aeoess/agent-passport-system

Here's a technical summary focused on what the one-line description doesn't cover: **Enforces constraints at execution time via a proxy gateway that intercepts all agent tool calls—evaluating 15 constraint dimensions (scope, spend limits, reputation tier, revocation status, values floor) in sub-2ms latency before the agent ever touches the underlying tool. Generates tamper-proof, hash-chained Ed25519-signed receipts for every action (permit or deny), making enforcement cryptographically auditable. Integrates directly with CrewAI, LangChain, and custom frameworks via governance wrappers that sit between agent and tools.**
