Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full behavioral burden. "Read" implies a safe non-mutating call and "this server instance project" clarifies that it resolves the server's configured project rather than the cwd, but it says nothing about failure behavior when no Solhint config exists, caching, precedence resolution, or the shape of the returned data.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
