Summary

From pi-mono subagent example + our current subagent flows, there are a handful of small, low-risk improvements that would improve reliability and UX.

Ideas

• Persist subagent run registry so announce survives gateway restarts (currently in-memory only).
• Add stats parity in announce: turns + cache read/write + ctx tokens.
• Include last N tool call previews in announce (short/truncated) for quick debug.
• Add project-agent gating + source metadata in announce (user vs project).
• Cache agent discovery per-repo with short TTL to avoid repeated IO.
• Expose per-agent maxConcurrent + queue length; fail fast with clear error.
• On timeout: auto-archive/delete to avoid orphan sessions.
• Enforce structured announce output (Status/Result/Notes) for parseability.
• Surface stopReason + stderr snippet when failed.
• Per-agent tool allow/deny list in config (least privilege).
