Git Workflow Skill

Create properly scoped git commits for task operations.

Context Loading

Load context on-demand when needed:

• @.claude/context/core/standards/git-safety.md - Git safety rules and best practices
• @.claude/context/index.md - Full context discovery index

Trigger Conditions

This skill activates when:

• Task status changes (research, plan, implement complete)
• Artifacts are created
• Task lifecycle operations occur

Commit Message Formats

Task Operations

Operation	Format	CI Triggered
Create task	task {N}: create {title}	No
Complete research	task {N}: complete research	No
Create plan	task {N}: create implementation plan	No
Complete phase	task {N} phase {P}: {phase_name}	No
Complete task	task {N}: complete implementation	No
Complete task (with CI)	task {N}: complete implementation [ci]	Yes
Revise plan	task {N}: revise plan (v{V})	No

System Operations

Operation	Format
Archive tasks	todo: archive {N} completed tasks
Error fixes	errors: create fix plan for {N} errors
Code review	review: {scope} code review
State sync	sync: reconcile TODO.md and state.json

Execution Flow

1. Receive commit request:
   - operation_type
   - task_number (if applicable)
   - scope (files to include)
   - message_template

2. Stage appropriate files:
   - git add {scope}

3. Create commit:
   - Format message
   - Add co-author
   - Execute commit

4. Verify success:
   - Check exit code
   - Log result

5. Return result

Commit Scope Rules

Task-Specific Commits

Include only task-related files:

specs/TODO.md
specs/state.json
specs/{N}_{SLUG}/**

Implementation Commits

Include source files modified:

Logos/**/*.lean  (for Lean tasks)
src/**/*         (for general tasks)

Phase Commits

Scope to phase changes only:

Files modified in that phase
Updated plan with phase status

Safety Checks

Before Commit

1. git status - verify staged files
2. Check no sensitive files staged (.env, credentials)
3. Verify commit message format

Never Run

• git push --force
• git reset --hard (without explicit request)
• git rebase -i

Message Template

CI Triggering

Overview

CI is skipped by default on push events. To trigger CI, add [ci] marker to the commit message.

trigger_ci Parameter

When creating commits, the trigger_ci parameter controls whether CI runs:

Value	Behavior	Use Case
false (default)	No CI marker added	Routine commits, research, planning
true	Append [ci] to message	Lean changes, implementation completion

CI Decision Criteria

Trigger CI (trigger_ci: true) when:

• Lean files modified (.lean) - Ensures build passes
• Implementation completed - Final verification before merge
• CI configuration changed (.github/workflows/) - Validate workflow changes
• Mathlib dependencies updated (lakefile.lean, lake-manifest.json) - Ensure compatibility
• Critical bug fixes - Verify fix works

Skip CI (default) when:

• Documentation changes only (.md files)
• Research/planning artifacts
• Configuration changes (non-CI)
• Routine task management operations

Commit Message with CI Marker

task {N}: complete implementation [ci]

When CI Always Runs

CI runs regardless of marker on:

• Pull request events (all PRs run CI)
• Manual workflow_dispatch trigger
• Commits with [ci] marker

Execution Commands

Standard Commit

git add {files}
git commit -m "$(cat <<'EOF'
{message}

Co-Authored-By: Claude Opus 4.5 <[e-mail]>
EOF
)"

Task Commit

git add specs/
git commit -m "$(cat <<'EOF'
task {N}: {action}

Co-Authored-By: Claude Opus 4.5 <[e-mail]>
EOF
)"

Return Format

{
  "status": "completed|failed",
  "summary": "Created commit: {short_message}",
  "commit_hash": "abc123",
  "files_committed": [
    "path/to/file1",
    "path/to/file2"
  ],
  "message": "Full commit message",
  "ci_triggered": true|false
}

Error Handling

Nothing to Commit

{
  "status": "committed",
  "summary": "No changes to commit",
  "commit_hash": null
}

Pre-Commit Hook Failure

{
  "status": "failed",
  "error": "Pre-commit hook failed",
  "recovery": "Fix issues and retry (do not use --no-verify)"
}

Git Error

{
  "status": "failed",
  "error": "Git command failed: {error}",
  "recovery": "Check git status and resolve manually"
}

Non-Blocking Behavior

Git failures should NOT block task operations:

• Log the failure
• Continue with task
• Report to user that commit failed
• Task state is preserved regardless
