Docfork indexes libraries using a `owner/repo` identifier format. Using these identifiers in your prompts helps the Agent skip the "discovery" phase and query the exact documentation index immediately.
## Syntax
The identifier follows the GitHub-style format:
```text
owner/repo
```
## Usage in Prompts
When you know the library you are using, append the identifier to your prompt.
**Standard Prompt:**
<Conversation>
<Message role="user">How do I use auth?</Message>
<Message role="agent">
<Action>calling `docfork_search_docs` with query: `auth`</Action>
Results may include Auth0, Clerk, NextAuth, or other authentication libraries.
</Message>
</Conversation>
**Targeted Prompt:**
<Conversation>
<Message role="user">Implement auth using `better-auth/better-auth`.</Message>
<Message role="agent">
<Action>
calling `docfork_search_docs` with query: `auth` and docforkIdentifier:
<br />
`better-auth/better-auth`
</Action>
Results are focused exclusively on the Better Auth library.
</Message>
</Conversation>
## Finding Identifiers
You can find the identifier for any supported library in two ways:
1. **Search Results:** When you run `docfork_search_docs`, the JSON response includes a `library_identifier` field for every result.
2. **The Catalog:** Browse our [Library Catalog](https://docfork.com/search) to find the exact ID for your dependencies.
