Structure

Each skill lives in its own folder and exposes an uppercase SKILL.md file:

plugins/gitlab/
├── .claude-plugin/plugin.json
├── README.md
└── skills/
    ├── gitlab-mr-list-open/
    │   └── SKILL.md
    ├── gitlab-mr-create/
    │   └── SKILL.md
    ├── gitlab-mr-diff/
    │   └── SKILL.md
    ├── gitlab-mr-checkout/
    │   └── SKILL.md
    ├── gitlab-mr-assign-reviewer/
    │   └── SKILL.md
    ├── gitlab-mr-line-note/
    │   └── SKILL.md
    └── gitlab-mr-summary/
        └── SKILL.md

Setup

The skills select their access method from the GITLAB_TOKEN environment variable:

Condition	Method used
GITLAB_TOKEN is set	GitLab REST API
GITLAB_TOKEN is not set	GitLab CLI (glab)

GitLab CLI

Install and authenticate glab if you want the CLI path:

# macOS
brew install glab

# Windows
winget install glab

# Login to a self-hosted instance
glab auth login --hostname gitlab.example.com

REST API

Set these environment variables if you want the API path:

export GITLAB_HOST="https://gitlab.example.com"
export GITLAB_TOKEN="your_personal_access_token"

The token should have the api scope. read_api is enough for read-only operations.

Install

Claude Code

Install the whole plugin, or copy individual skill folders from skills/ into .claude/skills/.

GitHub Copilot

Install the whole plugin, or copy individual skill folders from skills/ into .github/skills/ in a repository or ~/.copilot/skills/ for user-wide use.

Usage Examples

/gitlab-mr-list-open
/gitlab-mr-create --source feature/login --target main --title "Add login page"
/gitlab-mr-diff 42
/gitlab-mr-checkout 42
/gitlab-mr-assign-reviewer 42
/gitlab-mr-line-note 42 src/auth.go 87 "Consider using a constant here."
/gitlab-mr-summary 42

Troubleshooting

Problem	Solution
401 Unauthorized	Check GITLAB_TOKEN and required scopes
404 Not Found	Verify GITLAB_HOST and the current repository remote
glab not found	Install glab or set GITLAB_TOKEN
Inline note fails	The target line may not be part of the diff
Wrong tool selected	Unset GITLAB_TOKEN to force the CLI path
