The Overview
Project context & goals
A trust runtime for AI agents: it checks every tool call against a policy and keeps tamper-evident evidence of what happened.
Astrail sits between an AI agent and the tools it can call. It authenticates the caller, normalises each requested call into a canonical action validated by JSON Schema, applies a deterministic YAML policy of allow, deny, and require-approval rules, and records the outcome as SHA-256 hash-chained evidence that shows whether any record was changed, deleted, or reordered.
Written in Rust as a Cargo workspace, it is at a v0.1 release candidate, with a fail-closed production mode, at-most-once execution, simulated replay, policy comparison, a keyboard-operable dashboard, and fuzz and security test suites. What is left is three outside developers finishing the quickstart.
