Managing Git Workflow

Overview

Turn an explicit Git or pull-request request into one bounded operation. Resolve scripts/skill-set-git relative to the directory containing this SKILL.md, then invoke that absolute path directly for all Git and GitHub activity. Do not depend on a host-specific plugin-root environment variable or a shell variable persisting across tool calls. References use <git-runner> as a non-executable placeholder; replace it with the resolved absolute path in every invocation. The runner returns JSON, preserves shell metacharacters through file arguments, and applies index and remote compare-and-swap checks before mutation.

Authorization Boundary

Inspection is read-only. Run inspect whenever repository state may have changed.

Treat each mutation as a separate capability:

• commit: authorized only by a request to create a commit; never pushes.
• push: authorized only by a request to push; publishes existing commits only.
• pr-create: authorized only by a request to create a PR; may push existing commits when the PR branch is not current remotely.

Do not infer one capability from another. A commit request does not authorize push, and a push request does not authorize creating a commit. Never execute direct Git or GitHub commands from this skill.

Workflow Selection

Common Contract

1. Parse successful stdout as one JSON object.
2. Parse a nonzero command's stderr as a recoverable JSON error.
3. Stop on stale index_fingerprint, changed remote SHA, behind/diverged history, or ambiguous scope.
4. Use --dry-run before a mutation when the requested scope is not already fully confirmed.
5. Ask input-prepare for a managed path, replace its exact SKILL_SET_INPUT_REPLACE_ME sentinel through the scoped Edit capability, then pass it as --message-file or --body-file.
6. Preserve staged, unstaged, and untracked distinctions in every user-facing summary.

Commit Scope Rules

• With no paths, commit the current index only.
• With user-named paths, pass one --path per path. The runner rejects staged paths outside that scope.
• Pass --all only when the user explicitly requested every current change.
• If the index is empty and no scope was named, ask for paths. Do not infer them from nearby files.
• Generate the message from commit_context.staged_diff or the staged_preview returned by commit dry-run, not from a general working-tree summary.

Language Detection

Use the user's language for conversation. For commit messages and PR titles/bodies, follow an explicit artifact-language instruction or the repository's language policy first; otherwise use the user's language, then recent repository convention, then English. Match recent commit style without overriding the applicable language policy. Keep commands, paths, and technical identifiers exact.

Safety Invariants

• Never publish from commit.
• Never create a commit from push or pr-create.
• Never include dirty files in a PR implicitly.
• Require explicit confirmation before proceeding with dirty files excluded from a new PR.
• Return an existing PR URL instead of creating a duplicate.
• Use the committed PR range origin/<base>...HEAD reported by the runner.
• Do not resolve divergence or remote races automatically; report the recovery decision to the user.
• If the user cancels after preparing text, remove its managed allocation with input-discard.
• Never pass an unchanged sentinel; the runner rejects it before any commit, push, or PR creation.
