What

Follow-up to #195, for Greptile's open thread there. messaging-agents-on-the-relay told a session to use the agent-relay-sessions tools whenever it had them. That server is hosted: until its tools are linked to this session, it sends as the agent name approved when it was connected, which can be another agent or another workspace.

The skill (0.2.1) now uses those tools only when they act as this session:

• a session note or [reply: …] line gives a join_relay desktop_address=… call: make it once, then use the tools;
• or they are already linked: this session made that call, or a [reply: …] line names the tools with no join_relay.

Otherwise the session stays on the socket route. That route and the socket-request fallback are unchanged, and so is the rule that a same-named tool from any other server never counts.

The "already linked" signal comes from the core. In crates/probe/src/relay/hosted_mcp.rs (relay), reply hints carry the join_relay text for a session that may not have linked the tools yet, and leave it out once it has.

Versions: skill 0.2.1, agent-relay-setup collection 1.2.2.

Verified

This is a wording change to the skill, checked against the core's source. It was not run end to end through the MCP route, and no message was sent from a real identity.

Follow-up

AgentWorkforce/relay#2032 pins RELAY_SKILL_REF to #195's merge commit. Once this merges, the pin moves to this PR's merge commit before #2032 merges.

[Medium impact] The PR appears safe to merge; no actionable issues were found.

Summary

Restricts agent-relay-sessions tools to cases where the session has evidence that they use its identity.

• The messaging skill uses hosted tools only when they are linked to this session.

Acknowledged intent: kjgbot explicitly states that sessions without linking evidence must stay on the socket route.
