Skill Retrieval Gate

Goal

Use this skill to decide whether the current task should query memory_search before following another skill or workflow.

This skill is for retrieval judgment, not mandatory retrieval.

Core rule

Do not make every skill query memory first.

Instead:

1. Judge whether the task depends on local knowledge or history
2. Retrieve only when that dependency is real
3. Load only a few high-signal results
4. Fall back immediately if retrieval is weak, unavailable, or unnecessary
