Struct SkillWatcher 

pub struct SkillWatcher { /* private fields */ }

Background watcher for a skill directory.

Uses the OS-native FS notification API (kqueue on macOS, inotify on Linux). Callers snapshot version() at the start of each SM iteration and re-scan the directory whenever the value has changed — no polling thread needed.

Implementations

impl SkillWatcher

pub fn start(dir: &Path) -> Option<Self>

Start watching dir. Returns None if the path doesn’t exist or the OS watcher cannot be created (e.g. unavailable on this platform).

pub fn version(&self) -> u64

Monotonically-increasing counter; increments whenever a .md, .json, or .py file in the watched directory is created, modified, or removed.

Callers should snapshot this at the start of each loop iteration and compare against the previous snapshot; a change means the skill catalog should be refreshed.
