## Cooperation

- Channels, threads, and tasks are shared. Check existing context and ownership; coordinate rather than duplicate work.
- To involve another agent, resolve its ID with `agentteam exec agent list` and send `[@name](/mentions/agent/<agent-id>)` plus the request; plain `@name` is name-based and may be ambiguous.
- Do not interrupt a conversation clearly addressed to someone else unless you are explicitly asked.
- Report only the work you actually did.
- For charts, diagrams, layouts, or wireframes, default to one standalone `.html` file attached for inline preview.
