## What it does

This skill guides agents through fixing verified bugs. It relies on the `investigate` skill first, requiring an exact trace ID, log entry, or error group before touching code. Before creating a branch, it searches GitHub using `gh pr list` to make sure no duplicate pull request exists. If the issue is a feature flag flip or external configuration change, it describes the fix instead of touching code.

Diffs stay minimal. The workflow explicitly forbids refactoring surrounding modules, bumping package versions to mask symptoms, or modifying tests to hide failures. It checks local rules in `CLAUDE.md` or `agents.md`, sets git identity according to `pr-conventions.md`, and commits only targeted changes.

Without an authenticated GitHub CLI session via `gh auth status`, the skill stops immediately. It will not attempt fallback authentication methods.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add launchdarkly/ai-tooling --skill create-fix-pr -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add launchdarkly/ai-tooling --skill create-fix-pr -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add launchdarkly/ai-tooling --skill create-fix-pr -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install launchdarkly/ai-tooling create-fix-pr
```

2. **Manually: put the files in place**
- File: `.github/skills/create-fix-pr/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add launchdarkly/ai-tooling --skill create-fix-pr -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/launchdarkly/ai-tooling --path skills/observability/create-fix-pr
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add launchdarkly/ai-tooling --skill create-fix-pr -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/launchdarkly/ai-tooling/tree/HEAD/skills/observability/create-fix-pr/SKILL.md

## When to use it
- Track down root causes using trace IDs and error logs
- Check GitHub for duplicate pull requests before filing
- Create minimal pull requests adhering to repository rules
- Recommend config or flag changes when code edits are unnecessary

## Example prompts
- Investigate the trace ID `trace-991` and open a minimal PR fixing the root cause.
- Check if an open PR exists for the checkout timeout, then prepare a targeted patch.
- Find the bug causing error group `AUTH_FAIL_01` and submit a PR following CLAUDE.md rules.

# Create a fix PR

## Overview

You are investigating a problem and filing a pull request that resolves it. This builds on the `investigate` skill — do the investigation properly first, don't jump to a fix without evidence.

Use the `gh` CLI for all GitHub operations (auth comes from your `gh` login) and standard `Bash` / `Edit` / `Read` / `Grep` for everything else.

## Workflow

1. **Investigate.** Use the `investigate` skill to find the root cause. Cite the exact trace ID, log line, error group, and code location that pins the problem.
2. **Confirm there isn't already a PR open.** Before filing anything, search GitHub for an existing open PR addressing the same issue — `gh pr list --search "<keywords>" --state open`. If one exists, direct the user to it — do not create a duplicate.
3. **Judge whether a PR is the right tool.** If the fix requires a config change, a flag flip, or a change outside the code you can access, describe the solution instead of filing a PR.
4. **Get the repo.** Clone it if you don't already have it locally — `gh repo clone <owner>/<repo>`.
5. **Check for repo conventions.** Read `agents.md` or `CLAUDE.md` at the repo root — these describe repo-specific rules your fix needs to respect.
6. **Make the change.** Minimal diff. Don't refactor surrounding code, don't add features, don't fix unrelated bugs you happen to notice. One PR, one fix.
7. **Set git identity** before committing — see `pr-conventions.md`.
8. **Commit, push, and file the PR.** See `pr-conventions.md` for branch naming and PR body rules.

## What's a good fix

- Changes the smallest possible number of lines
- Preserves current production behavior unless the bug IS the current behavior
- Doesn't depend on assumptions you can't verify from the evidence
- Would pass a `code-review` skill's check if one existed

## What isn't

- Sweeping refactors unrelated to the reported problem
- Speculative null checks or error handling added "while you're in there"
- Changes to tests that hide the underlying bug
- Bumping dependency versions to fix a symptom

## Restricted tools

If `gh` isn't installed or `gh auth status` shows no auth, surface the error to the user and stop — don't try alternative auth schemes.

## Never include in a PR

- GitHub access tokens or any other secrets or credentials.
- Debugging logs or print statements you added during investigation.

Follow the repo's own commit and PR conventions for everything else.
