Port from Kilo-Org/kilocode#12508: a stray read-only state.db / -wal /
-shm (sudo run, restored backup, copied dotfiles) previously killed
SessionDB init with an opaque 'sqlite3.OperationalError: attempt to
write a readonly database' raised from deep inside _init_schema —
naming no file and no fix — and the obvious wrong 'fix' (deleting the
-wal) silently loses committed transactions.
New preflight_db_writability() runs before the first connection on both
DB open paths (SessionDB.__init__ and hermes_cli.kanban_db.connect):
- files inside the Hermes home tree are repaired with chmod u+rw (the
safe scope: Hermes owns them, and the OS makes chmod fail on files
the user doesn't own, which bounds the repair exactly);
- anything else (root-owned files, read-only mounts, custom paths)
fails fast with an error naming the exact file and the exact chmod
command, plus an explicit 'do NOT delete the -wal' warning;
- WAL sidecars are never deleted or truncated — once writable, the
normal open path checkpoints committed frames into the DB.
Proven live on main first: chmod 444 state.db -> SessionDB() raises the
opaque readonly error. With the fix: in-home DBs self-heal; out-of-home
DBs get the actionable message. Sabotage run confirms the integration
tests fail without the wiring (2 failed / 10 passed).
Tool-schema assembly at CLI/Desktop startup runs the browser-family
check_fns (browser, browser_cdp, browser_dialog, browser_vision). Each
of those gates called _get_cdp_override(), which resolves the configured
endpoint over HTTP (GET /json/version, timeout=10) — so a *stale*
browser.cdp_url pointing at a dead debug browser cost ~7 serial blocking
socket connects before the banner rendered. Measured on a real Windows
install with a dead http://[::1]:9222 config: 15.1s of an 18s launch,
with no warning or error — just mystery slowness. The value is easy to
leave behind: /browser connect writes a session-scoped env override, but
'hermes config set browser.cdp_url' persists forever while the debug
Chrome it pointed at dies on the next browser restart.
Split the helper:
- _get_cdp_override_raw() — returns the configured value (env var or
config.yaml) with zero network I/O. Used by every is-it-configured
gate: check_browser_requirements, _browser_cdp_check, _is_local_mode,
_is_local_backend, _navigation_session_key, _should_inject_engine
(via _is_local_mode), and the hermes doctor chromium-skip check.
- _get_cdp_override() — unchanged contract (raw + /json/version
resolution), now only called on paths that are about to connect:
session creation and the dialog-supervisor attach.
This follows the existing rule in check_browser_requirements ('do not
execute agent-browser --version here') and the browser.manage status
path, which already banned _get_cdp_override for exactly this reason
(test_browser_manage_status_does_not_call_get_cdp_override): schema
assembly must not perform blocking I/O.
A/B on the same machine, same dead endpoint: get_tool_definitions()
15.08s unpatched -> 1.89s patched, with browser_cdp/browser_dialog
still advertised (gate now keys off configuration, not reachability —
matching the documented lazy-supervisor contract in
_browser_dialog_check).
Adds a regression test asserting the browser_cdp check_fn never touches
the network.
Three code-reuse fixes applied during salvage:
1. Reuse _relative_time from hermes_cli/main.py instead of duplicating
the relative-time formatting logic in hermes_cli/status.py.
2. Extract _stamp_hygiene_compression_provenance helper in gateway/run.py
to deduplicate the two nearly-identical try/except blocks that stamp
compression timeout/abort provenance in the hygiene path.
3. Add ContextCompressor.record_timeout_failure() method and use it from
the in-agent compress_context timeout callback instead of re-implementing
the (60, 300, 900) cooldown ladder inline. The existing summary-LLM
exception handler already has this ladder — now both paths share one
method.
Three mechanisms to detect and notify when gateway sessions stall silently:
1. Mid-turn activity heartbeats stamped to SessionDB so hermes sessions list
and hermes status show progress during long turns without new message rows.
2. Stall watchdog: when a busy session has pending inbound and the shared
activity clock is idle past agent.session_stall_timeout (default 300),
log a WARNING and notify the user once to try /new. Notify-only; does
not kill the turn.
3. Compaction timeout: fenceless compress_context callers get a progress-aware
host budget (compression.context_timeout_seconds default 120 idle,
compression.context_total_ceiling_seconds default 600 ceiling). On timeout,
cancel via commit fence, skip compaction without dropping messages, and
continue the turn.
Closes#72016 (slices 1-3; slice 4 cumulative SSE stream-retry deadline

The stale-.pyc bug class (#6207, #60242, live WhatsApp report: gateway
ImportError 'cannot import name parse_model_flags_detailed' after /update)
has one shared shape: the checkout's .py files change while __pycache__
retains bytecode from the previous revision, and a later process trusts
the stale .pyc.
Update-time clears can never fully close this class: 'hermes update'
always executes the PRE-pull updater code, so hardening added to it takes
effect one update late — and a manual 'git pull' never runs the updater
at all.
Class fix:
- Launch-time guard in main(): compare the checkout fingerprint (cheap
file reads via _read_git_revision_fingerprint, no git subprocess)
against a .bytecode-fingerprint stamp; sweep __pycache__ once when they
diverge. Covers manual pulls, old updaters, ZIP restores — every entry
point (CLI, gateway service, desktop backend) passes through main().
- Record the stamp at all three update-time clear sites (git path pre-
install, git path post-install, ZIP path) so a normal update never
triggers a redundant launch sweep.
- Sibling site: 'hermes plugins update' + dashboard plugin update now
clear __pycache__ under the plugin dir after git pull (plugin trees
live outside the repo guard).
E2E validated: reproduced the stale-pyc shadowing (same-size same-mtime
source swap → old symbol wins in a fresh process), confirmed the launch
sweep restores the new symbol, no-ops when the checkout is unchanged,
and re-sweeps on the next pull. Sabotage-tested: reverting the sweep
fails 4 of the new tests.
Refresh update-sensitive modules before lazy backend refresh so an in-place git update does not keep using pre-pull module objects when newly pulled code imports fresh helpers.
Constraint: Issue #60242 reports post-update lazy backend refresh importing stale hermes_constants after a large Windows update.
Rejected: Only clearing __pycache__ earlier | the update process can still hold old modules in sys.modules.
Confidence: high
Scope-risk: narrow
Directive: Keep update-time lazy refresh guarded against in-process code skew after git pull.

Reshapes the salvaged fix so it recovers the `tsc: not found` build without
mis-diagnosing healthy trees.
The npm config forcing is dropped. It rested on the premise that an inherited
`npm_config_omit=dev` can beat the `--include=dev` CLI flag; npm resolves
command-line flags above environment config and filters `omit` by `include`,
so the flag already wins. Verified on npm 10 and 11.5.1: with
`npm_config_omit=dev` set and `--include=dev` passed, devDependencies install.
`npm_config_production` is worse than redundant — npm 9 removed it, so setting
it prints `npm warn config production Use --omit=dev instead.` on every
install.
The readiness probe now reads every root `npm run build` searches, not just
the workspace root. npm links a package's bin shims under the package itself
when it owns its lockfile (#42973), so a root-only check called a working tree
broken: it forced a redundant install, skipped the build entirely, and made
`hermes web` exit 1 on a layout that builds fine today.
The pre-build probe is gone with it. A build that works is never second-guessed
and no filesystem introspection gates it; recovery is driven by the failure
instead. When the build cannot resolve tsc or vite, we reinstall (visibly) and
retry before the generic delayed retry, which otherwise just reruns the same
command and leaves the stale dist in place forever. The lockfile-hash skip
still invalidates on an incomplete toolchain so the next update repairs itself.
Also drops the branches that changed behavior based on whether a test mock was
installed, and replaces the mock-call-count tests with real temp trees covering
both hoisting layouts, the Windows shim extensions, and each shell's wording of
an unresolvable binary.

hermes update could report a successful workspace npm ci while
devDependencies were omitted (production/omit-dev env leakage), leaving
tsc/vite unlinked. The subsequent web UI build then failed with
`tsc: not found` and fell back to a stale dashboard dist.
Force npm_config_include=dev on install, verify toolchain shims after
workspace install (and refuse to hash-cache a half tree), repair/reinstall
when node_modules exists without tsc/vite, prepend workspace .bin dirs to
PATH, and retry the build after a tsc/vite-not-found failure.
is_truthy_value(..., default=False) and getattr(..., False) disagreed with
compression.in_place: true from #38763, so partial/failed config loads fell
back into rotation mode and re-armed the pre-lease drift path. Also report
compression.in_place in hermes dump overrides so stale false values are visible.
Per hermes-sweeper review on #56671: the fallback exclusion matched any
canonical string starting with "custom" (e.g. "customproxy"), not just
the durable named-custom-provider syntax ("custom" bucket or
"custom:<name>" slugs). Narrow it to an exact/prefix match on that
syntax so unrelated vendor names aren't accidentally exempted from the
openrouter fallback.
Also clarifies the test suite: a properly configured custom:<name>
provider now resolves via resolve_custom_provider before this fallback
is ever reached (added upstream in 9a15fad0d6), so the existing test
was mislabeled as exercising that primary path when it was actually
exercising the fallback-safety-net case (missing/unresolved config
entry). Split into explicit primary-path and fallback-safety-net tests,
plus a regression test for the "customproxy"-style false positive.
_normalize_main_model_assignment() (POST /api/model/set, the endpoint
Desktop's Settings -> Model page uses to persist the main model slot) has
a fallback for a specific analytics bug: an older session row with no
billing_provider sends the model's bare vendor prefix as "provider"
(e.g. "anthropic" from "anthropic/claude-opus-4.6"), so the code detects
an unrecognized provider paired with a slash-bearing model and treats it
as that stray-vendor-prefix case.
Named custom providers are represented as "custom:<name>" slugs
everywhere else in the codebase (runtime_provider.py, model_switch.py),
but _KNOWN_PROVIDER_NAMES only lists the bare "custom" bucket. So picking
a named custom provider (e.g. "custom:litellm", a LiteLLM proxy fronting
Ollama) together with a slash-bearing model ("ollama/glm-5.2") looked
identical to the stray-vendor-prefix case and got silently rewritten to
provider: openrouter in config.yaml on save -- reassigning the provider
entirely, not just mangling the model id.
Exclude anything starting with "custom" from the fallback, matching the
guard the same function already applies later for the actual
normalize_model_for_provider call.

_MATCHING_PREFIX_STRIP_PROVIDERS includes "custom" so that manually typed
config values like "zai/glm-5.1" repair themselves for their matching
native provider. But "custom" is a generic bucket for arbitrary
user-defined endpoints, not a vendor identity -- unlike zai/gemini/xai,
where a matching alias really does mean "this prefix names the same
backend as the target provider."
_PROVIDER_ALIASES maps "ollama" -> "custom", so a model configured as
"ollama/glm-5.2" against a named custom provider (e.g. a LiteLLM proxy
fronting Ollama, which registers its routes as "ollama/<model>") had its
prefix stripped to bare "glm-5.2" -- a name the proxy doesn't recognize.
_strip_matching_provider_prefix now only strips a literal "custom/"
prefix when the target resolves to "custom"; an alias that merely
resolves to custom (ollama) no longer qualifies, since custom has no
vendor identity for it to redundantly repeat.

Root-context rm -f "$log_dir/lock" could follow a raced directory
symlink and unlink a foreign lock outside HERMES_HOME. Clear the
stale lock via s6-setuidgid hermes alongside mkdir, and assert
victim/lock survives the swap-race test.
Root-context log/run used to pathname-chown hermes-writable log paths,
which a hermes user can race through a symlink swap via the writable
log control FIFO. Create the leaf with s6-setuidgid hermes mkdir instead;
parent logs/gateways ownership stays a stage2 boot concern (#45258).
Every fallback/dedup/skip decision asks one question — 'is this candidate
the same backend as the one that failed, along the axis that failure
invalidated?' — but it was re-implemented inline at six sites across four
subsystems, each comparing whatever string was locally convenient. Each
incident fixed one site while the others kept the bug: #22548, #70893,
#59561, #72468, #62984/#54250/#57584.
agent/backend_identity.py now owns the concept: BackendIdentity (provider /
model / base_url axes), FailureScope (MODEL / CREDENTIAL / ENDPOINT — each
failure class invalidates a different axis), and should_skip_candidate().
Unknown axes never manufacture a skip (over-skipping strands failover; a
wrong try costs one RTT).
Migrated sites:
- chat_completion_helpers.try_activate_fallback: replaces the provider+model
early-exit (the #62984 bug: ignored base_url, stranding multi-endpoint
pools) AND _fallback_entry_is_same_backend_by_base_url (deleted)
- auxiliary_client._try_configured_fallback_chain +
_try_main_agent_model_fallback: replace label/model comparisons; auth and
payment map to CREDENTIAL scope, keeping the #59561 carve-out
- hermes_cli/fallback_cmd add: primary-match + duplicate checks now identity-
aware (#54250/#57584): same provider+model on a different explicit
base_url is a pool entry, not a duplicate
_mark_provider_unhealthy stays label-keyed deliberately: its only triggers
are confirmed 402s, which ARE credential-scoped.
Owner-level tests pin each incident's semantics by number; sabotage-verified
(removing the base_url axis fails the #62984 test).
`hermes -c`/`--resume` (continue last session) resolved the globally
most-recently-used session, then cd'd into *its* recorded cwd. So running
`hermes -c` from repo A could land you in repo B's session — the session
you last touched anywhere, not the last one *here*.
Now `_resolve_last_session` scopes to the current workspace first: the git
repo root when CWD is inside a repo (so all sessions across its
subdirs/worktrees group together), else the CWD itself — matching the
`workspace_key` identity `hermes sessions list --workspace` already groups
on. It falls back to the unscoped global MRU when no session matches the
current workspace, preserving the old behaviour for fresh directories.
Adds `workspace_key` param to `SessionDB.search_sessions` and a
`_workspace_key_clause` SQL helper that mirrors `workspace_key()`: a row
matches when its `git_repo_root` equals the key, or (legacy rows without
git metadata) when its `cwd` is at or under it.
Per Teknium: the caps should bound a single agent loop, not accumulate
over the whole session. Rename SessionCapConfig -> LoopCapConfig and the
config section session_caps -> loop_caps; move the counters into
reset_for_turn (invoked per turn via turn_context) so each turn starts
with a fresh budget; retune defaults 200 -> 50 (a single turn issuing 50
web searches / spawning 50 subagents is already pathological). Block
codes session_*_cap -> loop_*_cap and messages updated to drop the
/new-resets-the-budget guidance (irrelevant now that it resets per turn).
Tests flipped: the old persists-across-turn-resets assertion becomes
resets-each-turn.
Add per-session lifetime caps on web_search calls and subagent spawns
(defaults 200/200, matching Claude Code v2.1.212). Unlike the existing
per-turn tool-loop guardrails, these count over the whole session and
reset only when a fresh agent is built (/new, /clear). Hitting a cap
blocks the offending call and halts the turn cleanly.
- agent/tool_guardrails.py: SessionCapConfig + session counters on the
controller (in __init__, not reset_for_turn, so they persist across
turns). before_call() enforces caps first, independent of
hard_stop_enabled. delegate_task batches count each task.
- hermes_cli/config.py: tool_loop_guardrails.session_caps defaults.
- docs + tests (unit + E2E validated against a real AIAgent).
Follow-up to the salvaged #67409 search aliases: with kimi-k3 now in
the curated kimi-coding list (#68108), a Coding Plan key rendered TWO
rows for one model — curated 'kimi-k3' plus live-discovered bare 'k3'
(merge dedup was exact-string). Add model_alias_canonical() derived
from the same alias table and use it as the merge dedup key, so the
curated public slug wins and live-only models still surface.
Kimi Coding discovers the flagship as wire id `k3`. Picker search used
only that id, so typing "kimi" hid it next to every other kimi-* model.
Add picker-only search aliases without changing the wire id.
`hermes skills update` could silently replace a same-named skill from a
DIFFERENT registry — deleting the user's files and rewriting the lockfile's
recorded provenance. Two defects on main:
- tools/skills_hub.py: check_for_skill_updates fell back to *all* sources
(`... or sources`) when no adapter matched the recorded source, so any
registry with a same-named skill could satisfy the fetch and be reported
as an update — silently reassigning provenance. Now reports the entry as
`unavailable` instead of cross-registry fallback.
- hermes_cli/skills_hub.py: do_update called do_install with a bare, slash-
less identifier and no source constraint, letting _resolve_short_name fuzzy-
match a same-named skill in another registry. do_install now takes an
optional source_id pin that ABORTS (rather than falls back) when no adapter
matches, and do_update forwards the lockfile's recorded source as that pin.
Includes regression tests reproducing the cross-registry hijack.

Surgical reapply of #53505 by @LeonSGP43 onto current main (stale-base
cherry-pick conflicted in main.py):
- _refresh_active_memory_provider_dependencies() in hermes_cli/main.py,
wired into BOTH the git-pull update path (after lazy refresh) and the
ZIP update path — the provider's plugin.yaml bridge packages are not
in extras or LAZY_DEPS, so the core reinstall could strip/downgrade
them and the update flow never healed them (#53272 mem0ai).
- _install_dependencies(force=True) in memory_setup.py: hand every
declared spec to the resolver on update so missing AND version-drifted
packages are restored (no-op when satisfied).
- Skip guards: no provider / builtin store / memory.enabled=false.
Widened beyond the original PR for the #70636 half:
- _provider_pip_dependencies(): mode-aware expansion — Hindsight in
local/local_embedded mode needs hindsight-all (daemon + embedder), not
just the declared hindsight-client; setup installs it but plugin.yaml
can't express it, so update-time healing previously missed
hindsight-embed and the daemon stayed broken.
- Spec-aware import probing: version ranges in pip_dependencies
(mem0ai>=2.0.10,<3) no longer break the pip-name -> import-name
mapping.
Fixes#53272. Fixes the hindsight-embed half of #70636.
Widen the cherry-picked /diff base (#4839 by @SHL0MS) into one
cross-surface implementation, folding in the review feedback and the
best ideas from the two sibling PRs (#22703, #53527):
- tools/working_diff.py: shared git collection layer — unstaged
(default), staged, and all (vs HEAD) modes; untracked files folded in
via `git diff --no-index` so new files appear as additions (Codex
/diff parity); shlex-split arguments preserve quoted paths.
- CLI: handler moved to hermes_cli/cli_commands_mixin.py per the
current god-file decomposition (dispatch stays in cli.py), renders
through the rich console with a 400-line terminal-flood guard.
- Gateway: _handle_diff_command in gateway/slash_commands.py + dispatch
in gateway/run.py; fenced ```diff output truncated to 60 lines /
3000 chars before the platform senders apply their own per-platform
message clamps (tool-progress-style layered truncation). Localized
strings in all 17 locale catalogs.
- /diff session (from #53527): cumulative checkpoint-baseline diff of
everything Hermes changed, via new CheckpointManager.session_diff();
docstring records the retained-baseline approximation caveat from
review. Works on both surfaces; degrades with an actionable message
when checkpoints are off.
- Slack: /diff routed via /hermes diff (50-slash cap; keeps
telegram-parity test green and /version native).
- Registry: cross-surface CommandDef with staged|all|session
subcommands; docs: slash-commands reference (CLI + gateway tables +
both-surfaces list) and hermes-agent skill reference.
- Tests: tests/tools/test_working_diff.py (real git repos),
tests/hermes_cli/test_diff_command.py (real git + stubbed checkpoint
manager), tests/gateway/test_diff_command.py (end-to-end handler,
real checkpoint store), TestSessionDiff in
tests/tools/test_checkpoint_manager.py.

Extends the cherry-picked /context command (PR #52184) and prompt-size
attribution helpers (PR #66656) into one visual context view across
surfaces, and absorbs the per-component budget-visibility goal of the
/tokens proposal (PR #48470):
- agent/context_breakdown.py: pure renderers over the existing payload —
a 5x20 glyph block grid (1 cell ~= 1% of the model window), an
'Estimated usage by category' table with free space, and expanded
per-skill / per-toolset listings via compute_context_details(), which
reuses the prompt-size attribution mechanism (skills index-line bytes +
registry tool->toolset map) converted to the same chars/4 heuristic.
- cli.py: /context [all] renders grid + category table (+ expanded
listings) from the live agent and in-memory conversation history.
- gateway/slash_commands.py: /context appends the plain-text category
table (no grid — monospace not guaranteed on messaging platforms);
/context all adds the expanded listings. Fail-open: breakdown errors
never break the gauge.
- hermes_cli/commands.py: /context gains the 'all' subcommand; /version
demoted to /hermes version on Slack to keep the 50-slash cap.
- tests: renderer unit tests against synthetic payloads, registry test,
gateway /context + /context all + failure-degradation handler tests.
- docs: slash-commands reference + CLI guide entries.

`hermes prompt-size` reported skills as one <available_skills> block total
and tools as one json-bytes total, so there was no way to see which
installed skill or toolset actually dominates the fixed prompt budget.
Add two additive breakdowns to compute_prompt_breakdown (hermes_cli/
prompt_size.py):
- toolsets_breakdown: each resolved tool is attributed to its single
canonical registry toolset (registry.get_tool_to_toolset_map), summed by
group. Fully attributable — the grand total equals the existing
tools.json_bytes minus JSON array framing (2*count bytes).
- skills_breakdown: parsed from the rendered <available_skills> block, one
entry per skill with two honest, distinct numbers — index_line_bytes (the
always-on cost of listing the skill) and skill_md_bytes (on-disk SKILL.md
size, the real read cost paid only on skill_view). Sorted largest-first
by read cost.
render_breakdown prints both as sorted "Toolsets by size" / "Skills by
size" tables (skills capped at 20; --json carries them all). All existing
keys and output are unchanged.
Runs fully offline (dummy credentials, no network). Tests cover shapes,
largest-first ordering, per-tool attribution reconciling to the total,
namespaced-name parsing, and unmapped-skill handling.

A dedicated /context (alias /ctx) gateway slash command that gives a full
context-window view with:
- Usage gauge: visual bar + fraction + percentage + headroom
- Auto-compression threshold and how far away it is
- Compression count and how much the last one freed
- Cumulative session throughput (explicitly labelled as throughput,
NOT context size — each call re-sends the window)
- Cascading fallback: running agent → cached agent → SessionStore metadata
→ rough transcript estimate
Not included (per current-main design):
- Cache reporting removed: commit 446b8e239 intentionally removed cache
reporting from user-facing surfaces because providers that omit cached-token
details produce misleading values
- Sync DB calls replaced with async_session_store (current main requires
AsyncSessionStore with await)
Also rewords the /status tokens line from 'Cumulative API tokens (re-sent
each call)' to 'Lifetime tokens billed: ... (not your current context size;
use /context)' to reduce the recurring confusion that the cumulative figure
is the current context window.
Fixes salvation of PR #52184 (salvage commit replaces a 12K-commit-behind
fork branch with a fresh implementation against current main, incorporating
reviewer feedback from @whoislikemiha and the hermes-sweeper).
After N consecutive guardian denials in a session the deny message escalates to a hard-stop instruction. Inspired by ChatGPT Work auto-review circuit breaker.
Two halves close the 'legacy pythonw gateways survive updates forever' gap:
1. hermes update now regenerates the installed Scheduled Task / Startup
launcher scripts (gateway.cmd + gateway.vbs) during the gateway resume
phase. They are persistence artifacts written once at install time;
updates never touched them, so pre-aa2ae36c3f installs kept launching
the gateway through pythonw.exe forever — every descendant spawn
flashed a conhost (#54220/#56747) and, since #70344, the console-less
gateway died at startup with RuntimeError: sys.stderr is None (#71671).
The task /TR points at a stable script path, so rewriting the files
retargets it with no schtasks call and no UAC. No-op for modern
installs; best-effort so a failed refresh never fails the update.
2. _resolve_detached_python() normalizes a legacy pythonw.exe interpreter
to its sibling console python.exe when it exists, so the update
pause/resume argv-replay path (and any other caller handed a legacy
command line) respawns on the current design instead of faithfully
resurrecting the old one. Keeps pythonw when no sibling exists — a
failed respawn is worse than a console-less gateway.
