Tool definitions are not visible in the provided source code. The server imports toolRegistry from './tools/_registry.js', which was not included. The src/server.ts excerpt shows tool registration logic (wrapping read/mutation tools, checking remoteEnabled flag) but no actual tool definitions, schemas, descriptions, or parameters. Without access to the registry, all tool quality metrics cannot be evaluated. This is a critical blocker for assessment.

• Provide the complete './tools/_registry.js' file showing all tool definitions, schemas, and descriptions for evaluation.
• Ensure every tool has a description of 50 - 200 characters explaining WHAT it does, WHEN to use it, and any prerequisites (baseline: avg 194 chars).
• For each parameter, include a type (string, number, boolean, enum) and a description explaining what it controls and valid values/ranges.
• Document output schemas showing all returned fields, their types, and whether they are needed for downstream tool chaining.
• Add error handling that tells the LLM what to do next: 'User not found. Try search_users() with a partial name.' instead of raw error codes.

• Relies on Logging (deprecated) - log to stderr or use OpenTelemetry
