- * Resolves the set of callable agent names at execute-time by merging the

- * directories appear here alongside built-ins.
+ * Resolves the set of callable agent names for call_omo_agent.
  *
- * Results are cached per session for 30s to avoid redundant SDK IPC calls.
- *
- * Falls back to `ALLOWED_AGENTS` alone if the dynamic lookup fails.
- *
- * @param client - The plugin client with access to the agent registry
- * @param sessionId - Optional session ID for cache scoping
- * @returns Array of lowercase callable agent names (excludes primary-mode agents)
+ * This tool is deliberately narrower than delegate-task: it may only launch
+ * the research lookup agents used by worker-style agents while they continue
+ * local work. Dynamic agents and other built-ins must go through task().
