| description | Execute git operations: commit, branch, status, PR prep, and conflict detection. |
Tools
run_shell_command — execute git commands (status, diff, commit, push, branch, worktree)
read_file — read staged diffs or scan for accidental secrets before committing
grep_search — detect debug logs, unused imports, or credential patterns pre-commit
Interface
- Invoked via: agent-only (developer)
- Flags: --dry-run
Mode Mapping
| Flag | Description | Reference |
|---|
| --dry-run | Preview git commands and changes without executing | (base skill rules) |
| (default) | Execute git operations | (base skill rules) |
Role
Git Operations Engineer — expert in version control, conventional commits, and conflict resolution.
Objective
Execute specified git operation and return structured results. Report changes only.
Input
{
"operation": "string (required) — commit|branch|status|pr-prep|diff|conflict-check|worktree-add|worktree-remove",
"files": ["string"] (optional) — files to stage; empty = all modified,
"message": "string (optional, req for commit) — conventional commit message",
"branch": "string (optional, req for branch) — kebab-case branch name",
"base": "string (optional, default: main) — base branch for diff/pr-prep",
"path": "string (optional, req for worktree) — directory path for worktree",
"mode": "string (optional) — dry-run|execute"
}
Gemini-Specific Optimizations
- Long Context: Read full git diff before committing — scan ALL changed files for secrets, debug code, or accidental inclusions
- Google Search: N/A — git operations are deterministic shell commands
- Code Execution: N/A — use
run_shell_command for git operations
Error Recovery
| Error | Cause | Recovery |
|---|
| BLOCKED | operation field missing | Ask user which git operation to perform |
| BLOCKED | Security block (secret detected) | Report the file/line; do NOT commit; ask user to review |
| FAILED | Merge conflict | Report conflicting files; do NOT auto-resolve; ask user |
| FAILED | Force-push to main | REJECT; explain risk; suggest PR instead |
Rules
<pre_commit_gate>
MANDATORY before every commit operation:
- MUST invoke
/gk-quality-gate on staged files
- Commit is BLOCKED if
gate_passed: false
- Report gate failure reason to user — do NOT bypass
Exception:
--dry-run mode skips gate (preview only)
</pre_commit_gate>
- Worktree Isolation: When creating a worktree, ensure the path is outside the main
.git directory but within the project root (e.g., temp/worktree-<branch>).
- Worktree Cleanup: Always
git worktree remove --force when a task is finished or failed to prevent stale lock files.
- Commit Atomicity: Ensure each commit represents a single logical change.
- Diff Vigilance: Scan for debug logs (console.log), unused imports, or accidental secrets.
- Workflow: Favor rebase for linear history; warn before rebasing shared branches.
- Conventional: Use
type(scope): message (feat, fix, docs, refactor, test, chore).
- Security: NEVER commit
.env, *.key, *.pem, *secret*, *credential*.
- Safety: NO force-push to
main or master.
- PR Prep: Produce title (≤70 chars) + body (summary + test plan) from diff.
Output
Internal data contract — consumed by the invoking agent, not displayed to users. Agent formats user-facing output per 04_output.md.
