teknium1 471d8a427a ci(plugin-catalog): probe stars only from the scheduled skills-index run, in one GraphQL request
Aligns the star ranking with the rule the skills index already follows:
GitHub is consulted only by the twice-daily skills-index.yml schedule, whose
artifact every docs deploy reuses. deploy-site.yml now runs
fetch-plugin-stars.py without --probe (reuse-only: artifact → live site copy →
disk → empty) and cannot call the API at all, so a same-day merge train adds
zero requests regardless of cache age.

The probe itself collapses from one REST call per repo (~26 today, growing
with the catalog) to a single GraphQL query with aliased repository fields,
so the scheduled run costs one request no matter how big the catalog gets. A
failed probe (rate limit, renamed repo, bad token) keeps the previous counts.

teknium1 e7794124da fix(skills-index): bound ClawHub owner enrichment so the scheduled index build finishes
Every scheduled skills-index.yml run since 2026-07-20 was cancelled at the 15-minute
job timeout, so the live skills-index.json has been frozen at that date and every
`hermes skills search` fell through to live GitHub API calls (~500 inspect requests per
cold search, against a 60/hr unauthenticated budget). The freshness watchdog has been
appending to #66616 four times a day since.

Root cause: enrich_owners() walks every ClawHub skill's detail endpoint (~2s each) to
fetch an owner handle for the "View source" link. The catalog grew from ~50k to 78k
skills, so even at 30 workers that phase alone runs over an hour; nothing bounded it.

- enrich_owners() gains budget_seconds: on expiry it stops and ships the remainder
  without an owner (the link is a nicety; the index is not).
- build_skills_index.py passes an 8-minute budget.
- skills-index.yml build job timeout 15 -> 50 min to cover the measured critical path
  (clawhub walk ~14 min || github taps ~8 min, skills.sh resolve ~6 min, enrichment 8 min).

kshitij f51aa6a9b5 fix(ci): repair red main — busy-mode test + missing checkout in skills-index workflows
Three separate reds on main. Two are fixed here; the third needs no code.

1. tests/gateway/test_multiplex_busy_input_mode.py (blocks every merge)

Fails "Python tests / Run tests slice 5/12" and therefore "All required
checks pass". Semantic merge conflict between two PRs merged ~1h apart:

  a31be480 fix(gateway): respect routed profile busy modes             (added the test)
  c8f235a1 feat(gateway): allow selective multiplex profile serving    (added the gate)

c8f235a1 taught _profile_name_for_source to reject a route whose target
profile is not in the served set (profiles_to_serve). Each PR was green on
its own base; neither ran against the other's merge result.

The test asserts a route to profile "research" resolves to that profile's
busy mode, but never patches profiles_to_serve — so it reads the runner's
REAL on-disk profiles. "research" is not among them, the route is rejected
before the busy-mode snapshot is consulted, and the assertion gets the
gateway default:

  WARNING gateway.run: Rejecting profile route 'research-chat':
                       target profile 'research' is not served
  AssertionError: assert 'interrupt' == 'steer'

Patch profiles_to_serve for the assertion — the same seam every sibling
test in tests/gateway/test_profile_resolution.py already patches
(test_route_inside_allowlist_resolves, test_route_outside_allowlist_rejects).

This also removes an ambient-state dependency: the test previously passed
or failed based on which profiles happened to exist on the machine running
it. Verified passing under an empty HERMES_HOME.

Test-only. The serving gate from c8f235a1 is correct and left intact.

2. Skills-index workflows: local action used without actions/checkout

check-freshness has failed on all 12 of its last 12 scheduled runs:

  ##[error]Can't find 'action.yml', 'action.yaml' or 'Dockerfile' under
  '.../.github/actions/get-app-token'. Did you forget to run
  actions/checkout before running your local action?

./.github/actions/get-app-token is a LOCAL composite action and cannot
resolve without the repo on disk. skills-index-freshness.yml had no
checkout step at all. The step is gated on `status != 'ok'`, so the
watchdog broke exactly when it was supposed to file its issue — the live
index is currently 521.4h stale (limit 26h) and nobody was told.

An audit of all workflows for this bug class found one more instance:
skills-index.yml's `trigger-deploy` job, which re-triggers the docs deploy
so a refreshed index reaches the live site. Its sibling `build-index` job
checks out; this one did not. That is plausibly why the index went stale
in the first place. Both are fixed; the audit now reports zero remaining
jobs that use a local action without a prior checkout.

Pinned to the same actions/checkout SHA used by the other 35 call sites.

3. "Publish inline E2E evidence" — no fix needed

Failed once at 13:33Z on a transient TLS error reaching api.github.com
("certificate is not valid for any names") while installing a gh
extension. The last 25 runs of that workflow are 25/25 success. Infra
blip, not a code defect.

ethernet 957ea640de fix(ci): publish inline E2E evidence (#69699)
* fix(ci): publish inline E2E evidence

Upload bounded screenshot evidence from E2E, then publish validated images
from a trusted workflow_run job to commit-pinned branches in the evidence repo.

Wait briefly for the live CI review comment marker before publishing, so
GitHub's read-after-write delay cannot leave an orphaned evidence branch.

* fix(ci): isolate privileged credentials from PR jobs

Keep App private keys and Docker Hub credentials out of PR-controlled
workflows. Use protected environments for trusted publishing and a public
repository variable for the App client ID.

* fix(ci): attach E2E evidence with restricted bot session

Replace the App-backed evidence repository publisher with gh-image uploads
from a dedicated bot session in the gh-image environment.

* fix(ci): publish validated E2E evidence from forks

Let the trusted default-branch publisher handle bounded, validated evidence
artifacts from fork PR CI without checking out or executing fork code.

ethernet 1f76bdc5b2 fix(ci): pass App secrets as inputs to composite action
Composite actions cannot access the secrets context — the runner's
template engine rejects secrets.* references at load time with
'Unrecognized named-value: secrets'.

Move APP_ID and APP_PRIVATE_KEY from direct secrets.* references inside
the composite action to inputs passed by each calling workflow. The
fallback logic (GITHUB_TOKEN when APP_ID is empty, for fork PRs) stays
in the composite action's check step.

ethernet 7a69b82ad4 ci: migrate AUTOFIX_BOT_PAT to GitHub App token
Replace the long-lived fine-grained PAT (AUTOFIX_BOT_PAT) with short-lived
(1-hour) installation access tokens minted via a new get-app-token composite
action wrapping actions/create-github-app-token@v3.2.0.

The PAT was used in 13 spots across 8 workflow files for gh CLI / GitHub API
calls. The per-repo GITHUB_TOKEN (1,000 req/hr) was getting rate-limited when
multiple workflows fire concurrently (deploy-site, skills-index, ci-timings,
supply-chain-audit, js-autofix). App installation tokens get 5,000 req/hr
per installation and are scoped to the App's permissions, not a user account.

New composite action: .github/actions/get-app-token/
  - Wraps actions/create-github-app-token@bcd2ba49 (v3.2.0, SHA-pinned)
  - Reads APP_ID + APP_PRIVATE_KEY repo secrets
  - Outputs a 1hr installation token via steps.app-token.outputs.token

Requires two new repo secrets (set after creating the GitHub App):
  - APP_ID: the App's numeric ID
  - APP_PRIVATE_KEY: the PEM private key

App installation permissions needed:
  contents: write    (js-autofix push, pypi release upload)
  pull-requests: write (js-autofix PR create/merge, supply-chain comment)
  issues: write       (skills-index-freshness issue creation)
  actions: write     (skills-index workflow trigger)
  workflows: write   (skills-index triggers deploy-site.yml)

The AUTOFIX_BOT_PAT secret can be deleted once CI passes on this PR.
The comment in js-autofix.yml noting that PAT pushes trigger downstream
workflows is updated — App tokens have the same property (they are not
GITHUB_TOKEN), so the concurrency-cancel loop logic is unchanged.

Teknium 597615ade4 fix(ci): make tests, workflows, and attribution reliable under load (#66373)
* feat(attribution): conflict-free contributor mappings via contributors/emails/ directory

The AUTHOR_MAP dict in scripts/release.py was a merge-conflict magnet:
every concurrent salvage PR appended entries to the same lines of the
same file, so parallel PRs re-conflicted on every merge to main.

New system: one file per email under contributors/emails/ — filename is
the commit-author email, first non-comment line is the GitHub login.
File additions never conflict, so any number of PRs can add mappings
concurrently.

- scripts/release.py: AUTHOR_MAP is now LEGACY_AUTHOR_MAP (frozen)
  merged with the directory at import time (directory wins). All
  existing consumers (resolve_author, contributor_audit.py) unchanged.
- scripts/add_contributor.py: idempotent CLI to add a mapping; refuses
  conflicting reassignments (incl. against the legacy map), validates
  email/login shapes.
- contributor-check.yml: attribution gate now accepts a mapping file OR
  a legacy entry; failure message prints the exact add_contributor
  command. Also auto-resolves bare <login>@users.noreply.github.com
  emails is intentionally NOT added (kept id+login form only, matching
  previous behavior).
- contributor_audit.py: guidance now points at add_contributor.py.
- tests/scripts/test_contributor_map.py: 12 tests covering loader,
  merge precedence, CLI idempotency/conflict/validation, subprocess E2E.

* feat(ci): one-shot per-file flake retry in the parallel test runner

A failing test FILE is re-run once in a fresh subprocess. Pass-on-retry
counts as green but is loudly reported in a '⚠ FLAKY' summary section
(with both attempts' output preserved) so the flake gets fixed instead
of eating a full-run rerun. Deterministic failures fail both attempts —
regressions cannot be laundered green.

- --file-retries N / HERMES_TEST_FILE_RETRIES (default 1, 0 disables)
- E2E verified: simulated first-run-fail flake goes green with banner;
  deterministic failure still exits 1; retries=0 restores old behavior.

This converts the dominant CI failure mode (one timing-sensitive test
flaking a 4600-test shard, requiring a manual 10-minute rerun and an
agent triage loop) into a self-healing retry that costs one file's
runtime.

* test(approval): loosen wall-clock perf bounds 0.15s -> 2.0s

These guard against catastrophic regex backtracking (seconds-to-minutes
class), but 0.15s is within scheduler-stall noise on loaded shared CI
runners — test_max_accepted_separator_free_input_is_fast failed a CI
shard this week on runner load alone. 2.0s still catches the regression
class with zero flake surface.

* fix(ci): job timeouts everywhere + retries on all network installs

Reliability pass over every workflow:
- timeout-minutes on all 21 jobs that lacked one (a hung job previously
  burned the 6-hour default runner budget)
- ./.github/actions/retry wrapped around every network-fetching install
  that lacked it: pip installs (deploy-site, skills-index), npm ci
  (deploy-site website, upload_to_pypi web + ui-tui), uv sync (docker
  test deps). Deterministic build steps (npm run build) deliberately
  NOT retried — split into separate steps so a real build failure fails
  fast instead of retrying 3x.

* docs(agents): document the file-retry flake policy

* fix(ci): curl retries on deploy hook + skills-index probe

* fix(ci): kill the remaining transient-failure classes in workflows + Dockerfile

From the workflow reliability audit:
- tests.yml: duration-cache restore had NO restore-keys while saves use
  run_id-suffixed keys — the cache never matched once, so LPT slicing
  always ran blind and unbalanced slices pushed heavy files toward the
  per-file timeout. One-line restore-keys fixes slice balancing.
- Label gates (lint ci-reviewed, supply-chain mcp-catalog-reviewed):
  'gh pr view || true' turned an API blip into 'label absent' → false
  BLOCKING failure. Now 3x retry, and API failure is reported as an API
  failure instead of a missing label.
- detect-changes action: compare API retried before failing open (was
  silently running all lanes on any blip).
- uv-lockfile-check: 'uv lock --check' resolves against PyPI — retried
  so registry blips don't read as 'lockfile stale'.
- docker.yml merge job: imagetools create retried (Docker Hub eventual
  consistency on just-pushed digests).
- Dockerfile: apt-get Acquire::Retries=3; s6-overlay ADDs converted to
  curl --retry 3 (ADD cannot retry; checksums still enforced); npm
  --fetch-retries=5; playwright chromium fetch retried 3x.
- Advisory artifact uploads (per-slice durations, ci-timings report)
  get continue-on-error so an artifact-service blip can't fail a green
  test slice.

* fix(tests): kill the two root-cause flakes — leaking pre-warm timer + env-dependent provider list

- test_tui_gateway_server.py: session.create / non-eager session.resume
  arm a 50ms threading.Timer (_schedule_agent_build) that outlives its
  test and fires into the NEXT test's _make_agent mock, racily
  corrupting captured state (the recurring session_resume shard
  failures). Replaced the per-test whack-a-mole stub with a module-wide
  autouse fixture; the 3 worker-lifecycle tests that genuinely need the
  deferred build opt back in via @pytest.mark.real_agent_prewarm (new
  marker in pyproject).
- test_api_key_providers.py: PROVIDER_ENV_VARS is now derived from the
  live PROVIDER_REGISTRY instead of a hand-list that had drifted
  (missing HF_TOKEN / DEEPINFRA_API_KEY) — resolve_provider('auto')
  tests failed on any machine with HF_TOKEN exported. E2E-verified with
  HF_TOKEN/DEEPINFRA_API_KEY set: 42/42 pass.

* test: de-flake 30 timing-sensitive test files for loaded CI runners

Root-cause fixes from the flake audit (session-DB mining + repo sweep):

Event-based sync instead of sleep-sync:
- title_generator: mock sets threading.Event, wait(10) replaces
  sleep(0.3) hoping the daemon thread got scheduled
- docker zombie_reaping / profile_gateway: poll-for-state helpers
  replace fixed 1-3s sleeps (s6 transitions + SIGCHLD reaping are async)
- process_registry tree test: select()-bounded readline replaces an
  unbounded blocking read (parent wedge now fails THIS test with a clear
  message instead of an opaque rc=124 file kill); SIGTERM grace 1s->2s
  (the 1s partition window mid-interpreter-startup is how a child PID
  escaped the live-system guard in CI)

Timeout raises (loaded 8-way-sliced runners see ~5s scheduling floors;
all of these complete in ms-to-1s when healthy so the raises cost
nothing on green runs):
- subprocess/thread waits <= 2s raised to 10-15s across mcp_tool,
  mcp_circuit_breaker, mcp_reconnect_retry_reset, mcp_parked_self_probe,
  mcp_cancelled_error_propagation, registry, clarify_gateway, interrupt,
  voice_cli_integration, docker_environment, session_store_lock_io,
  planned_stop_watcher, cli_interrupt_subagent, thread_scoped_output
  (joins now also assert not is_alive() so stragglers fail loudly)
- wall-clock discrimination ceilings loosened where the guarded hang is
  10x larger: local_background_child_hang 4s->10s, interrupt_cleanup
  setup 5s->20s + pgid-exit 30s->60s, mcp_stability grandchild spinup
  5s->15s, protocol/gil-starvation fast-handler 0.5s->2s,
  iso_certify_seam 1.5s->5s, wait_for_mcp_discovery 0.1s->1s
- narrow assertion windows widened: honcho first-turn wait 0.4..0.65 ->
  0.25..2.0 (property is bounded-not-hung, not an exact wall-clock);
  compression fork-lock TTL 1s->3s (12 refresh chances per lease);
  compression-lock expiry margins symmetric (ttl 0.05->0.5, sleep 1.0)
- telegram hung-DNS bound 1.0->1.4 (fake hang is 1.5s — must stay under)

* fix(tests): repair indentation from de-flake batch edit

* fix(tests): harden env isolation and replace remaining sleep-sync races

The full 42k-test run and complete npm check surfaced three more classes:

- Environment isolation: local ~/.honcho defaultHost and SSH_* variables
  leaked into Python/TUI tests. Pin the default Honcho host in the
  hermetic fixture, isolate the one fallback test from ~/.honcho, and
  blank SSH_* around terminalSetup tests. This flipped 20 false failures
  back to deterministic behavior on developer machines.
- Background-thread sleep-sync: Honcho async writer tests patched
  time.sleep globally, then busy-polled with that same mocked sleep. Under
  full-suite load the poller could starve the writer. Each test now waits
  on an Event emitted by the exact flush/retry transition; 30/30 passed
  under 15-way contention.
- Desktop streaming: the test slept 80ms and assumed a 500ms timer could
  not fire before its assertion. A loaded runner descheduled the test for
  >500ms and both chunks arrived. Producer controls now gate second-chunk
  and completion transitions explicitly.

Also make file-retry observability complete: a self-healed flaky file now
prints BOTH attempts' full output in the FLAKY summary. Two behavioral
runner tests prove pass-on-retry is green+loud+traceback-preserving, while
a deterministic failure remains red.

* refactor(ci): use gh bot pat, better retries

refactor(ci): use retry action for PR label fetch
the retry action now captures stdout as a step output, so it can serve
double duty: retry + output capture for commands like 'gh pr view' whose
result must be consumed by later steps.

Retry action gains:
- 'stdout' output (heredoc-delimited to preserve newlines)
- tee to temp file so stdout still streams to the job log
- step id 'retry' for output reference

Both lint.yml and supply-chain-audit.yml now use the retry action
directly with 'command: gh pr view ...' and read
steps.<id>.outputs.stdout.

ci: use AUTOFIX_BOT_PAT for all gh CLI / GitHub API auth

Replace secrets.GITHUB_TOKEN and github.token with
secrets.AUTOFIX_BOT_PAT across all workflows and composite actions
that use the gh CLI or GitHub API. The PAT has consistent permissions
across fork PRs (where GITHUB_TOKEN is read-only), avoids API rate
limit sharing with the default token, and is already used by
js-autofix.yml for the same reasons.

19 sites swapped across 9 files:
- lint.yml (3): label fetch, comment post/edit, comment update
- supply-chain-audit.yml (5): scan, critical comment, unbounded dep
  comment, label fetch, mcp-catalog comment
- lockfile-diff.yml (1): PR comment post/update
- skills-index-freshness.yml (1): issue creation on degraded probe
- skills-index.yml (2): index build, trigger deploy workflow
- upload_to_pypi.yml (2): release view poll, release upload
- ci.yml (1): timings report
- deploy-site.yml (2): skills index crawl
- detect-changes/action.yml (1): compare API call

Teknium 4373e802a1 fix(docs): reuse healthy skills index during Pages deploys (#45616) 2026-06-13 06:46:07 -07:00
Teknium cea87d9139 fix(skills-hub): show every catalog source on /docs/skills (skills.sh, ClawHub, browse.sh, OpenAI, …) (#32336)
The Skills Hub page was stuck on a stale Feb 25 snapshot, showing only Built-in
+ Optional + Anthropic + LobeHub. The unified index already has 2078 skills
from skills.sh / ClawHub / LobeHub / GitHub taps / Claude Marketplace, and
BrowseShSource adds another ~330 — none of it was reaching the page.

Changes:

- website/scripts/extract-skills.py: read website/static/api/skills-index.json
  (the unified multi-source catalog, rebuilt twice daily) as the canonical
  external source. Keep the legacy skills/index-cache/ fallback for offline
  builds. Add friendly per-source labels (skills.sh, ClawHub, browse.sh,
  OpenAI, HuggingFace, Anthropic, LobeHub, etc.) and per-entry installCmd.
- website/src/pages/skills/index.tsx: add source pills + ordering for the 11
  new sources; render installCmd from the index entry.
- website/scripts/prebuild.mjs: when no local skills-index.json exists, fetch
  the live one from hermes-agent.nousresearch.com so local 'npm run build'
  matches production without burning GitHub API quota.
- scripts/build_skills_index.py: crawl BrowseShSource so browse.sh entries
  land in the unified index. Adjust source_order.
- tools/skills_hub.py: GitHubSource.DEFAULT_TAPS — openai/skills moved its
  skills into skills/.curated/ and skills/.system/, so add both as explicit
  taps (the listing code skips dotted dirs by design). Drop
  VoltAgent/awesome-agent-skills (README-only, no SKILL.md files) and
  MiniMax-AI/cli (singular skill, not a tap directory). Net effect: github
  source jumps from 83 → 143 skills, with OpenAI properly included.
- .github/workflows/deploy-site.yml: build the unified index BEFORE running
  extract-skills.py — previous order meant extract-skills always fell back
  to the legacy cache. Drop the 'skip if file exists' guard; the file is
  gitignored and must be rebuilt every deploy.
- .github/workflows/skills-index.yml: drop the broken 'deploy-with-index'
  job (it cp'd 'landingpage/\*' which no longer exists, failing every cron
  run since the landingpage move). Replace it with a workflow_dispatch
  trigger of deploy-site.yml so the index refresh still reaches production
  on schedule.
- website/docs/user-guide/features/skills.md: drop VoltAgent from the
  default-taps doc list to match the code.

Before: 695 skills (Built-in 90, Optional 84, Anthropic 16, LobeHub 505).
After:  2168 skills across 9 source pills, including the 1212 skills.sh
        entries the user expected to see.

Teknium eed891f1bb security: supply chain hardening — CI pinning, dep pinning, and code fixes (#9801)
CI/CD Hardening:
- Pin all 12 GitHub Actions to full commit SHAs (was mutable @vN tags)
- Add explicit permissions: {contents: read} to 4 workflows
- Pin CI pip installs to exact versions (pyyaml==6.0.2, httpx==0.28.1)
- Extend supply-chain-audit.yml to scan workflow, Dockerfile, dependency
  manifest, and Actions version changes

Dependency Pinning:
- Pin git-based Python deps to commit SHAs (atroposlib, tinker, yc-bench)
- Pin WhatsApp Baileys from mutable branch to commit SHA

Tool Registry:
- Reject tool name shadowing from different tool families (plugins/MCP
  cannot overwrite built-in tools). MCP-to-MCP overwrites still allowed.

MCP Security:
- Add tool description content scanning for prompt injection patterns
- Log detailed change diff on dynamic tool refresh at WARNING level

Skill Manager:
- Fix dangerous verdict bug: agent-created skills with dangerous
  findings were silently allowed (ask->None->allow). Now blocked.

Teknium 76019320fb feat(skills): centralized skills index — eliminate GitHub API calls for search/install
Add a CI-built skills index served from the docs site. The index is
crawled daily by GitHub Actions, resolves all GitHub paths upfront, and
is cached locally by the client. When the index is available:

- Search uses the cached index (0 GitHub API calls, was 23+)
- Install uses resolved paths from index (6 API calls for file
  downloads only, was 31-45 for discovery + downloads)

Total: 68 → 6 GitHub API calls for a typical search + install flow.
Unauthenticated users (60 req/hr) can now search and install without
hitting rate limits.

Components:
- scripts/build_skills_index.py: Crawl all sources (skills.sh, GitHub
  taps, official, clawhub, lobehub), batch-resolve GitHub paths via
  tree API, output JSON index
- tools/skills_hub.py: HermesIndexSource class — search/fetch/inspect
  backed by the index, with lazy GitHubSource for file downloads
- parallel_search_sources() skips external API sources when index is
  available (0 GitHub calls for search)
- .github/workflows/skills-index.yml: twice-daily CI build + deploy
- .github/workflows/deploy-site.yml: also builds index during docs deploy

Graceful degradation: when the index is unavailable (first run, network
down, stale), all methods return empty/None and downstream sources
handle the request via direct API as before.
