Review folds from the formal gate battery:
- _SPLIT_FAILURE_COOLDOWN_SECONDS = 60 replaces the bare literal, with a
comment pinning WHY it is the timeout ladder's first rung (transient
lease/DB condition) rather than the 600s summary-provider cooldown.
- publish_compression_child docstring now states the compression_lock_holder
condition on the refresh guard.
- Dropped 2 of 3 extracted unit tests as duplicates of existing coverage in
test_compression_rotation_state.py / test_context_compressor.py; kept the
force-bypass test (only site pinning that behavior for split failures) and
the E2E test (now asserting the named constant).
The salvaged unit tests drive _record_compression_failure_cooldown directly;
this drives the real _compress_context split-failure path (archive boom on a
real SessionDB) and asserts the cooldown recording fires with the
session_split_failed error class.
Two narrow repairs for #97948 symptom B (large-session rotation aborts with
'Compression lease lost before publication' / session_split_failed, then the
next turn re-runs the identical doomed compression):
1. publish_compression_child gains require_lease_refresh: the lease is
extended inside the same transaction as the expiry check (same conn, no
TOCTOU), giving a worker whose refresher thread died from transient DB
failures one final chance to keep its completed work.
2. A failed compression split now records a 60s failure cooldown, so the
next turn cannot immediately re-trigger the same compression.
Salvaged from #98137 (author: vsd2807). The timeout-reconciliation half of
that PR is NOT carried: it has a blocking review (runtime sid vs persisted
session_key, one-shot check cannot observe a 6-minute commit, no identity
projection) and needs a redesign.
The preflight trigger charged reasoning/reasoning_content on every assistant message while the tail-budget walks charged newest-turn-only (#73624), so reasoning-heavy codex_responses sessions fired compaction forever while the walk protected everything (middle_window_tokens=0, no_progress every turn, each attempt a full aux summarization).
Wire truth: the codex_responses input builder never ships the text thinking keys (encrypted codex_reasoning_items carry the chain and were already charged unconditionally by both sides), so the trigger overcounted reality; echo-back chat-completions families (DeepSeek/Kimi/MiMo thinking mode) replay stored reasoning_content on every turn, so there the walk undercounted. New single wire-truth predicate message_sanitization.stale_thinking_reaches_wire() now drives BOTH sides: trigger estimates exclude stale thinking on non-echo routes; tail/prune walks charge it on echo routes.
Also: reasoning/reasoning_content double-count fixed in both estimators (wire ships at most one; +53% overcount vs provider prompt_tokens per issue comment), and the commit-layer no_progress path now arms the structural no-op backoff so an unchanged-transcript compaction cannot re-fire every turn (defense in depth; overlaps the #96775 re-entry class).
PR #98628 removed _build_chunk_digests, so the two lean chunk-digest
cancellation tests reintroduced by the #97512 cherry-pick target a
deleted mechanism — removed. The #96775 stall-interrupt assertions now
match the stall_interrupted marker inside the strategy/kind-stamped
durable error instead of assuming it is the prefix.
The bounded-grace join only applies where the overlap hazard lives: a
total-ceiling expiry over a still-streaming worker (#97488). The
idle-stall path keeps its prompt detachment so the stall-fallback retry
preserves the #76354 S3 latency contract (silence never approaches 2x
the idle budget); its late unwind stays safe behind the fence poison
and attempt-generation supersession.
Sabotage-verified regression tests: bounded-grace worker teardown on
ceiling (cooperative join + uninterruptible orphan with retained
lease), durable strategy/kind-stamped backoff that survives a simulated
gateway restart against a real temp SessionDB, success clearing the
backoff, superseded-attempt late results discarded, and the
transient-block signal (type-pinned against MagicMock agents).
Pin both AuxiliaryExplicitCancellation and commit-fence cancellation, keep early /stop cooldown-neutral, merge with a longer live deadline, and prove force=/compress still bypasses the automatic brake.
The lean tail mode's per-chunk digest loop (_build_chunk_digests) issued up
to 28 extra call_llm requests sequentially per compaction attempt. With lean
now the default (#95571), users on slow auxiliary routes hit 7-11 minute
compactions (#96603). Remove the loop entirely: a lean compaction attempt now
makes EXACTLY ONE auxiliary LLM request — the main summary call.
- The detailed session log is folded into the single summary request: the
lean prompt template gains a '## Detailed Session Log (oldest first)'
section carrying the digest prompt's HARD RULES (identifiers verbatim,
dense bullets, transcript-is-data). Output guidance grows by
_LEAN_SESSION_LOG_BUDGET_TOKENS = 4,000 tokens on top of the scaled
summary budget — the old worst case (28 x 1,400 digest tokens) was spread
across many requests and mostly re-covered tool noise; a single dense
4K-token log inside one response preserves the load-bearing record while
staying well inside one aux response (the summary call still sends no hard
max_tokens, so no provider cap can truncate it mid-section).
- Input sizing: oversized regions (500K+ chars) are EVEN-SAMPLED across the
whole region (_sample_summary_input: 8 proportionally spaced slices,
oldest-to-newest, explicit '[... N chars elided ...]' markers, last slice
anchored to the newest end) instead of head+tail truncated, so session-log
coverage stays uniform. Legacy mode keeps _bound_summary_input unchanged.
- The LLM-free anchor index still runs over the FULL region, and the
session_search recovery footer is unchanged.
- Dead code removed: _build_chunk_digests, _LEAN_DIGEST_* constants,
_LEAN_DIGEST_PROMPT, _serialize_turns_for_digest, _digest_worthy,
_LOW_SIGNAL_TOOL_RE, the _lean_pristine_tools snapshot, and the
sibling-call route echo (_SUMMARY_ROUTE_CONSUMED /
attempt_summary_route_kwargs — no remaining callers; the single-use
summary pin semantics are unchanged).
- Tests pin the new contract (exactly one call_llm in lean mode; session-log
section lands in the summary; oversized regions sampled with elision
markers, never a second request; anchor index + recovery footer present).
Sabotage-verified: restoring a second call_llm makes the call-count test
fail. Docs and the compaction eval wording updated to stop claiming
per-chunk calls.
Fixes#96603.
The #96155 fix (#96644) made the turn-prologue preflight estimate the
checkpoint-pruned native Responses payload, but the independent mid-turn
pre-API pressure guard in conversation_loop still estimated the full
assembled durable history. On a compacted native-Codex session the
generic figure overstates the wire by orders of magnitude (the issue's
deterministic probe: 1,037,241 generic vs 6,036 pruned, 171x), so the
guard false-tripped a 600-second local compression the main request
never needed — the live sequence shows the actual request then fit at
164k input tokens against a 765k threshold (#96995).
Extract the guard's pressure figure into _midturn_request_pressure_tokens
and mirror the turn-prologue: when native Responses compaction is proven
eligible, use estimate_native_responses_preflight_tokens (system prompt
and tools included, checkpoint-pruned); otherwise keep the generic
message+tools figure. Passing the assembled api_messages alongside
effective_system counts the system prompt exactly once — the estimator's
converter skips system-role rows and adds the prompt separately.
total_chars (verbose log proxy) and the non-codex paths are unchanged.
Fixes#96995
* refactor(skills): shipped-set slim — 15 skills to optional, github six-way merge, pdf absorbs OCR+nano-pdf, channel-gated teams pipeline
Maintainer-directed shipped-skills curation (skills index 1,900 -> ~1,400
tok/call on desktop; every session pays the index, so this is a per-call
diet on all installs):
- optional-skills moves (installable via skills hub, history preserved):
creative comfyui/ascii-art/excalidraw/pretext/sketch/touchdesigner-mcp;
ALL of mlops (huggingface-hub, llama-cpp, serving-llms-vllm,
weights-and-biases, evaluating-llms-harness — subcategory structure
kept); research-paper-writing (55 supporting files, 17.3K-tok load);
openhue; blogwatcher (first taught the cronjob monitor-field watch
pattern + web_extract instead of pre-cron manual workflows)
- DELETED session-librarian (Aug-12 'inspired by Perplexity Computer'
port, never maintainer-intended; session_search covers discovery)
- github: six skills (auth, issues, pr-workflow, issue-to-pr,
code-review, repo-management) merged into ONE software-development/
github skill — routing body + complete per-workflow references;
benbarclay authorship credited; codebase-inspection rides along;
discipline pins from test_github_issue_to_pr_skill.py preserved
against the reference body in the new test_github_skill.py
- pdf absorbs ocr-and-documents + nano-pdf as references/ + scripts
(extract_pymupdf, extract_marker converted to the argparse house
standard its contract test enforces)
- NEW session_platforms frontmatter gate (metadata.hermes): hides a
skill from the index on gateway channels it is not for; fail-open on
unknown platform; teams-meeting-pipeline gated to [teams, cron]
- blocked-page-recovery: research -> new web category; trigger-first
description ('Use when a fetch fails: 403/429, paywall, WAF, bot
wall.') so the model actually reaches for it on blocked fetches
- docs regenerated via generate-skill-docs.py (195 pages); related_skills
swept repo-wide; tests: 1672 passed (2 openclaw failures pre-existing
on clean main, Windows-local)
* chore: ignore .skills_prompt_snapshot.json (local index cache, accidentally committed)
The supporting-files block emitted every file twice per line
(relative -> absolute), duplicating an identical directory prefix
hundreds of times on reference-heavy skills. The absolute base is
already stated once in the [Skill directory: ...] header and the
footer example, so each line now carries only the relative path.
On hermes-agent-dev (462 supporting files) the activation message
drops from 42,145 to 29,042 o200k tokens (-13,103, -31%) — paid on
every session that preloads or invokes the skill.
* feat(compaction): always rebuild the system prompt at the commit boundary — keep-prompt now gated on byte equality of the LIVE builder output; plugin sections re-render with fail-open to last good bytes
* feat(clock): 'Conversation started' resolves through the session-lineage ROOT — a compacted/rotated session keeps its original birth date (Bot Mode forever-chats know when they were first born)
* test: retire old-contract pins — plugin sections re-render at invalidate (freeze stays restore-only), commit boundary always runs the live builder, byte-equal keep preserves object identity
The bundled plan skill's auto-generated slash command fell off the capped
Telegram/Discord command menus for most installs (skills are the only tier
trimmed at the platform caps, alphabetically — 'plan' sat past the cutoff at
index 57 of 82 bundled skills). Converting it to a first-class CommandDef
gives it a guaranteed core-tier menu slot on every platform.
- agent/plan_prompt.py: build_plan_prompt() — plan-mode rules + authoring
craft distilled from the retired skill; prompt-injection pattern like
/learn and /init (no engine, no model-tool footprint, cache-safe).
- CLI: _handle_plan_command mixin handler (pending-input injection).
- Gateway: /plan branch rewrites event.text and falls through (role
alternation preserved).
- TUI: command.dispatch branch ('plan' was already in
_PENDING_INPUT_COMMANDS).
- Removed skills/software-development/plan/ + docs pages (EN + zh-Hans),
catalog rows, sidebar entry, related_skills references.
- PROTECTED_BUILTIN_SKILLS is now empty (mechanism kept); dependent
curator/usage tests moved to monkeypatched sentinels.
Salvages #67292 by @webtecnica (credit: first /plan command submission,
issue #67264); reworked from inline planning prompt to the prompt-injection
pattern with workspace-saved plans. Closes#67264, closes#36821 (empty
/plan infers task from conversation context).
Addresses the hermes-sweeper review on #53765. The in-place /model switch
helper (_apply_switched_provider_request_overrides) derived a custom
provider's extra_body by provider *name* only, while build-time matching in
agent_init._merge_custom_provider_extra_body matches by provider key, base_url,
AND model. So a different model selected at the same named endpoint could
inherit an extra_body configured for another model.
Reuse the shared agent_init._custom_provider_extra_body_for_agent matcher
(provider key + base_url + model), sourcing custom_providers from the
init-time agent._custom_providers cache (fresh-load fallback if absent). A
stale extra_body is always cleared when no entry matches; non-provider
overrides (service_tier / speed from /fast) are preserved.
Tests: add nonmatching-model and endpoint-mismatch regressions; update the
existing switch tests onto the model/base_url-aware matcher.
Third in the series. The gateway rebuild path (previous two commits)
carries a custom provider's `request_overrides` (`extra_body`, e.g.
`chat_template_kwargs`) into the agent, but the *in-place* live switch used
by the TUI dashboard and the CLI — `agent.switch_model()` ->
`agent_runtime_helpers.switch_model()` — swapped
model/provider/base_url/api_key without ever updating `request_overrides`.
So a `/model` switch to a thinking-enabled custom provider in the TUI/CLI
kept the previous provider's `extra_body`.
`switch_model()` now re-derives the switched-to provider's
`request_overrides` (via `_get_named_custom_provider`) and applies it in
place, preserving non-provider overrides (`service_tier`/`speed` from
`/fast`). Logic factored into `_apply_switched_provider_request_overrides`
for testability.
Adds tests/agent/test_switch_model_request_overrides.py.
The consumed-but-uncommitted rotation verdict was process-local
(_SPENT_ROTATION_FINGERPRINTS), while the credential it protects is
explicitly cross-process: ~/.claude/.credentials.json is shared by every
Hermes profile and process. A fresh interpreter could lease the stale
access token or re-POST the already-spent single-use refresh token and
burn the credential family into invalid_grant.
- Persist non-secret one-way fingerprints to a sidecar registry next to
the shared singleton source (claude_code / hermes_pkce), written under
the same path-keyed cross-process lock that serializes refreshes.
- Consult the sidecar in the pool resolver, the pool refresh path, and
the direct claude_code resolver/refresh before leasing or POSTing.
- Two-process regression: A rotates and loses the commit; B (fresh
interpreter, empty local registry) must neither lease the stale pair
nor POST the spent refresh token. Plus a no-verdict control.
Closes the remaining P1 from the exact-head review of f228439b on
PR #87891.
Two runtime blockers from the exact-head review of c057ef5.
1. A sanitized `claude_code` pool row was treated as token authority.
`claude_code` is a borrowed source: it is absent from the owned-source
allowlist, so `sanitize_borrowed_credential_payload` strips `access_token`
and `refresh_token` before the row reaches `auth.json`. `load_pool()`
re-hydrates the live pair from the singleton on every load, which is what
makes `~/.claude/.credentials.json` — not the pool store — authoritative
for this source.
`_sync_anthropic_entry_from_pool_store()` re-read that persisted row during
refresh. Being token-less, it "differed" from the live entry, so it was
adopted as a rotation performed by another process: `_refresh_entry()`
replaced a usable credential with an empty one and returned it before
`_claude_code_credentials_lock()` and the authoritative re-read were ever
entered. The empty OAuth entry then stayed selectable, because the
empty-runtime-key guard in `_available_entries()` covered API-key rows only.
Repairs: the pool-store sync refuses borrowed sources outright (plus a
defensive refusal of any token-less row, for future sources that sanitize on
write); the `claude_code` branch of `_refresh_entry()` now runs before the
generic adopt-and-return shortcut, so the path-keyed lock and the
authoritative re-read are always entered before deciding to POST or adopt;
and an OAuth entry with no access token is never leased.
2. A failed commit still fell through to the same spent credential.
`_refresh_oauth_token()` correctly returns None when the refresh POST
rotated the single-use token but the replacement could not be committed.
That verdict did not survive the caller: `resolve_anthropic_token()`
continued to `_resolve_anthropic_pool_token()`, which enumerates read-only
(`clear_expired=False, refresh=False`) over a pool that `load_pool()` had
just re-seeded from the unchanged singleton — so the pair whose refresh half
was already spent came back as a healthy token, and
`_refresh_provider_credentials("anthropic")` reported success and evicted
its cached clients.
Repair: every commit-failure path records the consumed pre-rotation pair as
non-reversible fingerprints (bounded, process-local), and both the Claude
Code file resolver and the pool resolver refuse a credential whose
fingerprint is on that list. `_refresh_provider_credentials("anthropic")`
consequently returns False when the spent family is the only credential,
while genuinely independent pool credentials stay eligible.
Coverage: `test_anthropic_borrowed_row_authority.py` starts from
`load_pool()` reading an actually persisted, actually sanitized row, forces
a refresh, and asserts the full pair survives with exactly one POST and one
commit, that the shared-file lock is entered, and that no empty OAuth entry
can be leased. `test_anthropic_spent_rotation_verdict.py` takes the full
resolver path: successful POST plus failed commit must make
`resolve_anthropic_token()` return None, make
`_refresh_provider_credentials("anthropic")` return False, and keep the
spent fingerprint out of every lease — with a control proving a successful
commit quarantines nothing and an independent credential still resolving.
Five of the seven new borrowed-row tests fail on the previous head, and the
three resolution tests fail with the verdict disabled.

`agent/anthropic_adapter.py` was 3,423 lines and this PR adds another auth
boundary to it. Split along the seams that were already there, so the
credential surface this PR changes has a single owner instead of being
interleaved with request building:
- `agent/anthropic_endpoints.py` (258) — base-URL/endpoint-family predicates.
Pure functions over a URL string, which is what lets both of the modules
below depend on it without a cycle.
- `agent/anthropic_message_convert.py` (1,225) — OpenAI-style to Anthropic
Messages payload conversion: model ids, tool schemas, content/thinking
blocks, tool_use pairing, cache_control, screenshot eviction, blank-block
scrubbing.
- `agent/anthropic_credentials.py` (910) — credential sources, the OAuth
flows, and the refresh commit (`CredentialPersistError` and both singleton
writers).
- `agent/anthropic_adapter.py` (1,215) — client construction and the Messages
API call, re-exporting every name from the three modules above so existing
`from agent.anthropic_adapter import ...` imports keep resolving. The
re-export surface was diffed against the pre-split module: nothing dropped.
Call sites that read a moved name through the adapter's namespace at runtime
(`credential_pool._refresh_entry_impl`, `auxiliary_client`) now import it from
the defining module, so there is one patchable seam rather than two bindings
that can disagree. The tests that monkeypatched those seams were retargeted to
match; no assertion was changed.
No behavior change.
Anthropic OAuth refresh tokens are single-use: the POST that returns a new
pair invalidates the one that was sent. The replacement therefore only
becomes real once it reaches its authoritative store -
~/.claude/.credentials.json for claude_code entries,
~/.hermes/.anthropic_oauth.json for hermes_pkce ones. Both writers caught
OSError/IOError, logged at debug level and returned nothing, so no caller
could tell a durable commit from a failed one.
That let a refresh spend the only refresh token, report success, and leave
the consumed pre-rotation pair on disk. _seed_from_singletons() re-reads
those files on every load_pool(), so the next process seeded the spent pair
back over the fresh pool row and the following refresh replayed a consumed
token (invalid_grant / refresh_token_reused) - exactly the failure this PR
set out to remove.
- _write_claude_code_credentials() and _write_hermes_oauth_credentials()
now raise CredentialPersistError instead of swallowing the write error.
- _refresh_oauth_token() treats a failed commit as a failed refresh and
returns None rather than handing back an access token whose refresh half
was lost.
- _refresh_entry_impl() fails closed on both the primary and the recovery
path: the rotated pair is never marked, persisted or returned, and the
entry is quarantined DEAD with a credential_persist_failed reason so it
leaves rotation and surfaces as an explicit re-auth instead of a silent
fallback to another provider. The retry path now commits to the singleton
before persisting the pool row.
- _upsert_entry() no longer treats re-seeding a borrowed source as a
rotation. Borrowed rows (claude_code, env-backed) are written to auth.json
without their secret, so comparing the re-seeded token against the empty
stored value reported a rotation on every load and cleared the DEAD state
the previous process had just written - resurrecting the quarantined,
already-consumed credential on restart. It now compares the incoming
token against the row's secret_fingerprint.
Adds failure-injection coverage for both writers, the direct resolver, the
claude_code and hermes_pkce pool paths and the retry path, each asserting
that a reload cannot bring the pre-refresh pair back as a usable credential.
Add a cross-process lock over the shared ~/.claude/.credentials.json file
so concurrent Hermes processes racing a claude_code-sourced Anthropic
refresh resync instead of losing the update (mirrors the existing
per-profile auth-store lock, kept as the outer lock per the documented
lock-ordering invariant).
Remove the dashboard-triggered Anthropic PKCE OAuth flow entirely rather
than continue patching it: an unattended HTTP endpoint minting Claude
Pro/Max subscription tokens outside Anthropic's own client sits on the
wrong side of Anthropic's OAuth usage policy. The provider catalog entry
is now flow == "external", pointing at `hermes auth add anthropic`
(terminal PKCE, unaffected, out of scope). Drop the now-dead PKCE
functions/constants and the tests that exercised only that removed code.
Dashboard PKCE login reused the code_verifier as the OAuth state (leaking
it and disabling CSRF validation) and never checked state on callback --
the same class of bug already fixed for the CLI flow. Credential-pool
refresh excluded "anthropic" from the cross-process lock Codex/xAI already
get, so concurrent Hermes processes racing a single-use refresh token could
leave the loser stuck exhausted with no recovery for hermes_pkce/dashboard
sources. The dashboard OAuth save also never cleared a stale
ANTHROPIC_API_KEY, which resolve_anthropic_token() prioritizes over the
OAuth pool entry by design -- so a leftover key silently kept billing
pay-per-token after a Claude Pro/Max login.
A concurrency stress test written to validate the refresh-race fix under
load surfaced a fifth, unrelated bug: _auth_store_lock()'s Windows
lock-file "ensure content" write was unguarded and could raise an uncaught
PermissionError under real contention -- affecting every single-use-token
provider sharing that lock, not just Anthropic.
Fixes#87887, #87888, #87889.
The chat_completions and transport-parity Mistral tests pinned the
same branch with different reasoning_config shapes ({effort:none} vs
{enabled:False, effort:none}) — behaviorally identical since effort
short-circuits first, but the drift reads as a semantic difference.
Align both to the explicit form. Also scope the port-guard comment to
the try/except shape it actually shares with hermes_cli/models.py.
The initial /btw implementation (#97937) answered from a rendered
plain-text transcript digest — truncated context, cold-written tokens on
every question. Teknium's call: reuse the self-improvement review fork
instead, which keeps the entire prompt cache stable for the fork and
gives it the complete conversation for very cheap.
- agent/background_review.py: extract the review-fork construction into
build_cache_parity_fork() — same runtime/credentials as the parent,
byte-identical system prompt / tools[] / reasoning config on the
same-model path, shared session_id for prefix warmth, full persistence
detachment (no state.db writes, no rotation, no external memory,
in-place-only compaction). The review thread now calls the helper;
behavior unchanged (full review test suite green).
- agent/side_question.py: /btw prefers the fork when a live parent
AIAgent exists — replays the untruncated snapshot as warm cache reads,
denies every tool at dispatch via an empty thread whitelist (tools[]
stays byte-identical for cache parity), attributes usage to the parent,
and trims a mid-turn snapshot tail so role alternation holds. The
one-shot digest remains as fallback (no live agent = cold cache anyway,
and any fork failure degrades gracefully).
- CLI passes self.agent, TUI passes the session agent, gateway looks up
the chat's cached agent (parity with how turns reuse it).
Live-verified: /btw on the worktree runs the fork path (agent.log shows
the side question as a forked conversation turn on the parent session_id
with the full history replayed), answers correctly from context.
Addresses the automated review on this PR:
- _profile_declared_efforts falls back from provider name to the
endpoint's host (via model_metadata's URL->provider map), so a named
custom provider pointed at api.router.com — which the host mandate
already routes onto this transport — gets the catalog clamp instead
of the default vocabulary and a Router 400.
- _parse_efforts validates catalog levels against EFFORT_LADDER at
ingest, logging and dropping unrecognized tiers; a model whose whole
vocabulary is unrecognized stays out of the map (transport defaults)
instead of passing the requested effort through unclamped.
- fetch_models dedupes ids while preserving Router's deliberate listing
order.
- plugin.yaml credits the human contributor per repo convention.
Ramp Router is an OpenAI Responses-compatible LLM gateway at
https://api.router.com/v1 that routes each request across upstream
providers (OpenAI, Anthropic, xAI, Fireworks, ...) with server-side
fallbacks and spend controls. Nous asked for a PR adding it as a
provider, so:
- plugins/model-providers/router/: RouterProfile plugin —
api_mode=codex_responses, RAMP_ROUTER_API_KEY auth,
RAMP_ROUTER_BASE_URL override, live account-scoped catalog via
GET /v1/models (no hardcoded fallback_models: IDs are key-scoped and
Router's docs mandate runtime catalog reads).
- hermes_cli/providers.host_mandated_api_mode +
runtime_provider._detect_api_mode_for_url: api.router.com ->
codex_responses. The host is Responses-only — POST /v1/chat/completions
does not exist and 404s — so this is a genuine host mandate (exact
hostname match per #32243, mirroring the api.meta.ai precedent).
- providers/base.py: new overrideable supported_reasoning_efforts(model)
hook (tri-state: None=defer, ()=model takes no reasoning params,
tuple=clamp set). Router validates reasoning.effort per model and
returns HTTP 400 invalid-argument on levels outside the model's
published vocabulary, and 400 unsupported_parameter when a
non-reasoning model receives any reasoning field (both verified live).
The profile answers from a cached copy of the catalog's
router.capabilities.reasoning block: cache-only on the hot path,
seeded for free by fetch_models(), disk-mirrored across processes
(/cache/router_catalog.json), background-warmed when cold
— same design as the OpenRouter reasoning-caps clamp on the chat path.
- agent/transports/codex.py: consult the profile-declared vocabulary in
the generic effort-clamp branch (xai/actual/github branches untouched;
profiles that do not override the hook see no behavior change).
- cli-config.yaml.example + adding-providers.md + providers/README.md:
document the provider, the host mandate, and the new hook.
- tests: behavior contracts for the host mandate/URL detection/spoof
rejection, profile registration + auth auto-registry wiring, catalog
parsing, and transport clamp/suppression/fallback paths.
Verified live against api.router.com (Aug 2026): one-shot chat,
streaming SSE, tool calls + parallel_tool_calls, encrypted-reasoning
replay on OpenAI-served models, function_call_output follow-up turns on
OpenAI- and Fireworks-served models; store:false / prompt_cache_key /
include:[reasoning.encrypted_content] / reasoning.summary accepted
across backends; effort clamp confirmed to convert a would-be 400
(xhigh on o3) into a successful request via the disk mirror.
/bg (formerly /background, which is retired) keeps the existing semantics:
spawn a fresh, independent agent session in the background.
/btw is now its own command matching the convention other harnesses use:
ask a quick side question ABOUT the current conversation without
interrupting it. A one-shot auxiliary LLM call (main model by default,
overridable via auxiliary.side_question.* in config.yaml) answers from a
read-only transcript snapshot — the live session's history, role
alternation, and prompt cache are untouched, and the current turn keeps
running.
Surfaces wired: CLI (inline mid-run dispatch), gateway (all messengers,
busy-dispatch table + idle dispatch, i18n across all 17 locales), TUI
(prompt.btw RPC + btw.complete event), Discord native slash, relay
command manifest, desktop exec routing, docs (EN + zh-Hans).
* test(system_prompt): cover session-start anchoring + fix Windows-portable expectation
- Add TestSessionStartLike unit tests for _session_start_like(): session-id
embedded timestamp, session_start fallback, now fallback, non-matching id.
- Add a build-level regression: a session started Jan 1 must still render
'Conversation started: Thursday, January 01' when the prompt is rebuilt
on Jan 2 (the rebuild-drift bug).
- test_coding_prompt_preserves_legacy_workspace_order hardcoded '/hermes'
while production renders str(Path('/hermes')) — backslash on Windows made
the suite fail on Windows (CI runs Linux, so it was never caught). Build
the expectation via str(Path()) to match production on every platform.
* fix(system_prompt): anchor 'Conversation started' to the real session start
The timestamp line stamped hermes_time.now() at system-prompt build time.
The prompt is rebuilt on compression, fresh-agent gateway turns, and
resume-without-stored-prompt, so the date silently advanced to whatever
day the prompt was last rebuilt — a chat that started on Wednesday read
as 'Conversation started: Thursday' after a Thursday-morning resume,
contradicting the fresh per-turn time hint.
Resolve the true start via _session_start_like(): the timestamp embedded
in the session id (YYYYMMDD_HHMMSS_..., immutable for the session life)
-> agent.session_start -> now() only as last resort. Box-local stamps are
attached to the box's local zone then converted to the rendered zone so
the date is consistent with the per-turn clock. The line stays date-only
and is now byte-stable for the whole session (never moves on rebuild),
preserving prefix-cache KV. The zone suffix and _bot_chat_timeless_prompt
behaviour are untouched.

- Widen opencode_zen_free_runtime healing to the union of the static floor,
the in-process live memo, and the SWR disk cache — a newly-live free model
now heals opencode-go/zen selections without a release (sibling site the
original PR missed).
- Memoize _fetch_opencode_free_models() in-process (5 min, negative caching
included) so direct provider_model_ids() validation callers don't each
block on a network round-trip or timeout.
- Drop delisted x-preview-f-free from the offline floor and setup.py sample
list (offline fallback must not offer a model that 401s); add the newly
live deepseek-v4-flash-free / mimo-v2.5-free to setup.py.
- Update stale test fixtures to a live exemplar; add regression tests for
memoization, negative caching, and union healing; docs note in providers.md.
* refactor(prompt): diet the memory/skills guidance block — schema-taught curricula removed, form rule + pruning contract kept (537 -> 223 tok in the combined block)
* polish: literal check-glyphs in source; memory capacity posture — save proactively, replace/consolidate when full
* refactor: single spine for memory/profile guidance — form rule + capacity posture written once, variants differ only in opening frame
* refactor: ONE memory-guidance builder — frame adapts to enabled stores, body written once, positive posture leads (maintainer direction)
* fix wording: memory is loaded per SESSION, not injected per turn (maintainer correction)
Final /simplify-code pass on the full diff: after the content-digest
rework, _creds_cache_key had become a wrapper with zero production
callers — get_vertex_credentials inlined the same read/except dance —
kept alive only by its own tests. One helper now owns the
(bytes, cache_key) resolution for all three cases (ADC sentinel,
readable file, unreadable fallback); prod calls it, tests target it.
No behavior change: 10/10 green, same mutation-check results.
test_every_marker_emitting_call_site_goes_through_the_central_clamp read
production .py files with a regex and pinned an exact call-site count --
the change-detector / reads-source-in-tests antipattern AGENTS.md bans
outright. Replaced with a test that drives the real
plan_cache_sections_for_destination fan-in and asserts the emitted wire
markers: ttl=1h on the measured opencode-go route, ttl stripped on the
unmeasured opencode route. Mutation-checked: emptying
MEASURED_1H_PROVIDERS turns it red.
`effective_cache_ttl` evaluates the generic `is_qwen_model` clamp before any
route-level allowance, so a configured `prompt_caching.cache_ttl: 1h` is
silently rewritten to `5m` for every Qwen model on opencode-go. Reproduced on
this commit's parent, no provider traffic:
effective_cache_ttl('1h', 'opencode-go', 'qwen3.7-plus') -> '5m'
_build_marker('5m') -> {'type': 'ephemeral'}
A repair for this exists historically -- payload d6b33faae1, merged as
a43fe4918d -- but neither commit is reachable from current main
(`git merge-base --is-ancestor` returns non-zero for both), so the regression
is live on this lineage.
Restores the precedence fix: MEASURED_1H_PROVIDERS (an allow-list holding only
opencode-go, the one route measured with a delayed read past five minutes) is
consulted ahead of the generic Qwen clamp, with NO_1H_TIER_MODELS nested inside
it for models measured to ignore the tier even on a capable route.
opencode-go stays in ALIBABA_FAMILY_PROVIDERS. That set is also the
cache-marker-layout opt-in read by
agent_runtime_helpers.anthropic_prompt_cache_policy, so narrowing it would turn
working five-minute caching into *no* caching rather than extending the window.
The two sets are kept separate on purpose and a test pins the separation.
One deliberate divergence from the historical payload, found by independent
review: that patch checked NO_1H_TIER_MODELS globally, ahead of the provider
gate. MiniMax on its own Anthropic-compatible endpoint is a separate and
genuinely cache-eligible route, and the global check regressed its configured
1h to 5m off the back of an opencode-go observation -- an unrelated-provider
change this repair must not make. Measured:
base effective_cache_ttl('1h', 'minimax', 'MiniMax-M2.5') -> '1h'
payload -> '5m'
here -> '1h'
Scope note on the evidence: the delayed-read run covered qwen3.8-max and
glm-5.2. The rule is keyed on the route, not the model, so the deployed
qwen3.7-plus is covered by it but has never itself been measured. This change
restores *sending* the requested 1h marker; it does not establish that the
provider honours 1h retention. Those stay separate claims, and the provider
labels every write `ephemeral_5m_input_tokens` whatever ttl was requested, so
only a delayed read past five minutes with no intervening call can settle it.
Tests: 11 new cases covering the deployed model, marker shape, precedence
against the generic clamp, cache eligibility surviving the repair, negative
controls for unrelated routes, provider case normalization, and a closed-set
audit of every marker-emitting call site. Ten mutations were applied to scratch
copies and each turned the suite red, including hoisting the generic clamp back
above the allowance, dropping opencode-go from ALIBABA_FAMILY_PROVIDERS,
un-nesting the model denial, and adding a new unclamped sender.
Known risk, not discharged here: this marker shape has never been sent on the
Go relay. #77217 records the sibling Zen relay returning HTTP 400 on an
unexpected marker shape, so field validation must check HTTP status before it
looks at any cache counter.

Security review on #97701 (unsupportedpastels) found and reproduced a
metadata-signature collision: atomic replacement that preserves size
and mtime (deployment tools that restore metadata; equal-length JSON)
rotates the private key under an IDENTICAL (path, mtime_ns, size)
signature, so the cache kept serving the old identity — exactly the
failure the PR set out to close.
The stat idiom is right for config caches (guards a parse, mtime
collisions are harmless). It is wrong for a credential cache (guards
an identity). The key is now (path, sha256(content)):
- _read_sa_file() reads the file ONCE per call, returning both the
bytes and the digest key; on a miss the credentials are built from
that same snapshot via from_service_account_info — closing the
stat->read TOCTOU the reviewer also flagged (key and credentials can
never describe different bytes).
- Read failure degrades to the bare-path key and the SDK's own file
read: byte-for-byte the pre-signature behavior.
- Cost: one read + sha256 of a ~2KB JSON per cache probe, noise next
to the OAuth token mint the cache exists to avoid.
New regression test per the review: equal-length content swap with
mtime restored and atomic replace — asserts a NEW cache key and a NEW
Credentials object (fails on the stat-keyed version, reproducing the
reviewer's cache_keys_equal=True). Fake google-auth harness gains
from_service_account_info.
Suite 10/10; ruff green.
The /simplify-code reviewer caught a real regression in the signature-
keyed cache commit: the ADC-failure fallback still compared
`cache_key == "__adc__"` (string), but keys are tuples now — the
comparison is always False, silently disabling the retry that picks up
a service-account file added after startup. The lead's pre-verification
had checked sentinel collision, failure-path pop, and TOCTOU, but
missed this consumer of the OLD key shape.
Guard now tests the actual condition (`not resolved_path` — this
attempt was ADC) instead of a key literal, so it can't rot again if
the key shape changes. New regression test drives the full path: ADC
raises, SA file appears on re-resolution, retry succeeds — fails on
the tuple-comparison version AND on any future key-shape change that
breaks the guard.
Pattern-D fix (stale cache after out-of-band change): the Vertex
credentials cache was keyed on the service-account file PATH alone, so
rotating the file on disk (key revoked and re-issued, new identity)
kept serving tokens minted from the OLD Credentials object for the
life of the process. Operators rotate compromised keys precisely when
they most need the new identity to take effect.
The cache key is now the file's (path, mtime_ns, size) signature — the
established idiom (agent/skill_utils.py:414, hermes_cli/config.py:3343,
and the shape #89792 applies to model overrides). Rotation bumps the
signature, forcing one re-read; the superseded entry for the same path
is evicted on insert so the cache stays bounded at one Credentials per
file. ADC keeps a stable sentinel key ("__adc__",) and its existing
expiry/refresh handling; a stat failure degrades to the bare-path key,
i.e. exactly the pre-signature behavior.
Tests (tests/agent/test_vertex_adapter.py):
- rotation invalidates: rewrite + mtime bump -> new key, new
Credentials object, old entry evicted (fails on main: main serves
the first identity's object after rotation)
- stat failure falls back to bare-path key, never raises
- ADC sentinel stable across None/empty resolved paths
Suite 8/8 green; ruff green.
LiteLLM OpenAI->Anthropic translation copies tool-message content parts
verbatim, so the envelope-layout part-level cache_control landed at
tool_result.content[0] - a placement the Anthropic Messages schema rejects
with a non-retryable HTTP 400 that killed the whole turn (any tool-using
cron/session on a LiteLLM-fronted Anthropic route).
New envelope_tool_part_cache_markers_supported() predicate (keyed on the
existing _is_litellm_route token matcher) threads a tool_part_markers flag
through build_prompt_cache_plan / apply_anthropic_cache_control and all
four decoration sites (main loop x2, destination replan, MoA). On LiteLLM
routes role:tool messages carry no markers and the breakpoint budget
reallocates to the nearest eligible message; OpenRouter/Nous Portal keep
the part-level form they honor, native Anthropic layout unchanged.
- Preserve streamed assistant text in Desktop UI when message.complete delivers empty text.
- Prevent destructive hydration in Desktop useMessageStream over rendered text on empty completion.
- Recover stream buffer in finalize_turn when final_response is empty on healthy turns.
- Unify in-place blank assistant repair, watermark clone resolution, non-blank concurrent winner adoption, and batch row appends into a single atomic guarded SessionDB transaction.
- Synchronize canonical committed content to live in-memory messages dicts and preserve all-or-nothing rollback semantics on persistence failure.
Squash of the three commits on PR #96768 (net diff is tests-only: the
mid-series production hunk in agent/transports/codex.py was reverted
within the PR after review). Pins the cache-scope isolation invariant
for hosts that mint one physical session per response, plus the
system-prompt write-path lifecycle under a per-response session (#96570).
Bedrock's cachePoint rules are per-model-family AND per-field. Amazon Nova
accepts a cachePoint block in `system` and `messages` but rejects it inside
`toolConfig.tools`, failing the whole request with
ValidationException: Malformed input request: #/toolConfig/tools/18:
extraneous key [cachePoint] is not permitted
so every tool-enabled Nova turn fails, with no retry path and no way for the
user to turn cache markers off (#97281).
The adapter decided placement from one static allowlist that answers only
"does this model cache at all", never "in which section". Any family whose
placement rules differ breaks 100% of turns until someone edits the table and
ships a release — the same maintenance trap the `_NON_TOOL_CALLING_PATTERNS`
comment already admits to ("if a model fails with a tool-related
ValidationException, add it here").
Make Bedrock's own verdict authoritative alongside the table: classify the
rejection by the JSON pointer AWS returns, drop the marker for that one
section, retry the request once, and remember the verdict for the rest of the
process so later turns are built clean. The other sections keep their cache
markers, so Nova still gets system/messages caching instead of losing prompt
caching wholesale. This mirrors the module's existing self-heal idiom
(`is_streaming_access_denied_error` → non-streaming `converse()`).
Applied at all four boto3 call sites: `call_converse`, `call_converse_stream`,
and both Bedrock dispatch sites in `chat_completion_helpers` (the streaming
one is the path in the report). A rejection with no marker to strip returns
None so the caller re-raises instead of looping.
