# search_knowledge

> Search the knowledge base for framework docs, APIs, and best practices

Search the knowledge base for framework documentation, API references, config formats, and best practices. An AI agent synthesizes a grounded answer with `[PageID]` citations.

## When to Use

* **Before coding:** Understand how a framework or library works before implementing
* **Looking up config formats:** Data structures, expected behavior, API contracts
* **Architecture questions:** Design patterns, conventions, internal workings
* **Verified information:** Get documented facts instead of guessing

<Tip>
  Call this tool **multiple times in parallel** with different queries to search from multiple angles at once. This is much faster than sequential searches.

## Parameters

| Parameter | Required | Type   | Description                                 |
| --------- | -------- | ------ | ------------------------------------------- |
| `query`   | Yes      | string | What you want to find out                   |
| `context` | No       | string | Optional context about what you're building |

## Example

```
Tool: search_knowledge
Query: "How does device_mapping work in ROLL?"
Context: "I am implementing a distributed RL training setup"
```

**Returns:** A synthesized answer with `[PageID]` citations that can be followed up with [`get_page`](/docs/tools/get-page).
