The Pi project

Cheasee-Pi stands on the shoulders of the Pi coding agent — the extensible AI coding harness that makes all of this possible. Pi’s extension API, prompt template system, and modular architecture are the foundation of this project.

Runtime & tools

• scrapling — Memory-optimized web scraper with progressive fetching
• rtk — Token-saving CLI proxy that rewrites agent shell commands for 60-90% less output
• GitHub CLI (gh) — GitHub API client powering issues, PRs, and releases
• Zed — The editor

Communication & workflow

• Caveman — Origin of the caveman communication style (“why use many token when few word do trick”). Cheasee-Pi ships an in-house multi-level caveman mode extension built on the same idea.
• Ponytail — Origin of the lazy senior dev mode (YAGNI, stdlib-first, minimal code). Installed as a package and extended with in-house audit, review, and debt skills.

The cheasee-pi CLI

• Go — Build language for the cheasee-pi binary
• Charmbracelet huh — Terminal UI forms for interactive prompts
• cobra — CLI framework
• go-git — Git repository operations
• cli/oauth — Device-flow OAuth for GitHub authentication

Security & pipeline

• osv-scanner — Vulnerability scanning across lockfiles in the audit pipeline
• @octokit — GitHub API client used by the supervisor pipeline

Open source tools

• ast-grep — Structural code search engine via Tree-sitter AST
• ripgrep — Ultra-fast literal/regex code search
• Jekyll — Static site generator
• Just the Docs — Documentation theme
• Docker — Container runtime
• Node.js — JavaScript runtime
• TypeScript — Type system and compiler
• Pi SDK & Extensions Documentation — Extension API, commands, hooks, theme system
