+
+# Commit Message Storyteller
+
+Transforms raw git diffs and change descriptions into clear, story-driven commit messages that follow the [Conventional Commits](https://www.conventionalcommits.org/) specification. Instead of "update file.js", you get messages that communicate intent, context, and impact.
+
+## When to Use This Skill
+
+- User says "write a commit message", "help me commit", or "generate a commit"
+- User pastes a git diff or describes code changes
+- User says "what should I commit this as?" or "summarize my diff"
+- User wants better commit history for their team or open-source project
+- User is preparing a pull request and wants meaningful commit messages
+
+## Prerequisites
+
+Have at least one of the following ready:
+- Output from `git diff` or `git diff --staged`
+- A description of what you changed and why
+- A list of modified files
+
+## How It Works
+
+### Step 1: Gather the Change Context
+
+Ask the user (or infer from the diff) for:
+
+1. **What changed** — files, functions, logic affected
+2. **Why it changed** — bug fix, new feature, refactor, performance, etc.
+3. **Who/what triggered it** — issue number, user request, tech debt, etc.
+
+If the user provides a raw `git diff`, extract this context automatically from the diff.
+
+### Step 2: Identify the Commit Type
+
+Map the change to a Conventional Commits type using this guide:
+
+| Type | Use When |
+|------|----------|
+| `feat` | A new feature or capability is added |
+| `fix` | A bug or incorrect behavior is corrected |
+| `refactor` | Code restructured without changing behavior |
+| `perf` | A change that improves performance |
+| `docs` | Documentation only changes |
+| `style` | Formatting, whitespace, missing semicolons (no logic change) |
+| `test` | Adding or updating tests |
+| `chore` | Build process, dependency updates, config changes |
+| `ci` | CI/CD pipeline changes |
+| `revert` | Reverting a previous commit |
+
+See `references/conventional-commits-guide.md` for detailed examples.
+
+### Step 3: Write the Commit Message
+
+Follow this structure:
+
+```
+<type>(<optional scope>): <short imperative summary>
+
+<body — the story: why this change was made, what problem it solves>
+
+<footer — issue refs, breaking change notices>
+```
+
+#### Rules for Each Part
+
+**Subject line (first line):**
+- Use imperative mood: "add", "fix", "remove" — not "added" or "fixes"
+- Max 72 characters
+- No period at the end
+- Lowercase after the colon
+
+**Body (the story):**
+- Explain the *why*, not the *what* (the diff already shows the what)
+- Describe the problem that existed before this change
+- Mention any alternatives considered if relevant
+- Keep lines under 100 characters
+- Separate from subject with a blank line
+
+**Footer:**
+- Reference issues: `Closes #123`, `Fixes #456`, `Refs #789`
+- Mark breaking changes: `BREAKING CHANGE: <description>`
+
+### Step 4: Generate Output
+
+Produce the commit message in a copyable code block, followed by a one-line plain-English explanation of the story you told.
+
+**Example output:**
+
+```
+fix(auth): prevent token refresh loop on expired sessions
+
+When a user's session expired mid-request, the auth middleware was
+triggering a token refresh, which itself failed validation and triggered
+another refresh — causing an infinite retry loop that crashed the app.
+
+This adds a recursion guard flag that aborts the refresh cycle if a
+refresh is already in progress, returning a clean 401 instead.
+
+Closes #312
+```
+
+> **Story told:** A silent infinite loop on session expiry was crashing the app; this stops the cycle early and returns a clean error.
+
+---
+
+## Multiple Commits from One Diff
+
+If the diff contains **logically separate changes**, split them into multiple commit messages and tell the user. Use this heuristic:
+
+- Different files with unrelated purposes → likely separate commits
+- Same file but distinct concerns (e.g., bug fix + refactor) → suggest splitting
+- Everything tightly coupled → one commit is fine
+
+---
+
+## Edge Cases
+
+| Situation | How to Handle |
+|-----------|---------------|
+| User provides no context beyond a diff | Infer type and scope from file names and changed symbols |
+| Changes span many files with no clear theme | Ask: "Is this one logical change, or multiple?" |
+| Breaking change detected | Add `BREAKING CHANGE:` footer automatically |
+| User says "keep it short" | Omit body, just write a strong subject line |
+| No issue number available | Omit the footer entirely |
+
+---
+
+## Quick Reference
+
+```bash
+# Get your staged diff to paste into Copilot
+git diff --staged
+
+# Or get the last uncommitted working tree changes
+git diff
+```
+
+See `references/conventional-commits-guide.md` for type examples and scope guidelines.

+# Conventional Commits — Quick Reference Guide
+
+Full spec: https://www.conventionalcommits.org/en/v1.0.0/
+
+---
+
+## Format
+
+```
+<type>(<scope>): <description>
+
+[optional body]
+
+[optional footer(s)]
+```
+
+---
+
+## Type Examples
+
+### `feat` — New Feature
+```
+feat(payments): add Apple Pay support for checkout flow
+
+Users in supported regions can now complete purchases using Apple Pay.
+This reduces checkout friction and is expected to improve mobile conversion rates.
+
+Closes #88
+```
+
+### `fix` — Bug Fix
+```
+fix(api): correct off-by-one error in pagination offset
+
+The results page was skipping the last item on every page because the
+offset calculation used `>` instead of `>=`. Users were missing records
+silently with no error.
+
+Fixes #201
+```
+
+### `refactor` — Code Restructure (no behavior change)
+```
+refactor(user-service): extract email validation into shared utility
+
+Email validation logic was duplicated across 4 modules. Extracted into
+`utils/validators.ts` so future changes only need to happen in one place.
+```
+
+### `perf` — Performance Improvement
+```
+perf(dashboard): lazy-load chart components to reduce initial bundle size
+
+The dashboard was importing all chart types upfront, adding ~180KB to the
+initial load. Charts are now loaded on demand, cutting initial load time
+by ~40% on slow connections.
+```
+
+### `docs` — Documentation Only
+```
+docs(readme): add local development setup instructions
+
+New contributors were struggling to get the dev environment running.
+Added step-by-step instructions covering Node version, env vars, and
+the database seed command.
+```
+
+### `test` — Tests Added or Updated
+```
+test(auth): add coverage for concurrent login edge cases
+
+The login flow had no tests for simultaneous requests from the same
+session. Added tests that verify only one session token is issued
+when multiple requests arrive in the same tick.
+```
+
+### `chore` — Maintenance / Config
+```
+chore(deps): upgrade eslint from v8 to v9
+
+v8 reached end-of-life. Migrated config to flat config format required
+by v9. No rule changes — this is a tooling-only update.
+```
+
+### `ci` — CI/CD Pipeline
+```
+ci: add caching for node_modules in GitHub Actions
+
+Cold CI runs were taking 4+ minutes due to repeated installs.
+Adding cache restore on lockfile hash reduces this to ~90 seconds.
+```
+
+### `revert` — Reverting a Commit
+```
+revert: feat(notifications): add push notification opt-in
+
+Reverts commit a3f92bc.
+
+The push notification feature caused a crash on Android 12 devices.
+Rolling back until the root cause is identified.
+```
+
+---
+
+## Scope Guidelines
+
+The `scope` is optional but strongly recommended. It should be:
+- A short noun identifying the area of the codebase: `auth`, `api`, `dashboard`, `payments`
+- Consistent across the project (don't mix `user` and `users`)
+- Omitted if the change is truly global
+
+---
+
+## Breaking Changes
+
+Add `BREAKING CHANGE:` in the footer (or use `!` after the type):
+
+```
+feat(api)!: remove v1 endpoints
+
+All v1 REST endpoints have been removed following the 6-month deprecation
+notice. Consumers must migrate to v2 before upgrading.
+
+BREAKING CHANGE: /api/v1/* routes no longer exist. See migration guide at docs/v2-migration.md
+```
+
+---
+
+## Body Writing Tips
+
+Ask yourself before writing the body:
+- **What was broken / missing before this change?**
+- **Why was this approach chosen over alternatives?**
+- **What will be different for users or developers after this?**
+
+Avoid:
+- Restating what the diff already shows ("changed the variable name")
+- Vague language ("various improvements", "miscellaneous fixes")
+- Future tense ("this will fix...") — write in present/past tense
+

+
+## Commit Message Anti-Patterns
+
+| ❌ Bad | ✅ Better |
+|--------|----------|
+| `fix bug` | `fix(cart): prevent duplicate items on rapid add-to-cart clicks` |
+| `updates` | `feat(profile): allow users to update display name` |
+| `WIP` | Don't commit WIP — stash it |
+| `misc changes` | Split into separate, meaningful commits |
+| `John's changes` | Describe what changed, not who changed it |
