--- name: git-commit-conventional description: Create Conventional Commit messages and execute safe git commits from working tree changes. Use when users ask to create a commit, write a conventional commit message, split broad changes into multiple commits, stage only parts of files, run pre-commit before committing, or perform a quick commit-time quality review with severity guardrails. --- # Git Commit Conventional ## Overview Generate clear Conventional Commit messages, decide commit grouping, run commit-time checks, and create commit(s) safely. ## Context Marker Always begin your response with all active emoji markers, in the order they were introduced. Format: `"\n"` The marker for this skill is: `🎯` ## Workflow 1. Inspect repository context: - Run `git log -n 20 --pretty=format:%s` for subject style context only. - Run `git status`. 1. Select the diff to analyze: - If staged changes exist, use `git diff --staged` and ignore unstaged changes. - If nothing is staged, run `git diff` and ask whether to stage all or specific files before committing. 1. Evaluate commit pressure using balanced thresholds: - Count changed files and changed lines from the active diff context. - Classify zone: - `green`: `<=5` files and `<=150` changed lines. - `yellow`: `6-12` files or `151-400` changed lines. - `red`: `>12` files or `>400` changed lines. - Apply zone behavior: - `green`: proceed with normal commit boundary analysis. - `yellow`: recommend splitting and record a risk note if user chooses a single commit. - `red`: require a split plan before proceeding; only continue single-commit flow with explicit user override. 1. Decide single versus multiple commits with an explicit framework: - Check logical separation: split when changes serve multiple distinct goals. - Check file-type mixing: split documentation changes from code changes when they can stand alone. - Check implementation versus tests: split when test updates are independent from implementation updates. - Check formatting versus logic: split formatting-only churn from behavior changes. - Check dependencies versus behavior: split dependency and tooling updates from code behavior changes. - Check mixed-purpose hunks in the same file: split by hunk when one file contains unrelated intents (for example, rename plus refactor). - Check size and reviewability: consider splitting broad changes (for example, over roughly 150 changed lines) by module or feature. - Check issue/feature boundaries: split when multiple bugs or features are addressed in one diff. - Keep together when changes are small and focused on one purpose. - Keep together when changes are tightly coupled and splitting would create non-functional or misleading history. - Keep together when all changes are part of one coherent refactor. 1. Stage changes intentionally for the selected commit boundary: - Use `git add -p` to stage only relevant hunks when a file mixes logical changes. - Use `git add -e` only when hunk editing is required and apply minimal edits. - After staging, verify scope with `git diff --staged` and `git diff` before proceeding. - If partial staging would create a broken intermediate commit, keep dependent hunks together. 1. Run a concise quality review before committing: - Check correctness, maintainability, security, performance, and tests. - Classify findings by severity: Critical, High, Medium, Low. - Present findings using this structure: Executive Summary; Issues by severity with file/line references; Suggested fixes with brief examples; Positive observations; Actionable next steps. - If any Critical or High issue is found, stop and request explicit user confirmation before committing. 1. If `.pre-commit-config.yaml` exists, run `pre-commit run`: - Never bypass hooks. - For trivial fixes, apply changes, restage files, and rerun hooks with a max of 2 retries. - Stop retrying when hooks pass, when retries are exhausted, or when reruns make no additional file changes. - If hooks still fail after retries, stop and ask the user for direction. - For non-trivial fixes, present the proposed fix to the user and get approval before applying and proceeding. - Treat formatting-only or whitespace-only hook edits as trivial auto-fixes. - Track every auto-fixed file and the hook that changed it. 1. Generate commit message(s) in strict Conventional Commit format: - Subject must match `(): ` or `: `. - If subject format is invalid, regenerate until format is valid. - Keep subject imperative and concise. - If the change is breaking, use `!` and add explicit breaking-change explanation in the body and/or footer (`BREAKING CHANGE: ...`). - Include body to document context and rationale. - Only exclude a body when the changes are very, very small. 1. Apply AI attribution policy before each commit: - Always include a footer-only `Co-Authored-By` attribution on agent-created commits. - Never mention AI generation in the subject or body. - Use best effort self-identification to determine AI name and email from runtime/model self-awareness metadata. - If email is not readily available, use `no-reply@example.com`. - If name is not readily available, use `AI Assistant`. - Never block commit flow by asking the user for attribution identity. 1. Use deterministic output contract for single-commit and multi-commit runs: - Before committing, present `Commit Plan`: - `commit_count` - `threshold_zone_encountered` - `boundaries_rationale` - `scope_per_commit` - Before each commit, present `Per-Commit Preview`: - `index` (`i/N`) - `staged_files` - `subject` - `body_present` - `footers` - `checks_to_run` - After each commit, present `Per-Commit Result`: - `hash` - `subject` - `hook_result` - `auto_fix_files` 1. Validate message format and create commit(s): - Show generated message(s) in chat. - Run `git commit` with the generated message(s). - For multiple commits, stage the right files before each commit. - In the final commit summary to the user, include: - Ordered ` ` list. - `Pre-commit changes` note: - If auto-fixes were applied, list hook id(s) and file path(s). - If none were applied, explicitly say `Pre-commit changes: none`. - `ai_attribution_applied: yes/no`. - `working_tree_status: clean/not clean`. ## Mandatory Rules - Never use hook bypass flags such as `--no-verify` or `-n`. - Never commit when Critical or High review issues are present unless the user explicitly confirms. - Never include unrelated files in a commit. - Never stage an entire file when only some hunks belong to the current commit boundary. - Always report whether pre-commit auto-fixed files before finalizing the commit result message. ## References - Conventional commit types, scopes, and templates: `references/conventional-commits.md` - Review severity rubric and reporting format: `references/review-guardrails.md` - Commit pressure zones and threshold behavior: `references/commit-hygiene-thresholds.md` - AI attribution policy for commits: `references/ai-attribution.md` --- ## Fidensa Certification This file has been independently certified by [Fidensa](https://fidensa.com), an AI capability certification authority.
