FAQPage SchemaHow to install Archon?โผ
Run `npx skills add frenzymath/Archon --all -g -y` in your terminal to install all skills in this suite globally.
What does Archon do?โผ
Archon autonomously formalizes research-level mathematics in Lean 4, using a plan agent for strategy and prover agents that write and verify proofs across multi-file projects.
Does Archon work with Claude Code and Codex?โผ
Yes. Archon runs on Claude Code by default and supports Codex since v0.3.0, with other models available through Anthropic-compatible APIs or OpenRouter.
Can Archon handle large Lean projects?โผ
Yes. It is designed for project-level formalization with interdependent theorems, blueprint dependency graphs, multi-lane proving, and a monitoring dashboard.
Is Archon safe to run autonomously?โผ
Use `archon loop --safe` to sandbox file writes to the active project; the default mode grants broad permissions, so a dedicated user or container is recommended.
