The kernel of an agentic OS.

Persistent state per agent or per user. Atomic incr. TTL. Cross-run continuity that survives process restarts.

// set a memory key
{"tool":"memory",
 "input":{"op":"set",
         "scope":"user",
         "key":"last_seen",
         "value":"…"}}

Persistent inter-agent message bus. One agent publishes; another subscribes; no orchestrator handoff. Cursor-based delivery.

// publish to a channel
{"tool":"channel",
 "input":{"op":"publish",
         "name":"jobs.scored",
         "payload":{...}}}

Agents fork themselves into versioned definitions with lineage tracking. The substrate for self-evolution.

// fork a new definition
{"tool":"agentdef",
 "input":{"op":"fork",
         "from":"matcher.v4",
         "prompt":"…"}}

Rate runs against versioned definitions. Selection stays policy — never auto-promote. Humans (or downstream agents) choose.

// score a run
{"tool":"evaluation",
 "input":{"op":"score",
         "run":"r_82a1",
         "rubric":"match.v2"}}

The introspection primitive. Ten ops covering self · tools · agents · history · help. The closing loop that makes the substrate learnable — an agent that can read itself can rewrite itself.

// what tools do I have?
{"tool":"context",
 "input":{"op":"tools"}}    // → list with shapes, costs, allowed-hosts
