Minimal terminal coding harness

Pi is an open-source minimalist coding agent built by Mario Zechner that runs in the terminal with an intentionally lean design — just four core tools (read, write, edit, bash) and a ~300-word system prompt. It treats the context window as scarce, omits sub-agents and MCP by default, and pushes extensibility to TypeScript extensions, skills, and prompt templates developers build for their own needs. A radical counterpoint to bloated AI coding tools.

AI coding agent with hash-anchored edits, LSP, subagents, and browser tools

AI-powered code migration tool that automates framework upgrades, language migrations, and API version transitions. Analyzes your codebase to generate migration plans, then applies changes systematically across affected files. Reduces the risk and effort of major upgrades by handling the tedious, error-prone aspects of codebase-wide transformations that would take developers weeks to complete manually.

Multi-agent CLI pair programmer with FORGE, MUSE, and SAGE agents
