Visual workflow builder with protocol-level enforcement for AI coding agents. Your AI agent gets the right tools in each phase — nothing more, nothing less. No prompt engineering. No jailbreaks. Structural guarantees.

Tool enforcement per phase. Fewer wasted tokens. Your tools, automatic.

1. Design your workflow — drag states, draw transitions, assign tools per phase.

2. Connect your agent — two commands in Claude Code.

3. Agent follows the process — every transition enforced, every tool call audited.

Per-state tool enforcement. Decision checkpoints. Edit and command guards. Transition audit log.

Free to start. No credit card. 200 transitions/month on the free tier.
