description=An LLM editing your code is a guess. act101 makes it a transform: your agent refactors or ports the code, then act gate returns a deterministic MERGE / REVIEW / BLOCK verdict with a signed receipt and one-command rollback. 163 grammars, 183 AST refactor operations, 41 codebase analyzers, exposed via MCP (Claude Code, Cursor, Codex, OpenCode) and the act CLI — one native binary. Agent refactor Python. Agent port C to Rust. Agent port Ruby to Elixir.;
