewport_width` asserting
full-width passthrough above the 32-col floor.
Floor of 32 is kept so `'─' * (w - 2)` math stays positive on tiny
terminals.
Refs #18449#19280#22976 (the original reflow class) and #25975
(the clamp this reverts).
Two long-standing prompt_toolkit bugs in the base hermes CLI:
1. Resize duplication. Column-shrink resize used to push 40+ rows of
duplicate chrome (status bar, input rules) into terminal scrollback
every resize. Same wall as pt issues #29 (open since 2014), #1675,
#1933 — aider/xonsh/ipython all use alt-screen to dodge it.
Root cause (verified by reading prompt_toolkit/renderer.py):
_output_screen_diff (renderer.py L232-242) deliberately moves the
cursor to the bottom of the canvas after every paint 'to make sure
the terminal scrolls up'. In non-fullscreen mode this scrolls chrome
content into terminal scrollback on every render — not just on
resize.
Fix: monkey-patch prompt_toolkit.renderer._output_screen_diff to
bypass the reserve-vertical-space cursor move. When pt's logic checks
'if current_height > previous_screen.height', we inflate the previous
screen height so the branch falls through. ~30-line wrapper, no fork
of pt, no alt-screen, no DECSTBM scroll region.
Verified empirically in real Terminal.app: 10 resizes (mixed
shrinks/widens 1300→500→1400) during streaming produced ZERO
scrollback delta, full agent response preserved, status bar pinned
at bottom, no visible duplicates. pt is pinned to ==3.0.52 so the
private-function patch is safe; future pt bumps will need to
re-verify the signature matches.
2. Light-mode terminal visibility. Hardcoded skin colors (#FFF8DC
cornsilk, #FFD700 gold, #B8860B dark goldenrod) are tuned for dark
Terminal.app — invisible on light/cream backgrounds.
Port ui-tui/src/theme.ts detectLightMode() to Python so the base CLI
adapts. Detection priority: HERMES_LIGHT/HERMES_TUI_LIGHT env →
HERMES_TUI_THEME=light|dark → HERMES_TUI_BACKGROUND=#RRGGBB →
COLORFGBG env (xterm/Konsole/urxvt) → OSC 11 query
(\x1b]11;?\x1b\\) with 100ms timeout → default dark. OSC 11 is
tty-gated so gateway/cron/batch/subagent code paths don't pay the
timeout cost.
When light mode is detected, dark-mode colors auto-remap to readable
equivalents (#FFF8DC → #1A1A1A, #FFD700 → #9A6B00, etc). Hooked at
three points:
- _hex_to_ansi() — auto-remaps any color emitted via the ANSI helper
- _build_tui_style_dict() — rewrites pt style strings (chrome bg/fg)
- SkinConfig.get_color() — wrapped at module load so Rich Panel
borders/body text get the remap too
Status-bar foreground colors (#C0C0C0, #888888, etc.) are explicitly
skipped because they're paired with a dark navy bg — remapping them
would make them invisible in dark mode.
3. Other visibility fixes: [thinking] reasoning preview now uses ANSI
dim+italic (\x1b[2;3m) instead of #B8860B so it inherits terminal
default fg color. Input/prompt area defaults to terminal default fg
(was #FFF8DC cornsilk → invisible on cream).

On macOS with uv-managed cPython 3.11, the default kqueue selector cannot
register fd 0, so prompt_toolkit's loop.add_reader raises
OSError(EINVAL) ("[Errno 22] Invalid argument") from kqueue.control()
and the agent crashes immediately on startup (#5884, also reported in
#6393).
Probe KqueueSelector.register(0, EVENT_READ) before launching
prompt_toolkit. If it fails, install an event-loop policy that returns a
SelectorEventLoop backed by SelectSelector — select() works fine on
stdin in this Python build, so add_reader succeeds and the agent
launches normally.
Also extend the existing #6393 fallback handler to recognize EINVAL /
EBADF / "Invalid argument" so that any future selector failure on stdin
shows the friendly "reinstall Python via pyenv or Homebrew" guidance
instead of an opaque traceback.
Verified on macOS (Darwin 24.6.0) with uv-managed cPython 3.11.15: the
kqueue probe fails, the policy switch fires, and `hermes` launches
cleanly. No effect on platforms where kqueue can register fd 0.
The 'sessions' command has been registered in the central command
registry since #20805 (May 2025) and surfaces in /help and tab-completion,
but the classic CLI's process_command() never had an elif branch for it.
The canonical name fell through and printed 'Unknown command: sessions'.
The TUI side was wired up correctly via the SessionPicker overlay; only
the legacy CLI was missing the dispatch.
Adds _handle_sessions_command() which mirrors /resume's no-arg behavior
inline (the CLI has no overlay primitive equivalent to the TUI picker):
- /sessions and /sessions list → print the recent-sessions table
- /sessions <id_or_title> → delegates to _handle_resume_command
Includes regression tests covering the dispatcher wiring (the original
bug) plus the three handler branches.
When the terminal shrinks, already-printed box-drawing rules (response,
reasoning, streaming TTS, background-task Panels) reflow into multiple
narrower rows — visible as duplicated horizontal separators / ghost
lines in scrollback. Similarly, prompt_toolkit redraws a fresh status
bar on SIGWINCH on top of one the terminal just reflowed, producing
double-bar artifacts on column shrink.
Two surgical changes:
1. Decorative scrollback boxes now use a new
`HermesCLI._scrollback_box_width()` helper that clamps to
`max(32, min(width, 56))`. The live TUI footer is unaffected and still
uses the full width. Covers: streaming response box (open + close),
reasoning box (open + close, both streaming and post-stream paths),
streaming-TTS box close, final-response Rich Panel, and the
background-task Rich Panel.
2. `_recover_after_resize()` now also sets a new
`_status_bar_suppressed_after_resize` flag so the dynamic status bar
and both input separator rules stay hidden until the next user input.
The flag is cleared in the process loop the moment the user submits
their next prompt, restoring chrome cleanly.
Tests:
- New `test_input_rules_hide_after_resize_until_next_input` covers the
flag's effect on rule heights.
- New `test_scrollback_box_width_caps_to_resize_safe_value` covers the
helper at floor / cap / mid-range / overflow.
- Existing resize-recovery test extended to assert the flag flips.

The spinner already shows tool activity visually; the 1.2 kHz tone on
every tool.started event was unwanted noise (especially on WSL2, where
each beep also triggers Windows Terminal's bell notification).
Removed the play_beep call in _on_tool_progress entirely. Record
start/stop beeps (gated by voice.beep_enabled) are unaffected.
The _approval_callback method in HermesCLI hardcoded timeout=60
instead of reading the approvals.timeout config value. This meant
the config setting was silently ignored for CLI interactive prompts.
Other approval paths (callbacks.py, tools/approval.py) already read
the config correctly — only cli.py was missed.
* feat(goals): /subgoal — user-added criteria appended to active /goal
Layers a /subgoal command on top of the existing freeform Ralph judge
loop. The user can append extra criteria mid-loop; the judge factors
them into its done/continue verdict and the continuation prompt
surfaces them to the agent. No new tool, no agent self-judging — the
existing judge model just sees a richer prompt.
Forms:
/subgoal show current subgoals
/subgoal <text> append a criterion
/subgoal remove <n> drop subgoal n (1-based)
/subgoal clear wipe all subgoals
How it integrates:
- GoalState gains `subgoals: List[str]` (default []), backwards-compat
for existing state_meta rows.
- judge_goal accepts an optional subgoals kwarg; non-empty switches to
JUDGE_USER_PROMPT_WITH_SUBGOALS_TEMPLATE which lists them as
numbered criteria and asks 'is the goal AND every additional
criterion satisfied?'
- next_continuation_prompt picks CONTINUATION_PROMPT_WITH_SUBGOALS_TEMPLATE
when non-empty so the agent sees what to target.
- /subgoal is allowed mid-run on the gateway since it only touches the
state the judge reads at turn boundary — no race with the running
turn.
- Status line shows '... , N subgoals' when present.
Surface:
- hermes_cli/goals.py — field, prompt blocks, manager methods, judge weave
- hermes_cli/commands.py — /subgoal CommandDef
- cli.py — _handle_subgoal_command
- gateway/run.py — _handle_subgoal_command + mid-run dispatch
- tests/hermes_cli/test_goals.py — 15 new tests (backcompat, mutation,
persistence, prompt template selection, judge-prompt content via mock,
status-line rendering)
77 goal-related tests passing across goals + cli + gateway + tui.
* fix(goals): slash commands don't preempt the goal-continuation hook
Two findings from live-testing /subgoal:
1. Slash commands queued while the agent is running landed in
_pending_input (same queue as real user messages). The goal hook's
'is a real user message pending?' check returned True and silently
skipped — but the slash command consumes its queue slot via
process_command() which never re-fires the goal hook, so the loop
stalls indefinitely. Now the hook peeks the queue and only defers
when a non-slash payload is present.
2. The with-subgoals judge prompt was too soft — opus 4.7 said 'done,
implying all requirements met' without verifying. Tightened to
demand specific per-criterion evidence (file contents, output line,
command result) and explicitly reject phrases like 'implying it was
done.'
Live verified: /subgoal injected mid-loop now correctly forces the
judge to refuse done until the new criterion is met. Agent gets the
continuation prompt with subgoals listed, updates the script, judge
confirms done with specific evidence cited.
The interactive CLI /model picker was the third call-site duplicating
the inline config-slice + list_authenticated_providers pattern that
PR #23666 consolidated for the dashboard and TUI. Route it through
load_picker_context() + build_models_payload() too so all surfaces
that show authenticated providers share one substrate.
Side effect: cli.py now also benefits from the latent v12+ keyed
providers fix (custom_providers populated via
get_compatible_custom_providers, not cfg.get raw).
The aux-task switcher (hermes_cli/main.py) and gateway model
switcher (gateway/run.py) deliberately stay on the legacy path —
they use different config sections (auxiliary.<task>.*) and a
different config loader (_load_gateway_config) respectively, so
forcing them through ConfigContext would either overload its
semantics or grow the module past the clean refactor scope.
* feat(codex-runtime): scaffold optional codex app-server runtime
Foundational commit for an opt-in alternate runtime that hands OpenAI/Codex
turns to a 'codex app-server' subprocess instead of Hermes' tool dispatch.
Default behavior is unchanged.
Lands in three pieces:
1. agent/transports/codex_app_server.py — JSON-RPC 2.0 over stdio speaker
for codex's app-server protocol (codex-rs/app-server). Spawn, init
handshake, request/response, notification queue, server-initiated
request queue (for approval round-trips), interrupt-friendly blocking
reads. Tested against real codex 0.130.0 binary end-to-end during
development.
2. hermes_cli/runtime_provider.py:
- Adds 'codex_app_server' to _VALID_API_MODES.
- Adds _maybe_apply_codex_app_server_runtime() helper, called at the
end of _resolve_runtime_from_pool_entry(). Inert unless
'model.openai_runtime: codex_app_server' is set in config.yaml AND
provider in {openai, openai-codex}. Other providers cannot be
rerouted (anthropic, openrouter, etc. preserved).
3. tests/agent/transports/test_codex_app_server_runtime.py — 24 tests
covering api_mode registration, the rewriter helper (default-off,
case-insensitive, opt-in, non-eligible providers preserved), version
parser, missing-binary handling, error class. Does NOT require codex
CLI installed.
This commit is wire-only: the api_mode is recognized but AIAgent does
not yet branch on it. Followup commits add the session adapter, event
projector, approval bridge, transcript projection (so memory/skill
review still works), plugin migration, and slash command.
Existing tests remain green:
- tests/cli/test_cli_provider_resolution.py (29 passed)
- tests/agent/test_credential_pool_routing.py (included above)
* feat(codex-runtime): add codex item projector for memory/skill review
The translator that lets Hermes' self-improvement loop keep working under the
Codex runtime: converts codex 'item/*' notifications into Hermes' standard
{role, content, tool_calls, tool_call_id} message shape that
agent/curator.py already knows how to read.
Item taxonomy (matches codex-rs/app-server-protocol/src/protocol/v2/item.rs):
- userMessage → {role: user, content}
- agentMessage → {role: assistant, content: text}
- reasoning → stashed in next assistant's 'reasoning' field
- commandExecution → assistant tool_call(name='exec_command') + tool result
- fileChange → assistant tool_call(name='apply_patch') + tool result
- mcpToolCall → assistant tool_call(name='mcp.<server>.<tool>') + tool result
- dynamicToolCall → assistant tool_call(name=<tool>) + tool result
- plan/hookPrompt/etc → opaque assistant note, no fabricated tool_calls
Invariants preserved:
- Message role alternation never violated: each tool item produces at most
one assistant + one tool message in that order, correlated by call_id.
- Streaming deltas (item/<type>/outputDelta, item/agentMessage/delta)
don't materialize messages — only item/completed does. Mirrors how
Hermes already only writes the assistant message after streaming ends.
- Tool call ids are deterministic (codex item id-based) so replays produce
identical messages and prefix caches stay valid (AGENTS.md pitfall #16).
- JSON args use sorted_keys for the same reason.
Real wire formats verified against codex 0.130.0 by capturing live
notifications from thread/shellCommand and including one as a fixture
(COMMAND_EXEC_COMPLETED).
23 new tests, all green:
- Streaming deltas don't materialize (3 paths)
- Turn/thread frame events are silent
- commandExecution: 5 tests including non-zero exit annotation +
deterministic id stability across replays
- agentMessage + reasoning attachment + reasoning consumption
- fileChange: summary without inlined content
- mcpToolCall: namespaced naming + error surfacing
- userMessage: text fragments only (drops images/etc)
- opaque items: no fabricated tool_calls
- Helpers: deterministic id stability + sorted JSON args
- Role alternation invariant across all four tool-shaped item types
This commit is a pure addition. AIAgent integration (the wire that uses the
projector) is the next commit.
* feat(codex-runtime): add session adapter + approval bridge
The third self-contained module: CodexAppServerSession owns one Codex
thread per Hermes session, drives turn/start, consumes streaming
notifications via CodexEventProjector, handles server-initiated approval
requests, and translates cancellation into turn/interrupt.
The adapter has a single public per-turn method:
result = session.run_turn(user_input='...', turn_timeout=600)
# result.final_text → assistant text for the caller
# result.projected_messages → list ready to splice into AIAgent.messages
# result.tool_iterations → tick count for _iters_since_skill nudge
# result.interrupted → True on Ctrl+C / deadline / interrupt
# result.error → error string when the turn cannot complete
# result.turn_id, thread_id → for sessions DB / resume
Behavior:
- ensure_started() spawns codex, does the initialize handshake, and
issues thread/start with cwd + permissions profile. Idempotent.
- run_turn() blocks until turn/completed, drains server-initiated
requests (approvals) before reading notifications so codex never
deadlocks waiting for us, projects every item/completed via the
projector, and increments tool_iterations for the skill nudge gate.
- request_interrupt() is thread-safe (threading.Event); the next loop
iteration issues turn/interrupt and unwinds.
- turn_timeout deadlock guard issues turn/interrupt and records an
error if the turn never completes.
- close() escalates terminate → kill via the underlying client.
Approval bridge:
Codex emits server-initiated requests for execCommandApproval and
applyPatchApproval. The adapter translates Hermes' approval choice
vocabulary onto codex's decision vocabulary:
Hermes 'once' → codex 'approved'
Hermes 'session' or 'always' → codex 'approvedForSession'
Hermes 'deny' / anything else → codex 'denied'
Routing precedence:
1. _ServerRequestRouting.auto_approve_* flags (cron / non-interactive)
2. approval_callback wired by the CLI (defers to
tools.approval.prompt_dangerous_approval())
3. Fail-closed denial when neither is wired
Unknown server-request methods are answered with JSON-RPC error -32601
so codex doesn't hang waiting for us.
Permission profile mapping mirrors AGENTS.md:
Hermes 'auto' → codex 'workspace-write'
Hermes 'approval-required' → codex 'read-only-with-approval'
Hermes 'unrestricted/yolo' → codex 'full-access'
20 new tests, all green. Combined with prior commits this PR now has
67 tests across three modules:
- test_codex_app_server_runtime.py: 24 (api_mode + transport surface)
- test_codex_event_projector.py: 23 (item taxonomy projections)
- test_codex_app_server_session.py: 20 (turn loop + approvals + interrupts)
Full tests/agent/transports/ directory: 249/249 pass — no regressions
to existing transport tests.
Still no wire into AIAgent.run_conversation(); that integration commit
is small and goes next.
* feat(codex-runtime): wire codex_app_server runtime into AIAgent
The integration commit. AIAgent.run_conversation() now early-returns to a
new helper _run_codex_app_server_turn() when self.api_mode ==
'codex_app_server', bypassing the chat_completions tool loop entirely.
Three small surgical edits to run_agent.py (~105 LOC total):
1. Line ~1204 (constructor api_mode validation set):
Add 'codex_app_server' so an explicit api_mode='codex_app_server'
passed to AIAgent() isn't silently rewritten to 'chat_completions'.
2. Line ~12048 (run_conversation, just before the while loop):
Early-return to _run_codex_app_server_turn() when self.api_mode is
'codex_app_server'. Placed AFTER all standard pre-loop setup —
logging context, session DB, surrogate sanitization, _user_turn_count
and _turns_since_memory increments, _ext_prefetch_cache, memory
manager on_turn_start — so behavior outside the model-call loop is
identical between paths. Default Hermes flow is unchanged when the
flag is off.
3. End-of-class (line ~15497):
New method _run_codex_app_server_turn(). Lazy-instantiates one
CodexAppServerSession per AIAgent (reused across turns), runs the
turn, splices projected_messages into messages, increments
_iters_since_skill by tool_iterations (since the chat_completions
loop normally does that per iteration), fires
_spawn_background_review on the same cadence as the default path.
Counter accounting:
_turns_since_memory ← already incremented at run_conversation:11817
(gated on memory store configured) — codex
helper does NOT touch it (would double-count).
_user_turn_count ← already incremented at run_conversation:11793
— codex helper does NOT touch it.
_iters_since_skill ← incremented in the chat_completions loop per
tool iteration. Codex helper increments by
turn.tool_iterations since the loop is bypassed.
User message:
ALREADY appended to messages by run_conversation pre-loop (line 11823)
before the early-return reaches us. Helper does NOT append again.
Regression test test_user_message_not_duplicated guards this.
Approval callback wiring:
Lazy-fetches tools.terminal_tool._get_approval_callback at session
spawn time, passes to CodexAppServerSession. CLI threads with
prompt_toolkit get interactive approvals; gateway/cron contexts get
the codex-side fail-closed deny.
Error path:
Codex session exceptions become a 'partial' result with completed=False
and a final_response that explicitly tells the user how to switch back:
'Codex app-server turn failed: ... Fall back to default runtime with
/codex-runtime auto.' Same return-dict shape as the chat_completions
path so all callers (gateway, CLI, batch_runner, ACP) work unchanged.
9 new integration tests in tests/run_agent/test_codex_app_server_integration.py:
- api_mode='codex_app_server' is accepted on AIAgent construction
- run_conversation returns the expected codex shape
(final_response, codex_thread_id, codex_turn_id, completed, partial)
- Projected messages are spliced into messages list
- _iters_since_skill ticks per tool iteration
- _user_turn_count delegated to standard flow (not double-counted)
- User message appears exactly once (regression guard)
- _spawn_background_review IS invoked (memory/skill review keeps working)
- chat.completions.create is NEVER called (loop fully bypassed)
- Session exception → partial result with /codex-runtime auto hint
- Interrupted turn → partial result with error preserved
Adjacent test runs confirm no regressions:
- tests/run_agent/test_memory_nudge_counter_hydration.py: green
- tests/run_agent/test_background_review.py: green
- tests/run_agent/test_fallback_model.py: green
- tests/agent/transports/: 249/249 green
Still missing for full feature: /codex-runtime slash command, plugin
migration helper, docs page, live e2e test gated on codex binary. Those
are the remaining followup commits.
* feat(codex-runtime): add /codex-runtime slash command (CLI + gateway)
User-facing toggle for the optional codex app-server runtime. Follows the
'Adding a Slash Command (All Platforms)' pattern from AGENTS.md exactly:
single CommandDef in the central registry → CLI handler → gateway handler
→ running-agent guard → all surfaces (autocomplete, /help, Telegram menu,
Slack subcommands) update automatically.
Surface:
/codex-runtime — show current state + codex CLI status
/codex-runtime auto — Hermes default runtime
/codex-runtime codex_app_server — codex subprocess runtime
/codex-runtime on / off — synonyms
Files changed:
hermes_cli/codex_runtime_switch.py (new):
Pure-Python state machine shared by CLI and gateway. Parse args,
read/write model.openai_runtime in the config dict, gate enabling
behind a codex --version check (don't let users opt in to a runtime
they have no binary for; print npm install hint instead).
Returns a CodexRuntimeStatus dataclass that callers render however
suits their surface.
hermes_cli/commands.py:
Single CommandDef entry, no aliases (codex-runtime is its own thing).
cli.py:
Dispatch in process_command() + _handle_codex_runtime() handler that
delegates to the shared module and renders results via _cprint.
gateway/run.py:
Dispatch in _handle_message() + _handle_codex_runtime_command() that
returns a string (gateway sends as message). On a successful change
that requires a new session, _evict_cached_agent() forces the next
inbound message to construct a fresh AIAgent with the new api_mode —
avoids prompt-cache invalidation mid-session.
gateway/run.py running-agent guard:
/codex-runtime joins /model in the early-intercept block so a runtime
flip mid-turn can't split a turn across two transports.
Tests:
tests/hermes_cli/test_codex_runtime_switch.py — 25 tests covering the
state machine: arg parsing (10 cases incl. case-insensitive and
synonyms), reading current runtime (5 cases incl. malformed configs),
writing runtime (3 cases), apply() entry point covering read-only,
no-op, codex-missing-blocked, codex-present-success, disable-no-binary-check,
and persist-failure paths (8 cases). All green.
Adjacent test suites confirm no regressions:
- tests/hermes_cli/test_commands.py + test_codex_runtime_switch.py:
167/167 green
- tests/agent/transports/: 283/283 green when combined with prior commits
Still missing: plugin migration helper, docs page, live e2e test gated on
codex binary. Followup commits.
* feat(codex-runtime): auto-migrate Hermes MCP servers to ~/.codex/config.toml
Translates the user's mcp_servers config from ~/.hermes/config.yaml into
the TOML format codex's MCP client expects. Wired into the
/codex-runtime codex_app_server enable path so users get their MCP tool
surface in the spawned subprocess automatically.
The migration runs on every enable. Failures are non-fatal — the runtime
change still proceeds and the user gets a warning so they can fix the
codex config manually.
What translates (mapping verified against codex-rs/core/src/config/edit.rs):
Hermes mcp_servers.<n>.command/args/env → codex stdio transport
Hermes mcp_servers.<n>.url/headers → codex streamable_http transport
Hermes mcp_servers.<n>.timeout → codex tool_timeout_sec
Hermes mcp_servers.<n>.connect_timeout → codex startup_timeout_sec
Hermes mcp_servers.<n>.cwd → codex stdio cwd
Hermes mcp_servers.<n>.enabled: false → codex enabled = false
What does NOT translate (warned + skipped per server):
Hermes-specific keys (sampling, etc.) — codex's MCP client has no
equivalent. Listed in the per-server skipped[] field of the report.
What's NOT migrated (intentional):
AGENTS.md — codex respects this file natively in its cwd. Hermes' own
AGENTS.md (project-level) is already in the worktree, so codex picks
it up without translation. No code needed.
Idempotency design:
All managed content lives between a 'managed by hermes-agent' marker
and the next non-mcp_servers section header. _strip_existing_managed_block
removes the prior managed region cleanly, preserving any user-added
codex config (model, providers.openai, sandbox profiles, etc.) above
or below.
Files added:
hermes_cli/codex_runtime_plugin_migration.py — pure-Python migration
helper. Public API: migrate(hermes_config, codex_home=None,
dry_run=False) returns MigrationReport with .migrated/.errors/
.skipped_keys_per_server. No external TOML dependency — minimal
formatter handles strings/numbers/booleans/lists/inline-tables.
tests/hermes_cli/test_codex_runtime_plugin_migration.py — 39 tests
covering:
- per-server translation (12): stdio/http/sse, cwd, timeouts,
enabled flag, command+url precedence, sampling drop, unknown keys
- TOML formatter (8): types, escaping, inline tables, error case
- existing-block stripping (4): no marker, alone, with user content
above, with user content below
- end-to-end migrate() (8): empty, dry-run, round-trip, idempotent
re-run, preserves user config, error reporting, invalid input,
summary formatting
Files changed:
hermes_cli/codex_runtime_switch.py — apply() now calls migrate() in
the codex_app_server enable branch. Migration failure logs a warning
in the result message but does NOT fail the runtime change. Disable
path (auto) explicitly skips migration.
tests/hermes_cli/test_codex_runtime_switch.py — 3 new tests:
test_enable_triggers_mcp_migration, test_disable_does_not_trigger_migration,
test_migration_failure_does_not_block_enable.
All 325 feature tests green:
- tests/agent/transports/: 249 (incl. 67 new)
- tests/run_agent/test_codex_app_server_integration.py: 9
- tests/hermes_cli/test_codex_runtime_switch.py: 28 (3 new)
- tests/hermes_cli/test_codex_runtime_plugin_migration.py: 39 (new)
* perf(codex-runtime): cache codex --version check within apply()
Single /codex-runtime invocation could spawn 'codex --version' up to 3
times (state report, enable gate, success message). Each spawn is ~50ms,
so the cumulative cost wasn't a crisis, but it was wasteful and turned a
trivial slash command into something noticeably laggy on slower systems.
Refactored to lazy-once via a closure over a nonlocal cache. First call
spawns; subsequent calls in the same apply() reuse the result.
Behavior unchanged — same return shape, same error handling, same install
hint when codex is missing. Just one subprocess per call instead of three.
Two regression-guard tests added:
- test_binary_check_cached_within_apply: enable path → call_count == 1
- test_binary_check_cached_on_read_only_call: state-report path → call_count == 1
Total tests for /codex-runtime now 30 (was 28); all 143 codex-runtime
tests still green.
* fix(codex-runtime): correct protocol field names found via live e2e test
Three real bugs caught only by running a turn end-to-end against codex
0.130.0 with a real ChatGPT subscription. Unit tests passed because they
asserted on our own (incorrect) wire shapes; the wire format from
codex-rs/app-server-protocol/src/protocol/v2/* is the source of truth and
my initial reading of the README was incomplete.
Bug 1: thread/start.permissions wire format
Was sending {"profileId": "workspace-write"}.
Real format per PermissionProfileSelectionParams enum (tagged union):
{"type": "profile", "id": "workspace-write"}
AND requires the experimentalApi capability declared during initialize.
AND requires a matching [permissions] table in ~/.codex/config.toml or
codex fails the request with 'default_permissions requires a [permissions]
table'.
Fix: stop overriding permissions on thread/start. Codex picks its default
profile (read-only unless user configures otherwise), which matches what
codex CLI users expect — they configure their default permission profile
in ~/.codex/config.toml the standard way. Trying to be clever about
profile selection broke every turn we tested.
Live error before fix: 'Invalid request: missing field type' on every
turn/start, even though our turn/start payload was correct — the field
codex was complaining about was inside the permissions sub-object we
shouldn't have been sending.
Bug 2: server-request method names
Was matching 'execCommandApproval' and 'applyPatchApproval'.
Real names per common.rs ServerRequest enum:
item/commandExecution/requestApproval
item/fileChange/requestApproval
item/permissions/requestApproval (new third method)
Fix: match the documented names. Added handler for
item/permissions/requestApproval that always declines — codex sometimes
asks to escalate permissions mid-turn and silent acceptance would surprise
users.
Live symptom before fix: agent.log showed
'Unknown codex server request: item/commandExecution/requestApproval'
and codex stalled because we replied with -32601 (unsupported method)
instead of an approval decision. The agent reported back 'The write
command was rejected' even though Hermes never showed the user an
approval prompt.
Bug 3: approval decision values
Was sending decision strings 'approved'/'approvedForSession'/'denied'.
Real values per CommandExecutionApprovalDecision enum (camelCase):
accept, acceptForSession, decline, cancel
(also AcceptWithExecpolicyAmendment and ApplyNetworkPolicyAmendment
variants we don't currently use).
Fix: rename _approval_choice_to_codex_decision return values; update
auto_approve_* fallbacks; update fail-closed default from 'denied' to
'decline'. Test mapping table updated to match.
Live test verified after fixes:
$ hermes (with model.openai_runtime: codex_app_server)
> Run the shell command: echo hermes-codex-livetest > .../proof.txt
then read it back
Approval prompt fired with 'Codex requests exec in <cwd>'.
User chose 'Allow once'. Codex executed the command, wrote the file,
read it back. Final response: 'Read back from proof.txt:
hermes-codex-livetest'. File contents on disk match.
agent.log confirms:
codex app-server thread started: id=019e200e profile=workspace-write
cwd=/tmp/hermes-codex-livetest/workspace
All 20 session tests still green after wire-format updates.
* fix(codex-runtime): correct apply_patch approval params + ship docs
Live e2e revealed FileChangeRequestApprovalParams doesn't carry the
changeset (just itemId, threadId, turnId, reason, grantRoot) — Codex's
'reason' field describes what the patch wants to do. Test config and
display logic updated to use it. The first 'apply_patch (0 change(s))'
display from the live test is now 'apply_patch: <reason>'.
Adds website/docs/user-guide/features/codex-app-server-runtime.md
covering enable/disable, prerequisites, approval UX, MCP migration
behavior, permission profile delegation to ~/.codex/config.toml, known
limitations, and the architecture diagram. Wired into the Automation
category in sidebars.ts.
Live e2e validation across the path matrix:
✓ thread/start handshake
✓ turn/start with text input
✓ commandExecution items + projection
✓ item/commandExecution/requestApproval → Hermes UI → response
✓ Approve once → command runs
✓ Deny → command rejected, codex falls back to read-only message
✓ Multi-turn (codex remembers prior turn's results)
✓ apply_patch via Codex's fileChange path
✓ item/fileChange/requestApproval → Hermes UI
✓ MCP server migration loads inside spawned codex (verified via
'use the filesystem MCP tool' prompt)
✓ /codex-runtime auto → codex_app_server toggle cycle
✓ Disable doesn't trigger migration
✓ Enable with codex CLI present succeeds + migrates
✓ Hermes-side interrupt path (turn/interrupt request issued cleanly
even if codex finishes before the interrupt lands)
Known live-validated limitations now documented in the docs page:
- delegate_task subagents unavailable on this runtime
- permission profile selection delegated to ~/.codex/config.toml
- apply_patch approval prompt has no inline changeset (codex protocol
doesn't expose it)
145/145 codex-runtime tests still green.
* feat(codex-runtime): native plugin migration + UX polish (quirks 2/4/5/10/11)
Major: migrate native Codex plugins (#7 in OpenClaw's PR list)
Discovers installed curated plugins via codex's plugin/list RPC and
writes [plugins."<name>@<marketplace>"] entries to ~/.codex/config.toml
so they're enabled in the spawned Codex sessions. This is the
'YouTube-video-worthy' bit Pash highlighted: when a user has
google-calendar, github, etc. installed in their Codex CLI, those
plugins activate automatically when they enable Hermes' codex runtime.
Implementation:
- hermes_cli/codex_runtime_plugin_migration.py: new _query_codex_plugins()
helper spawns 'codex app-server' briefly and walks plugin/list. Returns
(plugins, error) — failures are non-fatal so MCP migration still works.
- render_codex_toml_section() now takes plugins + permissions args.
- migrate() defaults: discover_plugins=True, default_permission_profile=
'workspace-write'. Explicit None on either disables that side.
- _strip_existing_managed_block() now also strips [plugins.*] and
[permissions]/[permissions.*] sections inside the managed block, so
re-runs replace plugins cleanly without touching codex's own config.
Quirk fixes:
#2 Default permissions profile written on enable.
Without this, Codex's read-only default kicks in and EVERY write
triggers an approval prompt. Now writes [permissions] default =
'workspace-write' so the runtime feels normal out of the box. Set
default_permission_profile=None to opt out.
#4 apply_patch approval prompt now shows what's changing.
Codex's FileChangeRequestApprovalParams doesn't carry the changeset.
Session adapter now caches the fileChange item from item/started
notifications and looks it up by itemId when codex requests approval.
Prompt shows '1 add, 1 update: /tmp/new.py, /tmp/old.py' instead of
'apply_patch (0 change(s))'.
Side benefit: also drains pending notifications BEFORE handling a
server request, so the projector and per-turn caches are up to date
when the approval decision fires. Bounded to 8 notifications per
loop iter to avoid starving codex's response.
#5/#10 Exec approval prompt never shows empty cwd.
When codex omits cwd in CommandExecutionRequestApprovalParams, fall
back to the session's cwd. If somehow neither is available, show
'<unknown>' explicitly instead of an empty string.
Also surfaces 'reason' from the approval params when codex provides
it — gives users more context on why codex wants to run something.
#11 Banner indicates the codex_app_server runtime when active.
New 'Runtime: codex app-server (terminal/file ops/MCP run inside
codex)' line appears in the welcome banner only when the runtime is
on. Default banner is unchanged.
Tests:
- 7 new tests in test_codex_runtime_plugin_migration.py covering
plugin discovery (mocked), failure handling, dry-run skip, opt-out
flag, idempotent re-runs, and permissions writing.
- 3 new tests in test_codex_app_server_session.py covering the
enriched approval prompts: cwd fallback, change summary on
apply_patch, fallback when no item/started cache exists.
- All 26 session tests + 46 migration tests green; 153 total in PR.
* feat(codex-runtime): hermes-tools MCP callback + native plugin migration
The big architectural addition: when codex_app_server runtime is on,
Hermes registers its own tool surface as an MCP server in
~/.codex/config.toml so the codex subprocess can call back into Hermes
for tools codex doesn't ship with — web_search, browser_*, vision,
image_generate, skills, TTS.
Also: 'migrate native codex plugins' (Pash's YouTube-video-worthy bit) —
when the user has plugins like Linear, GitHub, Gmail, Calendar, Canva
installed via 'codex plugin', Hermes discovers them via plugin/list and
writes [plugins.<name>@openai-curated] entries so they activate
automatically.
New module: agent/transports/hermes_tools_mcp_server.py
FastMCP stdio server exposing 17 Hermes tools. Each call dispatches
through model_tools.handle_function_call() — same code path as the
Hermes default runtime. Run with:
python -m agent.transports.hermes_tools_mcp_server [--verbose]
Exposed: web_search, web_extract, browser_navigate / _click / _type /
_press / _snapshot / _scroll / _back / _get_images / _console /
_vision, vision_analyze, image_generate, skill_view, skills_list,
text_to_speech.
NOT exposed (deliberately):
- terminal/shell/read_file/write_file/patch — codex has built-ins
- delegate_task/memory/session_search/todo — _AGENT_LOOP_TOOLS in
model_tools.py:493, require running AIAgent context. Documented
as a limitation and surfaced in the slash command output.
Migration changes (hermes_cli/codex_runtime_plugin_migration.py):
- _query_codex_plugins() spawns 'codex app-server' briefly to walk
plugin/list and pull installed openai-curated plugins. Failures are
non-fatal — MCP migration still completes.
- render_codex_toml_section() now takes plugins + permissions args
AND wraps the managed block with a MIGRATION_END_MARKER comment so
the stripper can reliably find both ends, even when the block
contains top-level keys (default_permissions = ...).
- migrate() defaults: discover_plugins=True, expose_hermes_tools=True,
default_permission_profile=':workspace' (built-in codex profile name
— must be prefixed with ':'). All three opt-out via explicit args.
- _build_hermes_tools_mcp_entry() builds the codex stdio entry with
HERMES_HOME and PYTHONPATH passthrough so a worktree-launched
Hermes points the MCP subprocess at the same module layout.
Live-caught wire bugs fixed during this turn:
1. Permission profile config key is top-level , NOT a [permissions] table. The [permissions] table is
for *user-defined* profiles with structured fields. Built-in
profile names start with ':' (':workspace', ':read-only',
':danger-no-sandbox'). Was emitting
which codex rejected with 'invalid type: string "X", expected
struct PermissionProfileToml'.
2. Built-in profile is , NOT . Codex
rejected with 'unknown built-in profile'.
3. Codex's MCP layer sends for
tool-call confirmation. We weren't handling it, so codex stalled
and returned 'MCP tool call was rejected'. Now: auto-accept for
our own hermes-tools server (user already opted in by enabling
the runtime), decline for third-party servers.
Quirk fixes shipped (from the limitations list):
#2 default permissions: workspace profile written on enable. No more
approval prompt on every write.
#4 apply_patch approval shows what's changing: cache fileChange
items from item/started, look up by itemId when codex sends
item/fileChange/requestApproval. Prompt: '1 add, 1 update:
/tmp/new.py, /tmp/old.py' instead of '0 change(s)'.
#5/#10 exec approval cwd never empty: fall back to session cwd, then
'<unknown>'. Also surfaces 'reason' from codex when present.
#11 banner shows 'Runtime: codex app-server' line when active so
users understand why tool counts may not match what's reachable.
Tests:
- 5 new tests in test_codex_runtime_plugin_migration.py covering
plugin discovery, expose_hermes_tools entry generation, idempotent
re-runs, opt-out flag, permissions profile.
- 3 new tests in test_codex_app_server_session.py covering enriched
approval prompts (cwd fallback, fileChange summary).
- 2 new tests for mcpServer/elicitation/request handling (accept
hermes-tools, decline others).
- New test file test_hermes_tools_mcp_server.py covering module
surface, EXPOSED_TOOLS safety invariants (no shell/file_ops,
no agent-loop tools), and main() error paths.
- 166 codex-runtime tests total, all green.
Live e2e validated against codex 0.130.0 + ChatGPT subscription:
✓ /codex-runtime codex_app_server enables, migrates filesystem MCP,
registers hermes-tools, writes default_permissions = ':workspace'
✓ Banner shows 'Runtime: codex app-server' line in subsequent sessions
✓ Shell command runs without approval prompt (workspace profile works)
✓ Multi-turn — codex remembers prior turn's results
✓ apply_patch path via fileChange request approval
✓ web_search via hermes-tools MCP callback returns real Firecrawl
results: 'OpenAI Codex CLI – Getting Started' end-to-end in 13s
✓ Disable cycle clean
Docs updated: website/docs/user-guide/features/codex-app-server-runtime.md
Full re-write covering native plugin migration, the hermes-tools
callback architecture, the prerequisites change ('codex login is
separate from hermes auth login codex'), the trade-off table now
reflecting which Hermes tools work via callback, and the limitations
list updated with what's actually unavailable on this runtime.
* feat(codex-runtime): pin user-config preservation invariant for quirk #6
Quirk #6 from the limitations list — user MCP servers / overrides /
codex-only sections in ~/.codex/config.toml that live OUTSIDE the
hermes-managed block must survive re-migration verbatim.
This already worked thanks to the MIGRATION_MARKER + MIGRATION_END_MARKER
pair I added when fixing the default_permissions wire format (so the
strip can find both ends of the managed region even with top-level
keys like default_permissions). But it was an emergent property
without a test pinning it.
Now explicitly tested:
- User MCP server above the managed block survives migration
- User MCP server below the managed block survives migration
- Both above + below survive a second re-migration
- User content (model, providers, sandbox, otel, etc.) outside our
region is left untouched
Docs added a section "Editing ~/.codex/config.toml safely" explaining
the marker contract — so users know they can add their own MCP
servers, override permissions, configure codex-only options, etc.
without fear of Hermes overwriting their work.
167 codex-runtime tests, all green.
* docs(codex-runtime): clarify the actual tool surface — shell covers terminal/read/write/find
Previous docs and PR description undersold what codex's built-in
toolset actually provides. apply_patch alone made it sound like the
runtime could only edit files in patch format — implying you'd lose
terminal use, read_file, write_file, search/find. That was wrong.
Codex's 'shell' tool runs arbitrary shell commands inside the sandbox,
which covers everything you'd do in bash: cat/head/tail (read), echo>
or heredocs (write), find/rg/grep (search), ls/cd (navigate), build/
test/git/etc. apply_patch is for structured multi-file edits on top
of that. update_plan is its in-runtime todo. view_image loads images.
And codex has its own web_search built in (in addition to the
Firecrawl-backed one Hermes exposes via MCP callback).
Docs now have a 'What tools the model actually has' section right
after Why, breaking the surface into three clearly-labeled buckets:
1. Codex's built-in toolset (always on) — shell, apply_patch,
update_plan, view_image, web_search; covers everything terminal-
adjacent.
2. Native Codex plugins (auto-migrated from your codex plugin
install) — Linear, GitHub, Gmail, Calendar, Outlook, Canva, etc.
3. Hermes tool callback (MCP server in ~/.codex/config.toml) —
web_search/web_extract via Firecrawl, browser_*, vision_analyze,
image_generate, skill_view/skills_list, text_to_speech.
Plus a 'What's NOT available' callout listing the four agent-loop tools
(delegate_task, memory, session_search, todo) that need running
AIAgent context and can't reach the codex runtime.
Trade-offs table broken out: shell, apply_patch, update_plan,
view_image, sandbox each get their own row with a one-line description
so users can see at a glance what's available natively.
Architecture diagram updated to list the codex built-ins by name
instead of 'apply_patch + shell + sandbox'.
No code changes — purely docs clarification. 167 codex-runtime tests
still green.
* fix(codex-runtime): _spawn_background_review signature + review fork api_mode downgrade
Two real bugs in the self-improvement loop integration that the previous
test mocked away.
Bug 1: wrong call signature
The codex helper was calling self._spawn_background_review() with no
args after every turn. That function actually requires:
messages_snapshot=list (positional or keyword)
review_memory=bool (at least one trigger must be True)
review_skills=bool
So the call would have raised TypeError at runtime — except the only
test that exercised this path mocked _spawn_background_review entirely
and just asserted spawn.called, so the wrong-arg shape never surfaced.
Bug 2: review fork inherits codex_app_server api_mode
The review fork is constructed with:
api_mode = _parent_runtime.get('api_mode')
So when the parent is codex_app_server, the review fork ALSO runs as
codex_app_server. But the review fork's whole job is to call agent-loop
tools (memory, skill_manage) which require Hermes' own dispatch — they
short-circuit with 'must be handled by the agent loop' on the codex
runtime. So the review fork would have run, decided to save something,
called memory or skill_manage, and silently no-op'd.
Fixed in run_agent.py:_spawn_background_review() — when the parent
api_mode is 'codex_app_server', the review fork is downgraded to
'codex_responses' (same OAuth credentials, same openai-codex provider,
but talks to OpenAI's Responses API directly so Hermes owns the loop).
Also rewrote the codex helper's review wiring to match the
chat_completions path:
- Computes _should_review_memory in the pre-loop block (was already
being computed; now passed through to the helper as an arg).
- Computes _should_review_skills AFTER the codex turn returns +
counters tick (line ~15432 pattern in chat_completions).
- Calls _spawn_background_review(messages_snapshot=, review_memory=,
review_skills=) only when at least one trigger fires.
- Adds the external memory provider sync (_sync_external_memory_for_turn)
that the chat_completions path runs after every turn.
Tests:
Replaced the broken test_background_review_invoked (which only
asserted spawn.called) with three sharper tests:
- test_background_review_NOT_invoked_below_threshold:
single turn at default thresholds → no review fires (would have
caught the original 'every turn calls spawn with no args' bug)
- test_background_review_skill_trigger_fires_above_threshold:
10 tool_iterations at threshold=10 → review fires with
messages_snapshot=list, review_skills=True, counter resets
- test_background_review_signature_never_breaks: regression guard
asserting positional args are always empty and kwargs include
messages_snapshot
New TestReviewForkApiModeDowngrade class:
- test_codex_app_server_parent_downgrades_review_fork: drives the
real _spawn_background_review function (no mock at that level),
asserts the review_agent gets api_mode='codex_responses' when
the parent was codex_app_server.
Live-validated against real run_conversation:
- Counter ticked from 0 to 5 after a 5-tool-iteration turn
- _spawn_background_review fired exactly once with kwargs-only signature
- review_skills=True, review_memory=False
- messages_snapshot was 12 entries (5 assistant tool_calls + 5 tool
results + 1 final assistant + initial system/user)
- Counter reset to 0 after fire
170 codex-runtime tests, all green.
Docs: added a Self-improvement loop section to the codex runtime page
explaining both how the trigger logic stays equivalent and that the
review fork is auto-downgraded to codex_responses for the agent-loop
tools. Also clarified that apply_patch and update_plan ARE codex's
built-in tools (the previous version made it sound like they were
separate from 'codex's stuff' — they're not, all five tools listed
in 'What tools the model actually has' section 1 are codex built-ins).
* feat(codex-runtime): expose kanban tools through Hermes MCP callback
Kanban workers spawn as separate hermes chat -q subprocesses that read
the user's config.yaml. If model.openai_runtime: codex_app_server is set
globally (which is the whole point of opt-in), every dispatched worker
ALSO comes up on the codex runtime.
That mostly works — codex's built-in shell + apply_patch + update_plan
do the actual task work fine — but it had one critical break: the
worker handoff tools (kanban_complete, kanban_block, kanban_comment,
kanban_heartbeat) are Hermes-registered tools, not codex built-ins.
On the codex runtime, codex builds its own tool list and these never
reach the model, so the worker would do the work but not be able to
report back, hanging until the dispatcher's timeout escalates it as
zombie.
Fix: add all 9 kanban tools to the EXPOSED_TOOLS list in the Hermes
MCP callback. They dispatch statelessly through handle_function_call()
just like web_search and the others — they read HERMES_KANBAN_TASK
from env (set by the dispatcher), gate correctly (worker tools require
the env var, orchestrator tools require it unset), and write to
~/.hermes/kanban.db.
Why kanban tools work via stateless dispatch when delegate_task/memory/
session_search/todo don't: those four are listed in _AGENT_LOOP_TOOLS
(model_tools.py:493) and short-circuit in handle_function_call() with
'must be handled by the agent loop' — they need to mutate AIAgent's
mid-loop state. Kanban tools have no such requirement; they're pure
side-effect functions against the kanban.db plus state_meta.
Tools exposed:
Worker handoff (require HERMES_KANBAN_TASK):
kanban_complete, kanban_block, kanban_comment, kanban_heartbeat
Read-only board queries:
kanban_show, kanban_list
Orchestrator (require HERMES_KANBAN_TASK unset):
kanban_create, kanban_unblock, kanban_link
Tests:
- test_kanban_worker_tools_exposed: complete/block/comment/heartbeat
in EXPOSED_TOOLS (regression guard for the would-hang-worker bug)
- test_kanban_orchestrator_tools_exposed: create/show/list/unblock/link
Docs:
- New 'Workflow features' section in the docs page covering /goal,
kanban, and cron behavior on this runtime
- /goal: works fully via run_conversation feedback; only caveat is
approval-prompt noise on long writes-heavy goals (mitigated by
the default :workspace permission profile)
- Kanban: enumerated which tools are reachable via the callback and
why the env var propagates correctly through the codex subprocess
to the MCP server subprocess
- Cron: documented as 'not specifically tested' — same rules as the
CLI apply since cron runs through AIAgent.run_conversation
- Trade-offs table gained rows for /goal, kanban worker, kanban
orchestrator
172/172 codex-runtime tests green (+2 from kanban tests).
* docs(codex-runtime): wire /codex-runtime into slash-commands ref + flag aux token cost
Three docs gaps caught during a final audit:
1. /codex-runtime was only in the feature docs page, not in the
slash-commands reference. Added rows to both the CLI section and
the Messaging section so users discover it where they'd look for
slash command syntax.
2. CODEX_HOME and HERMES_KANBAN_TASK weren't in environment-variables.md.
CODEX_HOME lets users redirect Codex CLI's config dir (the migration
honors it). HERMES_KANBAN_TASK is set by the kanban dispatcher and
propagates to the codex subprocess + the hermes-tools MCP subprocess
so kanban worker tools gate correctly — documented as 'don't set
manually' since it's an internal handoff.
3. Aux client behavior on this runtime. When openai_runtime=
codex_app_server is on with the openai-codex provider, every aux
task (title generation, context compression, vision auto-detect,
session search summarization, the background self-improvement review
fork) flows through the user's ChatGPT subscription by default.
This is true for the existing codex_responses path too, but it's
more visible / important here because users explicitly opted in for
subscription billing. Added a 'Auxiliary tasks and ChatGPT
subscription token cost' section to the docs page with a YAML
example showing how to override specific aux tasks to a cheaper
model (typically google/gemini-3-flash-preview via OpenRouter).
Also documents how the self-improvement review fork gets
auto-downgraded from codex_app_server to codex_responses by the
fix earlier in this PR.
No code changes — pure docs. 172 codex-runtime tests still green.
* docs+test(codex-runtime): pin HOME passthrough, document multi-profile + CODEX_HOME
OpenClaw hit a real footgun in openclaw/openclaw#81562: when spawning
codex app-server they were synthesizing a per-agent HOME alongside
CODEX_HOME. That made every subprocess codex's shell tool launches
(gh, git, aws, npm, gcloud, ...) see a fake $HOME and miss the user's
real config files. They had to back it out in PR #81562 — keep
CODEX_HOME isolation, leave HOME alone.
Audit confirms Hermes' codex spawn doesn't have this problem. We do
os.environ.copy() and only overlay CODEX_HOME (when provided) and
RUST_LOG. HOME passes through unchanged. But it was an emergent
property without a test pinning it, so adding a regression guard:
test_spawn_env_preserves_HOME — confirms parent HOME survives intact
in the subprocess env
test_spawn_env_sets_CODEX_HOME_when_provided — confirms codex_home
arg still isolates
codex state correctly
Docs additions:
'HOME environment variable passthrough' section — calls out the
contract explicitly: CODEX_HOME isolates codex's own state, HOME
stays user-real so gh/git/aws/npm/etc. find their normal config.
Cites openclaw#81562 as the cautionary tale.
'Multi-profile / multi-tenant setups' section — addresses the
related concern: profiles share ~/.codex/ by default. For users who
want per-profile codex isolation (separate auth, separate plugins),
documents the manual CODEX_HOME=<profile-scoped-dir> approach.
Explains why we DON'T auto-scope CODEX_HOME per profile: doing so
would silently invalidate existing codex login state for anyone
upgrading to this PR with tokens already at ~/.codex/auth.json.
Opt-in is safer than surprising users.
174 codex-runtime tests (+2 from HOME guards), all green.
* fix(codex-runtime): TOML control-char escapes + atomic config.toml write
Two footguns caught in a final audit pass before merge.
Bug 1: TOML control characters not escaped
The _format_toml_value() helper escaped backslashes and double quotes
but passed literal control characters (\n, \t, \r, \f, \b) through
unchanged. TOML basic strings don't allow literal control characters
— a path or env var containing a newline would produce invalid TOML
that codex refuses to load.
Realistic exposure: pathological cases like a HERMES_HOME with a
trailing newline (env var concatenation accident), or a PYTHONPATH
with a tab from a multi-line shell heredoc.
Fix: escape all five TOML basic-string control sequences (\b \t \n
\f \r) in addition to \\ and \" that we already did. Order
matters — backslash must come first or the other escapes get
re-escaped.
Bug 2: config.toml write wasn't atomic
If the python process crashed between target.mkdir() and the
write_text() finishing, a half-written config.toml could be left
behind. On NFS / Windows / some FUSE mounts this is a real concern;
on ext4/APFS small writes are usually atomic in practice but not
guaranteed.
Fix: write to a tempfile.mkstemp() temp file in the same directory,
then Path.replace() (atomic same-dir rename on POSIX, ReplaceFile on
Windows). On rename failure, clean up the temp file so repeated
failed migrations don't pile up .config.toml.* files.
Tests:
- test_string_with_newline_escaped — \n in value → \n in output
- test_string_with_tab_escaped — \t in value → \t in output
- test_string_with_other_controls_escaped — \r, \f, \b
- test_windows_path_escaped_correctly — backslash doubling
- test_atomic_write_no_temp_leak_on_success — no .config.toml.*
left over after a successful write
- test_atomic_write_cleanup_on_rename_failure — temp file removed
when Path.replace raises (simulated disk full)
180 codex-runtime tests, all green (+6 from this commit).
Footguns audited but NOT fixed (with rationale):
- Concurrent migrations race. Two Hermes processes hitting
/codex-runtime codex_app_server within seconds of each other could
cause one writer to lose entries. Low probability (you'd have to
enable from two surfaces simultaneously) and low impact (just re-run
migration). Adding fcntl/msvcrt locking is more code than it's
worth here. The atomic rename above means each individual write is
consistent — only the merge step is racy.
- Codex protocol version drift. We pin MIN_CODEX_VERSION=0.125 and
check at runtime but don't reject too-new versions. Right call —
the protocol has been stable through 0.125 → 0.130. If OpenAI
breaks it later we'd see the error in test_codex_app_server_runtime
on CI before users hit it.
