start-right
by slamb2k
Comprehensive repository initialization and scaffolding for new projects. Use when setting up a new repository from scratch with git, GitHub, CI/CD workflows, branch protection, validation checks (format, lint, type-check, tests, builds), git hooks (husky/lefthook), GitHub Actions for PR and main branch validation, automated versioning and tagging, and project-specific release workflows. Ideal for solo developers who want production-ready repository setup including (1) Git initialization with main branch, (2) GitHub repository creation and configuration, (3) Branch protection rules, (4) PR workflow with squash merging and auto-delete branches, (5) Comprehensive validation checks, (6) Git hooks for pre-commit and pre-push validation, (7) GitHub Actions CI/CD pipelines, (8) Automated releases with GitHub Releases integration.
play-tight
by slamb2k
Context-efficient browser automation using Playwright scripts and subagent isolation. Use when you need to interact with web pages, extract data from websites, verify page elements, or automate browser tasks while avoiding context window pollution from verbose HTML/accessibility trees. Provides both direct script execution and a specialized subagent pattern for complex investigations that generate large intermediate responses.
refactor

by Krosebrook
Analyzes CSV files, generates summary stats, and plots quick visualizations using Python and pandas.
test-driven-development
by Krosebrook
Use when implementing any feature or bugfix, before writing implementation code - write the test first, watch it fail, write minimal code to pass; ensures tests actually verify behavior by requiring failure first
git-pushing
by Krosebrook
Stage, commit, and push git changes with conventional commit messages. Use when user wants to commit and push changes, mentions pushing to remote, or asks to save and push their work. Also activates when user says "push changes", "commit and push", or similar git workflow requests.
