MCP App StoreMCP App StorePI (π) is a comprehensive problem-solving skill that provides a rigorous workflow for debugging, code review, product decisions and team coordination. It codifies a search→read→verify→deliver pipeline, stepwise debugging protocols, failure escalation (multi-stage), and evidence requirements for fixes and audits.
Use PI when tackling reproducible bugs, performing strict code reviews, coordinating multi-step deliveries, or when failures have occurred repeatedly and require escalation. It is designed for engineering and product teams demanding traceable, verifiable fixes.
Best used with agents that can run commands and attach outputs for verification (Claude Code, Copilot-style assistants, local exec-capable agents).

Development Worktree
Create an isolated git worktree for feature work, auto-run project setup, and verify a clean test baseline before development.
ds-fix — data-science mid-analysis fixer
Orchestrates diagnosis and targeted fixes mid-analysis: diagnose root cause, apply fixes with output-first verification, and update project learnings.
Full Stack Builder
End-to-end builder that scaffolds, implements, tests, and optionally deploys web and API applications from a natural-language specification.
Claw Bench
Benchmarking skill that guides an agent through a structured suite of capability tests and reporting steps for leaderboard submission.
Tmux Bridge
Give an agent controlled access to a local tmux terminal bridge so it can run shell commands, capture output, and manage sessions on the user's machine.
