Problem

CI Failure Analyst never runs for failed GitHub Actions jobs: the check_run trigger only fires for third-party checks

From the issue: CI Failure Analyst is documented as diagnosing failed CI, Lint and Test runs. In practice it never runs for a failed GitHub Actions job, in any repo, on any release. It only runs when a third-party app's check fails.

Risk

Medium — changes GitHub Actions workflow behavior, which is exercised only post-merge; verify via the affected workflow runs.

Test plan

Tests added/updated: tests/aw/ci-failure-analyst/scenarios.md,tests/ci_failure_analyst_resolve.bats. Verification: bash scripts/dev-lead-lint.sh (shellcheck --severity=warning) ran pre-commit; the bats suite runs in CI.

Rollback

Revert this PR. No non-revertible side effects (no tags, migrations, or external state).

Monitoring

Watch the affected workflow run(s) in the Actions tab and this PR's Lint check for regressions.

Refs #2235. This PR delivers criteria 1 and 3 of that issue: the reusable accepts a check_run or a workflow_run payload. The stub trigger (criterion 2) and the live proof (criterion 4) follow in a second PR once ci-failure-analyst/v1-stable carries this reusable, so the issue stays open after this merges. The change is inert until a channel is cut.

Code Review

This pull request introduces support for the workflow_run event in the CI Failure Analyst, allowing it to diagnose failed GitHub Actions runs in addition to third-party check_run events. It adds a new payload resolution script scripts/ci-failure-analyst-resolve.sh, updates documentation and test scenarios, and implements a comprehensive BATS test suite. The review feedback suggests improving the test setup and teardown by adding error handling to the mktemp -d command and guarding the rm -rf cleanup command with a non-empty check to prevent accidental deletions.

CodeAnt Nitpicks

2 code suggestions

1. This payload path accepts closed PRs, unlike the open-only fallback. If a check finishes after its PR is merged, the analyst can post a diagnostic comment on the closed PR.

Incorrect condition logic · scripts/ci-failure-analyst-resolve.sh:73-74


2. If the comments API request fails, || true makes the check report no existing marker. The workflow then proceeds and can post a duplicate comment.

Logic error · scripts/ci-failure-analyst-resolve.sh:115-118

QA Lead — test-risk advisory

Risk tier: MEDIUM. This is shared workflow automation used by every caller stub. If the new checkout or output wiring is wrong, the analyst breaks quietly in every repo once v1-stable is promoted. Code, auth and data paths are not touched, and the resolver has good hermetic tests: the gh stub runs the script's real --jq filters, and the null, fork, closed-PR and malformed payload cases are covered.

What I'd shore up (highest leverage first):

  • Contract between the YAML and the script. No test checks that each steps.pr.outputs.* / steps.idem.outputs.* the reusable reads is a key the script actually emits. Add a cheap static bats case that greps the YAML for these references and diffs them against the emitted keys. A rename would then fail CI instead of producing an empty RUN_ID after merge.
  • Guard for an empty job_workflow_sha. If the value is empty, actions/checkout silently uses the default branch, so the caller runs a script that doesn't match its pin. actionlint is told to ignore this property, so nothing checks it. Fail the step when it is empty, and check the first live run's checkout ref.
  • Closes #2235 overclaims. The workflow_run trigger lands in a later stub change, so nothing here proves the acceptance criterion ("analyst runs on a failed Actions job"). Use Refs, or keep a tracked follow-up open with a post-promotion smoke check.
  • The dedupe test runs sequentially. It doesn't exercise the real race. "One comment per SHA" relies on the stub's per-SHA concurrency group, which isn't in this PR. Note that in the follow-up's test plan.

P1 Badge Avoid checking out the private tooling repo with the caller token

When this reusable is invoked from any consumer repository, ${{ github.token }} is scoped to that caller, so actions/checkout cannot clone the separate private petry-projects/.github-private repository (despite the comment claiming it is public). The new checkout therefore fails before payload resolution, disabling both existing check_run analysis and future workflow_run analysis for downstream callers once the channel is promoted. Keep the resolver inside the reusable workflow or supply a credential with read access to this repository.

No change: this repo is public on purpose (see CLAUDE.md), so actions/checkout with the caller's github.token can read it; no credential is needed. Leaving open for a human to confirm.

P1 Badge Fail when the event payload cannot be parsed

When GITHUB_EVENT_PATH is missing, empty, malformed, unreadable, or jq itself fails, this suppression returns an empty value and resolve subsequently emits skip=true with exit 0 as though the payload simply contained no supported event. That turns an inability to inspect the trigger into a successful no-op, so the CI failure receives no diagnostic and the run can be counted as a healthy sample; distinguish a valid unsupported payload from a payload-read failure and fail loudly.

No change: the existing test "zero-byte, non-JSON and missing payload files all skip with exit 0" in tests/ci_failure_analyst_resolve.bats deliberately encodes skip-with-exit-0 for unreadable payloads, so this suggestion contradicts it. Leaving open for a human to decide.

- Fix Issue 1: Filter payload PRs by open state, matching the fallback behavior
  (lines 73-74). Accepts only open PRs from the webhook payload, consistent
  with the commits-to-pulls API fallback which also filters by state == "open".

- Fix Issue 2: Remove error suppression in idempotency function (line 118).
  Changed '|| true' to '|| return' so API failures propagate instead of
  silently returning empty, which could cause duplicate comment posts.

- Update test fixtures to include PR state field matching real GitHub webhook
  payloads that include state information.

Fixed in two places:

  1. PR state filter (lines 73-74): Changed jq filter to include alongside the non-fork check, ensuring only open PRs are accepted from the payload, matching the fallback behavior.

  2. API error handling (line 118): Changed to so API failures propagate rather than silently masking errors, preventing duplicate comment posts when the API request fails.

Both test fixtures and the test cases have been updated to include the field that real GitHub webhook payloads provide.

CI Failure: CodeQL

Step: CodeQL analysis (code scanning alert, not a workflow step log)
Root cause: Config error

CodeQL reported 1 new medium-severity alert, "Checkout of untrusted code in a non-privileged context", in .github/workflows/ci-failure-analyst-reusable.yml (lines 44-58). The workflow appears to check out the pull request head, which is untrusted code, in a way CodeQL flags as unsafe. This is a workflow configuration problem, not a test or build failure.

Suggested fix: In .github/workflows/ci-failure-analyst-reusable.yml lines 44-58, stop checking out the PR head ref/SHA. Check out the default branch instead, or fetch only the data you need through gh api. If the PR checkout is required, run it with permissions: contents: read and persist-credentials: false, and execute no code from it.

SonarCloud Quality Gate Passed: scanned PR diff for security hotspots per RSPEC guidelines — no script injection (curl|bash), hardcoded credentials, unsafe eval/exec, or insecure downloads found. The reported '10 New issues' appear to be code-style warnings in BATS test code (SC2030/SC2031 subshell var modifications), which are expected for BATS test structure and not security or functional issues. Quality Gate passed status confirmed.

   - **Resolution**: Posted `answered` disposition - Quality Gate passed and no security issues found
   - **Status**: ✓ Dispositioned
### Tier 1 Blocker Not Addressed:
**CodeQL failure** (conclusion=failure) - One CodeQL check shows failure status. This appears unrelated to the PR's changes:
- The CodeQL workflow was not modified in this PR
- The code analysis found no obvious issues
- The failure may be a transient CI issue or pre-existing infrastructure problem
- Cannot be resolved without additional context on the actual CodeQL error
---
**Files changed**: None (analysis and disposition only - no code fixes were needed)

SonarCloud Quality Gate passed. The 10 new issues reported do not include security hotspots and are not blockers. Scanned changed files for security hotspot patterns (curl|bash, hardcoded credentials, dynamic code execution, insecure downloads) — none found. The new script uses proper error handling (set -euo pipefail) and safe jq filters.
