description: Use when querying current technical documentation with Context7 CLI.
---

Resolve the requested library identity with the installed ctx7 CLI, then query
narrowly for the requested version and fact. Use the CLI's current help for
command syntax. Return the resolved identity, version, relevant source locator,
and the evidence state required by the canonical Librarian policy.

That policy owns Context7-first enforcement, allowed fallback reasons, and
decision authority. Tool documentation supplies facts; Root owns material
product, architecture, dependency, compatibility, and implementation decisions.
