  • Agent session: Run fetchMcpToolMetadata, getModelConfigOptions and getAvailableSlashCommands in parallel. Make trySetModel fire-and-forget. Same pattern for resumeSession
  • Workspace setup: Parallelize loadConfig + buildWorkspaceEnv in local mode (worktree mode already did this)
  • Reconnect: Batch config option restoration with Promise.allSettled instead of sequential awaits
  • Task creation saga: Start folder registration in parallel with task creation for new tasks
