Removes the 'Launch hermes chat now? (Y/n)' prompt at the end of
hermes setup. The summary already prints 'Ready to go! → hermes'
so the auto-launch was redundant, and on macOS 26+ it could crash
in prompt_toolkit when setup was invoked from the curl install
script with stdin redirected from /dev/tty (#5884, #6128).
After setup, users run 'hermes' themselves like every other CLI
tool. Same pattern applies to the Windows installer.
Closes#6128 (narrower env-var-guarded fix superseded by removing
the prompt outright).
Adds an explicit API compatibility mode prompt to the `hermes model -> custom`
flow so Codex-compatible third-party endpoints (and any other non-default
backend whose URL doesn't match the existing heuristics in
`_detect_api_mode_for_url`) can be selected explicitly instead of silently
falling back to chat_completions.
Choices: Auto-detect / chat_completions / codex_responses / anthropic_messages.
Persists `api_mode` to:
- `model.api_mode` (active session config)
- the matching `custom_providers[*]` entry (so re-activating the named
provider next time replays the same transport)
Salvaged from PR #6125 onto current main: kept the new prompt and the
`_save_custom_provider(api_mode=...)` plumbing; the named-custom flow
already extracts and applies `api_mode` from the saved entry on current
main so those changes are preserved as-is. Test fixtures updated for the
new prompt and the existing display-name prompt.

These two functions in hermes_cli/profiles.py have no callers — the live
`hermes completion {bash,zsh}` command uses hermes_cli/completion.py's
generate_bash() / generate_zsh() instead. Multiple PRs (incl. #6141) tried
to fix the trailing-`_hermes "$@"` zsh bug here, only to discover the
patch never reached users. Delete the dead code so future contributors
patch the right file.
The actual user-facing fix lives in the preceding cherry-picked commits
to hermes_cli/completion.py.
* feat(nous): unified client=hermes-client-v<version> tag on every Portal request
Every Hermes request to Nous Portal now carries the same
client=hermes-client-v<__version__> tag (e.g. client=hermes-client-v0.13.0
on this release), sourced live from hermes_cli.__version__. The release
script's regex bump auto-aligns it on every release.
Centralized in agent/portal_tags.py and wired into all four call sites:
- NousProfile.build_extra_body (main agent loop, every chat completion)
- auxiliary_client.NOUS_EXTRA_BODY + _build_call_kwargs (aux client)
- run_agent.py compression-summary fallback path
- tools/web_tools.py web_extract fallback
Replaces the client=aux marker added in #24194 with the unified version
tag. Tests assert against the helper output (invariant) rather than the
literal string, so they don't need updating on every release.
* feat(nous): cover /goal judge and kanban specify aux paths
Two aux-using surfaces bypassed call_llm by invoking
client.chat.completions.create() directly without extra_body, so they
were missing the unified Portal client tag:
- hermes_cli/goals.py — /goal standing-goal judge
- hermes_cli/kanban_specify.py — kanban triage specifier
Both now pass extra_body=get_auxiliary_extra_body() or None so they
inherit the version tag when the aux client points at Nous Portal, and
emit nothing otherwise (no tag leak to OpenRouter/Anthropic auxes).
The long-lived prefix-cache layout split the system prompt into stable/
context/volatile blocks and re-derived them on every API call. The
volatile tier (timestamp + memory snapshot + USER profile) ticks per
turn, so the system message bytes mutated mid-conversation and broke
upstream prompt caches (OpenRouter, Nous Portal, Anthropic).
Diagnosed via live wire-format diffing: an 8-turn conversation showed
OLD layout flipping system block[1] sha mid-session at the minute
boundary, dropping cached_tokens to 0 on that turn (cumulative
66.6% vs 83.3% for the single-block layout). Hermes invariant:
history (system + all but the last 1-2 messages) must be static.
Fix: drop the long-lived layout entirely. Single layout everywhere —
system_and_3 with one cached system string built once on first turn,
replayed verbatim on every subsequent turn. Loses cross-session 1h
prefix caching for Claude (the feature that motivated the split), but
within-session caching now actually works on every provider.
Removed:
- run_agent.py: _use_long_lived_prefix_cache flag, _long_lived_cache_ttl,
_supports_long_lived_anthropic_cache method, the long-lived branch in
run_conversation, mark_tools_for_long_lived_cache call site
- agent/prompt_caching.py: apply_anthropic_cache_control_long_lived,

Targeted tests: 62/62 pass.
The test_restart_command_while_busy_requests_drain_without_interrupt test
was asserting against a hardcoded emoji string that was valid before the
i18n migration. After gateway/run.py switched to t("gateway.draining",
count=N), the test sees the translated output (or the raw key when the
locale catalog isn't resolved in xdist workers).
Fix by asserting against t("gateway.draining", count=1) — this produces
the correct expected value regardless of whether the locale file is
available in the test environment.
PR #24151 routed Portal Qwen (qwen3.6-plus) through the prefix_and_2
long-lived cache layout, attaching {"type":"ephemeral","ttl":"1h"}
markers to the tools[-1] entry and the stable system-prefix block.
That layout works for Portal Claude because Anthropic / OpenRouter on
Anthropic routes honour 1h TTL — but Portal Qwen ultimately proxies to
Alibaba DashScope, which documents a single "ephemeral" TTL of 5
minutes on its Context Cache. The ttl="1h" qualifier is silently
dropped upstream, so the two highest-value breakpoints (tools array +
system prefix) never land. Only the rolling-window 5m markers on the
last 2 messages cache, which matches the observed ~25% read rate.
Fix: keep Portal Qwen on cache_control via _anthropic_prompt_cache_policy
returning (True, False), but drop it from _supports_long_lived_anthropic_cache
so it rides the standard system_and_3 5m layout (system + last 3 messages,
all at 5m). Same 4 breakpoints, all in a TTL the upstream actually honours.

Three follow-ups to PR #24168 found during live E2E testing on TS/bash files:
1. typescript-language-server now installs the typescript SDK (tsserver)
alongside it. Without that sibling install, initialize() failed with
"Could not find a valid TypeScript installation" and the server was
marked broken — no diagnostics ever reached the agent. New extra_pkgs
field on INSTALL_RECIPES makes that explicit and reusable for future
peer-dep cases.
2. _check_lint now treats "linter command exists on PATH but cannot
actually run" as skipped instead of error. The motivating case is
npx tsc when typescript is not in node_modules — npx prints its
"This is not the tsc command you are looking for" banner and exits
non-zero, which previously blocked the LSP semantic tier (gated on
success or skipped). Pattern-matched per base command (npx,
rustfmt, go) so genuine lint errors still flow through normally.
3. hermes lsp status now surfaces a Backend warnings section when
bash-language-server is installed but shellcheck is missing. The
server itself spawns fine but bash-language-server delegates
diagnostics to shellcheck — without it on PATH the integration
looks alive but never reports any problems. Same warning is
logged once at server spawn time.
Validation:
- 12 new tests in tests/agent/lsp/test_install_and_lint_fixes.py:
* recipe carries typescript SDK
* _install_npm passes both pkg + extras to npm CLI
* backwards compat: recipes without extras still work
* _backend_warnings quiet when bash absent / both present
* _backend_warnings fires when bash installed without shellcheck
* status output includes the Backend warnings section
* _looks_like_linter_unusable catches the npx tsc banner
* real TS type errors not misclassified as unusable
* unfamiliar linters fall through normally
* _check_lint returns skipped on npx tsc unusable
* _check_lint returns error on real tsc type errors
- Full lsp + file_operations test suite: 245/245 pass
- Live E2E:
* try_install("typescript-language-server") installs both packages
into node_modules
* write_file(bad.ts, ...) returns lint=skipped + lsp_diagnostics
with two real TS errors (was lint=error, no lsp_diagnostics)
* hermes lsp status renders the shellcheck warning when bash is
installed but shellcheck is not on PATH
When the user runs /stop or a session is interrupted mid-flight, the
👀 in-progress reaction lingered on the user's message indefinitely.
Without another agent run to swap it for 👍/👎, the eyes stayed there
forever — visually misleading (looks like the agent is still working).
Fix: on ProcessingOutcome.CANCELLED, call set_message_reaction with
reaction=None to clear all reactions on the message. Documented Bot API
semantics (equivalent to Bot API 10.0's deleteMessageReaction, but works
on PTB 22.6 already without the version bump).
Test changes:
- Renamed test_on_processing_complete_cancelled_keeps_existing_reaction
→ test_on_processing_complete_cancelled_clears_reaction; updated
assertion to expect set_message_reaction(reaction=None).
- Added test_on_processing_complete_cancelled_skipped_when_disabled
(TELEGRAM_REACTIONS=false short-circuits).
- Added test_clear_reactions_handles_api_error_gracefully and
test_clear_reactions_returns_false_without_bot to cover the new
_clear_reactions helper.
Built-in commands with required args (e.g. /queue, /steer, /background)
were excluded from Telegram setMyCommands output, making them invisible
in the autocomplete menu. However, their handlers already return usage
text when invoked without arguments, so hiding them hurts discoverability.
This commit removes the _requires_argument filter for built-in commands
(COMMAND_REGISTRY) while keeping it for plugin-registered slash commands,
which may not provide a no-arg usage fallback.
Closes#24312
The clarify tool returned 'not available in this execution context' for
every gateway-mode agent because gateway/run.py never passed
clarify_callback into the AIAgent constructor. Schema actively encouraged
calling it; users never saw the question.
Changes:
- tools/clarify_gateway.py — new event-based primitive mirroring
tools/approval.py: register/wait_for_response/resolve_gateway_clarify
with per-session FIFO, threading.Event blocking with 1s heartbeat
slices (so the inactivity watchdog keeps ticking), and
clear_session for boundary cleanup.
- gateway/platforms/base.py — abstract send_clarify with a numbered-text
fallback so every adapter (Discord, Slack, WhatsApp, Signal, Matrix,
etc.) gets a working clarify out of the box. Plus an active-session
bypass: when the agent is blocked on a text-awaiting clarify, the next
non-command message routes inline to the runner's intercept instead
of being queued + triggering an interrupt. Same shape as the /approve
deadlock fix from PR #4926.
- gateway/platforms/telegram.py — concrete send_clarify renders one
inline button per choice plus '✏️ Other (type answer)'. cl: callback
handler resolves numeric choices immediately, flips to text-capture
mode for Other, with the same authorization guards as exec/slash
approvals.
- gateway/run.py — clarify_callback wired at the cached-agent per-turn
callback assignment site (only the user-facing agent path; cron and
hygiene-compress agents have no human attached). Bridges sync→async
via run_coroutine_threadsafe, blocks with the configured timeout, and
returns a '[user did not respond within Xm]' sentinel on timeout so
the agent adapts rather than pinning the running-agent guard. Text-
intercept added to _handle_message before slash-confirm intercept
(skipping slash commands). clear_session called in the run's finally
to cancel any orphan entries.
- hermes_cli/config.py — agent.clarify_timeout default 600s.
- website/docs/user-guide/messaging/telegram.md — Interactive Prompts
section.
Tests:
- tests/tools/test_clarify_gateway.py (14 tests) — full primitive
coverage: button resolve, open-ended auto-await, Other flip, timeout
None, unknown-id idempotency, clear_session cancellation, FIFO
ordering, register/unregister notify, config default.
- tests/gateway/test_telegram_clarify_buttons.py (12 tests) — render
paths (multi-choice/open-ended/long-label/HTML-escape/not-connected),
callback dispatch (numeric resolve/Other flip/already-resolved/
unauthorized/invalid-token), and base-adapter text fallback.
Out of scope: bot-to-bot, guest mode, checklists, poll media, live
photos. Closes#24191.
PR #24500 introduced stale-lock detection that calls
`_looks_like_gateway_process` to confirm a running PID is not an
unrelated process that reused the slot. On Windows neither `/proc`
nor `ps` is available, so `_read_process_cmdline` always returns
`None` and `_looks_like_gateway_process` always returns `False` —
causing every valid Windows gateway lock to be marked stale and
immediately evicted.
Fix: after `_looks_like_gateway_process` returns `False`, call
`_read_process_cmdline` directly. If the result is non-`None` the
live cmdline was readable and confirms the PID is foreign → stale.
If it is `None` (cmdline unreadable, e.g. Windows without ps), fall
back to `_record_looks_like_gateway` which validates the stored
`argv` the gateway wrote into the lock file at startup. Both
oracles must say "not a gateway" before the lock is evicted — the
same two-oracle pattern already used in `get_running_pid` (line 941).
Adds a regression test that simulates a Windows host where
`_looks_like_gateway_process` returns `False` for every PID and
`_read_process_cmdline` returns `None`, confirming the lock is kept
when the record's argv identifies it as a gateway process.
deepseek-v4-pro has been routable since v0.12 but was missing from
the _OFFICIAL_DOCS_PRICING table. Sessions using this model showed
as "unknown cost" in hermes insights instead of a dollar estimate.
Add pricing entry using published list prices:
- input: \$1.74/M tokens
- output: \$3.48/M tokens

Uses standard list rates (not the 75% promo) so estimates remain
accurate after promo expires 2026-05-31.

* feat(lsp): semantic diagnostics from real language servers in write_file/patch
Wire ~26 language servers (pyright, gopls, rust-analyzer, typescript-language-server,
clangd, bash-language-server, ...) into the post-write lint check used by write_file
and patch. The model now sees type errors, undefined names, missing imports, and
project-wide semantic issues introduced by its edits, not just syntax errors.
LSP is gated on git workspace detection: when the agent's cwd or the file being
edited is inside a git worktree, LSP runs against that workspace; otherwise the
existing in-process syntax checks are the only tier. This keeps users on
user-home cwds (Telegram/Discord gateway chats) from spawning daemons.
The post-write check is layered: in-process syntax check first (microseconds),
then LSP semantic diagnostics second when syntax is clean. Diagnostics are
delta-filtered against a baseline captured at write start, so the agent only
sees errors its edit introduced. A flaky/missing language server can never
break a write -- every LSP failure path falls back silently to the syntax-only
result.
New module agent/lsp/ split into:
- protocol.py: Content-Length JSON-RPC framer + envelope helpers
- client.py: async LSPClient (spawn, initialize, didOpen/didChange,
ContentModified retry, push/pull diagnostic stores)
- workspace.py: git worktree walk-up + per-server NearestRoot resolver
- servers.py: registry of 26 language servers (extension match,
root resolver, spawn builder per language)
- install.py: auto-install dispatch (npm install --prefix, go install
with GOBIN, pip install --target) into HERMES_HOME/lsp/bin/
- manager.py: LSPService (per-(server_id, root) client registry, lazy
spawn, broken-set, in-flight dedupe, sync facade for tools layer)
- reporter.py: <diagnostics> block formatter (severity-1-only, 20-per-file)
- cli.py: hermes lsp {status,list,install,install-all,restart,which}
Wired into tools/file_operations.py:
- write_file/patch_replace now call _snapshot_lsp_baseline before write
- _check_lint_delta gains a third tier: LSP semantic diagnostics when
syntax is clean
- All LSP code paths swallow exceptions; write_file's contract unchanged
Config: 'lsp' section in DEFAULT_CONFIG with enabled (default true),
wait_mode, wait_timeout, install_strategy (default 'auto'), and per-server
overrides (disabled, command, env, initialization_options).
Tests: tests/agent/lsp/ -- 49 tests covering protocol framing (encode and
read_message round-trip, EOF/truncation/missing Content-Length), workspace
gate (git walk-up, exclude markers, fallback to file location), reporter
(severity filter, max-per-file cap, truncation), service-level delta filter,
and an in-process mock LSP server that exercises the full client lifecycle
including didChange version bumps, dedup, crash recovery, and idempotent
teardown.
Live E2E verified end-to-end through ShellFileOperations: pyright
auto-installed via npm into HERMES_HOME, baseline captured, type error
introduced, single delta diagnostic surfaced with correct line/column/code/
source, then patch fix removes the diagnostic from the output.
Docs: new website/docs/user-guide/features/lsp.md page covering supported
languages, configuration knobs, performance characteristics, and
troubleshooting; cli-commands.md updated with the 'hermes lsp' reference;
sidebar updated.
* feat(lsp): structured logging, backend gate, defensive walk caps
Cherry-picks the substantive ideas from #24155 (different scope, same
problem space) onto our PR.
agent/lsp/eventlog.py (new): dedicated structured logger
``hermes.lint.lsp`` with steady-state silence. Module-level dedup sets
keep a 1000-write session at exactly ONE INFO line ("active for
<root>") at the default INFO threshold; clean writes log at DEBUG so
they never reach agent.log under normal config. State transitions
(server starts, no project root for a file, server unavailable) fire
at INFO/WARNING once per (server_id, key); novel events (timeouts,
unexpected errors) fire WARNING per call. Grep recipe: ``rg 'lsp\\['``.
agent/lsp/manager.py: wire the eventlog into _get_or_spawn and
get_diagnostics_sync so users can answer "did LSP fire on this edit?"
with a single grep, plus surface "binary not on PATH" warnings once
instead of silently retrying every write.
tools/file_operations.py: backend-type gate. ``_lsp_local_only()``
returns False for non-local backends (Docker / Modal / SSH /
Daytona); ``_snapshot_lsp_baseline`` and ``_maybe_lsp_diagnostics``
now skip entirely on remote envs. The host-side language server
can't see files inside a sandbox, so this prevents pretending to
lint a file the host process can't open.
agent/lsp/protocol.py: 8 KiB cap on the header block in
``read_message``. A pathological server that streams headers
without ever emitting CRLF-CRLF would have looped forever consuming
bytes; now raises ``LSPProtocolError`` instead.
agent/lsp/workspace.py: 64-step cap on ``find_git_worktree`` and
``nearest_root`` upward walks, plus try/except containment around
``Path(...).resolve()`` and child ``.exists()`` calls. Defensive
against pathological inputs (symlink loops, encoding errors,
permission failures mid-walk) — the lint hook is hot-path code and
must never raise.
Tests:
- tests/agent/lsp/test_eventlog.py: 18 tests covering steady-state
silence (clean writes stay DEBUG), state-transition INFO-once
semantics (active for, no project root), action-required
WARNING-once (server unavailable), per-call WARNING (timeouts,
spawn failures), and the "1000 clean writes => 1 INFO" contract.
- tests/agent/lsp/test_backend_gate.py: 5 tests verifying
_lsp_local_only / snapshot_baseline / maybe_lsp_diagnostics skip
the LSP layer for non-local backends and route correctly for
LocalEnvironment.
- tests/agent/lsp/test_protocol.py: new test_read_message_rejects_runaway_header
exercising the 8 KiB cap.
Validation:
- 73/73 LSP tests pass (49 original + 18 eventlog + 5 backend-gate + 1 framer cap)
- 198/198 pass when run alongside existing file_operations tests
- Live E2E re-run with pyright still surfaces "ERROR [2:12] Type
... reportReturnType (Pyright)" through the full path, then patch
fix removes it on the next call.
* feat(lsp): atexit cleanup + separate lsp_diagnostics JSON field
Two improvements salvaged from #24414's plugin-form alternative,
keeping our core-integrated design:
1. atexit cleanup of spawned language servers
----------------------------------------------------------------
``agent/lsp/__init__.get_service`` now registers an ``atexit``
handler on first creation that tears down the LSPService on
Python exit. Without this, every ``hermes chat`` exit was
leaking pyright/gopls/etc. processes for a few seconds while
their stdout buffers drained -- they got reaped by the kernel
eventually but a watchful ``ps aux`` would catch them.
The handler runs once per process (gated by
``_atexit_registered``); idempotent ``shutdown_service``
ensures double-fire is a no-op. Errors during shutdown are
swallowed at debug level since by the time atexit fires the
user has already seen the agent's final response.
2. Separate ``lsp_diagnostics`` field on WriteResult / PatchResult
----------------------------------------------------------------
Previously the LSP layer folded its diagnostic block into the
``lint.output`` string, conflating the syntax-check tier with
the semantic tier. The agent (and any downstream parsers) now
read syntax errors and semantic errors as independent signals:
{
"bytes_written": 42,
"lint": {"status": "ok", "output": ""},
"lsp_diagnostics": "<diagnostics file=...>\nERROR [2:12] ..."
}
``_check_lint_delta`` returns to its original two-tier shape
(syntax check + delta filter); ``write_file`` and
``patch_replace`` independently fetch LSP diagnostics via
``_maybe_lsp_diagnostics`` and pass them into the new field.
``patch_replace`` propagates the inner write_file's
``lsp_diagnostics`` so the outer PatchResult carries the patch's
delta correctly.
Tests: 19 new
- tests/agent/lsp/test_lifecycle.py (8 tests): atexit registration
fires once and only once across N get_service calls; the
registered callable is our internal shutdown wrapper;
shutdown_service is idempotent and safe when never started;
exceptions during shutdown are swallowed; inactive service is
cached so we don't rebuild on every check.
- tests/agent/lsp/test_diagnostics_field.py (11 tests): WriteResult
/ PatchResult dataclass shape, to_dict include/omit semantics,
channel separation (lint and lsp_diagnostics carry independent
signals), write_file populates the field via
_maybe_lsp_diagnostics only when the syntax tier is clean,
patch_replace propagates the field forward from its internal
write_file.
Validation:
- 92/92 LSP tests pass (73 prior + 8 lifecycle + 11 diagnostics field)
- 217/217 pass with file_operations + LSP combined
- Live E2E reverified: clean writes -> both fields empty/none; type
error introduced -> lint clean (parses), lsp_diagnostics carries
the pyright reportReturnType block; patch fix -> both fields
clean again.
* fix(lsp): broken-set short-circuit so a wedged server isn't paid every write
Discovered while auditing failure paths: a language server binary that
hangs (sleep forever, no LSP traffic on stdin/stdout) caused EVERY
subsequent write to re-pay the 8s snapshot_baseline timeout. Five
writes = ~64s of dead time.
The bug: ``_get_or_spawn`` adds the (server_id, root) pair to
``_broken`` inside its inner exception handler, but when the OUTER
``_loop.run`` timeout fires, it cancels the inner task before that
handler runs. The pair never makes it to broken-set, so the next
write re-enters the spawn path and re-pays the timeout.
Fix:
- New ``_mark_broken_for_file`` helper at the service layer marks
the (server_id, workspace_root) pair broken from the OUTSIDE when
the outer timeout fires. Called from the except branches in
``snapshot_baseline``, ``get_diagnostics_sync`` (asyncio.TimeoutError
+ generic Exception). Also kills any orphan client process that
survived the cancelled future, fire-and-forget with a 1s ceiling.
- ``enabled_for`` now consults the broken-set BEFORE returning True.
Files in already-broken (server_id, root) pairs short-circuit to
False, so the file_operations layer skips the LSP path entirely
with no spawn cost. Until the service is restarted (``hermes lsp
restart``) or the process exits.
- A single eventlog WARNING is emitted on first mark-broken so the
user knows which server gave up. Subsequent edits in the same
project stay silent.
Tests: 7 new in tests/agent/lsp/test_broken_set.py — covers the
key shape (server_id, per_server_root), enabled_for short-circuit,
sibling-file skip in same project, project isolation (broken in
A doesn't affect B), graceful no-op for missing-server / no-workspace,
and an end-to-end test that snapshots after a failure and verifies
the next ``enabled_for`` returns False.
Validation:
- Live retest of the wedged-binary scenario: 5 sequential writes,
first 8.88s (the one snapshot timeout), subsequent four ~0.84s
(no LSP cost). Down from 5x12.85s = 64s before this fix.
- 99/99 LSP tests pass (92 prior + 7 broken-set)
- 224/224 pass with file_operations + LSP combined
- Happy path E2E reverified — clean write, type error introduced,
patch fix all behave correctly with the new broken-set logic.
Note: the FIRST write to a wedged binary still pays 8s (the
snapshot_baseline timeout). We could shorten that, but pyright/
tsserver normally take 2-3s and slow CI rust-analyzer can need
5+ seconds, so 8s is the conservative ceiling. Subsequent writes
are instant.
Daytona ships breaking SDK changes on June 10, 2026 — `list()` returns
an iterator and the `page=` offset parameter is removed. We pin
daytona==0.155.0 so we're past the May 24 hard-cutoff, but the
legacy-sandbox resume path in DaytonaEnvironment still passes `page=1`
and reads `.items` off the result.
Switch to `next(iter(results), None)` against a single-result
`list(labels=..., limit=1)` call. Update tests to use `iter([...])`
and drop the `page=1` kwarg from list() assertions.
Allow integrations to share a visible Camofox identity with Hermes and recover existing tabs without carrying local patches.

* fix(install): use `--extra all` not `--all-extras`; drop lazy-covered extras from [all]
Two coupled fixes for the Windows install hang where uv sync built
python-olm from sdist and failed on missing make.
# Root cause: --all-extras vs --extra all (credit: ethernet)
`uv sync --all-extras` installs every key in [project.optional-
dependencies], bypassing the curated [all] extra entirely. So even
when [all] excluded [matrix], [rl], [yc-bench], etc., the installer
pulled them anyway because they were still defined as extras. On
Windows that meant python-olm (no wheel, needs make to build from
sdist) and the install died there.
The right flag is `--extra all` — install just the [all] extra's
contents, respecting curation. Empirically verified via dry-run:
--all-extras: pulls python-olm, mautrix, ctranslate2, onnxruntime,
atroposlib, tinker, wandb, modal, daytona, vercel,
python-telegram-bot, discord.py, slack-bolt,
dingtalk-stream, lark-oapi, anthropic, boto3,
edge-tts, elevenlabs, exa-py, fal-client, faster-
whisper, firecrawl-py, honcho-ai, parallel-web
--extra all: pulls none of those — just [all]'s curated set
Dockerfile already uses `--extra all` (with comment explaining the
gotcha) — knowledge existed; the gap was install.sh / install.ps1 /
setup-hermes.sh.
Sites fixed: scripts/install.sh L1118, scripts/install.ps1 L809,
setup-hermes.sh L245.
# Companion fix: drop lazy-covered extras from [all]
`tools/lazy_deps.py` already covers anthropic, bedrock, exa,
firecrawl, parallel-web, fal, edge-tts, elevenlabs, modal, daytona,
vercel, all messaging platforms (telegram/discord/slack/matrix/
dingtalk/feishu), honcho, and faster-whisper. They were ALSO in
[all], which defeats the whole point of lazy-install — fresh
installs eager-pulled them and inherited whatever was broken
upstream (the matrix → python-olm → no Windows wheel chain being
the proximate symptom).
[all] now contains only what genuinely can't be lazy-installed:
cron, cli, dev, pty, mcp, homeassistant, sms, acp, google, web,
youtube. Same trim applied to [termux-all]. New regression test
asserts the contract: every extra in LAZY_DEPS must NOT also appear
in [all].
# Companion fix: surface uv progress + errors
setup-hermes.sh's hash-verified path swallowed uv's stderr to a
tempfile, identical to the install.sh bug fixed in PR #24504. Same
fix applied: stream stderr through directly so users see live
progress instead of staring at a frozen prompt.
# Files
- pyproject.toml: trim [all] and [termux-all] to non-lazy extras only.
- scripts/install.sh: --all-extras → --extra all; trim _ALL_EXTRAS /
_PYPI_EXTRAS to match.
- scripts/install.ps1: --all-extras → --extra all; trim $allExtras /
$pypiExtras to match.
- setup-hermes.sh: --all-extras → --extra all; stream stderr.
- tests/test_project_metadata.py: invert matrix-in-[all] assertion;
add lazy-coverage contract test.
- uv.lock: regenerated.
# Validation
5/5 metadata tests pass. 37/37 in update_autostash + tool_token_
estimation. `uv lock --check` passes. Empirical dry-run confirms
`--extra all` excludes python-olm + RL chain on the new lockfile.
* fix(install): parse [all] from pyproject.toml instead of mirroring it
ethernet's review point: the previous patch left two hand-mirrored
copies of [all]'s contents (in install.sh's $_ALL_EXTRAS and
install.ps1's $allExtras). That guarantees future drift the next
time pyproject.toml's [all] changes.
Now both scripts parse pyproject.toml at install time using stdlib
tomllib (Python 3.11+, which the bootstrap step already requires).
Single source of truth. The only purpose of the parsed list is to
build the 'Tier 2: [all] minus broken extras' fallback spec — so we
parse, filter against $brokenExtras, and rebuild the .[a,b,c] spec.
Also: removed redundant fallback tiers.
Before: Tier 1 [all]
Tier 2 [all] minus broken
Tier 3 PyPI-only extras (no git deps)
Tier 4 [web,mcp,cron,cli,messaging,dev]
Tier 5 .
After: Tier 1 [all]
Tier 2 [all] minus broken
Tier 3 .
Tier 3 (PyPI-only) and Tier 4 (dashboard+core) used to dodge the [rl]
git+sdist deps and the [matrix] python-olm build. Both are no longer
in [all] post-2026-05-12 lazy-install migration, so the carve-out
tiers had no remaining content. Tier 4 also referenced [messaging],
which is now lazy-installed — the hardcoded fallback was actually
inconsistent with the new policy.
Defensive fallback: if tomllib parse fails (corrupted pyproject,
unexpected schema), Tier 2 collapses to '.[all]' (same as Tier 1) so
the broken-extras path becomes a no-op rather than crashing.
* fix(gateway): hide Matrix from setup picker on Windows
Matrix is the one messaging platform that has no working install path
on Windows: [matrix] -> mautrix[encryption] -> python-olm, which has
Linux-only wheels and needs make + libolm to build from sdist. The
[all] cleanup in this PR keeps mautrix out of fresh installs, but a
user who picked Matrix in 'hermes setup gateway' would still walk
into the same sdist build failure when the wizard tried to install
the extra.
Hide the option at the picker so users never get the chance to try.
The gate lives in _all_platforms() — single source of truth for the
setup wizard, the curses gateway-config menu, and any future picker.
Adapter loading at runtime is intentionally NOT gated: users who
already have MATRIX_* env vars set (e.g. config copied from a Linux
install) keep working if they somehow have python-olm available.
This is the lowest-friction fix — picker visibility only.
Tests cover linux/darwin/win32 and verify other platforms aren't
collateral damage.
Post-#21561 the liveness probe in acquire_scoped_lock() routes through
gateway.status._pid_exists (psutil-first, safe on Windows), not
os.kill(pid, 0). The two new macOS regression tests were patching
status.os.kill, which had no effect — the unmocked psutil call returned
False for PID 99999, marking the lock stale before the new code branch
ran. The 'replaces' test passed only because acquired=True was already
the expected outcome; the 'keeps' test failed in CI.
Switch both tests to monkeypatch status._pid_exists directly, matching
the existing test_acquire_scoped_lock_rejects_live_other_process pattern,
so they actually exercise the new start_time=None + cmdline-based
staleness branch.
On macOS (and Windows), /proc is unavailable so _get_process_start_time()
always returns None. When a gateway creates a scoped lock record with
start_time=None and then exits, macOS can reuse that PID for an unrelated
process. On restart, acquire_scoped_lock() sees:
1. os.kill(pid, 0) succeeds (PID is alive — but it's bluetoothuserd, not
the gateway)
2. existing.start_time is None and current_start is None, so the
start_time comparison is inconclusive
3. The lock is treated as active, blocking gateway startup with:
"Telegram bot token already in use (PID 873). Stop the other gateway
first."
Root cause: _read_process_cmdline() only reads /proc/<pid>/cmdline, which
doesn't exist on macOS. It always returns None, making
_looks_like_gateway_process() always return False, so the cmdline fallback
path in acquire_scoped_lock() was unreachable on macOS.
Fix (two parts):
1. _read_process_cmdline(): Add a ps(1) fallback for platforms without
/proc. When /proc/<pid>/cmdline doesn't exist, we now run
"ps -p <pid> -o command=" to retrieve the process command line. The
/proc path is tried first (preserving Linux performance); ps is only
invoked as a fallback.
2. acquire_scoped_lock(): When both the lock record's start_time and the
live process's start_time are None (the macOS case), fall back to
checking whether the live PID still looks like a Hermes gateway process
via _looks_like_gateway_process(). If it doesn't, the lock is stale.
Closes#16376
Detect when write_file / patch calls fail during a turn and are never
superseded by a successful write to the same path. When the final
text response is delivered, append an advisory footer listing the
files that did NOT change — so models that over-claim 'patched 5 files'
after 4 silent failures can't hide the lie.
Catches the failure mode reported in Ben Eng's llm-wiki session:
grok-4.1-fast issued batches of parallel patches, half failed with
'Could not find old_string', and the agent summarised the turn
claiming every file was edited. The user had to manually run
'git status' each turn to catch it.
The verifier is a pure post-hoc check on tool results — no new LLM
calls, no synthetic messages injected into history (prompt cache
preserved), no changes to tool argument dispatch. Per-turn state is
keyed by path; a later successful write to the same path clears the
failure entry so single-file retry recovery is not flagged.
Wired into both _execute_tool_calls_concurrent and
_execute_tool_calls_sequential, so batched parallel patches and one-at-
a-time edits are both covered. Footer emission happens after the
agent loop exits, before transform_llm_output / post_llm_call plugin
hooks run, so plugins still see (and can modify) the augmented text.
Config: display.file_mutation_verifier (bool, default true) +
HERMES_FILE_MUTATION_VERIFIER env override.
31 unit tests in tests/run_agent/test_file_mutation_verifier.py cover
target extraction (write_file, patch-replace, patch-v4a single and
multi-file), error-preview extraction (JSON .error field and plain
string), per-turn state transitions (first-error-wins on repeated
failure, success supersedes failure), footer rendering (truncation
at 10 entries, user-actionable hint), and env/config precedence.

* feat(security): supply-chain advisory checker + lazy-install framework + tiered install fallback
Three coordinated mitigations for the Mini Shai-Hulud worm hitting
mistralai 2.4.6 on PyPI (2026-05-12) and for the next single-package
compromise that follows.
# What this PR makes true
1. Users with the poisoned mistralai 2.4.6 in their venv get a loud
detection banner with copy-pasteable remediation steps the moment
they run hermes (and on every gateway startup).
2. One quarantined / yanked PyPI package can no longer silently demote
a fresh install to 'core only' — the installer keeps every other
extra and tells the user which tier landed.
3. Future opt-in backends (Mistral, ElevenLabs, Honcho, etc.) can
lazy-install on first use under a strict allowlist, instead of
eagerly pulling everything at install time.
# Detection: hermes_cli/security_advisories.py
- ADVISORIES catalog (one entry currently: shai-hulud-2026-05 for
mistralai==2.4.6). Adding the next one is a single dataclass.
- detect_compromised() uses importlib.metadata.version() — no pip
dependency, works in uv venvs that lack pip.
- Banner cache (~/.hermes/cache/advisory_banner_seen) rate-limits
the startup banner to once per 24h per advisory.
- Acks persisted to security.acked_advisories in config.yaml; never
re-banner after ack.
- Wired into:
* hermes doctor — runs first, prints full remediation block
* hermes doctor --ack <id> — dismisses an advisory
* cli.py interactive run() and single-query branches — short
stderr banner pointing at hermes doctor
* gateway/run.py startup — operator-visible warning in gateway.log
# Lazy-install framework: tools/lazy_deps.py
- LAZY_DEPS allowlist maps namespaced feature keys (tts.elevenlabs,
memory.honcho, provider.bedrock, etc.) to pip specs.
- ensure(feature) installs missing deps in the active venv via the
uv → pip → ensurepip ladder (matches tools_config._pip_install).
- Strict spec safety regex rejects URLs, file paths, shell metas,
pip flag injection, control chars — only PyPI-by-name accepted.
- Gated on security.allow_lazy_installs (default true) plus the
HERMES_DISABLE_LAZY_INSTALLS env var for restricted/audited envs.
- Migrated three backends as proof of pattern:
* tools/tts_tool.py — _import_elevenlabs() calls ensure first
* plugins/memory/honcho/client.py — get_honcho_client lazy-installs
* tts.mistral / stt.mistral entries pre-registered for when PyPI
restores mistralai
# Installer fallback tiers
scripts/install.sh, scripts/install.ps1, setup-hermes.sh:
- Centralised _BROKEN_EXTRAS list (currently: mistral). Edit one
array when a transitive breaks; users keep every other extra.
- New 'all minus known-broken' tier between [all] and the existing
PyPI-only-extras tier. Only kicks in when [all] fails resolve.
- All three tiers explicit: every fallback announces which tier
landed and prints a re-run hint when not on Tier 1.
- install.ps1 and install.sh both regenerate their tier specs from
the same _BROKEN_EXTRAS array so updates stay in sync.
Side effect: install.ps1 Tier 2 spec previously hardcoded 'mistral'
in its extra list — bug fixed by the refactor (mistral is filtered
out).
# Config
hermes_cli/config.py — DEFAULT_CONFIG.security gains:
- acked_advisories: [] (advisory IDs the user has dismissed)
- allow_lazy_installs: True (security gate for ensure())
No config version bump needed — both keys nest under existing
security: block, and load_config's deep-merge picks up DEFAULT_CONFIG
defaults for users with older configs.
# Tests
tests/hermes_cli/test_security_advisories.py — 23 tests covering:
- detect_compromised matches/non-matches, wildcard frozenset
- ack persistence, idempotence, blank rejection, config-failure path
- banner cache rate limiting + 24h re-banner + ack-stops-banner
- short_banner_lines / full_remediation_text / render_doctor_section /
gateway_log_message
- shipped catalog well-formedness invariant
tests/tools/test_lazy_deps.py — 40 tests covering:
- spec safety: 11 safe parametrized + 18 unsafe parametrized
- allowlist: unknown-feature rejection, namespace.name shape,
every shipped spec passes the safety regex
- security gating: config flag, env var, default, fail-open
- ensure() happy/sad paths: already-satisfied, install success,
pip stderr surfaced on failure, install-succeeds-but-still-missing
- is_available, feature_install_command
Combined: 63 new tests, all passing under scripts/run_tests.sh.

* build(deps): pin every direct dep to ==X.Y.Z (no ranges)
Companion to the supply-chain advisory work: replace every >=/</~= range
in pyproject.toml's [project.dependencies] and [project.optional-dependencies]
with an exact ==X.Y.Z pin sourced from uv.lock.
Why: ranges allow PyPI to ship a fresh version of any direct dep at any
time without a code review on our side. With ranges, the malicious
mistralai 2.4.6 release would have been pulled by every fresh
'pip install -e .[all]' for the hours between upload and PyPI's
quarantine — exactly the install window we got hit on. Exact pins close
that window: the only way a new package version reaches a user is via
an intentional update on our end.
What the user-facing change is: nothing, behavior-wise. Every package
resolves to the same version it was already resolving to via uv.lock —
the pins just remove the resolver's freedom to pick a different one.
Cost: any user installing Hermes alongside another package that requires
a newer pin gets a resolver conflict. Acceptable for our isolated-venv
install path; documented in the new comment block.
Build-system requires line (setuptools>=61.0) is intentionally left
as a range — pinning the build backend would block fresh pip from
bootstrapping the build on architectures where that exact wheel isn't
available.
mistral extra (mistralai==2.3.0) is pinned but stays out of [all]
(per PR #24205). 'uv lock' regeneration will fail until PyPI restores
mistralai; lockfile regeneration is gated behind that, NOT on every PR.
LAZY_DEPS in tools/lazy_deps.py also moved to exact pins so the lazy-
install pathway can never resolve a different version than the one
declared in pyproject.toml.
Validation:
- Cross-checked all 77 pinned direct deps in pyproject.toml against
uv.lock — every pin matches the resolved version exactly.
- Cross-checked all LAZY_DEPS specs against uv.lock — same.
- 'uv pip install -e .[all] --dry-run' resolves 205 packages cleanly.
- tests/tools/test_lazy_deps.py + tests/hermes_cli/test_security_advisories.py
→ 63/63 passing (every shipped spec passes the safety regex).
- Doctor + TTS + transcription targeted suite → 146/146 passing.
* build(deps): hash-verify transitives via uv.lock; remove unresolvable [mistral] extra
You asked: 'what about the dependencies the dependencies rely on?' —
correctly noting that exact-pinning direct deps in pyproject.toml does
NOT cover the transitive graph. `pip install` and `uv pip install` both
re-resolve transitives fresh from PyPI at install time, so a compromised
transitive (e.g. `httpcore` if it got worm-poisoned tomorrow) would
still hit our users even with every direct dep exact-pinned.
# What this commit fixes
1. **Both real installer scripts now prefer `uv sync --locked` as Tier 0.**
uv.lock records SHA256 hashes for every transitive — a compromised
package with a different hash gets REJECTED. Falls through to the
existing `uv pip install` cascade if the lockfile is missing or
stale, with a loud warning that the fallback path does NOT
hash-verify transitives. Previously only `setup-hermes.sh` (the dev
path) used the lockfile; `scripts/install.sh` and `scripts/install.ps1`
(the paths fresh users actually run) skipped it.
2. **Removed the `[mistral]` extra entirely.** The `mistralai` PyPI
project is fully quarantined right now — every version returns 404,
so any pin we wrote was unresolvable, which broke `uv lock --check`
in CI. Restoration is documented in pyproject.toml as a 5-step
checklist (verify, re-add extra, re-enable in 4 modules, regenerate
lock, optionally re-add to [all]).
3. **Regenerated uv.lock.** 262 packages, mistralai/eval-type-backport/
jsonpath-python pruned. `uv lock --check` now passes.
# Defense-in-depth view
| Layer | Where | Protects against |
|----------------------------|-------------------|-------------------------------------------|
| Exact pins in pyproject | direct deps | new mistralai 2.4.6-style direct compromise |
| uv.lock + `--locked` install | transitive graph | transitive worm injection |
| Tier-0 hash-verified path | install.sh / .ps1 | actually USE the lockfile in fresh installs |
| `uv lock --check` CI gate | every PR | drift between pyproject and lockfile |
| `hermes_cli/security_advisories.py` | runtime | cleanup for users who already got hit |
The exact pinning + hash verification together close the supply-chain
gap. Without the lockfile path, exact pins alone are theater.
# Validation
- `uv lock --check` → passes (262 packages resolved, no drift).
- `bash -n` on install.sh + setup-hermes.sh → OK.
- 209/209 tests passing across new + adjacent test files
(test_lazy_deps.py, test_security_advisories.py, test_doctor.py,
test_tts_mistral.py, test_transcription_tools.py).
- TOML parse OK.
* chore: remove community announcement drafts (PR body covers it)
* build(deps): lazy-install every opt-in backend (anthropic, search, terminal, platforms, dashboard)
Extends the lazy-install framework to cover everything that's not used by
every hermes session. Base install drops from ~60 packages to 45.
Moved out of core dependencies = []:
- anthropic (only when provider=anthropic native, not via aggregators)
- exa-py, firecrawl-py, parallel-web (search backends; only when picked)
- fal-client (image gen; only when picked)
- edge-tts (default TTS but still optional)
New extras in pyproject.toml: [anthropic] [exa] [firecrawl] [parallel-web]
[fal] [edge-tts]. All added to [all].
New LAZY_DEPS entries: provider.anthropic, search.{exa,firecrawl,parallel},
tts.edge, image.fal, memory.hindsight, platform.{telegram,discord,matrix},
terminal.{modal,daytona,vercel}, tool.dashboard.
Each import site now calls ensure() before importing the SDK. Where the
module had a top-level try/except (telegram, discord, fastapi), the
graceful-fallback pattern was extended to lazy-install on first
check_*_requirements() call and re-bind module globals.
Updated test_windows_native_support.py tzdata check from snapshot
(>=2023.3 literal) to invariant (any version + win32 marker).
Validation:
- Base install: 45 packages (was ~60); 6 newly-extracted packages absent
- uv lock --check: passes (262 packages, no drift)
- 209/209 lazy_deps + advisory + doctor + tts/transcription tests passing
- py_compile clean on all 12 modified modules
The `mistralai` PyPI package was quarantined on 2026-05-12 after a
malicious 2.4.6 release. Every fresh resolve (AUR makepkg, Docker build,
CI run, install.sh first-run) currently fails on
`mistralai>=2.3.0,<3` because PyPI returns zero candidates.
Existing users running `hermes update` mostly didn't notice — `hermes
update` falls back from `.[all]` to per-extra retries and silently
skips mistral with a warning that scrolls past. But fresh installs
hard-fail or lose every other extra.
Changes:
- pyproject.toml: drop `hermes-agent[mistral]` from `[all]` and
`[termux-all]`. The `mistral` extra itself is preserved so users
can opt back in once PyPI un-quarantines.
- hermes_cli/tools_config.py: hide Mistral Voxtral TTS from the
`hermes tools` provider picker until restored.
- hermes_cli/web_server.py: drop "mistral" from dashboard STT options.
- tools/transcription_tools.py: explicit `provider: mistral` returns
"none" with a clear status message; auto-detect skips mistral.
- tools/tts_tool.py: dispatcher returns a clear "temporarily disabled"
error before any SDK import attempt (avoids cached-stale-package
surprises).
- tests/tools/: update three test files to assert the new disabled
behavior. Each test docstring records why and points at the rollback
trigger (PyPI un-quarantines mistralai).
Restore plan: revert this commit once the package is available on PyPI
again. The behavior change is intentional and documented in code
comments + test docstrings to make the rollback trivial.
Validation:
- scripts/run_tests.sh tests/tools/ -k 'mistral or stt or tts' →
425/425 passing.

Qwen models on Nous Portal (e.g. qwen3.6-plus) now get the same envelope-layout
cache_control markers and long-lived (1h cross-session) cache treatment as
Portal Claude. Portal proxies to OpenRouter with identical wire-format and
cache_control semantics, but the prior policy left Portal Qwen falling through
to the alibaba-family branch (which only matches provider=opencode/alibaba),
serving 0% cache hits and re-billing the full prompt every turn.
Scope is narrow: Portal Claude OR Portal Qwen. Other models on Portal keep
their existing behavior.
- _anthropic_prompt_cache_policy: add (is_nous_portal and qwen) -> (True, False)
- _supports_long_lived_anthropic_cache: drop Claude-only gate for Portal so
Qwen also gets the validated 1h cross-session layout
- tests cover both functions, both bare and vendored qwen slug forms, and
the rejection of non-Claude non-Qwen Portal traffic
Free-tier users were seeing 'No free models currently available.' in the
`hermes model` and post-login pickers even though qwen/qwen3.6-plus is
free on the Portal right now. Three independent breakages compounded:
1. The docs-hosted catalog manifest at website/static/api/model-catalog.json
was not regenerated when _PROVIDER_MODELS['nous'] was updated, so users
fetching the manifest got a list that didn't include qwen/qwen3.6-plus.
2. _resolve_nous_pricing_credentials() returned ('', '') on any auth blip,
collapsing get_pricing_for_provider('nous') to {} and making every
curated model fall through the free-tier filter as 'paid'.
3. Even with healthy pricing, the picker only ever showed models from the
in-repo curated list intersected with live pricing — a Portal-flagged
free model not yet in the curated list could never appear.
Changes:
- hermes_cli/models.py: new union_with_portal_free_recommendations() that
augments the curated list with Portal freeRecommendedModels entries
(with synthetic free pricing so partition keeps them). The Portal's
/api/nous/recommended-models endpoint is now the source of truth for
free-tier surfacing — old Hermes builds will see new free models
without a CLI release.
- hermes_cli/models.py: _resolve_nous_pricing_credentials() falls back to
the public inference base URL when runtime cred resolution fails.
The /v1/models endpoint exposes pricing without auth, so silently
returning {} just because a refresh token expired was wrong.
- hermes_cli/auth.py + hermes_cli/main.py: both free-tier picker call
sites call union_with_portal_free_recommendations() before partition.
- tests/hermes_cli/test_models.py: 7 tests covering union behaviour
(prepend, dedup, end-to-end with stale pricing, empty/missing/error
payloads, invalid entries).
- tests/hermes_cli/test_model_catalog.py: drift guard
TestManifestMatchesInRepoLists fails CI when _PROVIDER_MODELS['nous']
or OPENROUTER_MODELS is edited without re-running
scripts/build_model_catalog.py. Verified empirically that removing a
manifest entry triggers an assertion with an actionable error message.
Validation:
- 133/133 targeted tests pass (test_models, test_model_catalog,
test_auth_nous_provider).
- Live E2E against the real Portal:
- Stale curated list ['claude-opus','claude-sonnet','gpt-5.4'] (no
qwen) → after union: ['qwen/qwen3.6-plus', ...] →
partition(free_tier=True): selectable=['qwen/qwen3.6-plus'].
- Simulated expired refresh token → anon fetch returns 403 pricing
entries including qwen/qwen3.6-plus -> {prompt:0, completion:0}.
- ruff: clean.
cua-driver was only installed once on toolset enable: `_run_post_setup` early-returns when the binary is already on PATH, so upstream fixes (e.g. v0.1.6 Safari window-focus fix) never reached existing users without manual reinstall.
Two refresh points now:
- `hermes update` re-runs the upstream installer at the end of the update if cua-driver is on PATH (macOS-only, no-op otherwise). Ties driver freshness to the user-controlled update cadence — no startup latency, no per-launch GitHub API call.
- `hermes computer-use install --upgrade` for manual force-refresh.
The upstream `install.sh` always pulls the latest release, so re-running is the canonical upgrade path. No version-comparison logic needed.
`hermes computer-use status` now shows the installed version, and points at `--upgrade` for refreshing.
Fixes#22832.
## Root cause
`hermes_cli/web_server.py:start_oauth_login` dispatched OAuth flows by
the catalog's `flow` field rather than provider id:
if catalog_entry["flow"] == "pkce":
return _start_anthropic_pkce()
The catalog had two `flow: "pkce"` entries — `anthropic` and
`minimax-oauth` — so clicking "Login" on MiniMax in the dashboard's
Keys tab unconditionally launched the Anthropic/Claude PKCE flow.
## Fix
Three changes in `hermes_cli/web_server.py`:
1. Catalog entry for `minimax-oauth` changed from `flow: "pkce"` to
`flow: "device_code"`. From a UX perspective MiniMax is a
verification-URI + user-code flow (open URL, enter code, backend
polls) — same shape as Nous's device-code flow. The PKCE bit
(verifier + challenge from `_minimax_pkce_pair`) is a security
extension that doesn't change the operator experience; the existing
dashboard modal already renders `device_code` correctly for this UX.
2. New MiniMax branch in `_start_device_code_flow`, mirroring the
existing Nous branch but calling MiniMax-specific helpers
(`_minimax_request_user_code`, `_minimax_pkce_pair`). Stashes
verifier + state in the session for the poller to consume. Handles
the overloaded `expired_in` field (could be unix-ms timestamp OR
seconds-from-now duration) the same way `_minimax_poll_token` does.
3. New `_minimax_poller` background thread mirroring `_nous_poller`.
Calls `_minimax_poll_token` → on success builds the same
`auth_state` dict the CLI flow (`_minimax_oauth_login`) builds, and
persists via `_minimax_save_auth_state` so the dashboard path leaves
the system in the same state as `hermes auth add minimax-oauth`.
Plus a dispatcher tightening to prevent regression: the `pkce` branch
now requires `provider_id == "anthropic"`, so any future PKCE provider
added without a proper start function gets a clean
`400 Unsupported flow` rather than silently launching Anthropic OAuth.
## Test
New `tests/hermes_cli/test_web_oauth_dispatch.py`:
- Regression test asserting MiniMax start does NOT return claude.ai
- Sanity test that Anthropic PKCE still works after the dispatcher
tightening
- Forward-looking test: a hypothetical pkce-flagged provider without
an explicit branch is rejected cleanly rather than misrouted
## Limitations
- The dashboard MiniMax path defaults to `region="global"`. CN-region
operators can still use the CLI flow which supports `--region cn`.
Adding a region toggle to the dashboard UI is a follow-up.
Follow-up to #23863 (CJK table alignment). The realigner was
correctly padding pipes to identical column offsets, but when a
table's natural width exceeds terminal cells it produced lines that
the terminal soft-wrapped mid-cell, destroying column alignment
visually even though the bytes were perfectly padded. Reported as
'columns are not aligned' on tables containing one long row alongside
several short rows.
Approach mirrors Claude Code's MarkdownTable.tsx narrow-terminal
fallback: when realign_markdown_tables is given an available_width
budget and the rebuilt horizontal table exceeds it, render each body
row as 'Header: value' lines separated by a thin ─ rule. Word-wraps
oversize values at the budget with a 2-space continuation indent.
- agent/markdown_tables.py: realign_markdown_tables(text, available_width=None);
threshold check at the top of _render_block flips into a new
_render_vertical fallback. Includes _wrap_to_width with hard-break
for tokens longer than the budget.
- cli.py: helper _terminal_width_for_streaming() returns
shutil.get_terminal_size().columns minus _STREAM_PAD and a 2-cell
safety margin; passed to all three realign call sites
(_render_final_assistant_content for strip+render Panel paths, and
the streaming flushers in _emit_stream_text / _flush_stream).
- tests/agent/test_markdown_tables.py: 4 new tests covering the
overflow-vertical fallback for ASCII + CJK content, the
'fits → keep horizontal' case, and the long-cell wrap with indent.
Live-verified: with COLUMNS=100, the user's reported 'long row in
ASCII table' case now renders as vertical key-value rows that all fit
the panel; the 6-column CJK comparison table still renders as an
aligned horizontal table because it fits inside 100 cols.
The old mtime-tracking staleness machinery (_tui_build_needed,
_hermes_ink_bundle_stale, _find_bundled_tui) tried to avoid rebuilding
by comparing source timestamps to dist/entry.js. This was fragile and
added ~100 lines of code. Replace with three clear paths:
1. HERMES_TUI_DIR set (prebuilt/nix): just node dist/entry.js, no build
2. --dev mode: tsx src/entry.tsx, no build, hot reload
3. Normal: always npm run build (esbuild is ~1s, correctness > caching)
Also error when HERMES_TUI_DIR is set with --dev (footgun: prebuilt
bundle has no source code to hot-reload).
Set HERMES_SESSION_ID using the existing session_context.py ContextVar
system for concurrency safety (multiple gateway sessions in one process
won't cross-talk). Also writes os.environ as fallback for CLI mode.
Touchpoints:
- gateway/session_context.py: Add _SESSION_ID ContextVar + _VAR_MAP entry
- run_agent.py: Set both ContextVar and os.environ at init and on
context-compression rotation
- tools/environments/local.py: Bridge ContextVars into subprocess env
in _make_run_env() (ContextVars don't propagate to child processes)
- tests/run_agent/test_session_id_env.py: 3 tests covering env, provided
ID, and ContextVar paths
execute_code subprocess already passes HERMES_* prefixed vars through
_scrub_child_env (line 82: _SAFE_ENV_PREFIXES includes 'HERMES_').
Primary use case: webhook-triggered agents that need to include a
`--resume <session_id>` takeover command in their output.
Cuts input cost for first-turn Claude requests by ~85-90% on subsequent
sessions within an hour. Tools array (~13k tokens for default toolset) +
stable system prefix (~5-8k tokens) get a 1h cache_control marker; the
volatile suffix (memory, USER profile, timestamp, session id) sits in a
separate non-cached block at the end so it doesn't poison the cross-session
prefix when it changes.
Provider gate: Claude on native Anthropic (incl. OAuth subscription),
OpenRouter, and Nous Portal (which proxies to OpenRouter). All other
providers keep today's system_and_3 layout unchanged.
Layout (4 cache_control breakpoints, Anthropic max):
1. tools[-1] -> 1h (cross-session)
2. system content[0] -> 1h (cross-session, stable prefix)
3. messages[-2] -> 5m (within-session rolling)
4. messages[-1] -> 5m (within-session rolling)
Within-session rolling shrinks from 3 messages to 2 to free the breakpoint
budget. On Claude with realistic tool loadouts the long-lived tier carries
the bulk of cross-session value anyway.
System prompt is now always assembled cache-friendly: stable identity /
guidance / skills / platform hints first, then session-stable context
files (AGENTS.md, .cursorrules), then per-call volatile content. Old
single-string callers see the same logical content (same join order),
just reordered so volatile lives at the end.
Config knobs (defaults shown):
prompt_caching:
cache_ttl: "5m" # rolling-window TTL (unchanged)
long_lived_prefix: true # opt-out switch
long_lived_ttl: "1h" # cross-session prefix TTL
Live E2E (tests/agent/test_prompt_caching_live.py, gated on
OPENROUTER_API_KEY) on anthropic/claude-haiku-4.5 with default toolset:
Call 1 (cold): cache_write=13,415 cache_read=0
Call 2 (NEW agent + msg): cache_write=391 cache_read=13,025
Cross-session reuse: 97.09%
Implementation:
* agent/prompt_caching.py: new apply_anthropic_cache_control_long_lived()
+ mark_tools_for_long_lived_cache(); existing apply_anthropic_cache_control()
preserved verbatim for the fallback path.
* agent/anthropic_adapter.py: convert_tools_to_anthropic() now forwards
cache_control onto each Anthropic-format tool dict.
* run_agent.py: _build_system_prompt_parts() returns the 3-tier dict;
_build_system_prompt() joins them (backward compatible).
_supports_long_lived_anthropic_cache() policy added next to the existing
_anthropic_prompt_cache_policy() (which now also recognises Nous Portal
Claude — pre-existing gap fixed in passing).
_build_api_kwargs() resolves tools_for_api once and propagates the
marker through all four build paths (anthropic_messages, bedrock,
codex_responses, profile/legacy chat completions).
Long-lived flag plumbed into the runtime snapshot/restore + model-switch
+ fallback-promotion paths.
Tests:
* tests/agent/test_prompt_caching.py: +8 tests (TestMarkToolsForLongLivedCache,
TestApplyAnthropicCacheControlLongLived).
* tests/run_agent/test_anthropic_prompt_cache_policy.py: +9 tests
(TestSupportsLongLivedAnthropicCache matrix across 8 endpoint classes
+ a fallback-target case).
* tests/agent/test_prompt_caching_live.py: new live E2E (skipif when
OPENROUTER_API_KEY is unset; runs outside the hermetic suite).
* Targeted suites: 327/327 pass (caching/adapter/policy/builder).
* tests/agent/ + tests/run_agent/: 3992 pass, 17 skip, 1 pre-existing
flake (test_async_httpx_del_neuter::test_same_key_replaces_stale_loop_entry,
verified failing on pristine origin/main).
#23482 fixed cache poisoning in the sync path: when a Codex auxiliary
timeout closes the underlying OpenAI client, _evict_cached_client_instance
walks CodexAuxiliaryClient wrappers via their _real_client attribute and
drops the cache entry so the next aux call rebuilds.
The cache key includes async_mode (see _client_cache_key), so the sync and
async clients for the same provider live in two distinct entries pointing
at the same underlying transport. The fix walked the sync wrapper's
_real_client correctly but the async wrappers
(AsyncCodexAuxiliaryClient, AsyncAnthropicAuxiliaryClient,
AsyncGeminiNativeClient) never exposed _real_client at all, so the async
entry survived eviction and kept handing out the poisoned client.
Effect on async aux callers: one timeout now poisons every subsequent
async aux call (compression, vision, session_search, title_generation)
with 'Connection error' until gateway restart -- even while the sync
route recovered as designed in #23482.
Mirror the sync wrapper's _real_client onto each async wrapper so the
existing eviction helper finds them. Three changes, one per wrapper:
- AsyncCodexAuxiliaryClient: self._real_client = sync_wrapper._real_client
(the underlying OpenAI client)
- AsyncAnthropicAuxiliaryClient: same shape
- AsyncGeminiNativeClient: self._real_client = sync_client (Gemini's
native facade is itself the leaf; no OpenAI client beneath it)
Update _evict_cached_client_instance docstring to reflect that it now
covers both sync and async wrappers via the same attribute walk.
Test: TestAuxiliaryClientPoisonedCacheEviction.test_evict_cached_client_instance_walks_async_wrapper
seeds both sync and async cache entries pointing at the same leaf and
asserts both are dropped on a single eviction call. Verified the test
fails without the wrapper changes ("async cache entry survived
eviction -- wrapper is missing _real_client") and passes with them.
Refs #23482, #23432
CJK and emoji glyphs render as two terminal cells but JS String#length
and the model's own padding count them as one, so any markdown table
with Chinese / Japanese / Korean cells drifts right per row when a
real terminal renders it. Both surfaces fix this with a display-cell
width measurement (wcswidth on the Python side, stringWidth on the
TUI side).
Changes:
- agent/markdown_tables.py: new helper. realign_markdown_tables(text)
detects markdown table blocks (header + |---| divider) and
rewrites the row padding using wcwidth.wcswidth so every pipe and
dash lines up across rows. No-op on text without tables.
- cli.py: hook the helper into _render_final_assistant_content for
strip / render modes (raw passes through untouched), and into the
streaming line emitter so live token-by-token rendering also
produces aligned tables. A small two-buffer state machine in
_emit_stream_text holds table rows until the block ends, then
flushes them through the realigner so all rows pad to a single
per-column width.
- ui-tui/src/components/markdown.tsx: renderTable now uses
stringWidth (Bun.stringWidth fast path + East-Asian-width-aware
fallback, already memoised in @hermes/ink) instead of UTF-16
String#length for both column-width measurement and per-cell
padding. Drops the comment that documented the bug as a deliberate
limitation.
Validation:
- New tests/agent/test_markdown_tables.py (11): every rebuilt block
shares pipe column offsets across rows for pure CJK, mixed
CJK+emoji, ragged-row, and multi-table inputs.
- Updated tests/cli/test_cli_markdown_rendering.py: the existing
strip-mode test asserted exact whitespace; rewritten to assert the
alignment contract (cell content survives + every rendered row
shares pipe offsets).
- New ui-tui markdown.test.ts case (1): rendered column-2 start
offset is identical for the header + every body row, including
the CJK row that drifted before the fix.
- Live: hermes chat -q with the user-reported screenshot prompt now
produces a perfectly aligned table on the wire (header, divider,
4 body rows including '通义千问', all pipes at identical columns).
The /model picker for Nous Portal users was returning the in-repo
_PROVIDER_MODELS["nous"] snapshot — which only updates on Hermes
releases — instead of the remote manifest published at
https://hermes-agent.nousresearch.com/docs/api/model-catalog.json.
OpenRouter already pulled from the manifest via fetch_openrouter_models;
"nous" was the only curated provider where the existing manifest
plumbing (get_curated_nous_model_ids → get_curated_nous_models) was
defined but not wired into the picker pipeline. Switch the curated
build in list_authenticated_providers to use it, with the same
graceful fallback to the in-repo snapshot when the manifest is
unreachable.
Test: tests/hermes_cli/test_model_catalog.py exercises the picker with
a patched manifest and asserts the manifest's nous list reaches
list_picker_providers. Falls-back-to-static path was already covered
by test_curated_nous_ids_falls_back_to_hardcoded_on_empty_catalog.
Follow-up to PR #23824. Adds two correctness fixes on top of the
contributor's salvaged commit:
1. Stale-dist fallback no longer gated on `fatal=False`. `cmd_dashboard`
passes `fatal=True` and is the primary scenario this fallback is for
(issue #23817 — Windows Scheduled Task at logon). The previous gate
meant the fallback never fired in the case it was designed for.
2. `--skip-build` now verifies the dist actually exists before starting
the server. Without this, a misconfigured pre-build would launch the
dashboard pointing at a missing dist and silently serve 404s. We now
exit 1 with a clear "pre-build first: cd web && npm run build"
message, and on success print which dist directory is being used.
Verified end-to-end on Linux:
- build fails + stale dist (fatal=True) -> fallback fires
- build fails + no dist (fatal=True) -> exit 1 with stderr surfaced
- build fails + stale dist (fatal=False) -> fallback fires
- --skip-build + missing dist -> exit 1 with clear guidance
- --skip-build + valid dist -> 'Skipping web UI build...'
On Windows systems using a Chinese GBK locale, `hermes update` could misreport the Web UI build as failed even when `npm run build` actually succeeded. The failure was caused by Python decoding captured npm output with the process locale inside a background subprocess reader thread. When npm emitted bytes such as `0x85`, decoding under GBK raised `UnicodeDecodeError`, and Hermes then surfaced a misleading "Web UI build failed" warning.
This change makes the npm install/npm ci path and the Web UI build step decode captured output explicitly as UTF-8 with `errors="replace"`. That keeps unexpected bytes from crashing output collection, preserves successful builds, and prevents false negatives during update on Windows.
The patch also adds regression tests that verify these subprocess calls always use explicit UTF-8 decoding with replacement semantics.
When the user's main provider is openai-codex on the ChatGPT-account
backend (https://chatgpt.com/backend-api/codex), sending a native image
attachment encodes it as data:image/...base64,... in the input_image
field. The OpenAI Responses API on the public endpoint accepts that, but
the ChatGPT-account variant rejects it with HTTP 400:
Invalid 'input[N].content[K].image_url'. Expected a valid URL, but got
a value with an invalid format.
Hermes' image-rejection phrase list didn't include this wording, so the
error escaped the strip-and-retry branch and fell through to the generic
recovery path: model fallback → context-too-large → compression cascade
→ auxiliary OpenRouter 402 spam (issue #23570).
Add a NARROW phrase keyed on the field-path apostrophe used by the Codex
Responses error format: "image_url'. expected". This matches the actual
error format without false-tripping on generic 'Expected a valid URL'
errors from unrelated tools (webhooks, redirect_uri, etc.). Once matched,
the existing branch strips images from history, sets _vision_supported=
False for the session, and retries text-only.
Refs #23570 (1 of 3 image-replay improvements; persistence rewrite to
store image PATHS instead of inlined base64 is a separate follow-up)
