IN THE FIELD GUIDE
Act101
act101.ai
act101 is quality infrastructure software designed for AI-written code, providing deterministic refactoring, porting across 163 grammars, and a merge gate that ensures consistent merge decisions with signed receipts and rollback capability. It offers a native binary with MCP and CLI interfaces, supporting agentic refactoring and cross-language porting workflows.
THE PRODUCT, BEYOND THE PITCH
Editorially reviewed · Sources checked Sep 30, 2026
A good fit for
- Open-source maintainers running agents on open-source repositories with free access to core features.
Know the limitations
- Not intended for solo autocomplete users who only complete occasional lines.
What you can do
- Individual engineers verifying every refactor their AI agent makes before merging.
- Codebase owners or architects monitoring structural drift and proving refactors on every commit.
Features
- Deterministic refactoring operations with 182 AST-aware refactor operations.
- Cross-language porting operations with 10 porting operations supporting source-to-target contract, inventory, ordering, and manifest workflows.
- Merge gate (act gate) that attests changes with deterministic MERGE / REVIEW / BLOCK verdicts, signed receipts, and one-command rollback.
- 42 codebase analyzers for deep analysis including dead code, cycles, coupling, hotspots, and seams.
- 18 query operations for core AST queries like skeleton, symbols, graph, references, and definitions.

A practical workflow
- Install one native Rust binary with no dependencies or supply chain risk.
- Connect your agent with one command to supported agents like Claude Code, Cursor, Codex, Windsurf, Zed, or opencode.
- Gate every change where the agent analyzes and acts, and act gate attests with a verdict and receipt.
