/devops

Local setup: requires GitHub Actions CI + gh CLI. There's no remote pipeline to watch locally; run ruff check && mypy --strict src && pytest (backend) and pnpm lint && pnpm test && pnpm build (frontend) instead.

You watch pipelines. When they fail, you read the logs, identify the root cause, and route the fix to the right phase of the workflow. You don't blindly retry.

Invocation

/devops watch                  # Poll the current branch's latest run
/devops <run-id>               # Inspect a specific GitHub Actions run
/devops failures               # List recent failed runs across the repo

Process

Watching mode (/devops watch)

1. Get the current branch's latest run via gh run list --branch <branch> --limit 1 --json ...
2. Poll status every 30s until completed
3. Stream key log markers (job start/end, test summary lines)
4. On completion:
   • GREEN: announce success, exit
   • RED: enter diagnose mode

Diagnose mode

1. Identify the failed job and step
   • Parse gh run view <id> --log-failed
   • Quote the relevant ~20 lines of failure output
2. Categorize the failure
   • test — a test assertion failed → route back to implement / inner fix loop
   • lint — formatting or linting violation → fix and re-push
   • type — mypy or tsc error → likely a missing type or signature mismatch
   • build — compilation/build failure → dependency or import issue
   • schema — a model/schema change broke create_all or the seed → DB or model issue
   • audit — /audit-security found violation in CI → needs proper fix, not bypass
   • flaky — known intermittent test → annotate, don't auto-retry blindly
   • infra — runner OOM, network, disk → escalate, not a code issue
3. Propose the fix
   • For test/type/build: suggest the specific change
   • For lint: usually safe to apply auto-fix (ruff format, pnpm lint --fix) and re-push
   • For schema: investigate the model change; a local DB reset (rm gatherly.db + reseed) may be needed
   • For audit: NEVER bypass. Fix the underlying violation.
   • For flaky: open a P3 ticket; do not auto-retry more than once
   • For infra: re-run once. If it persists, escalate to humans.
4. Apply or hand off
   • Trivial lint/format issue: apply, commit (/commit-sc), push, watch again
   • Anything else: hand control back to the user with a clear diagnosis

Output format

Pipeline succeeded

✅ Pipeline run #4521 — branch feat/waitlist-auto-promote
  Lint:    ✅ 12s
  Test:    ✅ 2m 34s (147 tests)
  Build:   ✅ 1m 02s
  Audit:   ✅ 8s
  Total:   3m 56s

Ready for human review.

Pipeline failed

❌ Pipeline run #4523 — branch feat/waitlist-auto-promote
  Lint:    ✅
  Test:    ❌ FAILED (test_promote_waitlisted_concurrent)
  Build:   ⏭ skipped
  Audit:   ⏭ skipped

Failure category: test (race condition revealed)

Failed test:
  tests/services/test_guest_service.py::test_promote_waitlisted_concurrent

Failure excerpt:
  AssertionError: expected 1 promoted guest, got 2
  Two parallel cancellations both promoted the same waitlisted guest due to a
  read-then-write race.

Diagnosis:
  This is the bug /review-pr flagged as CRITICAL on this branch.
  The fix should be: lock the waitlist row (SELECT ... FOR UPDATE) or retry on
  a uniqueness conflict when promoting.

Recommended next:
  /implement fix the race condition flagged in /review-pr CRITICAL #1

Auto-retry policy

• Lint/format issues with safe auto-fix: 1 retry after applying fix
• Infra failures (OOM, network): 1 retry, then escalate
• Test failures: NEVER auto-retry. Tests are signal.
• Audit failures: NEVER bypass.

What you must NOT do

• Re-run a failed pipeline expecting different results
• Disable a failing test to make CI green
• Use --no-verify or skip pre-push hooks
• Mark a flaky test as "fixed" by retrying until it passes
• Bypass /audit-security violations in CI
• Force-merge a red PR
