# IAiSdkDocs interface

Namespace: [Grasshopper2.Components.Descriptive](https://developer.rhino3d.com/api/gh2/namespace/grasshopper2.components.descriptive.md) · Assembly: [Grasshopper2](https://developer.rhino3d.com/api/gh2/assembly/grasshopper2.md)

```cs
public interface IAiSdkDocs
```

Lookup service that surfaces Grasshopper2 SDK information to the model during code generation. Implementations are expected to be fast and in-process -- the model calls these tools multiple times per generation and tool latency directly extends the user's wait time.

**Derived types:** [InMemoryAiSdkDocs](https://developer.rhino3d.com/api/gh2/type/grasshopper2.components.descriptive.inmemoryaisdkdocs.md)

## Methods

- [GetExample](https://developer.rhino3d.com/api/gh2/type/grasshopper2.components.descriptive.iaisdkdocs/getexample.md): Return a worked example for a named topic, or null if no example exists for that topic. Used for idiomatic patterns where the answer is "how do I do X in Grasshopper2?" rather than "what does symbol Y look like?".
- [LookupSymbol](https://developer.rhino3d.com/api/gh2/type/grasshopper2.components.descriptive.iaisdkdocs/lookupsymbol.md): Return the top `max` matches for the query, ranked by relevance. Used for "does this symbol exist? what's its signature?" questions. An empty array means no match -- the model should treat that as a signal that it should not use the symbol it was about to.
