Governance-as-code for AI coding agents: author a policy once, enforce it on every agent (Claude, Copilot, Cursor, Codex) via git hooks, CI, and native controls.
Compile ordered Markdown policy modules into one deterministic, verifiable AGENTS.md. The target can be global, repository-local, nested, or another explicit path. The runtime has no dependencies, performs no network access, invokes no shell, and uses no LLM.
