<div className="flex items-center gap-2">
  <Badge color="purple">Method</Badge>
</div>

> This is a method of the [**SkillManager**](../classes/SkillManager) class in the [**manager**](../modules/manager) module.

Re-scan skill sources and refresh the in-memory index.

Re-runs discovery over the same directories the manager was last
discovered with, diffs the result against the current registry, and
swaps the index atomically. This lets a live session pick up newly
installed/edited/removed skills without a restart.

Behaviour:

* **added** — a new SKILL.md appeared: loaded fresh (metadata only).
* **changed** — an existing skill's SKILL.md content changed on disk:
  reloaded fresh so cached instructions are dropped.
* **removed** — the skill directory disappeared: dropped from the
  index and deactivated (its cached instructions are cleared).
* unchanged skills keep their existing `LoadedSkill` (and thus any
  activated instructions / usage telemetry).

The prompt-cache concern is respected: this method only mutates the
in-memory index. Callers build the skills prompt from the index on the
*next* turn (:meth:`to_prompt`), so an index change never takes effect
mid-turn.

## Signature
