# GitLab Skill

## Overview

Use this skill to inspect and update GitLab merge requests, notes, pipelines,
and job logs against GitLab.com or self-managed GitLab instances.

This skill is the repository-local Python workflow for GitLab tasks. It is not
the official GitLab MCP server integration surface.

This first hve-core implementation is Python-only. Run the CLI through
`python scripts/gitlab.py` and prefer `--fields` for read operations to keep
output concise.

## Prerequisites

The skill requires Python 3.11 or later.

Set these environment variables before running any command:

| Variable         | Required | Example              | Purpose                                       |
|------------------|----------|----------------------|-----------------------------------------------|
| `GITLAB_URL`     | Yes      | `https://gitlab.com` | GitLab instance URL                           |
| `GITLAB_TOKEN`   | Yes      | `glpat-...`          | Personal access token sent as `PRIVATE-TOKEN` |
| `GITLAB_PROJECT` | No       | `group/project`      | Project path or numeric project ID            |

If `GITLAB_PROJECT` is not set, the script attempts to detect the project from
`git remote get-url origin`. Set the variable explicitly when you are not in a
git repository or when you want to target a different project.

## Quick Start

Export your environment variables, then run a read command with `--fields`.

```bash
export GITLAB_URL="https://gitlab.com"
export GITLAB_TOKEN="glpat-..."
export GITLAB_PROJECT="group/project"

python scripts/gitlab.py mr-list opened --fields iid,title,author.name
```

Read pipeline jobs for a known pipeline:

```bash
python scripts/gitlab.py pipeline-jobs 12345 --fields id,name,status,stage
```

| `mr-notes`      | `<mr-iid> [max]`           | List merge request notes, excluding system notes when using `--fields` |
| `pipeline-get`  | `<pipeline-id>`            | Get one pipeline by numeric ID                                         |
| `pipeline-run`  | `<branch-or-tag>`          | Trigger a pipeline for a branch or tag                                 |

## Script Reference

List recent open merge requests:

```bash
python scripts/gitlab.py mr-list opened --fields iid,title,author.name,user_notes_count
```

Get one merge request:

```bash
python scripts/gitlab.py mr-get 42 --fields iid,title,state,source_branch,target_branch
```

Create a merge request from inline JSON:

```bash
python scripts/gitlab.py mr-create '{
  "source_branch": "feature/add-auth",
  "target_branch": "main",
  "title": "feat(auth): add OAuth login"
}'
```

Add a merge request comment from standard input:

```bash
echo "CI passed. Ready for review." | python scripts/gitlab.py mr-comment 42
```

Inspect a failed pipeline:

```bash
python scripts/gitlab.py pipeline-get 12345 --fields id,status,web_url
python scripts/gitlab.py pipeline-jobs 12345 --fields id,name,status,stage
python scripts/gitlab.py job-log 67890
```

## Troubleshooting

| Symptom                                          | Cause                                         | Resolution                                                  |
|--------------------------------------------------|-----------------------------------------------|-------------------------------------------------------------|
| `GITLAB_URL is not set`                          | Required environment variable missing         | Export `GITLAB_URL` before running the script               |
| `GITLAB_TOKEN is not set`                        | Missing personal access token                 | Create a token with API access and export `GITLAB_TOKEN`    |
| `cannot parse git remote URL`                    | Project autodetection failed                  | Set `GITLAB_PROJECT` explicitly                             |
| `HTTP 401` or `HTTP 403`                         | Token is invalid or lacks access              | Verify token scope and project permissions                  |
| `HTTP 404`                                       | Wrong project, MR IID, pipeline ID, or job ID | Verify `GITLAB_PROJECT` and confirm the numeric identifiers |
| `expected numeric ID`                            | Non-numeric value passed to an ID argument    | Use project MR IID values and numeric pipeline or job IDs   |
| `python3 is required` or syntax errors on launch | Unsupported interpreter                       | Run the script with Python 3.11 or later                    |

GitLab uses MR IIDs such as `!42` inside a project. This skill expects the
numeric IID, not the global merge request ID.
