CI Prep
Prepare the current state for CI. If CI is already failing, fetch and analyze the logs first.
Arguments
--failing — Indicates a GitHub Actions run is already failing. When present, you MUST execute Step 1 before doing anything else.- Any other argument is treated as a job name to focus on (but all failures are still reported).
If --failing is NOT passed, skip directly to Step 2.
Step 1 — Fetch failed CI logs (only when --failing)
You MUST do this before any other work.
BRANCH=$(git branch --show-current)
PR_JSON=$(gh pr list --head "$BRANCH" --state open --json number,title,url --limit 1)
If the JSON array is empty, stop immediately:
No open PR found for branch $BRANCH. Create a PR first.
Otherwise fetch the logs:
PR_NUMBER=$(echo "$PR_JSON" | jq -r '.[0].number')
gh pr checks "$PR_NUMBER"
RUN_ID=$(gh run list --branch "$BRANCH" --limit 1 --json databaseId --jq '.[0].databaseId')
gh run view "$RUN_ID"
gh run view "$RUN_ID" --log-failed
Read every line of --log-failed output. For each failure note the exact file, line, and error message. If a job name argument was provided, prioritize that job but still report all failures.
Step 2 — Analyze the CI workflow
- Find the CI workflow file. Look in
.github/workflows/ for ci.yml, build.yml, test.yml, checks.yml, main.yml, pull_request.yml, or any workflow triggered on pull_request or push.
- Read the workflow file completely. Parse every job and every step.
- Extract the ordered list of commands the CI actually runs. In a spec-compliant repo this is
make lint → make test → make build (REPO-STANDARDS-SPEC [MAKE-TARGETS]), but the actual CI may use npm, cargo, dotnet, raw shell commands, or anything else. Extract what is actually there.
- Note any environment variables, matrix strategies, or conditional steps that affect execution.
Do NOT assume the steps are make lint, make test, make build. The actual CI may run different commands, in a different order. Extract what the CI actually does. If you find extra targets beyond the 7 in [MAKE-TARGETS] (e.g. make fmt-check, make coverage-check), flag them in your final report — they should be consolidated by the agent-pmo skill.
Step 3 — Run each CI step locally, in order
Work through failures in this priority order:
- Formatting — run auto-formatters first to clear noise
- Compilation errors — must compile before lint/test
- Lint violations — fix the code pattern
- Runtime / test failures — fix source code to satisfy the test
For each command extracted from the CI workflow:
- Run the command exactly as CI would run it (adjusting only for local environment differences like not needing
actions/checkout).
- If the step fails, stop and fix the issues before continuing to the next step.
- After fixing, re-run the same step to confirm it passes.
- Move to the next step only after the current one succeeds.
Hard constraints
- NEVER modify test files — fix the source code, not the tests
- NEVER add suppressions (
#[allow(...)], // eslint-disable, #pragma warning disable)
- NEVER use
any in TypeScript to silence type errors
- NEVER delete or ignore failing tests
- NEVER remove assertions
If stuck on the same failure after 5 attempts, ask the user for help.
Step 4 — Report
- List every step that was run and its result (pass/fail/fixed).
- If any step could not be fixed, report what failed and why.
- Confirm whether the branch is ready to push.
Step 5 — Commit/Push (only when --failing)
Once all CI steps pass locally:
- Commit, but DO NOT MARK THE COMMIT WITH YOU AS AN AUTHOR!!! Only the user authors the commit!
- Push
- Monitor until completion or failure
- Upon failure, go back to Step 1
Rules
- Always read the CI workflow first. Never assume what commands CI runs.
- Do not push if any step fails (unless
--failing and all steps now pass)
- Fix issues found in each step before moving to the next
- Never skip steps or suppress errors
- If the CI workflow has multiple jobs, run all of them (respecting dependency order)
- Skip steps that are CI-infrastructure-only (checkout, setup-node/python/rust actions, cache steps, artifact uploads) — focus on the actual build/test/lint commands
Success criteria
- Every command that CI runs has been executed locally and passed
- All fixes are applied to the working tree
- The CI passes successfully (if you are correcting and existing failure)
