# hasSkillByKey

> Check if a skill with the given instance key is loaded.

Direct map lookup by instance key (matches Python's `has_skill(skill_identifier)`
semantics). Use `hasSkill(name)` to search by skill name instead.

## **Parameters**

**`instanceKey`** `string` — required

The instance key to look up (e.g., `"weather"` for single-instance skills, or
`"weather_forecast"` for a multi-instance skill keyed by `tool_name`).

## **Returns**

`boolean`

> Check if a skill with the given instance key is loaded.
