## Summary [#summary]

The **Company Knowledge Agent** answers questions over your internal documents —
issues, wiki pages, notes. It indexes them into a vector store, searches the
corpus first, and redacts personal data (emails, phone numbers, SSNs, card
numbers, API keys) from responses. Reach for it to build an internal "ask the
company" assistant.

      <Step>
        Copy and paste the following agent route files into your project.
      </Step>

      <ComponentSource src="registry/langgraph/company-knowledge/index.ts" title="index.ts" />

      <ComponentSource src="registry/langgraph/company-knowledge/instructions.md" title="instructions.md" />

      <ComponentSource src="registry/langgraph/company-knowledge/tools/index_document.ts" title="tools/index_document.ts" />

      <ComponentSource src="registry/langgraph/company-knowledge/tools/search_knowledge.ts" title="tools/search_knowledge.ts" />

      <Step>
        Run `dawn check` after copying so route and tool metadata are regenerated.
        `dawn dev`, `dawn build`, and `dawn verify` also run the same discovery path.

## Customization [#customization]

* Edit `index.ts` to change the model, description, or system prompt.
* Add route-local tools under `tools/`; tool input and output types are inferred from TypeScript.
* Run `dawn verify` before deploying generated LangGraph artifacts.
