Show HN: Gate – deterministic write-path checkpoint for AI agents

The write-path control plane for AI agents.

AI agents can read systems freely. The problem is writes — CRM imports, email sends, database updates, refunds. Once the agent does it, you can't unsee it.

Gate sits between the agent and production. Agents submit an intent, Gate evaluates a YAML policy, and only then issues a signed execution order. No LLM at evaluation time — same input always produces the same output.

The flow: POST /v1/intents → policy evaluated → approved/blocked/pending POST /v1/intents/:id/execute → gex_ token (15 min TTL) Worker uses token → reports outcome Full audit trail: proposed → policy_checked → approved → execution_requested → execution_succeeded
