action-gate

Deterministic preflight check for a proposed AI agent action - a tool call, payment, fetch, or write - before it executes.

Deterministic preflight check for a proposed AI agent action - a tool call, payment, fetch, or write - before it executes. Evaluates up to four independent checks (prompt-injection scan on action text/untrusted text, URL/hostname validation, a bounded JSON-schema check on a payload, and a spend proposal against a spend mandate) and returns ALLOW, REVIEW, or BLOCK with stable reason codes plus a SHA-256 request/receipt hash pair.
