Scan:
who/coordination/for cross-agent communication — urgency levels (urgent/info/fyi), ephemeral notes, required contents.
Decisions: D9
11.1 Cross-Agent Coordination
Cross-agent notes live in who/coordination/. This is the single location for agent-to-agent communication.
Coordination notes are ephemeral by design: created when needed, consumed by the target agent, and archived when resolved.
11.2 Urgency Levels
| Level | Meaning | When to Read |
|---|---|---|
urgent | Immediate action needed | Read before any other work |
info | Important context | Read during startup checklist |
fyi | Non-blocking background information | Read when convenient |
11.3 Coordination Note Contents
A coordination note MUST include:
- Who created it and who it targets
- What the coordination concern is
- When it was created and when it expires
- Action needed — what the target agent should do
Agents MUST check who/coordination/ during every session startup.
