Daemon Configuration (daemon.json) / Claude Code v2.1.119

What

A new JSON configuration file at ~/.claude/daemon.json that defines persistent background workers.

Usage

{
  "scheduled": [{
    "tasks": [{
      "id": "my-task",
      "cron": "*/30 * * * *",
      "prompt": "Check for new issues",
      "directory": "/path/to/project",
      "permissionMode": "dontAsk"
    }],
    "maxConcurrent": 1
  }],
  "remoteControl": [{
    "dir": "/path/to/project",
    "spawnMode": "worktree",
    "capacity": 32
  }]
}

Details

Worker kinds: scheduled (cron tasks), remoteControl (bridge to claude.ai), heartbeat (health monitoring)
Configuration changes are hot-reloaded — the daemon diffs old vs new config and starts/stops/restarts only changed workers
Unknown config keys are reported but don't block startup
Interactive management via the /daemon slash command with tabbed UI for Scheduled Tasks, Remote Control, and Assistants
Each tab supports add, edit, remove, enable/disable operations with inline forms

Evidence

Daemon configuration system (search for "daemon.json", "config validation failed", "config reload failed")

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
