Top PI-EXTENSION GitHub Repositories & Tools (2026)

Asynchronous Pi subagents and agent fleet orchestration for parallel coding agents with nested delegation, background work, and supervision in herdr.

A pre-execution guard for AI coding agents. It blocks destructive Git and file system commands, plus common attempts to access sensitive files, before a tool call runs. Supports Amp Code, Antigravity CLI, Claude Code, Codex, Cursor, Gemini CLI, GitHub Copilot CLI, Grok Build, Hermes Agent, Kimi Code, OpenClaw, OpenCode, and Pi.

Guardrails for Pi that steer instead of interrupt: enforces your project rules on every write, holds only hard-to-undo actions (3 per 1,000 calls, measured on real sessions), catches unverified "done" claims and stuck loops, and trims tool output. Built on pi-typesafe.

Semantic tool routing and typed System One decisions for the Pi coding agent using TypeSafe Jev

Run the pi coding agent as a service — triggered on demand, on a cron schedule, or by a GitHub or GitLab issue, comment or pull/merge request — in a container you control, with a durable queue, a spend cap, and a live admin panel.
