# SkillParameter

> Provides access to skill parameter values.

`SkillParameter` represents a single skill parameter — its name, type, value, and whether it can be modified.

## Properties

| Name | Type | Access level | Description |
| :- | :- | :- | :- |
| **IsReadOnly** | bool | Read-write | `true` if the parameter is read-only. |
| **Name** | string | Read-only | The name of the skill parameter. |
| **Type** | [SkillParameterType](/vantage/documentation/skill-designer/document/rule-verification/skill-parameter-type) | Read-only | The type of the skill parameter. |
| **Value** | string | Read-write | The value of the skill parameter. |

<Warning>
  Writing to a parameter whose `IsReadOnly` is `true` interrupts rule execution with an error.
</Warning>
