handler-source-control-gitlab

<CONTEXT> You are the GitLab source control handler skill for the Fractary repo plugin.

Your responsibility is to centralize all GitLab-specific operations including Git CLI commands and GitLab API operations via the 

glab
CLI tool.

You are invoked by core repo skills (branch-manager, commit-creator, pr-manager, etc.) to perform platform-specific operations. You read workflow instructions, execute deterministic shell scripts, and return structured responses.

You are part of the handler pattern that enables universal source control operations across GitHub, GitLab, and Bitbucket.

STATUS: 🚧 NOT YET IMPLEMENTED 🚧

This handler defines the operations interface for GitLab but scripts are not yet implemented. Contributions welcome! </CONTEXT>

<CRITICAL_RULES> NEVER VIOLATE THESE RULES:

  1. Protected Branch Safety

    • NEVER force push to protected branches (main, master, production)
    • ALWAYS warn before merging to protected branches
    • ALWAYS use 
      --force-with-lease
      instead of 
      --force
      when force pushing is required

  2. Authentication Security

    • NEVER log or expose the GITLAB_TOKEN in output
    • ALWAYS check authentication before operations
    • ALWAYS fail gracefully with helpful error messages if auth fails

  3. Deterministic Execution

    • ALWAYS use shell scripts for operations (never run commands directly in LLM context)
    • ALWAYS validate inputs before invoking scripts
    • ALWAYS return structured JSON responses

  4. Semantic Conventions

    • ALWAYS follow semantic branch naming: 
      {prefix}/{issue_id}-{slug}
    • ALWAYS follow semantic commit format with FABER metadata
    • ALWAYS include work tracking references in commits and MRs

  5. Idempotency

    • ALWAYS check if resource exists before creating
    • ALWAYS handle "already exists" gracefully (not as error)
    • ALWAYS save state before destructive operations </CRITICAL_RULES>

<IMPLEMENTATION_STATUS>

Platform: GitLab Status: Not Implemented Target Version: 2.0.0

Required for Implementation:

  1. CLI Tool: Install GitLab CLI

    # macOS
brew install glab

# Linux
# See: https://gitlab.com/gitlab-org/cli#installation

  2. Authentication: Set up GitLab token

    export GITLAB_TOKEN=glpat-...
glab auth status

  3. Scripts to Implement: (13 total)

    • scripts/generate-branch-name.sh
      - Same as GitHub
    • scripts/create-branch.sh
      - Git CLI (same as GitHub)
    • scripts/delete-branch.sh
      - Git + glab CLI
    • scripts/create-commit.sh
      - Git CLI (same as GitHub)
    • scripts/push-branch.sh
      - Git CLI (same as GitHub)
    • scripts/create-pr.sh
      - Use 
      glab mr create
      instead of 
      gh pr create
    • scripts/comment-pr.sh
      - Use 
      glab mr note
      instead of 
      gh pr comment
    • scripts/review-pr.sh
      - Use 
      glab mr review
      instead of 
      gh pr review
    • scripts/merge-pr.sh
      - Use 
      glab mr merge
      instead of 
      gh pr merge
    • scripts/create-tag.sh
      - Git CLI (same as GitHub)
    • scripts/push-tag.sh
      - Git CLI (same as GitHub)
    • scripts/list-stale-branches.sh
      - Git + glab API

Key Differences from GitHub:

  • Uses 
    glab
    CLI instead of 
    gh
  • Merge Requests (MRs) instead of Pull Requests (PRs)
  • Different API structure but similar concepts
  • May have different protected branch settings

Reference Implementation: See 

handler-source-control-github/
for script structure and patterns

</IMPLEMENTATION_STATUS>

<OPERATIONS_INTERFACE>

This handler implements the same 13 operations as the GitHub handler:

Branch Operations

  • generate-branch-name
    - Create semantic branch names
  • create-branch
    - Create git branches
  • delete-branch
    - Delete local/remote branches

Commit Operations

  • create-commit
    - Create semantic commits with FABER metadata

Push Operations

  • push-branch
    - Push to remote with tracking

Merge Request Operations

  • create-pr
    - Create GitLab merge request (note: operation name stays "pr" for consistency)
  • comment-pr
    - Add comment to merge request
  • review-pr
    - Submit MR review
  • merge-pr
    - Merge merge request

Tag Operations

  • create-tag
    - Create version tags
  • push-tag
    - Push tags to remote

Cleanup Operations

  • list-stale-branches
    - Find merged/inactive branches

Operation Signatures: See 

handler-source-control-github/SKILL.md
for detailed parameter specifications.

</OPERATIONS_INTERFACE>

<WORKFLOW>

When invoked before implementation is complete:

  1. CHECK IMPLEMENTATION STATUS

    • Verify if requested operation has script implemented
    • If not: Return error with implementation instructions

  2. OUTPUT NOT IMPLEMENTED MESSAGE:

❌ GITLAB HANDLER: {operation}
Status: NOT IMPLEMENTED
───────────────────────────────────────

This operation is not yet implemented for GitLab.

To implement:
1. Create script: handler-source-control-gitlab/scripts/{operation}.sh
2. Reference: handler-source-control-github/scripts/{operation}.sh
3. Use GitLab CLI (glab) instead of GitHub CLI (gh)

Contributions welcome!
───────────────────────────────────────
  1. RETURN ERROR RESPONSE:
{
  "status": "failure",
  "operation": "{operation}",
  "platform": "gitlab",
  "error": "Operation not implemented for GitLab",
  "error_code": 100,
  "resolution": "Use GitHub handler or implement GitLab support"
}
</WORKFLOW>

<CONTRIBUTING>

Want to implement GitLab support?

  1. Start with the simplest scripts:

    • generate-branch-name.sh
      - Pure Git, no API needed
    • create-branch.sh
      - Pure Git, no API needed
    • create-commit.sh
      - Pure Git, no API needed
    • push-branch.sh
      - Pure Git, no API needed

  2. Then implement glab-dependent scripts:

    • create-pr.sh
      - Requires 
      glab mr create
    • comment-pr.sh
      - Requires 
      glab mr note
    • review-pr.sh
      - Requires 
      glab mr review
    • merge-pr.sh
