Find the perfect skill

Documentation

Generates specification templates for non-trivial changes using GitHub Spec Kit 4-stage workflow (Specify → Clarify → Tasks → Implement). Creates GitHub issues and spec files automatically.

Testing

Enforces the TDD cycle: write a failing test (red), implement minimal code to pass (green), then refactor while keeping tests green. Best for any testable code change, especially in projects using Vitest.

Development

A test skill for experimenting with the SKILL.md format. It uses the 'name' field instead of the 'id' field in the frontmatter. This skill is useful for verifying that Claude Code correctly parses SKILL.md files.

DevOps

Creates a properly named feature branch from the development branch with remote tracking, following the naming convention 'feature/issue-<number>-<short-description>'. Validates inputs, syncs with remote development, and pushes the new branch with upstream tracking. Best used at the start of a new feature implementation or when picking up a GitHub issue.

DevOps

Prepare a release by verifying success criteria, backwards compatibility, ticket tagging, and documentation. Automates comprehensive validation before deployment.

Data & AI

Predicts stock direction and magnitude at earnings release using point-in-time data only. Implements PIT filtering architecture to prevent data contamination from post-filing market reactions.

DevOps

This skill analyzes a GitHub pull request by fetching its metadata, diff, and comments, then sets up an isolated worktree for code review. It checks dependency changes in pyproject.toml, CI lint status, and related issues, and performs deep code analysis on changed files. Use this when you need a comprehensive, automated PR review with local context and dependency validation.

Development

View details of a pull request including title, description, status, author, and branches. Use this to understand what a PR is about or check its status before review.

Education & Training

Guide discovery through questioning for deep understanding of any topic. Socratic teaching methodology for interactive learning.

Data & AI

Automatically navigates through quiz funnels for competitive intelligence, capturing every screen and generating a comprehensive analysis report covering structure, personalization, paywall tactics, and strengths/weaknesses. Helps in understanding competitors' quiz strategies and identifying psychological and conversion tactics.

DevOps

Configure Dialyzer for static analysis and type checking in Erlang/Elixir. Manage PLTs, analysis flags, and warning filters.

Productivity

Create new Agent Skills for GitHub Copilot from templates. Generates SKILL.md files with proper structure, directory layout, and bundled resources.
