  • /planning enables multi-turn plan mode — produce a plan before big engineering tasks; /permissions switches global policy between request-review/always-proceed/strict.
  • /agents and /tasks monitor background subagents and shell execution logs respectively, giving a clear view of each parallel task progress.
