_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.
Read-only and locally computed: no provider calls, no prompt-cache impact.

`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.
Maps CLAUDE.md/AGENTS.md, permission allowlists, MCP servers, skills, and memories into their Hermes equivalents. Follows the openclaw migration pattern. Inspired by ChatGPT Work import-from-another-agent onboarding.
The sidebar labelled sections and workspace lanes `loaded/total`, which
read as a progress bar people expected to fill up rather than a count of
loaded rows. Pricing that label cost a COUNT(*) per profile database on
every sidebar refresh, purely so the numerator and denominator could
differ.
Pagination only needs to know whether another page exists, and that comes
free from the rows the query already returned: a window that comes back
full means more remain on disk. Sections now show the loaded count alone,
and the backend reports per-profile `profiles_truncated` flags in place of
`total` / `profile_totals`.
Compile and checksum-pin SQLite 3.53.4 in the published image, preserve Hermes' required SQLite features, and assert the final Python linkage plus FTS5 trigram behavior during image builds.\n\nMake doctor remediation install-aware so Docker users pull and recreate every Hermes container instead of running the inapplicable git updater.\n\nFixes #70480
The managed uv is installed with UV_UNMANAGED_INSTALL, which disables
'uv self update' by design — the swallowed failure left its embedded
python-build-standalone catalog frozen at bootstrap age forever.
python-build-standalone re-releases existing patch versions with fixed
SQLite (3.11.15 was re-cut with 3.53.1), so a stale catalog resolves
the same version number to the OLD vulnerable build, the probe rejects
it, and the patch-retry loop cannot recover because the fixed build
carries no newer number to try. Result: 'hermes update' printed a
guaranteed-failure provisioning warning on every run (issue #72093).
- When provisioning fails, re-bootstrap the Hermes-managed uv binary
via the official installer (the only supported refresh for unmanaged
installs) and retry provisioning once — only when the binary version
actually changed, so no wasted download cycles.
- Never touch a caller-supplied uv outside the managed path.
- Soften the failure report from alarming ⚠ to informational ℹ and say
why it is safe to wait: the WAL gate keeps databases out of WAL on
vulnerable builds, and the next update retries.
Verified: 56 unit tests green; sabotage run (retry block removed) fails
the 3 new retry tests; live E2E replaced a fake managed uv via the real
astral installer and the refreshed binary resolved the 3.11 catalog.
Fixes#72093
A providers: entry with only a default_model/model (no explicit models:
list) is un-narrowed — the singular field is just the active selection.
Section 3 derived has_explicit_models from the merged models list, so
the lone default_model entry counted as an explicit catalog and
suppressed the /v1/models probe for no-key endpoints, leaving a
one-line /model picker menu for local llama.cpp/Ollama/vLLM servers.
Track explicit models: declarations separately at group-build time
(mirrors section 4's declaration-tracking from #40542 / PR #61928) and
gate the probe on that instead.
Salvaged from PR #68984 by @vigilancetech-com (the probe_custom_providers
gate removal in that PR is not taken — the GUI no-probe gate is
intentional).
Completes #51690 on top of the salvaged #60378 timeout metadata:
- async_delegation: terminal 'stalled' events now carry structured
stall context (stalled_after_quiet_seconds, stall_threshold_seconds,
stall_phase idle|in_tool, stall_grace_seconds) on both single and
batch paths, persisted in the durable row so restart-restored events
keep it. Mirrors the sync path's timeout_seconds/timed_out_after_
seconds/timeout_phase from #60378.
- list_async_delegations(): exposes seconds_since_progress and live
children_activity (per-child api_calls, current_tool,
seconds_since_activity) sampled from the dispatch's progress_fn
outside the records lock; private monitor bookkeeping and callables
never leak.
- /agents (CLI + gateway): background delegations render per-child
activity rows, quiet-time hints, and the stalling state; gateway
section is new (previously async delegations were invisible there).
New locale key gateway.agents.background_delegations in all 17
catalogs.
Tests: stall-metadata event shape, live-listing projection, gateway
/agents rendering (real registry dispatch, sabotage-verified), sync
timeout metadata fields, non-timeout None contract.
Stop offering deepseek-chat/reasoner in the static catalog and point
fallback/aux defaults at the permanent v4 IDs. Keep retired aliases in
a detection-only map so /model deepseek-chat still resolves to deepseek.
DeepSeek cut off deepseek-chat and deepseek-reasoner on 2026-07-24.
Sending those IDs now returns HTTP 400; rewrite them (and fuzzy
reasoner names) to deepseek-v4-flash so saved configs keep working.
A long-lived gateway can have platform routing (HERMES_SESSION_* /
HERMES_CRON_AUTO_DELIVER_*) mirrored in os.environ from a previous turn.
_default_spawn() copied that process environment verbatim into detached
kanban workers, so a worker calling kanban_create treated the inherited
chat/topic as its origin and auto-subscribed the child task — the task's
terminal notification then woke an unrelated chat.
Strip every registered session-context routing key from the worker env
unconditionally (the dispatcher is detached from every conversation);
board, workspace, task, branch, profile, model, and credential
propagation are unchanged.
Salvaged from PR #69181 (both commits squashed; the PR's second commit
fixed the first's engagement-latch assumption).
Fixes the boot-storm half of issue #29905: kanban_notify_subs.last_event_id
defaulted to 0, so a subscription created on an already-active task replayed
the task's ENTIRE terminal-event backlog on the next notifier tick. With
many stale subs (27 observed in the report) a gateway boot after downtime
burst 100+ notifications in one go.
add_notify_sub now snaps the cursor to COALESCE(MAX(task_events.id), 0) for
the task inside the same INSERT, so new subscriptions start caught up and
only receive events that occur AFTER subscribing. The gateway slash-command
and kanban-tool auto-subscribe paths run at task creation, where the
snapshot is just the 'created' event — behavior there is unchanged.
Stale fixtures that asserted the literal 0 creation cursor now assert
'cursor unchanged/unclaimed' instead, which is what they actually meant.
Salvaged from PR #63001 (reduced scope): probe each board with the new
read-only kanban_db.count_notify_subs() before the writable connect(),
so boards with zero subscriptions are never opened writable on the 5s
notifier tick (no schema migration, no WAL/-shm sidecar churn, no
checkpoints).
The PR's machine-global .notifier.lock singleton gate was deliberately
NOT salvaged: a lock-winning default-profile gateway cannot deliver a
secondary profile's subscriptions in standalone-profile deployments
(profile routing fails closed in _authorization_adapter), so the lock
could suppress delivery entirely. The probe captures the per-tick cost
win without that regression.
