Splits failed GitHub Actions jobs across parallel subagents, each fixing its own slice. Useful when CI breaks in several places at once.

## What it does

The skill triages a failed GitHub Actions run job by job. You start with `gh run list --limit 5`, then pull the failed step logs with `gh run view <RUN_ID> --log-failed`. Every failed job goes to its own `generalPurpose` subagent, all launched in a single message so they run at the same time.

Each subagent gets the job name, the run URL, the branch and the relevant log excerpt. It infers the root cause from the stack trace, edits only what that job needs, and reruns the failing command locally. The report covers what broke, what changed and whether the local check passes. Two failures with the same root cause in the same file go to one agent, because parallel edits to shared files collide.

You need the GitHub CLI installed and authenticated with `gh auth login`, plus push access so fixes can be pushed and CI rerun. Without `gh`, download the logs from the web UI and paste them into the chat. Redact secrets before pasting. A single job with one clear error is faster to fix in the main agent, and flaky infrastructure is a retry, not a triage.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add spencerpauly/awesome-cursor-skills --skill parallel-ci-triage -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/parallel-ci-triage/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/parallel-ci-triage/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add spencerpauly/awesome-cursor-skills --skill parallel-ci-triage -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/parallel-ci-triage/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add spencerpauly/awesome-cursor-skills --skill parallel-ci-triage -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/parallel-ci-triage/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install spencerpauly/awesome-cursor-skills parallel-ci-triage
```

2. **Manually: put the files in place**
- File: `.github/skills/parallel-ci-triage/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add spencerpauly/awesome-cursor-skills --skill parallel-ci-triage -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/spencerpauly/awesome-cursor-skills --path resources/parallel-ci-triage
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/parallel-ci-triage/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add spencerpauly/awesome-cursor-skills --skill parallel-ci-triage -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/spencerpauly/awesome-cursor-skills/tree/HEAD/resources/parallel-ci-triage/SKILL.md

## When to use it
- triage a failed GitHub Actions run by job
- fix several independent CI failures in one pass
- pull failed step logs with gh
- verify a fix with the same command that failed in CI
- push changes and watch the new run

## Example prompts
- CI failed in three jobs — pull the logs and launch a subagent per job
- Take the latest failed run and fix the lint and e2e jobs in parallel
- Check the fixes pass locally, commit, then run gh run watch

# Parallel CI Triage

Speed up fixing broken CI by splitting failing **jobs** (or independent failure clusters) across parallel subagents. Each subagent owns one vertical slice: logs, root cause, code fix, and local verification for that slice.

## Prerequisites

- **GitHub CLI** (`gh`) installed and authenticated (`gh auth login`), or use the GitHub web UI / API to copy logs manually.
- Push access to the repo so fixes can be pushed and CI re-run.

## Workflow

### 1. Identify the failing run

From the repo root:

```bash
gh run list --limit 5
gh run view <RUN_ID> --log-failed
```

Or open the Actions tab, open the failed workflow run, and note which **jobs** failed (not just which step — group by job name).

If `gh` is unavailable, download logs from the GitHub UI and paste them into the conversation.

### 2. Split by job (or by failure cluster)

- **One subagent per failed job** when jobs test different things (e.g. `lint`, `test-node-18`, `e2e`).
- **One subagent per independent failure cluster** when a single job logs multiple unrelated errors — but prefer one job per agent to avoid conflicting edits in the same files.

If two failures share the same root cause in the same file, assign **one** subagent to fix both.

### 3. Launch parallel subagents

For each failing job, launch a `generalPurpose` subagent in a **single message** so they run concurrently:

```
Task: Fix CI failure for job "<JOB_NAME>"

Context:
- Workflow run: <RUN_URL or RUN_ID>
- Branch: <branch>
- Relevant log excerpt (failed steps only):
<paste gh run view --job <JOB_ID> --log or the failed section>

Instructions:
1. Infer the root cause from the log (command, stack trace, file:line).
2. Open and edit only what this job requires.
3. Run the same commands locally that failed in CI (or the narrowest equivalent, e.g. `npm run lint`, `pytest tests/foo`, `pnpm test --filter pkg`).
4. Report: what failed, what you changed, and confirmation that the local command passes.
```

Include the **exact** failing command and error lines so the subagent does not guess.

### 4. Merge and verify

- Collect each subagent’s changed files. Resolve overlaps manually if two agents touched the same file.
- Run the full CI-equivalent locally when possible:

  ```bash
````
