Debugs a red CI job to root cause instead of blind-rerunning — reproduce locally in the SAME image (act -j , gitlab-runner exec, circleci local execute, or docker run the exact pinned digest), read the full log + the real exit code (124=timeout, 137=OOM/SIGKILL, 143=SIGTERM, 139=segfault), then classify into flaky / env-drift / poisoned-or-stale cache / resource-OOM / missing-secret / timeout / test-ordering / network, and confirm with a targeted experiment — diff local-vs-CTRL env (printenv | sort, tool --version, lockfile hash), run clean (no cache, --no-cache/clear key) vs cached, isolate ONE matrix leg, bisect with git bisect run, re-run with debug logging (ACTIONSSTEPDEBUG=true, CIDEBUGTRACE=true, set -x) or open an interactive runner (tmate/debug with SSH/--privileged shell) — and fix the cause (pin the digest, scope the cache key, raise the limit, randomize then fix test order) not the symptom.

Quick start
Copy the install prompt. Use the green button above this README.
Send it to your agent. Paste it into your coding agent’s chat and send.
Review the setup. Your agent checks the skill’s instructions, requirements, and installation scope.
Debugs a red CI job to root cause instead of blind-rerunning — reproduce locally in the SAME image (`act -j <job>`, `gitlab-runner exec`, `circleci local execute`, or `docker run` the exact pinned digest), read the full log + the real exit code (124=timeout, 137=OOM/SIGKILL, 143=SIGTERM, 139=segfault), then classify into flaky / env-drift / poisoned-or-stale cache / resource-OOM / missing-secret / timeout / test-ordering / network, and confirm with a targeted experiment — diff local-vs-CTRL env (`printenv | sort`, tool `--version`, lockfile hash), run clean (no cache, `--no-cache`/clear key) vs cached, isolate ONE matrix leg, bisect with `git bisect run`, re-run with debug logging (`ACTIONS_STEP_DEBUG=true`, `CI_DEBUG_TRACE=true`, `set -x`) or open an interactive runner (`tmate`/`debug with SSH`/`--privileged` shell) — and fix the cause (pin the digest, scope the cache key, raise the limit, randomize then fix test order) not the symptom.
