Kanban workers now scan the task body for local image paths and
http(s) image URLs and attach them to the worker's first user turn —
matching the CLI/gateway behaviour for inbound images. Before, a
user pasting `/home/me/screenshot.png` or `https://example.com/img.png`
into a kanban task description had it sent to the model as plain
text and the pixels were never seen.
How it works:
* agent/image_routing.py gains extract_image_refs(text) → (paths, urls)
that mirrors gateway/platforms/base.py:extract_local_files (absolute /
~-relative paths, image extensions only, ignores fenced/inline code).
* build_native_content_parts() accepts an optional image_urls= kwarg
and emits passthrough image_url parts for remote URLs alongside the
base64 data: URLs used for local paths.
* cli.py (single-query/quiet branch — the path every dispatcher-spawned
worker takes) detects HERMES_KANBAN_TASK, reads the task body via
kanban_db.get_task, runs extract_image_refs, and threads the results
into the existing image-routing decision (native vs text). Best-effort:
enrichment failures never block worker startup.
Tested:
* tests/agent/test_image_routing.py — 22 new tests for extract_image_refs
and URL pass-through in build_native_content_parts.
* tests/hermes_cli/test_kanban_worker_image_extraction.py — 10 new tests
driving real kanban_db round-trip (create task → read body → extract
refs → build parts).
* E2E: created a fake kanban task with a body referencing both a local
PNG and an https URL; verified the worker pipeline produces a
multimodal user turn with 1 text part + 2 image_url parts (data URL
for the local file, passthrough URL for the remote).
Adds an optional `messages` keyword to the `MemoryProvider.sync_turn`
contract so external/community memory plugins can receive the OpenAI-style
conversation message list for the completed turn — including assistant tool
calls and tool result content — not just the final assistant text.
Dispatch uses signature inspection (`_provider_sync_accepts_messages`): only
providers that declare a `messages` parameter (or `**kwargs`) receive it; all
existing in-tree providers keep their legacy text-only signature and are
called unchanged. No structured-trace envelope is added to core — providers
reconstruct whatever they need from the standard message list.
Also documents Memori as a standalone community memory provider.
Salvaged from #28065 — rebased onto current main.

* fix(redact): pass web URLs through unchanged
Magic-link checkout URLs, OAuth callbacks the agent is meant to follow,
and pre-signed share URLs were getting `?token=***` / `?code=***` /
`?signature=***` blanket-redacted by parameter NAME, which breaks any
skill that has to round-trip a URL through history (the model's tool
call arguments get sanitized before persistence — the live call fires
with the real URL, but the next turn sees `***`).
Joe Rinaldi Johnson hit this with a checkout-acceleration skill that
uses magic links in URLs.
Drops three call sites from `redact_sensitive_text`:
- `_redact_url_query_params` (was redacting `access_token`, `token`,
`api_key`, `code`, `signature`, `key`, `auth`, etc.)
- `_redact_url_userinfo` (was redacting `https://user:pass@host`)
- `_redact_http_request_target_query_params` (was redacting access-log
request targets like `"POST /hook?password=... HTTP/1.1"`)
The helpers themselves are kept in the module — still importable by
anything that wants to opt in explicitly.
Still redacted (unchanged):
- Vendor-prefix credential shapes (sk-, ghp_, AKIA, gAAAA, etc.)
anywhere they appear, including inside URLs — see the
`test_known_prefix_inside_url_still_redacted` case.
- JWTs (`eyJ...`)
- DB connection-string passwords (`postgres://admin:pw@host`) —
these are connection strings, not web URLs the agent navigates to.
- Authorization headers, ENV assignments, JSON `apiKey`/`token` fields,
Telegram bot tokens, private key blocks, Discord mentions, E.164
phone numbers, and form-urlencoded bodies (request bodies, not URLs).
Tests: replaces `TestUrlQueryParamRedaction` + `TestUrlUserinfoRedaction`
with `TestWebUrlsNotRedacted`, asserting representative URLs (OAuth
callback, magic link, S3 pre-signed, websocket, userinfo, access log)
pass through unchanged. Adds positive cases proving the prefix and DB
connstr nets still fire. 74 redact tests + 10 browser-exfil + 16 PII
redaction tests all pass.
* test(codex_app_server): drop URL-query assertion from stderr-tail redaction test
The test bundled (a) sk-live-* credential-prefix redaction with (b)
URL query-param redaction. (a) is still in effect via _PREFIX_RE;
(b) was the contract we just removed in the parent commit so the
'querysecret12345' assertion stopped holding. Keep the credential-shape
assertion, drop the URL-query one.
Send-message tool's local _URL_SECRET_QUERY_RE in tools/send_message_tool.py
is independent of agent/redact.py and unchanged — its tests
(test_top_level_send_failure_redacts_query_token,
test_http_error_redacts_access_token_in_exception_text) still pass.
Anthropic released Claude Opus 4.8 on 2026-05-27, available on
OpenRouter, Anthropic, Amazon Bedrock, and Claude Platform on AWS:
- https://openrouter.ai/anthropic/claude-opus-4.8
- https://openrouter.ai/anthropic/claude-opus-4.8-fast
The fast-mode variant is a separate model ID (anthropic/claude-opus-4.8-fast)
priced at 2x of the base model — a notable improvement over the 6x premium
on older Opus generations (4.6/4.7). It is NOT a `speed: "fast"` request
parameter like Opus 4.6; Anthropic's native fast-mode beta still only
covers Opus 4.6.
Changes:
hermes_cli/models.py
- Add anthropic/claude-opus-4.8 + anthropic/claude-opus-4.8-fast to
the OpenRouter fallback snapshot and the Nous Portal curated list
(live catalogs surface them automatically when reachable; the
fallback list matters when the manifest fetch fails).
- Add claude-opus-4-8 to the Anthropic-native picker list.
agent/model_metadata.py
- Register claude-opus-4-8 / claude-opus-4.8 in DEFAULT_CONTEXT_LENGTHS
with 1M tokens (matches 4.6/4.7).
agent/anthropic_adapter.py
- Extend _XHIGH_EFFORT_SUBSTRINGS, _ADAPTIVE_THINKING_SUBSTRINGS, and
_NO_SAMPLING_PARAMS_SUBSTRINGS with "4-8"/"4.8". 4.8 inherits the
Opus 4.7 API contract: adaptive thinking only, xhigh effort level
supported, sampling parameters (temperature/top_p/top_k) return 400.
- Add claude-opus-4-8 to _ANTHROPIC_OUTPUT_LIMITS (128k max output,
same as 4.7). Matches by substring so claude-opus-4-8-fast and
date-stamped variants resolve correctly.
agent/usage_pricing.py
- Add anthropic/claude-opus-4-8: $5/$25 per MTok input/output, $0.50
cache read, $6.25 cache write (same as 4.6/4.7).
- Add anthropic/claude-opus-4-8-fast: $10/$50 per MTok (2x), $1.00
cache read, $12.50 cache write. Per OpenRouter, the 2x premium is
the only differentiator from regular Opus 4.8.
- OpenRouter routes still pull pricing from the live /models API, so
no static OpenRouter entry is needed.
tests/agent/test_model_metadata.py
- Extend the Claude 4.6+ context-length tag list with 4.8/4-8.
website/static/api/model-catalog.json
- Regenerated via `python scripts/build_model_catalog.py` to pick up
the new entries in the OpenRouter and Nous Portal fallback lists.
E2E verification (isolated sys.path import against the worktree):
- _supports_adaptive_thinking, _supports_xhigh_effort, _forbids_sampling_params
all return True for claude-opus-4.8 and claude-opus-4.8-fast.
- _supports_fast_mode (the `speed: "fast"` request-parameter gate) stays
False for 4.8 — fast mode is a separate model ID on OpenRouter, not a
parameter Anthropic accepts on the base model.
- DEFAULT_CONTEXT_LENGTHS resolves 1M for both notations.
- resolve_billing_route + _lookup_official_docs_pricing resolve the
correct $5/$25 (regular) and $10/$50 (fast) pricing for both
dot-notation and dash-notation inputs.
- 4.7 and 4.6 regression: behavior unchanged.
Unit tests: 305 passed across tests/agent/test_usage_pricing.py,
test_model_metadata.py, tests/hermes_cli/test_model_catalog.py,
test_models.py, test_model_validation.py, test_models_dev_preferred_merge.py.
* fix(agent): fallback immediately on provider content-policy blocks
Provider safety-filter refusals (e.g. OpenAI Codex 'flagged for possible
cybersecurity risk', OpenAI moderation 'violates our usage policies',
Anthropic safety-system rejections, Azure content_filter) are
deterministic decisions about a specific prompt. Retrying the same
prompt up to api_max_retries times just reproduces the same refusal and
burns paid attempts before surfacing the generic 'API failed after 3
retries — <provider message>' to Telegram / cron with no indication that
the failure came from the model provider rather than Hermes itself.
Classify these as a new FailoverReason.content_policy_blocked
(non-retryable, should_fallback=True) and route them through the
existing is_client_error path so the loop:
- skips the 3x retry backoff
- activates a configured fallback model immediately
- emits a clear provider-safety message to the user (not the generic
'Non-retryable error (HTTP None)') and surfaces actionable guidance
when no fallback is configured (rephrase, narrow context, or set
fallback_model in hermes config)
- returns a final_response that explicitly tells the user this came
from the model provider, so gateway delivery is unambiguous and
cron last_status reflects the safety block rather than a vague
'agent reported failure'
Patterns are intentionally narrow — verbatim refusal phrasings keyed to
specific provider safety pipelines, not generic words like 'policy' or
'violation' that would collide with billing / format / auth errors.
Regression guards in test_18028_content_policy_blocked.py verify
billing 402s, generic 400s, and OpenRouter account-level
provider_policy_blocked remain distinct classifications.
Salvaged from #18164 onto current main (file restructure: loop logic
moved from run_agent.py to agent/conversation_loop.py, _emit_status →
_buffer_status), broadened patterns beyond the original OpenAI Codex
cybersecurity case to cover OpenAI moderation, Anthropic safety system,
and Azure content_filter; added user-actionable guidance and a clear
final_response so cron/gateway surfaces the policy block instead of a
generic non-retryable error, and added a regression-guard test module
mirroring the is_client_error predicate.
Addresses #18028.

* chore: add kchuang1015 to AUTHOR_MAP
---------
Co-authored-by: Kuan-Chieh Huang <kchuang1015@users.noreply.github.com>
Users report that the CLI/gateway floods them with confusing retry chatter
during transient failures: a single 429 can produce 10+ "Provider/Endpoint/
Retrying in 5s..." lines before the request eventually succeeds. The same
firehose hits Telegram, Discord, Slack, etc. via _emit_status.
This patch defers all retry/fallback/compression status messages until we
know the outcome:
- if the turn ultimately succeeds (any path: primary recovers, fallback
activates, compression unsticks the request), the buffer is silently
dropped — the user sees nothing.
- if every retry and fallback exhausts and the turn fails, the buffer
is flushed at the terminal-failure return so the user sees the full
retry trace alongside the final error.
Backend logging (agent.log) is unchanged — every emission site still
writes to logger.warning/info, so post-mortem diagnosis is intact.
## What changed
run_agent.py: four new methods on AIAgent:
_buffer_status(msg) — defer an _emit_status call
_buffer_vprint(msg) — defer a _vprint(force=True) line
_clear_status_buffer() — drop pending messages on success
_flush_status_buffer() — replay pending messages on terminal failure
agent/conversation_loop.py:
- converted ~30 mid-process emit/vprint sites in the retry, fallback,
compression, empty-response, and stream-watchdog paths to the buffered
helpers
- added _flush_status_buffer() at every terminal-failure return so users
still see the trace when it actually matters
- added _clear_status_buffer() at the "non-empty assistant content"
point (NOT at "API call returned bytes" — empty responses still loop
through the empty-retry path and would otherwise lose their trace
between iterations)
- silenced the two "(´;ω;`) oops, retrying..." / "(╥_╥) error,
retrying..." spinner final-frame messages — the spinner now stops
cleanly so retries leave no visible residue
agent/chat_completion_helpers.py: same conversion for codex TTFB / stale-
stream / fallback-activation status messages.
agent/stream_diag.py: _emit_stream_drop now buffers instead of emitting
directly.
## Tests
tests/run_agent/test_retry_status_buffer.py: 7 unit tests covering
accumulate→flush, clear-on-success, mixed kinds, empty-buffer no-op,
re-buffer after flush, exception swallowing.
Updated 3 existing tests that mocked _emit_status to also mock (or use)
_buffer_status:
- tests/run_agent/test_run_agent.py::test_empty_response_emits_status_for_gateway
- tests/run_agent/test_stream_drop_logging.py (2 tests)
- tests/agent/test_codex_ttfb_watchdog.py (TTFB hint test)
## Validation
Live test: hermes chat -q against an unreachable endpoint with no fallback
exhausts retries and prints the full trace at the end. Same flow against
a working endpoint prints zero retry chatter.
The web_crawl_tool() function was an orphan — no model schema registered
it, no skill or CLI command called it, and the agent had no way to invoke
it. PR #32608 proposed wiring it up as a model-callable tool; we've
decided not to expose crawl as a separate capability since web_search +
web_extract cover the use cases we want models to have.
Removed:
- tools/web_tools.py: web_crawl_tool() (~230 LOC)
- plugins/web/firecrawl/provider.py: supports_crawl() + crawl()
- plugins/web/tavily/provider.py: supports_crawl() + crawl()
- plugins/web/xai/provider.py: supports_crawl() override
- agent/web_search_provider.py: supports_crawl() + crawl() ABC methods
- agent/web_search_registry.py: get_active_crawl_provider() +
the 'crawl' branch in _resolve()
- agent/display.py: web_crawl tool-progress rendering
- hermes_cli/config.py: 'web_crawl' from TAVILY_API_KEY.tools
- tools/website_policy.py: stale comment reference
- Tests: removed TestWebCrawlTavily class, the two website-policy
web_crawl tests, the searxng/ddgs/brave-free crawl-error tests,
the integration test_web_crawl method, and the
test_unconfigured_crawl_emits_top_level_error test. Trimmed the
capability-flag parametrize list and the WebSearchProvider ABC
conformance tests.
- Docs: trimmed the Crawl column from capability tables in both EN
and zh-Hans, updated the developer-guide ABC table.
Net: 25 files, +115/-1067.
Closes#33762 (the schema-text bug only existed if #32608 landed).
Supersedes #32608.
api_messages is built once before the retry loop while the primary provider
is active. When a mid-conversation fallback switches to a require-side thinking
provider (DeepSeek/Kimi/MiMo), assistant turns built under a non-require primary
(e.g. Codex) go out without reasoning_content and the new provider rejects the
request with HTTP 400 ("reasoning_content must be passed back").
Re-apply the echo-back pad against the current provider immediately before
building the request kwargs. Idempotent and a no-op unless the active provider
enforces echo-back, so it covers all fallback paths without affecting normal or
reject-side operation.

Condenses the substance of PRs #16453, #17453, #16451, #17600, and #13373
into a minimal generic host contract that external context engine plugins
(e.g. hermes-lcm) need to integrate cleanly. Drops scaffolding that
duplicated existing infrastructure or had marginal value.
Five concrete changes:
1. `_transition_context_engine_session()` on AIAgent — generic lifecycle
helper that fires on_session_end → on_session_reset → on_session_start
→ optional carry_over_new_session_context. Engines implement only the
hooks they need; missing hooks are skipped. Built-in compressor keeps
its existing reset-only behavior because callers default to no
metadata. `reset_session_state()` now optionally accepts
previous_messages / old_session_id / carry_over_context and delegates
to the transition helper when provided. (#16453)
2. `conversation_id` passed to `on_session_start()` — both the
agent-init call site and the compression-boundary call site now
forward `self._gateway_session_key` so plugin engines have a stable
conversation identity that survives session_id rotation (compression
splits, /new, resume). The key already existed on AIAgent; it just
wasn't reaching engines. (#16453)
3. Canonical cache buckets forwarded to engines — the usage dict passed
to `update_from_response()` now includes input_tokens, output_tokens,
cache_read_tokens, cache_write_tokens, and reasoning_tokens on top of
the legacy prompt/completion/total keys. Engines can make decisions on
cache-hit ratios and reasoning costs instead of only aggregates. ABC
docstring updated. (#17453)
4. Plugin-registered context engines visible in the picker —
`_discover_context_engines()` in plugins_cmd.py now also includes
engines registered via `ctx.register_context_engine()` from plugin
manifests, deduplicating by name so repo-shipped descriptions win on
collision. (#16451)
5. `_EngineCollector.register_command()` — context engines using the
standard `register(ctx)` pattern can now expose slash commands (e.g.
`/lcm`). Routes to the global plugin command registry with the same
conflict-rejection policy regular plugins use (no shadowing built-ins,
no clobbering other plugins). Previously these calls hit a no-op and
the slash commands silently never appeared. (#17600)
Dropped from the original 5 PRs:
- Compression boundary signal (`boundary_reason="compression"`) from
#16453 — already on main at `agent/conversation_compression.py:412-424`,
landed via the bg-review extraction.
- `discover_plugins()` before fallback in run_agent.py from #16451 —
redundant: `get_plugin_context_engine()` already routes through
`_ensure_plugins_discovered()` which is idempotent.
- Runtime identity diagnostics method + helpers from #13373 (+251 LOC) —
operators can already read engine state via `engine.get_status()`;
the diagnostics view added marginal value relative to its surface area.
- The 553-LOC slash-command machinery from #17600 — replaced with a
20-LOC `register_command` method on the collector that reuses the
existing plugin command registry instead of building a parallel one.
Net: ~215 LOC of host-contract changes + 282 LOC of focused tests, vs
~1,176 LOC across the original 5 PRs.

Snapshot review_agent._session_messages before teardown so close() can
clean per-session state without dropping the user-visible
self-improvement summary. Adds two regressions:
- bg-review summarizer receives captured review-agent tool messages
after review_agent.close() runs
- context-compressor protected-head handoff rehydration populates
_previous_summary and keeps the old handoff out of newly summarized
turns
Salvaged from PR #26039 onto current main after agent/background_review.py
extraction. Original commit 63eaf6055; bg-review test updated to patch
the module-level summarize_background_review_actions in
agent.background_review instead of the now-forwarder
AIAgent._summarize_background_review_actions.
Salvages the transport-side fix from #32911 (@xxxigm). Closes#32892.
The openai SDK's responses.stream() / responses.parse() eagerly call
_make_tools(tools), which iterates tools without a None guard. Passing
tools=None raises TypeError: 'NoneType' object is not iterable before
any HTTP request is issued (openai==2.24.0).
PR #33042 already removed responses.stream() from our own Codex call
paths, so the specific iteration crash inside _make_tools is no longer
on the hot path. But the right API contract is to omit tools entirely
when there are no functions to expose — passing tools=None to the
backend is semantically wrong regardless of the SDK's iteration
behavior, and we'd hit it again on any future code path that hasn't
migrated off responses.stream().
This applies the transport-level part of @xxxigm's fix: move
'tools': response_tools into the if response_tools: branch so the
key is omitted when there are no tools, just like tool_choice and
parallel_tool_calls already are. Skips the run_agent.py-side
_strip_sdk_none_iterables helper from their PR — that path is now
obsolete because the SDK helper that needed defending is gone.
Tests
- tests/run_agent/test_codex_no_tools_nonetype.py: 6 tests trimmed
from @xxxigm's original 13-test file. Drops the obsolete tests for
_strip_sdk_none_iterables and _RecordingResponsesStream (helpers
that don't exist on main anymore), keeps the transport behavior
tests + the SDK contract sanity check that ensures we notice if
upstream ever fixes _make_tools(None).
- 6/6 passing locally.

Salvages the intent of #33136 (@Brixyy) onto current main. The original PR
was written against the pre-refactor monolithic run_agent.py and added a
top-level _is_nonretryable_local_validation_error() helper. Both target
functions have since been extracted to agent/conversation_loop.py:2869,
so the salvage applies the equivalent guard inline at that canonical
location rather than reintroducing the helper.
## Why
After #33042 made our own Codex consumer structurally immune to NoneType
crashes, third-party shims, mocked clients, and any future code path that
hasn't migrated could still surface TypeError: 'NoneType' object is not
iterable as a wire-shape mismatch. The agent loop's classifier currently
treats ALL TypeError as a local programming bug and aborts non-retryable
— users on stale Telegram/gateway turns saw bare "Non-retryable error
(HTTP None)" with no recovery.
This is a provider/SDK shape mismatch, not a local programming bug. The
retry/fallback path should run, not be short-circuited.
## What
agent/conversation_loop.py: extend is_local_validation_error to exclude
TypeErrors whose message matches the NoneType-not-iterable shape (case-
insensitive, both "NoneType" and "not iterable" must appear).
tests/run_agent/test_jsondecodeerror_retryable.py:
- update the mirror predicate to match the production check
- add TestNoneTypeNotIterableIsRetryable class with 3 tests (the basic
shape, message variants, unrelated TypeErrors still abort)
- add TestAgentLoopSourceHasNoneTypeCarveOut to enforce the source-level
invariant matches the test mirror
## Validation
tests/run_agent/test_jsondecodeerror_retryable.py +
tests/run_agent/test_31273_402_not_retried.py → 14/14 passing

Closes#33368.
`_CodexCompletionsAdapter.create()` iterates `final.output` from the
Codex Responses stream. The event-driven consumer (introduced in #33042)
always sets `final.output` to a list, so this shape can't come from our
own code path. But:
- Mocked clients in tests can return a typed Response with `output=None`
- Third-party shims / compatibility layers that bypass the consumer can
do the same
- A future code path that wraps a different consumer could regress
The old code `getattr(final, "output", [])` returns `None` (not the
default `[]`) when the attribute EXISTS but is `None`. Iterating
`None` then raises `TypeError: 'NoneType' object is not iterable` —
the exact error logged by title-generation when this fires.
Fix: `getattr(final, "output", None) or []` — single-line defensive
coerce. Cheap; zero risk.
Regression test asserts the auxiliary path handles a final whose
`.output` is `None` (via monkey-patched consumer) without raising and
returns the expected chat.completions-shaped response.
Reporter: @pavegrid-1 (issue #33368).
Closes#33163.
When _try_activate_fallback() switches from one provider to another (e.g.
openai-codex → openrouter), the credential pool still belongs to the
primary provider. This causes two compounding bugs:
1. The pool retains the primary's base_url. Downstream pool recovery
(rate_limit / billing / auth) calls _swap_credential() with a primary
entry which overwrites the agent's base_url back to the primary's
endpoint. Every fallback request then 404s against the wrong host.
2. Pool recovery acting on errors from the FALLBACK provider mutates the
PRIMARY's pool state (#33088 reported a related corruption pattern),
exhausting/rotating entries that have nothing to do with the failure.
Two layered fixes:
a) try_activate_fallback (agent/chat_completion_helpers.py): on fallback
activation, clear agent._credential_pool when the fallback provider
doesn't match the pool's provider. Pool is preserved when the fallback
shares the pool's provider (e.g. multiple openrouter entries).
b) recover_with_credential_pool (agent/agent_runtime_helpers.py):
defensive guard rejects any pool mutation when agent.provider doesn't
match pool.provider. Defense-in-depth — should never fire after (a)
is in place, but covers any future path that attaches a stale pool.
Salvaged from @zccyman's PR #33217. The original PR was written against
the pre-refactor monolithic run_agent.py; both target functions have
since been extracted to module-level helpers. Behavior is identical —
the guards live in the canonical extracted locations.
Tests
- New tests/run_agent/test_fallback_credential_isolation.py (7 tests
covering: fallback clears mismatched pool, fallback preserves matching
pool, recovery rejects mismatched pool, recovery accepts matching
pool, 429-from-z.ai-doesn't-exhaust-codex-pool, _client_kwargs
base_url survives pool clear, _swap_credential doesn't restore
primary URL after fallback).
- Cross-verified: 77/77 passing across fallback isolation tests +
agent/test_credential_pool.py — no regression.

Closes#33175.
switch_model() in agent/agent_runtime_helpers.py mutated agent.model and
agent.provider before rebuilding the client, with no try/except to restore
them on failure. If the rebuild raised (bad API key, network error,
build_anthropic_client failure, etc.) the agent was left with the new
model+provider name paired with the OLD client — producing HTTP 400s like
"claude-sonnet-4-6 is not supported on openai-codex" on the next turn.
Callers in cli.py, gateway/run.py, and tui_gateway/server.py already catch
the exception and warn the user, but the warning was misleading because
the swap had partially succeeded; the agent's state was torn.
Snapshot every mutated field before the swap, wrap the swap+rebuild block
in try/except, and restore the snapshot on failure before re-raising so
the caller's warning surfaces.
Reported by @amirariff91. Tests cover both branches (chat_completions and
anthropic_messages) and the cross-branch case (anthropic -> openai).
xAI's /v1/responses endpoint rejects service_tier with HTTP 400
"Argument not supported: service_tier" when users activate /fast mode.
Also add a safety-net strip_slash_enum call in _preflight_codex_api_kwargs
to catch any tool schemas that might slip through the caller-level
sanitization. xAI's Responses API grammar compiler rejects enum values
containing forward slashes (e.g. HuggingFace model IDs like
"Qwen/Qwen3.5-0.8B") with the opaque "Invalid arguments passed to the
model" error.
Fixes the root cause of "Invalid arguments passed to the model" errors
reported by xAI OAuth (SuperGrok) users.
reasoning.encrypted_content is sealed to the Responses endpoint that
minted it. When a session switches model providers mid-conversation —
say the user runs /model gpt-5.5 after several turns on grok-4.3, or
vice versa — the persisted codex_reasoning_items carry blobs the new
endpoint cannot decrypt, and every subsequent turn fails with HTTP 400
invalid_encrypted_content.
This is the cross-issuer prevention layer. Pairs with:
* PR #33035 — runtime recovery when the HTTP 400 fires anyway
* PR #33146 — prevention for transient rs_tmp_* items
Stamps each reasoning item with the issuer kind that minted it
(codex_backend / xai_responses / github_responses / other:<url>) at
normalize time, then drops items at replay time when the active
endpoint differs from the stamp. Unstamped (legacy) items pass
through for backwards compatibility.
Cherry-picked from @chaconne67's PR #31629. Conflict against current
main (#33035's replay_encrypted_reasoning parameter) resolved as
'keep both' — the two guards compose: replay_encrypted_reasoning=False
is the session-wide kill switch, current_issuer_kind is the per-item
filter that runs only when replay is still enabled.
* remove Vercel AI Gateway provider and Vercel Sandbox terminal backend
Both Vercel-hosted integrations are removed end-to-end. Users on the AI
Gateway should switch to OpenRouter or one of the other aggregators
(Nous Portal, Kilo Code). Users on the Vercel Sandbox backend should
switch to Docker, Modal, Daytona, or SSH.
What's removed:
- `plugins/model-providers/ai-gateway/` provider plugin
- `hermes_cli/vercel_auth.py` Vercel-Sandbox auth helper
- `tools/environments/vercel_sandbox.py` terminal backend
- `ai-gateway` provider wiring across auth, doctor, setup, models,
config, status, providers, main, web_server, model_normalize, dump
- `vercel_sandbox` backend wiring across terminal_tool, file_tools,
code_execution_tool, file_operations, approval, skills_tool,
environments/local, credential_files, lazy_deps, prompt_builder,
cli, gateway/run
- `AI_GATEWAY_BASE_URL` constant, `_AI_GATEWAY_HEADERS` auxiliary-client
header set, run_agent base-URL header/reasoning special-cases
- `[vercel]` pyproject extra and `vercel`/`vercel-workers` from uv.lock
- env vars: `AI_GATEWAY_API_KEY`, `AI_GATEWAY_BASE_URL`, `VERCEL_TOKEN`,
`VERCEL_PROJECT_ID`, `VERCEL_TEAM_ID`, `VERCEL_OIDC_TOKEN`,
`TERMINAL_VERCEL_RUNTIME`
- Tests: deletes test_ai_gateway_models.py and
test_vercel_sandbox_environment.py; scrubs references across 23
surviving test files (no entire tests deleted unless they were
dedicated to AI Gateway / Sandbox)
- Docs: provider tables, env-var reference, setup guides, security
notes, tool config, terminal-backend tables — English plus zh-Hans
i18n parity
- `hermes-agent` skill: provider table entry and remote-backend list
What stays (intentional):
- `popular-web-designs/templates/vercel.md` — CSS design reference,
unrelated to Vercel-the-AI-product
- `x-vercel-id` in `stream_diag.py` headers — generic Vercel CDN
response header, useful diag signal on any Vercel-hosted endpoint
- `vercel-labs/agent-browser` URL in browser config — lightpanda
browser project, different OSS effort
- `userStories.json` historical contributor entry mentioning Vercel
Sandbox — archive, not active docs
Validation:
- 1153 tests in the 22 targeted files pass (`scripts/run_tests.sh`)
- Full repo `py_compile` clean
- Live import of every touched module + invariant check (no
`ai-gateway` in `PROVIDER_REGISTRY`, no `_AI_GATEWAY_HEADERS`, no
`vercel_sandbox` in `_REMOTE_TERMINAL_BACKENDS`)
* test: convert profile-count check from change-detector to invariant
The hardcoded "== 34" assertion broke when ai-gateway was removed.
Per AGENTS.md change-detector-test guidance, assert the relationship
(registry count >= number of plugin dirs) instead of a literal count.
Counts shift when providers are added/removed; that's expected.
* refactor(codex): drop SDK responses.stream() helper; consume events directly
The OpenAI Python SDK's high-level `client.responses.stream(...)` helper
does post-hoc typed reconstruction from the terminal
`response.completed.response.output` field. The chatgpt.com Codex
backend has been observed (today, gpt-5.5) to ship `response.output =
null` on terminal frames, which crashes the SDK with `TypeError:
'NoneType' object is not iterable` mid-iteration.
Carlton's #32963 patched the symptom by wrapping the helper in
try/except and recovering from the same per-event accumulator the SDK
was supposed to populate. This PR removes the helper from the call
path entirely: we now use `client.responses.create(stream=True)` (raw
AsyncIterable of SSE events) and assemble the final response object
ourselves from `response.output_item.done` events as they arrive. The
terminal event's `output` field is never read for content. Same
strategy OpenClaw uses for the same backend.
This makes Hermes structurally immune to the bug class, not patched.
The next time OpenAI ships a shape change to chatgpt.com's terminal
frame, our consumer keeps working because it doesn't read that frame
for content — only for usage/status/id.
Changes
- `agent/codex_runtime.py`: new `_consume_codex_event_stream()` shared
consumer; `run_codex_stream()` uses `responses.create(stream=True)`;
`run_codex_create_stream_fallback()` collapses into a thin alias
since the primary path now does what the fallback used to do.
- `agent/auxiliary_client.py`: `_CodexCompletionsAdapter` uses the
same consumer; old null-output recovery helpers deleted as
unreferenced.
- Tests migrated: fixtures that mocked `responses.stream` now mock
`responses.create` returning a raw iterable. New regression test
asserts the auxiliary path returns streamed items even when the
terminal event's `output` is literally `null`.
Validation
- Live: tested against fresh OAuth on `chatgpt.com/backend-api/codex`
with `gpt-5.5` — response built correctly with `response.output=null`
on the terminal frame, all events consumed, usage/reasoning tokens
propagated.
- `tests/run_agent/test_run_agent_codex_responses.py` +
`tests/agent/test_auxiliary_client.py`: 242 passed.
* test+fix(codex): migrate streaming tests, raise on truncated streams
CI surfaced 10 test failures across tests/run_agent/test_streaming.py
and tests/run_agent/test_codex_xai_oauth_recovery.py — both files had
their own `responses.stream(...)` mocks I missed in the first sweep.
agent/codex_runtime.py: _consume_codex_event_stream() now raises
"Codex Responses stream did not emit a terminal response" when the
stream ends without any terminal frame AND no usable content. This
preserves the signal callers used to get from the SDK's high-level
helper, which they distinguished from "completed with empty body"
in error handling.
Tests migrated:
- test_streaming.py: text-delta callback, activity-touch, and
remote-protocol-error tests all switch from mocking responses.stream
to responses.create returning an iterable of events.
- test_codex_xai_oauth_recovery.py: prelude-error tests are recast as
wire-error-event tests (the new path raises _StreamErrorEvent
directly when the wire emits type=error, which is strictly better
than the old two-phase "SDK RuntimeError → retry → fallback"). The
retry-on-transport-error test moves from responses.stream side-effect
to responses.create side-effect.
Verified live against chatgpt.com Codex with gpt-5.5 — AIAgent.chat()
through the full codex_responses path returns correctly, 319/319
targeted tests passing.
* fix(codex-responses): gracefully recover from invalid_encrypted_content (salvage #10144)
When an OpenAI-compatible Responses API surface accepts an initial
request but later rejects the replayed `codex_reasoning_items`
encrypted blob with HTTP 400 `invalid_encrypted_content`, the
session previously got stuck retrying the same poisoned payload.
Recovery: classify the error as a dedicated FailoverReason, and on the
first hit disable encrypted reasoning replay for the rest of the
session, strip cached items from message history, and retry once.
Changes:
* error_classifier: add FailoverReason.invalid_encrypted_content
branch in _classify_400 (before context_overflow so the messages
that mention 'encrypted content … could not be verified' don't trip
context heuristics), in _classify_by_error_code, and extend
_extract_error_code to peek inside wrapped JSON in error.message and
ignore the bare '400' as a code.
* agent_init: initialize `_codex_reasoning_replay_enabled = True` on
every agent.
* run_agent: add AIAgent._disable_codex_reasoning_replay() helper
that flips the flag and pops cached items.
* codex_responses_adapter: thread a `replay_encrypted_reasoning`
kwarg through _chat_messages_to_responses_input so that when the
flag is False we don't replay codex_reasoning_items.
* transports/codex.py: read `replay_encrypted_reasoning` from params,
thread it into the adapter, and gate the
`include=['reasoning.encrypted_content']` request hint on it.
* chat_completion_helpers: pass the agent's replay flag through to
the transport.
* conversation_loop: in the retry loop, add an
invalid_encrypted_content recovery branch that fires once per
session, only when api_mode == codex_responses, only when replay is
still enabled, and only when at least one assistant message in
history actually carries cached reasoning items (otherwise the 400
has nothing to do with our cache and the normal retry path handles
it).
Tests:
* test_error_classifier: new wrapped-JSON _extract_error_code case;
new TestClassifyApiError cases proving the 400 is retryable with
no fallback, that the broad message match doesn't catch a generic
'parsed' message, and that the error code match is
case-insensitive.
* test_run_agent_codex_responses: end-to-end test of the recovery
branch firing once and disabling replay, plus a sibling test that
proves the branch does *not* fire (and the flag stays True) when
history has no cached reasoning items.
Salvages PR #10144 onto the post-refactor module layout
(error_classifier / codex_responses_adapter / transports/codex /
conversation_loop / agent_init) since the original diff was written
against the pre-refactor monolithic run_agent.py.

'hermes login' was removed (the command now just prints a deprecation
message and exits). The bundled hermes-agent SKILL.md, in-code error
messages, the tip rotation, the proxy adapters, and the docs site
still pointed agents and users at the dead command — so models loading
the skill kept running 'hermes login --provider openai-codex' and
getting a dead-end print.
Replacements use the canonical 'hermes auth add <provider>' surface
(or bare 'hermes auth' for the interactive manager).
Files:
- skills/autonomous-ai-agents/hermes-agent/SKILL.md (+ regenerated docs page)
- hermes_cli/tips.py (tip rotation)
- agent/google_oauth.py (gemini-cli error message)
- agent/conversation_loop.py (nous re-auth troubleshooting line)
- agent/credential_sources.py (docstring)
- hermes_cli/proxy/cli.py + hermes_cli/proxy/adapters/nous_portal.py (proxy auth hints)

- zh-Hans i18n mirrors for the above
'hermes logout' is still a live command and is left untouched.
The 'hermes login' stub in hermes_cli/auth.py:login_command() and
the cli-commands.md 'Deprecated' rows are intentionally kept as
the discoverable deprecation surface.
SubdirectoryHintTracker was scanning directories outside the active
working directory, allowing files like ~/.codex/AGENTS.md or
~/.claude/CLAUDE.md to be loaded and injected into the agent context.
This causes cross-agent context contamination and instruction mixup.
Add _is_ancestor_or_same() helper and a path boundary check in
_is_valid_subdir(): only directories within the working directory tree
(i.e. path.is_relative_to(working_dir)) are allowed.
Also add exist_ok=True to mkdir() calls in new tests to prevent
pytest-xdist race conditions when workers share the same tmp_path parent.
Tests added:
- test_outside_working_dir_rejected: verifies sibling dirs are blocked
- test_outside_working_dir_absolute_path_rejected: verifies ~/.codex paths blocked
- test_inside_workspace_subdir_allowed: verifies normal subdir access unaffected
- test_sibling_repo_not_loaded_via_ancestor_walk: ancestor walk stays within workspace
When the user picks 'Anthropic API key' at `hermes setup` (vs 'Claude
Pro/Max subscription'), `save_anthropic_api_key()` writes ANTHROPIC_API_KEY
to ~/.hermes/.env and zeros ANTHROPIC_TOKEN. That env-var pattern is the
user's explicit choice of auth method — API key, not OAuth.
But the anthropic credential pool's autodiscovery (_seed_from_singletons)
unconditionally read ~/.claude/.credentials.json from the Claude Code CLI
and any saved hermes_pkce creds, and added them to the SAME anthropic
pool as the user's API key. Two problems:
1. Even with the API key at higher priority, a 401/429 on the API key
would rotate the session onto an autodiscovered OAuth credential,
silently flipping the agent into the Claude Code masquerade
mid-conversation: 'You are Claude Code' system block, every tool
renamed to mcp_*, claude-cli User-Agent header.
2. Switching OAuth → API key at `hermes setup` cleared the env vars
but left previously-seeded OAuth entries dormant in auth.json,
where rotation could revive them.
The user picking the API-key path is explicitly opting OUT of the
masquerade. Mixing OAuth credentials into their pool defeats that
choice.
Fix: in `_seed_from_singletons` for provider='anthropic', detect the
API-key path (ANTHROPIC_API_KEY set in env, no OAuth env var set) and:
- Skip calling read_claude_code_credentials() and
read_hermes_oauth_credentials() entirely
- Prune any stale hermes_pkce / claude_code entries that may already
be in the on-disk pool
OAuth-path users (ANTHROPIC_TOKEN set) are unaffected — autodiscovery
continues to fire as before.
Tests: 3 new regression tests (api-key skips autodiscovery, api-key
prunes stale entries, oauth path still autodiscovers). Full file 70/70.
The outer 'except Exception' guard in run_conversation() captures
exceptions raised inside the agent loop (during streaming, tool
dispatch, message construction, etc.) and prints a one-line summary
to the screen. The traceback was only logged at DEBUG, so it never
landed in errors.log (WARNING+) and was lost.
For intermittent failures — the most important kind to debug — users
saw 'Error during OpenAI-compatible API call #N: <message>' on
screen with no way to recover the call site. Switching to
logger.exception() emits the full traceback at ERROR so it goes to
both agent.log and errors.log automatically.
This is a pure logging change; control flow is unchanged.
Hardens the context window against Brainworm-class promptware attacks
(see #496). Three changes:
1. tools/threat_patterns.py — single source of truth for injection/promptware
patterns. Replaces the duplicated pattern lists in prompt_builder.py and
memory_tool.py. Adds ~15 new Brainworm/C2 patterns (node registration,
heartbeat/beacon, pull tasking, anti-forensic disk avoidance, identity
override, known framework names). Three scopes — 'all' (narrow, classic
injection), 'context' (adds promptware/role-play, broader detection),
'strict' (adds persistence/SSH-backdoor patterns for user-mediated writes).
2. MemoryStore.load_from_disk() now scans entries at snapshot-build time.
Poisoned entries are replaced with [BLOCKED: ...] placeholders in the
frozen system-prompt snapshot. Live state keeps the original so the
user can still inspect + remove via memory(action=read/remove). Scan is
deterministic from disk bytes — prefix-cache invariant holds.
3. make_tool_result_message() wraps results from high-risk tools
(web_extract, web_search, browser_*, mcp_*) in
<untrusted_tool_result source="...">...</untrusted_tool_result>
delimiters with framing prose telling the model the content is data,
not instructions. Architectural defense against indirect injection
from poisoned web pages, GitHub issues, MCP responses — does NOT
regex-scan tool results (pattern arms race + per-iteration latency).
Multimodal content lists pass through unwrapped to preserve adapter
compatibility.
Pattern philosophy: anchor on C2-specific vocabulary or unambiguous attack
behavior, NOT on bossy English. Dropped patterns suggested in #496 that
would have tripped legitimate content: standalone 'you are obligated to',
'do not respond immediately', 'you must X' without a C2-verb anchor.
Validation:
- 257/257 targeted tests pass (test_threat_patterns + test_memory_tool +
test_tool_dispatch_helpers + test_prompt_builder)
- E2E run with real Brainworm payload: blocked from AGENTS.md context-file
path, blocked from MEMORY.md snapshot, wrapped in delimiters when
arriving via web_extract. Legitimate 'you must follow conventions'
phrasing not flagged.
Explicitly NOT in this PR (per #496 discussion):
- Per-tool-result regex scanning (pattern arms race)
- SessionBehaviorMonitor / polling-loop detection (wrong layer)
- Outbound network gating (Docker backend already covers this)
- security.context_scanning warn|block knob (current behavior is always
block-with-placeholder — there's no warn mode that makes sense)
Closes#496 for Phase 1 + the architectural delimiter piece of Phase 2.
Phase 3 stays in tracking issue territory.
xAI retired grok-4-1-fast. hermes_cli/models.py already removed it from
the static fallback in an earlier commit, but the context-length
metadata, the tests pinning those values, and the provider doc still
referenced the retired ID. Clean those up so retired model names stop
appearing in user-facing output.

After key #1 is marked exhausted the retry still called the API with key #1
due to env-var bias in _get_cached_client / resolve_api_key_provider_credentials.
Fix: peek the pool and pass the active entry's key as explicit_api_key.
Secondary: api_key_hint in mark_exhausted_and_rotate pins the correct entry
under concurrent CLI+gateway calls; _is_payment_error matches GoUsageLimitError;
extract_api_error_context parses "Resets in Xhr Ymin".
Closes#26145.
When the user interrupts the retry loop between two 429s (Ctrl-C in
interactive mode, /new, gateway disconnect), the local has_retried_429
flag dies with the recovery function. On the next user prompt the agent
restarts with has_retried_429=False, hits 429 on the exhausted credential,
sets the flag, returns 'retry once'. Repeat forever — the second 429 that
would trigger rotation is never reached, and healthy entries (priority>0
free/paid accounts) are never tried.
Fix: in recover_with_credential_pool's rate_limit branch, pre-check
pool.current().last_status before running the retry-once dance. If the
current entry is already STATUS_EXHAUSTED, rotate immediately. Uses
getattr() for the attribute read so existing tests with SimpleNamespace
mocks (which only set 'label') keep working.

Nous Portal is OAuth-only (auth_type=oauth_device_code, no API key path),
but the non-retryable-401 guidance branch only covered openai-codex and
xai-oauth. A Nous 401 fell through to the generic 'Your API key was
rejected... run hermes setup' message, which is wrong advice — the user
needs hermes auth add nous --type oauth, not an API key.
Also flag the case where the failing model slug ends in :free (OpenRouter
syntax) while provider is nous. Without that hint, users re-OAuth
successfully and then hit the same 401 on the next message because Nous
Portal doesn't carry the OpenRouter free-tier slug.
Reported by ashh — debug dump showed Nous device_code exhausted +
deepseek/deepseek-v4-flash:free as the model.
Aux callers (title generation, vision, session search, etc.) can reach
resolve_provider_client() without an explicit model when the user
picked their main provider via 'hermes model' and didn't bother
configuring a per-task auxiliary.<task>.model override. The
expectation in that case is universal: 'use my main model for side
tasks too.'
Before, the OAuth providers (xai-oauth, openai-codex) silently
returned (None, None) on an empty model — both lack a catalog default
because their accepted-model lists drift on the backend. That caused
_resolve_auto to drop to its Step-2 fallback chain (OpenRouter /
Nous / etc.), so aux tasks billed against the wrong subscription
without warning.
The fix is at the top of resolve_provider_client() — a single
3-step universal fallback that runs before any provider branch, so
no provider-specific empty-model guards are needed (now or for any
future provider we add):
1. caller-passed model (caller knew what they wanted)
2. provider's catalog default (cheap aux model, if registered)
3. user's main model from config.yaml
Behaviour by provider class:
- OAuth providers (xai-oauth, openai-codex) — no catalog default, so
step 3 applies. Title gen runs on grok-4.3 / gpt-5.4 against the
user's actual subscription instead of leaking to OpenRouter.
- API-key providers (anthropic, gemini, kimi-coding, etc.) — catalog
default wins at step 2, preserving the original 'cheap aux model'
behaviour. Anthropic users still get claude-haiku-4-5 for titles,
not opus.
- Explicit-model callers (auxiliary.<task>.model config, programmatic
callers) — caller wins at step 1, no surprise switching.
Salvaged from @wysie's PR #31845 which fixed the xai-oauth branch
specifically. The universal shape supersedes the per-branch fix
and covers openai-codex (same bug class) plus any future OAuth
providers.
4 new tests in TestResolveProviderClientUniversalModelFallback:
- empty_model_for_oauth_provider_falls_back_to_main_model
- empty_model_for_codex_also_uses_main_model
- empty_model_for_catalog_provider_uses_catalog_default
- explicit_model_takes_precedence_over_fallbacks

The chatgpt.com/backend-api/codex endpoint has an intermittent failure mode
where it accepts the connection but never emits a single stream event — the
socket just hangs. Direct sequential probing reproduces it (0 events, no HTTP
status), and a fresh reconnect then succeeds in ~2s. Today the only guard is
the wall-clock stale timeout in interruptible_api_call, so a dead-on-arrival
connection is held for the full stale window (90-900s depending on context /
config) before the retry loop can reconnect — minutes of wasted wall time per
stall, at a rate of ~20% of calls during affected windows.
Add a TTFB watchdog scoped to the codex_responses path:
- codex_runtime.run_codex_stream stamps agent._codex_stream_last_event_ts on
*every* stream event (not just output-text deltas), so reasoning-only and
tool-call-only turns are not mistaken for a stall.
- interruptible_api_call resets that marker before the worker starts and, while
it is still None, kills the connection once elapsed exceeds the TTFB cutoff
(default 45s, tunable via HERMES_CODEX_TTFB_TIMEOUT_SECONDS, 0 disables). The
raised TimeoutError flows through the existing retry path unchanged.
Once any event has arrived the stream is healthy and only the existing
wall-clock stale timeout applies, so legitimate long generations are never
interrupted. Gated to codex_responses; the chat_completions non-stream,
anthropic and bedrock branches have no first-event signal and are untouched.
Adds tests/agent/test_codex_ttfb_watchdog.py covering the stall kill, the
events-flowing pass-through, and the env-disable path.

* fix(streaming): route mid-tool-call partial-stream-stub through length continuation (#31998)
When a stream stalls mid-tool-call (e.g. a large write_file), the
partial-stream-stub recovery used finish_reason='stop' which caused the
conversation loop to treat the turn as complete, returning only the
warning text. When users said 'continue', the model retried the same
large tool call, hit the same stale timeout, and looped indefinitely.
Changes:
- chat_completion_helpers.py: change _stub_finish_reason from 'stop' to
'length' for mid-tool-call partials. The stub still has tool_calls=None
so no tool auto-executes — the model gets a fresh API call through the
existing length-continuation machinery (bounded to 3 retries).
Also attach _dropped_tool_names to the stub for downstream use.
- conversation_loop.py: add a third continuation prompt branch for
partial-stream-stubs with dropped tool calls. Instead of the generic
'continue where you left off' (which would retry the same large call),
tell the model to break the output into smaller tool calls (~8K
tokens each) to avoid stream timeouts.
- test_partial_stream_finish_reason.py: update existing test from
finish_reason='stop' to 'length', add _dropped_tool_names assertion,
add new test_dropped_tool_call_uses_chunking_prompt for the 3-way
prompt branching.
Safety: tool_calls=None is preserved on the stub, so the conversation
loop enters the text-continuation branch (line 1513), NOT the tool-call
execution branch (line 3246). No tool auto-executes. The model simply
gets another API call with targeted guidance.
* refactor: extract constants and continuation prompt helper
- Move magic strings to hermes_constants.py (PARTIAL_STREAM_STUB_ID,
FINISH_REASON_LENGTH)
- Extract _get_continuation_prompt() in conversation_loop.py — DRYs the
3-way prompt branching and lets tests import the real function
- Trim verbose inline comments in chat_completion_helpers.py
- Tests import constants + helper instead of duplicating logic

The ChatGPT Codex backend (chatgpt.com/backend-api/codex) has historically
silently dropped certain model requests: the connection is accepted but no
stream events are emitted and no error is raised. PR #31967 lowered the
implicit stale-call default from 300s to 90s so fallbacks kick in faster,
but users still see an opaque "No response from provider for 90s
(non-streaming, ...)" message that gives no path forward.
This patch adds a narrow heuristic — gpt-5.5 family on the Codex backend
via codex_responses api_mode — that substitutes the generic timeout
message with actionable text naming the gpt-5.4-codex workaround and
pointing at #21444 for symptom history.
Changes:
- run_agent.py — new ``AIAgent._codex_silent_hang_hint(model=...)`` method.
Returns ``None`` for any request that does not match all three guards
(codex_responses api_mode, openai-codex provider or chatgpt.com Codex
base URL, gpt-5.5-family model name with word-boundary regex anchoring
to avoid false-positives on e.g. ``gpt-5.50``).
- agent/chat_completion_helpers.py — the non-stream stale-call site
consults the hint via ``getattr(...)`` so the call site stays robust
if the helper is ever removed or stubbed in tests. Hint is appended to
both the ``_emit_status`` warning and the ``TimeoutError`` message so
the user sees it in their terminal AND it lands in any retry-loop
diagnostics.
- tests/run_agent/test_codex_silent_hang_hint.py — 10 regression tests
covering positive cases (bare gpt-5.5, vendor-prefixed openai/gpt-5.5,
gpt-5.5-codex SKU, model=None fallback to self.model) and negative
cases (gpt-5.4-codex workaround, gpt-5.50 false-positive guard,
non-codex api_mode, non-codex provider, empty/None model, unrelated
models on Codex).
Does NOT fix the backend-side issue (that's an upstream OpenAI/ChatGPT
problem we cannot patch from here). Only converts an opaque timeout into
text that names the workaround so users do not have to dig through logs
or wait for a forum post to learn what to do.
Closes#22046
get_read_block_error() only blocked internal Hermes cache files but
allowed reading project-local secret-bearing environment files (.env,

Add a basename deny set for common secret-bearing .env variants.
.env.example remains readable as documentation.

* perf(bitwarden): persist secret-fetch cache across CLI invocations
Every `hermes` invocation paid a ~380ms tax for `bws secret list` to
Bitwarden Secrets Manager because the existing cache was in-process only.
Back-to-back `hermes chat -q`, gateway-spawned agents, and cron-launched
runs all re-fetched.
Adds a disk-persisted L2 cache at `<hermes_home>/cache/bws_cache.json`
(mode 0600, never contains the access token — only the SHA-256
fingerprint prefix). Same TTL as the in-process cache. Read on miss,
write on bws success, ignored on key mismatch / corruption / expiry.
Measured on a startup profile:
load_hermes_dotenv() cold: 372ms → warm (disk cache hit): 20ms
End-to-end `hermes --version` cold→warm: 666ms → ~295ms.

Hermes now wins head-to-head on 6/11 tasks vs codex (was 4/11 before).
The remaining ~0.6s single-turn delta is mostly Python's own import
cost in hermes_cli.main, which is a separate optimization.
* perf(cli): lazy-load model catalog + dedupe config.yaml reads at startup
Two import-time wins on top of the bws disk-cache fix:
1. Lazy-load `hermes_cli.models._PROVIDER_MODELS` via PEP 562
module-level `__getattr__`. The catalog is ~55ms of work that was
eagerly imported on every CLI invocation (line 4557 `if not
_is_termux_startup_environment(): from hermes_cli.models import
_PROVIDER_MODELS`). Audit showed every internal call site already
does its own function-local import; only test code reads
`hermes_cli.main._PROVIDER_MODELS` as a module attribute, and
__getattr__ keeps that working transparently. First access triggers
the import once and caches the result on the module via
`globals()[name] = ...`, so subsequent reads are dict lookups.
2. Dedupe the double config.yaml read in the top-of-module bootstrap.
Previously: one raw yaml.safe_load for the `security.redact_secrets`
bridge, then a separate full `load_config()` (with deep-merge) for
`network.force_ipv4`. Both keys come from the same file. Merged
into one raw yaml load.
Combined with the bws cache fix in the previous commit:
hermes --version wall time:
original (cold): 666 ms
after bws fix (warm): 295 ms
after lazy-load + dedupe: 228 ms (-67 ms additional, -66% from original)
Tests:
- tests/hermes_cli/test_api_key_providers.py: 173/173 pass
(lazy __getattr__ correctly handles
`from hermes_cli.main import _PROVIDER_MODELS`)
- tests/test_ipv4_preference.py + tests/hermes_cli/test_redact_config_bridge.py +
tests/agent/test_redact.py: 93/93 pass (dedupe preserves both bridges)
- tests/test_bitwarden_secrets.py + env_loader tests: 49/49 pass
Codex / Responses-API requests had three latent timeout bugs that combined
into the long silent hangs reported on #21444:
1. The non-stream stale-call detector estimated context tokens from
``api_kwargs["messages"]`` only. Codex / Responses-API payloads carry
their conversational load in ``input`` (with ``instructions`` and
``tools``), so every Codex turn logged ``context=~0 tokens`` and the
detector never applied its >50k / >100k tier bumps.
2. ``providers.<id>.request_timeout_seconds`` was silently dropped on the
main Codex path. The chat_completions path and the auxiliary Codex
adapter both forwarded it; the main path skipped it through three
places (``build_api_kwargs``, ``ResponsesApiTransport.build_kwargs``,
``_preflight_codex_api_kwargs``).
3. The streaming stale detector had the same payload-shape bug for
``codex_responses`` requests, which route through the non-streaming
detector (it's the path that emits the user-facing
"No response from provider for 300s (non-streaming, ...)" warning that
reporters keep pasting).
This commit:
- Adds ``estimate_request_context_tokens`` in ``chat_completion_helpers``,
used by both the non-stream and stream detectors. Handles ``messages``
(Chat Completions), ``input + instructions + tools`` (Responses API),
bare lists, and an unknown-dict fallback.
- Forwards ``timeout`` through ``ResponsesApiTransport.build_kwargs``
and ``_preflight_codex_api_kwargs`` (with guards against
zero/negative/inf/bool values), and wires
``_resolved_api_call_timeout()`` into the Codex branch of
``build_api_kwargs``.
- Lowers the implicit non-stream stale defaults so fallback providers
kick in faster when upstream stalls:
* base 300s -> 90s
* >50k 450s -> 150s
* >100k 600s -> 240s
These only apply when the user has *not* set
``providers.<id>.stale_timeout_seconds`` or
``HERMES_API_CALL_STALE_TIMEOUT``. Explicit config still wins.
- Adds regression tests for the estimator shapes, the new defaults, the
context-tier scaling, transport timeout pass-through, and preflight
timeout pass-through / rejection of invalid values.

Follow-up to @someaka's fix.
Polish:
- Drop the redundant `_preflight_tokens >= threshold_tokens` clause.
`should_compress(tokens)` already short-circuits when tokens < threshold,
so the explicit comparison was dead code on the True branch.
Tests:
- Preflight: pin that should_compress() is called (anti-thrash has a vote).
Mocks should_compress to return False even with tokens past the raw
threshold and asserts no compression runs — exact bug shape from #29335.
- Gateway: AST scan of gateway/run.py asserts every
`session_entry.session_id = ...` assignment is followed by a
`session_store._save()` call within the same block. Three sites mutate
the session_id after compression; all three must persist or the next
turn loads the pre-compression transcript and re-loops. Empirically
verified the test catches the bug (drops the new _save() line → red).
AUTHOR_MAP:
- Map ed@bebop.crew -> someaka so the salvaged commit resolves to
@someaka in release notes.
Three compounding root causes:
A) run_conversation() result dict missing session_id — gateway's
dead-code guard at gateway/run.py:8700 never triggers
B) preflight compression bypasses should_compress() anti-thrashing —
re-triggers every turn when tool schemas dominate token budget
C) gateway updates session_entry.session_id in memory but doesn't
persist via session_store._save()
Fixes: #29335
