# Knowledge and code

## Find knowledge: `search_knowledge`

Searches a project's notes and documents by their **title**, not their text.

| Argument | Meaning |
|---|---|
| `q` | required, the search term |
| `type` | only `note` or only `document` |
| `page`, `per_page` | page, at most 100 per page |

Each hit carries a ready link of the form `lalabase://note/<uuid>`. How to use it is covered under
[link documentation](https://lalabase.com/docs/en/mcp/workflows/link-documentation). If you may not read one kind, it simply
returns no hits.

## Code context

If a project has a [connected repository](https://lalabase.com/docs/en/guides/repositories/connect), Lalabase knows its
structure. These tools go from large to small:

| Tool | Returns | Arguments |
|---|---|---|
| `get_project_vision` | a summary of what the project is and what it consists of | none |
| `list_capabilities` | the capabilities, coherent feature areas | none |
| `get_capability_details` | one capability with description and key modules | `capability_id` |
| `search_code_symbols` | classes, modules and methods that fit a question | `query`, `limit` (default 10, at most 25) |
| `get_symbol_details` | signature, file, lines and language of a symbol | `qualified_name`, such as `Chatpost#destroy` |

These tools return no source code: `get_symbol_details` names the place, not its content. If the
code is on your machine, the agent reads it there.

## Prerequisites

The code tools answer only for projects whose repository you may see yourself. The token alone
is not enough, and without that right the project counts as not found here. If no code has been
read in yet, the answer says so.

The five code tools also need [your organisation's AI](https://lalabase.com/docs/en/guides/ai/enable-disable): a repository
is read in only with AI switched on. Without it, they keep answering that nothing has been read in
yet. `search_code_symbols` also uses the AI on every search and is refused if it has been switched
off since or a key is missing. `search_knowledge` works without AI.

All tools on this page need a `project_id`.
