Cross Agent Context

Cross-Agent Context Protocol (CACP)

CACP provides shared memory namespaces for multi-agent collaboration. Sessions can link together to share context, detect conflicts, and resolve diverging state.

Architecture

The protocol lives in src/memory/cross-agent-context.ts and provides:

• Shared Context — namespace-keyed values with version vectors
• Conflict Detection — when two sessions write different values to the same key, a conflict is flagged
• Conflict Resolution — accept one session's version
• Session Linking — group sessions under a shared namespace
