File Watchers

The watcher subsystem monitors directories for file changes and triggers actions automatically.

Configuration

Watcher rules live in ~/.claude-superpowers/watchers.yaml. Each rule specifies a path pattern, event types to watch, and an action to execute.

Rule Format

- name: torrent-mover
  path: ~/Downloads/*.torrent
  events: [created]
  action: move
  command: /mnt/data/torrents/watch/
  enabled: true

Fields

Field Required Description
name yes Unique identifier for the rule
path yes Directory or glob pattern to watch
events no Event types: created, modified, deleted, moved (default: [created])
action yes Action type: shell, skill, workflow, move, copy
command yes Action-specific command or target
args no Extra arguments (dict, passed to action)
enabled no Whether the rule is active (default: true)
