## What it does

The skill splits bug triage into two distinct layers. Deterministic fingerprinting handles noise reduction and deduplication, tasks where language models often fail. The LLM steps in afterward to assess severity, suggest root causes, and write the ticket. If `.agents/qa-project-context.md` exists in the repository, the skill reads the tech stack and component mappings directly from it.

Processing runs through seven stages. First, a normalizer strips timestamps, UUIDs, ephemeral ports, temp paths, and ANSI codes from raw logs. Next, it extracts stable anchors: test names, exception types, HTTP status codes, and top stack frames without line numbers. From these anchors, it computes a canonical hash. Auto-closing duplicates without human confirmation is explicitly blocked, because false deduplication wastes more engineering time than manual triage.

If auto-classification accuracy drops below 85%, the pipeline requires retuning. Note that this skill does not handle runtime self-healing for flaky locators, nor does it generate new tests from production telemetry.

## Requirements
- Works with: Playwright

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add petrkindlmann/qa-skills --skill ai-bug-triage -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add petrkindlmann/qa-skills --skill ai-bug-triage -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add petrkindlmann/qa-skills --skill ai-bug-triage -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install petrkindlmann/qa-skills ai-bug-triage
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add petrkindlmann/qa-skills --skill ai-bug-triage -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/petrkindlmann/qa-skills --path skills/ai-bug-triage
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add petrkindlmann/qa-skills --skill ai-bug-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/petrkindlmann/qa-skills/tree/HEAD/skills/ai-bug-triage/SKILL.md

## When to use it
- Strip timestamps, ANSI codes, and ports from CI logs for reliable comparison
- Build deterministic failure fingerprints from exception types and stack frames
- Cluster near-duplicate test failures without relying solely on an LLM
- Draft bug tickets with reproduction steps and root cause hypotheses

## Example prompts
- Analyze these failed CI logs and generate failure fingerprints
- Review the Playwright failure output and draft a ticket for Jira

description: >-
  Hybrid fingerprint + LLM pipeline for bug classification, deduplication, and ticket
  generation. Normalizes CI logs, creates stable fingerprints, clusters near-duplicates,
  then uses LLM for severity classification and ticket writing. Includes bug reporting
  templates and severity/priority matrix. Use when: "bug triage," "classify bugs,"
  "failure analysis," "auto-classify," "CI failures," "bug report," "defect template."
  Not for: runtime self-healing of one flaky locator — use test-reliability. Not for:
  designing new tests from production telemetry — use observability-driven-testing.

<objective>
A hybrid pipeline for bug classification, deduplication, and ticket generation. Deterministic fingerprinting handles deduplication (what LLMs are bad at); LLM handles explanation, severity assessment, and ticket writing (what LLMs are good at).

**Key reframe:** The LLM is best at explaining and routing, not deduplication. Teach agents to DESIGN the pipeline, not BE the pipeline.
</objective>

## Discovery Questions

Check `.agents/qa-project-context.md` first — it carries tech stack, component mapping, and known flaky areas that improve classification accuracy. Use it and skip anything already answered there. Then clarify:

1. **What is the failure source?**
   - CI pipeline logs (GitHub Actions, GitLab CI, Jenkins, CircleCI)
   - Test framework output (Playwright, Jest, pytest, Vitest)
   - Production error monitoring (Sentry, Datadog, Bugsnag)
   - Manual bug reports from QA or users

2. **What is the ticket destination?**
   - Jira, Linear, GitHub Issues, Azure DevOps, Shortcut
   - What fields are required? (component, severity, priority, labels)
   - What workflows exist? (triage board, auto-assignment rules)

3. **What is the deduplication scope?**
   - Same test run? Same sprint? Same release? All time?
   - Do you already have fingerprinting? What is the current duplicate rate?

4. **What approval workflow is needed?**
   - Auto-create tickets with human review?
   - Suggest tickets for human approval before creation?
   - Auto-close duplicates? (dangerous -- require approval)

5. **What historical data exists?**
   - Past bug reports with resolution data?
   - Flaky test history? Known environment issues?
   - Component ownership mapping?
