hive-agent-sock

What's common across the in-container "agent plugins" — the matrix / bash / subagent MCP daemons and forge_notify today, plus any user-configured MCP server declared in an agent's agent.nix. Two things live here:

Wire types for the in-agent socket

The socket the hive-agent harness serves inside the container to those local producers. Any producer can dial it and push its own todos with an arbitrary subsystem marker — the wire format doesn't restrict the set. Unlike the host-served sockets, this one never leaves the container.

  • the loose-ends-v2 todo op family
  • the harness-local reminder op family

More in-agent request families may be added over time — the socket is deliberately named for the agent, not for the todos.

Why in-container: the harness owns the todo + reminder stores locally and signals its own turn loop directly, so hive-c0re is not in either path: no broker round-trip, no long-poll, no marker files. That locality is the point — it's also what lets these stores travel with the agent for hive portability.

Not to be confused with hive-core-agent-sock: that crate is the host-served core↔agent protocol on /run/hive/mcp.sock (the harness talking out to hive-c0re). This socket is purely intra-container.

extra_mcp: the hyperhive.extraMcpServers spec

Not a socket protocol — a shared config type. Parses /etc/hyperhive/extra-mcp.json (the nix-rendered hyperhive.extraMcpServers option) and renders each entry into the shape claude expects in a --mcp-config blob. Shared by hive-agent (the main session's servers) and hive-subagent-mcp (the subagent-eligible subset, gated on availableToSubagents) — both already depend on this crate for the socket types above, so a new plugin-facing shared type belongs here rather than in a crate of its own.
