Git Expert (Semantic Stack)
Core Mandates
- Discovery First: Before using any VCS tool, check for
.git/. If present and.jj/is absent, usegitas the primary interface. - Semantic Insight: Use
sem difffor entity-level changes (functions, classes) andgit dft(difftastic) for structural diffing. - Clean History: Maintain atomic, logical commits. One change = one commit.
Technical Standards
1. Advanced Diffing
| Tool | Task | Command | Purpose |
| :--- | :--- | :--- | :--- |
| sem | sem diff | sem diff | Entity-level changes (functions/classes). |
| difftastic | git dft | git dft | Structural diffing that ignores syntax noise. |
| delta | git log -p | git log -p | Colorized diffing for history review. |
2. Semantic Merge (Weave)
- Automatic:
weaveis configured globally as a merge driver. Most merges use it automatically. - Claiming Entities: For high-contention files, use
weave claim <entity>before editing to prevent merge conflicts. Runweave release <entity>after committing. - Conflicts: Use
weave summaryto parse structured conflict markers.
3. GitHub CLI (gh)
- PR Management:
gh pr create,gh pr checkout,gh pr list. - Repo Info:
gh repo view,gh repo clone. - Issue Tracking:
gh issue list,gh issue view.
4. Git Standards
- Commit Messages: Use
git-commitskill for message format and rules. - Exclusion: Use
.git/info/excludefor agent files (ai/, .tasks/) as pergit-local-exclude.
Anti-Rationalization
| Excuse | Reality |
| :--- | :--- |
| "Line diff is fine" | You're missing the structural context. Use sem or dft. |
| "I'll use the git UI" | The gh CLI is faster and more automatable for agents. |
| "I'll use .gitignore" | Use git-local-exclude for files only YOU (the agent) use. |
| "I'll claim later" | If multiple agents are working, weave claim is essential to prevent conflicts. |
