- `list_docs`: Use this to browse everything the documentation index holds when you have no specific query, or to see what topics exist before searching. Returns the indexed sections as entries of title, section and url, up to max_results.
- `search_docs`: Use this to answer a question about the product (auth, versioning, pricing, API surface, runbook catalog) from its own documentation, given a plain-English query. Returns {results}: ranked sections, each with title, section, a text snippet, a score and the real source URL, never fabricated content; empty if nothing matches.
