## What it does

The skill establishes a closed loop for code review fixes. It inspects your environment to detect GitHub, GitLab, or Perforce, then commits latest changes or shelves pending files. If Greptile is not currently analyzing the branch, the skill triggers it via `@greptile review` and polls check runs or pipeline jobs.

Once feedback arrives, the agent reads unresolved comments, edits the codebase, and pushes another commit. The cycle continues until Greptile returns a 5/5 confidence score with zero remaining issues. A hard ceiling of 5 iterations prevents runaway executions.

Running this requires authenticated `gh`, `glab`, or `p4` CLI binaries. Greptile must already be enabled on the target repository. If a review run takes longer than 10 minutes, the polling step times out and halts the task.

## Requirements
- Works with: GitHub, GitLab

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install greptileai/skills greploop
```

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

### Gemini CLI

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

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

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add greptileai/skills --skill greploop -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/greploop/SKILL.md

## When to use it
- resolve Greptile review comments on pull requests automatically
- reach a 5/5 Greptile confidence score without manual intervention
- re-shelve updated Perforce changelists during iterative reviews
- eliminate manual review trigger comments after code fixes

## Example prompts
- Run greploop on the current PR until confidence reaches 5/5
- Address Greptile comments on MR 42 and push fixes
- Execute greploop on pending Perforce files using --vcs perforce

# Greploop

Iteratively fix a PR/MR/CL until Greptile gives a perfect review: 5/5 confidence, zero unresolved comments.

## 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 for Perforce, then fall back to git remote detection:

```bash
# Check for Perforce environment
if p4 info >/dev/null 2>&1; then
  VCS="perforce"
else
  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, pass `--vcs perforce`.

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

**GitHub:**
```bash
gh pr view --json number,headRefName -q '{number: .number, branch: .headRefName}'
```

**GitLab:**
```bash
glab mr view --output json | jq '{iid: .iid, branch: .source_branch}'
```

Switch to the PR/MR branch if not already on it.

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

# Describe a specific CL
p4 describe -s <CL_NUMBER>
```

Ensure the correct workspace (`p4 client`) is set before proceeding.

Key field differences:
- GitHub: `number`, `headRefName`, `headRefOid`
- GitLab: `iid`, `source_branch`, `sha`
- Perforce: changelist number, `P4CLIENT`, shelved files

### 2. Loop

Repeat the following cycle. **Max 5 iterations** to avoid runaway loops.

#### A. Trigger Greptile review

Push/shelve the latest changes (if any):

**GitHub/GitLab:**
```bash
git push
```

**Perforce:**
```bash
# Re-shelve to update the shelved files for review
p4 shelve -f -c <CL_NUMBER>
```

Wait for checks to start after push/shelve:

```bash
sleep 5
```

**GitHub** — check if Greptile is already running before posting a new trigger comment:

```bash
GREPTILE_STATE=$(gh pr checks <PR_NUMBER> --json name,state | jq -r '.[] | select(.name | test("greptile"; "i")) | .state')
```

If Greptile is **not** already running (`PENDING` or `IN_PROGRESS`), request a fresh review:

```bash
if [ "$GREPTILE_STATE" != "PENDING" ] && [ "$GREPTILE_STATE" != "IN_PROGRESS" ]; then
  gh pr comment <PR_NUMBER> --body "@greptile review"
fi
```
