Git Commit Helper
Quick start
Analyse staged changes and generate a commit message:
git diff --staged
Commit message format
Follow conventional commits format:
<type>(<scope>): <description>
[optional body]
[optional footer]
Types
- feat: New feature
- fix: Bug fix
- docs: Documentation changes
- style: Code style changes (formatting, missing semicolons)
- refactor: Code refactoring
- test: Adding or updating tests
- chore: Maintenance tasks
Example
feat(auth): add JWT authentication
Implement JWT-based authentication system with:
- Login endpoint with token generation
- Token validation middleware
- Refresh token support
For more examples (bugfix, refactor, multi-file, breaking changes, scopes), see
references/examples.md.
Commit message guidelines
DO:
- Use imperative mood ("add feature" not "added feature")
- Keep first line under 50 characters
- Capitalise first letter
- No period at end of summary
- Explain WHY not just WHAT in body
DON'T:
- Use vague messages like "update" or "fix stuff"
- Include technical implementation details in summary
- Write paragraphs in summary line
- Use past tense
Template workflow
- Review changes:
git diff --staged - Identify type: Is it feat, fix, refactor, etc.?
- Determine scope: What part of the codebase?
- Write summary: Brief, imperative description
- Add body: Explain why and what impact
- Note breaking changes: If applicable
For git commands (analysing diffs, interactive staging, amending commits), see
references/git-commands.md.
Best practices
- Atomic commits - One logical change per commit
- Test before commit - Ensure code works
- Reference issues - Include issue numbers if applicable
- Keep it focused - Don't mix unrelated changes
- Write for humans - Future you will read this
Commit message checklist
- Type is appropriate (feat/fix/docs/etc.)
- Scope is specific and clear
- Summary is under 50 characters
- Summary uses imperative mood
- Body explains WHY not just WHAT
- Breaking changes are clearly marked
- Related issue numbers are included

Expand your agent's capabilities with these related and highly-rated skills.
tampermonkey
Write Tampermonkey userscripts for browser automation, page modification, and web enhancement. Use when creating browser scripts, writing greasemonkey scripts, automating user interactions, injecting CSS or JavaScript into web pages, modifying website behaviour, building browser extensions, hiding unwanted page elements, adding form auto-fill, scraping website data, intercepting requests, detecting URL changes in SPAs, or storing persistent user preferences. Covers userscript headers (@match, @grant, @require), synchronous and async GM_* API functions, common patterns (DOM mutation, URL change detection, element waiting), security sandboxing, and cross-browser compatibility (Chrome, Firefox, Edge).
google-analytics
Comprehensive Google Analytics 4 guide covering property setup, events, custom events, recommended events, custom dimensions, user tracking, audiences, reporting, BigQuery integration, gtag.js implementation, GTM integration, Measurement Protocol, DebugView, privacy compliance, and data management. Use when working with GA4 implementation, tracking, analysis, or any GA4-related tasks.
pdf-processing-pro
Production-ready PDF processing with forms, tables, OCR, validation, and batch operations. Use when working with complex PDF workflows in production environments, processing large volumes of PDFs, or requiring robust error handling and validation. Do NOT use for simple text extraction - use pdf-extract for quick reads.
docx
Comprehensive document creation, editing, and analysis with support for tracked changes, comments, formatting preservation, and text extraction. Use when working with professional documents (.docx files) for creating new documents, modifying or editing content, working with tracked changes, adding comments, or any other document tasks. Do NOT use for creating proposals, letters, or client-facing business documents from scratch - use document-builder for those.
xlsx
Comprehensive spreadsheet creation, editing, and analysis with support for formulas, formatting, data analysis, and visualisation. Use when working with spreadsheets (.xlsx, .xlsm, .csv, .tsv) for creating new spreadsheets with formulas and formatting, reading or analysing data, modifying existing spreadsheets while preserving formulas, data analysis and visualisation, or recalculating formulas.
prp-generator
Generate comprehensive Product Requirement Plans (PRPs) for feature implementation with thorough codebase analysis and external research. Use when the user requests a PRP, PRD, or detailed implementation plan for a new feature. Conducts systematic research, identifies patterns, and creates executable validation gates for one-pass implementation success. Do NOT use for client discovery, requirements gathering, or scope definition - use scope-clarifier for those.
