wait-for-ci

name	wait-for-ci
description	Poll gh pr checks --watch until all required checks finish. Distinguishes required vs optional, handles flaky reruns, enforces timeout. Triggers: wait for ci, watch checks, ci status.

wait-for-ci

Block until CI verdict known. Emit JSON. No prose narration.

Inputs

Var	Source
PR	$ARGUMENTS or gh pr view --json number -q .number
TIMEOUT_MIN	default 30
REQUIRED	from branch-protection; cached in .github/required-checks.json

Loop

PR="${1:-$(gh pr view --json number -q .number)}"
DEADLINE=$(( $(date +%s) + 60 * ${TIMEOUT_MIN:-30} ))

# Watch mode — blocks until first verdict
gh pr checks "$PR" --watch --fail-fast=false || true

# Then snapshot
gh pr view "$PR" --json statusCheckRollup,number,headRefName \
  > /tmp/ci.json

Classify (jq)

jq '
  .statusCheckRollup
  | group_by(.conclusion // .status)
  | map({k: (.[0].conclusion // .[0].status), n: length, names: map(.name)})
' /tmp/ci.json

Bucket	Meaning	Action
SUCCESS	green	continue
FAILURE CANCELLED TIMED_OUT ACTION_REQUIRED	red	emit failed summary; route to pr-rebase-and-recover or domain-engineer
IN_PROGRESS QUEUED PENDING	running	re-poll until deadline
NEUTRAL SKIPPED	optional, ignore unless required	check REQUIRED

Re-poll loop (when only PENDING left)

while [ $(date +%s) -lt $DEADLINE ]; do
  gh pr view "$PR" --json statusCheckRollup -q \
    '[.statusCheckRollup[] | select(.status != "COMPLETED")] | length' \
    | grep -q '^0$' && break
  sleep 30
done

Flaky re-runs

• A check that failed once and passed on rerun → record but accept.
• A check that flaps ≥3 times in one PR → emit flaky event, do NOT block; flag in docs/guides/testing/ci.md (Agent 20).
• Re-run a single check:

gh run rerun "$RUN_ID" --failed

Required vs optional

• Required list lives at .github/required-checks.json (array of check names).
• A FAILURE in a non-required check → emit optional_failure, do NOT block merge.

Output (JSON)

{
  "pr": 123,
  "verdict": "green|red|timeout",
  "required_pass": 12,
  "required_fail": 0,
  "optional_fail": 1,
  "duration_s": 412,
  "flaky": ["bench-windows"],
  "failing_checks": []
}

Timeout policy

TIMEOUT_MIN	Tier	Action on timeout
15	unit/lint	emit timeout, route to ci-engineer
30	default	escalate to mastermind
60	bench/visual	acceptable; keep polling once if --patient

SLO target: required checks green in ≤15 min (see docs/guides/pr-workflow.md).
