GitLab Skill

This skill provides GitLab integration using the official glab CLI tool. A Python wrapper script produces markdown-formatted output for read/view operations. Action commands (create, merge, close, comment) should use glab directly.

Prerequisites

Install glab CLI: https://gitlab.com/gitlab-org/cli#installation

Quick install:

# macOS
brew install glab

# Linux (Debian/Ubuntu)
sudo apt install glab

# Fedora/RHEL/CentOS
sudo dnf install glab

# Windows
winget install GLab.GLab

Authentication

# Authenticate with GitLab
glab auth login

# Verify authentication
glab auth status

Supports GitLab.com, GitLab Dedicated, and GitLab Self-Managed instances.
See GitLab CLI Authentication for details.

Script Usage

The wrapper script (scripts/gitlab.py) formats output as markdown. Use it for read/view operations to get agent-consumable output. Use glab directly for action commands (create, merge, close, comment).

# Check glab CLI is installed and authenticated
python scripts/gitlab.py check

# Issues
python scripts/gitlab.py issues list --repo GROUP/REPO
python scripts/gitlab.py issues view 123 --repo GROUP/REPO

# Merge Requests
python scripts/gitlab.py mrs list --repo GROUP/REPO
python scripts/gitlab.py mrs view 456 --repo GROUP/REPO

# Pipelines
python scripts/gitlab.py pipelines list --repo GROUP/REPO
python scripts/gitlab.py pipelines view 123456 --repo GROUP/REPO

# Repositories
python scripts/gitlab.py repos list
python scripts/gitlab.py repos view GROUP/REPO

All commands support --limit N for list commands (default 30).

Commands (Direct glab Usage)

For action commands, use glab directly:

Issues

glab issue list                    # List issues
glab issue view 123                # View issue details
glab issue create                  # Create new issue
glab issue note 123                # Add comment
glab issue close 123               # Close issue
glab issue update 123 --label bug  # Edit issue

Full reference: glab issue

Merge Requests

glab mr list                       # List merge requests
glab mr view 456                   # View MR details
glab mr create                     # Create new MR
glab mr approve 456                # Approve MR
glab mr merge 456                  # Merge MR
glab mr checkout 456               # Checkout MR branch
glab mr diff 456                   # View MR diff
glab mr note 456                   # Add comment to MR

Full reference: glab mr

Pipelines & CI/CD

glab ci list                       # List pipelines
glab ci view 123456                # View pipeline details
glab ci run                        # Trigger pipeline
glab ci trace                      # Watch pipeline logs
glab ci retry 123456               # Retry failed pipeline
glab ci status                     # Show pipeline status

Repositories

glab repo list                     # List repositories
glab repo view GROUP/REPO          # View repository
glab repo create                   # Create repository
glab repo clone GROUP/REPO         # Clone repository
glab repo fork GROUP/REPO          # Fork repository

Releases

glab release list                  # List releases
glab release view v1.0.0           # View release details
glab release create v1.0.0         # Create release
glab release delete v1.0.0         # Delete release

Examples

Daily MR Review

# List MRs assigned to you
glab mr list --assignee=@me

# Review a specific MR
glab mr view 456
glab mr diff 456
glab mr approve 456

Create Issue and Link MR

# Create issue
glab issue create --title "Bug: Login fails" --description "Description" --label bug

# Create MR that closes it
glab mr create --title "Fix login bug" --description "Closes #123"

Monitor CI Pipeline

# Check current pipeline status
glab ci status

# Watch pipeline logs in real-time
glab ci trace

# Retry failed jobs
glab ci retry

See common-workflows.md for more examples.

Advanced Usage

JSON Output for Scripting

# Get JSON output
glab issue list --output json

# Process with jq
glab mr list --output json | jq '.[] | "\(.iid): \(.title)"'

GitLab API Access

For operations not covered by glab commands:

# Make authenticated API request
glab api projects/:id/issues

# POST request
glab api projects/:id/issues -X POST -f title="Issue" -f description="Text"

# Process response
glab api projects/:id | jq '.star_count'

Full reference: glab api

Aliases for Frequent Operations

# Create shortcuts
glab alias set mrs 'mr list --assignee=@me'
glab alias set issues 'issue list --assignee=@me'
glab alias set pipelines 'ci list'

# Use them
glab mrs
glab issues
glab pipelines

Configuration

# View configuration
glab config get

# Set default editor
glab config set editor vim

# Set default Git protocol
glab config set git_protocol ssh

Configuration stored in ~/.config/glab-cli/config.yml

Model Guidance

This skill wraps an official CLI. A fast, lightweight model is sufficient.

Troubleshooting

# Check authentication
glab auth status

# Re-authenticate
glab auth login

# Enable debug logging
DEBUG=1 glab issue list

# Check glab version
glab version

Summary

The GitLab skill uses the official glab CLI with a Python wrapper for markdown-formatted output on read/view commands.

Quick start:

1. Install: brew install glab (or equivalent for your OS)
2. Authenticate: glab auth login
3. Verify: python scripts/gitlab.py check
4. Read: python scripts/gitlab.py issues list --repo GROUP/REPO
5. Write: glab issue create, glab mr create, etc. (use glab directly)
