Git Commit
Create a single, well-crafted git commit from the current working tree changes.
Workflow
Step 1: Gather context
Run this command to gather all context:
printf '=== STATUS ===\n'; git status; printf '\n=== DIFF ===\n'; git diff HEAD; printf '\n=== BRANCH ===\n'; git branch --show-current; printf '\n=== LOG ===\n'; git log --oneline -10; printf '\n=== DEFAULT_BRANCH ===\n'; git rev-parse --abbrev-ref origin/HEAD 2>/dev/null || echo '__DEFAULT_BRANCH_UNRESOLVED__'
The remote default branch value returns something like origin/main. Strip the origin/ prefix to get the branch name. If it returned __DEFAULT_BRANCH_UNRESOLVED__ or a bare HEAD, try:
gh repo view --json defaultBranchRef --jq '.defaultBranchRef.name'
If both fail, fall back to main.
If git status shows a clean working tree (no staged, modified, or untracked files), report that there is nothing to commit and stop.
If the current branch is empty (detached HEAD), explain that a branch is required before committing if the user wants this work attached to a branch. Ask whether to create a feature branch now.
- If the user chooses to create a branch, derive the name from the change content, create it with
git checkout -b <branch-name>, then run git branch --show-current again and use that result as the current branch name for the rest of the workflow.
- If the user declines, continue with the detached HEAD commit.
Step 2: Determine commit message convention
Follow this priority order:
- Repo conventions already in context -- If project instructions (AGENTS.md or similar) are already loaded and specify commit message conventions, follow those. Do not re-read these files; they are loaded at session start.
- Recent commit history -- If no explicit convention is documented, examine the 10 most recent commits from Step 1. If a clear pattern emerges (e.g., conventional commits, ticket prefixes, emoji prefixes), match that pattern.
- Default: conventional commits -- If neither source provides a pattern, use conventional commit format:
type(scope): description where type is one of feat, fix, docs, refactor, test, chore, perf, ci, style, build.
When using conventional commits, choose the type that most precisely describes the change (the type list above). Where fix: and feat: both seem to fit, default to fix:: a change that remedies broken or missing behavior is fix: even when implemented by adding code. Reserve feat: for capabilities the user could not previously accomplish. Other types remain primary when they fit better. The user may override for a specific change.
Step 3: Consider logical commits
Before staging everything together, scan the changed files for naturally distinct concerns. If modified files clearly group into separate logical changes (e.g., a refactor in one directory and a new feature in another, or test files for a different change than source files), create separate commits for each group.
Keep this lightweight:
- Group at the file level only -- do not use
git add -p or try to split hunks within a file.
- If the separation is obvious (different features, unrelated fixes), split. If it's ambiguous, one commit is fine.
- Two or three logical commits is the sweet spot. Do not over-slice into many tiny commits.
Step 4: Stage and commit
If the current branch from the context above is main, master, or the resolved default branch from Step 1, automatically create a feature branch before committing. Derive the branch name from the change content, create it with git checkout -b <branch-name>, run git branch --show-current to confirm, and use the new branch as the current branch for the rest of the workflow. Do not ask whether to branch -- committing on the default branch is not an option here.
Write the commit message:
- Subject line: Concise, imperative mood, focused on why not what. Follow the convention determined in Step 2.
- Body (when needed): Add a body separated by a blank line for non-trivial changes. Explain motivation, trade-offs, or anything a future reader would need. Omit the body for obvious single-purpose changes.
For each commit group, stage and commit in a single call. Prefer staging specific files by name over git add -A or git add . to avoid accidentally including sensitive files (.env, credentials) or unrelated changes. Use a heredoc to preserve formatting:
git add file1 file2 file3 && git commit -m "$(cat <<'EOF'
type(scope): subject line here
Optional body explaining why this change was made,
not just what changed.
EOF
)"
Step 5: Confirm
Run git status after the commit to verify success. Report the commit hash(es) and subject line(s).
