Summary
Define and persist agent identity, memory, and trust signals across tools and sessions. Implements an open protocol for carrying an agent's profile, learning state, and provenance so agents remain identifiable and auditable as they move between systems. Notable features include local-first storage options (SQLite), TypeScript SDK primitives, and hooks for recording operator edits and reputation signals.
Why It Matters
As agents interact and delegate, knowing which agent produced what and how reliable it is becomes essential for safety and orchestration. Signet gives a standard way to record an agent's track record, learning history, and provenance so downstream systems can make informed trust decisions. This matters because A2A trust, evaluation, and continuous agent evaluation pipelines.
Target Use Cases
Teams building multi-agent systems that need a portable agent identity, provenance tracking, and reputation signals across tools.
Real-World Examples
- Persisting an agent's identity and learning state across sessions and toolchains
- Recording provenance and operator edits to build an agent track record for downstream evaluation
- Providing reputation and trust signals to orchestration layers for safer agent delegation
