Git Platform Detection & Command Mapping

Overview

Cross-platform abstraction for git forge operations. Detects whether the current project uses GitHub, GitLab, or Bitbucket, and provides equivalent CLI commands for each platform.

The SessionStart hook (detect-git-platform.sh) automatically injects the detected platform into session context. This skill provides the command reference for translating operations across platforms.

When To Use

• Before running gh, glab, or forge API commands
• When a skill or command needs to create issues, PRs/MRs, or post comments
• When writing CI/CD configuration
• Any time forge-specific CLI commands appear in a workflow

When NOT To Use

• Local-only git operations (git commit, git branch, etc.)
• Projects without a hosted git remote

Platform Detection

Detection is automatic via the SessionStart hook. The session context will contain:

git_platform: github|gitlab|bitbucket, cli: gh|glab, mr_term: pull request|merge request

If you need to re-detect manually:

# Check remote URL
git remote get-url origin 2>/dev/null

# Check file markers
ls -d .github/ .gitlab-ci.yml bitbucket-pipelines.yml 2>/dev/null

# Check CLI availability
command -v gh && echo "GitHub CLI available"
command -v glab && echo "GitLab CLI available"

Quick Command Reference

Operation	GitHub (gh)	GitLab (glab)
View issue	gh issue view N --json title,body,labels	glab issue view N
List issues	gh issue list --json number,title	glab issue list
Create issue	gh issue create --title "T" --body "B"	glab issue create --title "T" --description "B"
Close issue	gh issue close N	glab issue close N
Comment on issue	gh issue comment N --body "msg"	glab issue note N --message "msg"
View PR/MR	gh pr view N	glab mr view N
Create PR/MR	gh pr create --title "T" --body "B"	glab mr create --title "T" --description "B"
List PR/MR comments	gh api repos/O/R/pulls/N/comments	glab mr note list N
Current PR/MR	gh pr view --json number	glab mr view --json iid
Resolve threads	gh api graphql	glab api graphql
Repo info	gh repo view --json owner,name	glab repo view

For Bitbucket: No standard CLI exists. Use REST API (curl) or the web interface. See command-mapping module for API equivalents.

Terminology

Concept	GitHub	GitLab	Bitbucket
Code review unit	Pull Request (PR)	Merge Request (MR)	Pull Request (PR)
CI configuration	.github/workflows/*.yml	.gitlab-ci.yml	bitbucket-pipelines.yml
Default branch	main	main	main
Review comments	PR review comments	MR discussion notes	PR comments

Important: When the platform is GitLab, always say "merge request" (not "pull request") in user-facing output, commit messages, and comments.

Integration Pattern

Skills that perform forge operations should:

1. Declare dependencies: [leyline:git-platform]
2. Check the session context for git_platform:
3. Use the command mapping table above
4. Fall back gracefully if CLI is unavailable

# Example skill instruction pattern:

## Step N: Create PR/MR

Use the detected platform CLI (check session context for `git_platform`):
- **GitHub**: `gh pr create --title "..." --body "..."`
- **GitLab**: `glab mr create --title "..." --description "..."`
- **Bitbucket**: Create via web interface

Detailed Resources

• Full command mapping: See modules/command-mapping.md for complete API equivalents, GraphQL queries, and Bitbucket REST API patterns
• Authentication: See Skill(leyline:authentication-patterns) for ensure_auth github|gitlab

Exit Criteria

• Platform detected (or explicitly unknown)
• Correct CLI tool used for all forge operations
• Platform-appropriate terminology in user-facing output
