Curator Specification
The open protocol behind the Curator agent environment manager, implementable by any conforming manager.
What it is
The Curator Specification defines an open protocol for managing AI agent environments: skill package formats, project manifests, dependency closure resolution, installation layouts, MCP server requirements, and a cryptographically verifiable audit registry.
The protocol is independently implementable. The reference implementation is Curator (Go); an independent Python implementation conforms to the same wire formats, which is the working proof that the document alone is enough to build an interoperable manager. That matters for organizations whose internal security policies require an in-house build instead of adopting an external binary.
Highlights
- Byte-exact contracts: content hashes, install markers, and canonical signing bytes are specified to the byte, gated by golden fixtures.
- Deny-wins audit federation over Ed25519-signed records with rollback and freeze detection.
- Multi-agent delivery with managed adapters, three install scopes, and Windows as a first-class target.
