## What it does

The skill detects your version control system through `.p4config`, environment variables, or git remote URLs. It then locates the active PR, MR, or pending changelist. If checks are still running, it polls their status every 30 seconds until all pipelines finish.

Next, it analyzes CI results and review comments, catching automated notes from bots like Greptile alongside teammate feedback. Issues are grouped into actionable fixes, informational notes, and resolved items. If you approve, the agent edits files, commits changes, or re-shelves Perforce files directly.

Execution fails immediately if `gh`, `glab`, or `p4` CLI tools lack active authentication on your local machine.

## Requirements
- Works with: GitHub, GitLab

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add greptileai/skills --skill check-pr -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add greptileai/skills --skill check-pr -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add greptileai/skills --skill check-pr -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install greptileai/skills check-pr
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add greptileai/skills --skill check-pr -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/greptileai/skills --path skills/check-pr
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add greptileai/skills --skill check-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/greptileai/skills/tree/HEAD/skills/check-pr/SKILL.md

## When to use it
- Track running CI checks until completion without refreshing browser tabs
- Triage unresolved reviewer and bot comments into actionable tasks
- Detect placeholder TODO items inside PR and MR descriptions
- Apply requested code modifications and push follow-up commits

## Example prompts
- Check my current pull request and summarize unresolved comments
- Wait for CI checks on MR 42 and fix any failures
- Inspect my pending Perforce changelist before submission

  Checks a GitHub, GitLab, or Perforce (p4) pull request (or merge request, or shelved changelist)

# Check PR

Analyze a pull request (GitHub), merge request (GitLab), or shelved changelist (Perforce) for review comments, status checks, and description completeness, then help address any issues found.

## Inputs

- **PR/MR/CL number** (optional): If not provided, detect the PR/MR for the current branch, or the default pending changelist for p4.

## Instructions

### 0. Detect platform

First check if the user is working in a Perforce depot by looking for a `.p4config` file or `P4CLIENT`/`P4PORT` environment variables:

```bash
# Check for Perforce environment
if p4 info >/dev/null 2>&1; then
  VCS="perforce"
else
  # Fall back to git remote detection
  REMOTE_URL=$(git remote get-url origin)
  if echo "$REMOTE_URL" | grep -qi "gitlab"; then
    VCS="gitlab"
  else
    VCS="github"
  fi
fi
```

For self-hosted GitLab instances whose hostname doesn't contain "gitlab", the user can override by passing `--vcs gitlab` as an input. For Perforce, the user can override by passing `--vcs perforce`.

### 1. Identify the PR/MR/CL

If a number was provided, use it. Otherwise, detect it:

**GitHub:**
```bash
gh pr view --json number -q .number
```

**GitLab:**
```bash
glab mr view --output json | jq '.iid'
```

**Perforce:**
```bash
# List pending changelists for the current user/client
p4 changes -s pending -u $P4USER -c $P4CLIENT
```

Key field differences between platforms:
- GitHub: `number`, `headRefName`, `headRefOid`
- GitLab: `iid`, `source_branch`, `sha`
- Perforce: changelist number (CL), `shelved` files for in-review CLs

### 2. Fetch PR/MR/CL details

**GitHub:**
```bash
gh pr view <PR_NUMBER> --json title,body,state,reviews,comments,headRefName,statusCheckRollup
gh api repos/{owner}/{repo}/pulls/<PR_NUMBER>/comments
gh api --paginate "repos/{owner}/{repo}/issues/<PR_NUMBER>/comments?per_page=100"
```

GitHub PRs are also issues, so general PR comments live on the issue comments endpoint. Greptile may edit a single general PR comment on each review cycle instead of creating a new review or comment. Always inspect the latest Greptile-authored general comment by `updated_at`, including any "Prompt to fix all with AI" section, before concluding that the PR is clear.

**GitLab:**
```bash
glab mr view <MR_IID> --output json
# Fetch discussions (inline diff comments are type "DiffNote"; general comments have null type)
glab api "projects/:fullpath/merge_requests/<MR_IID>/discussions"
```
