Three well-named, verb-prefixed tools (list_skills, find_skill, read_skill) with clear, actionable descriptions (120 - 180 chars). All tools have complete JSON Schema input definitions with typed parameters and descriptions. Schemas include proper constraints (minLength, maximum, integer, positive). Output structure is documented via structuredContent returns. However, output schemas are not formally documented in tool metadata, and error handling lacks recovery guidance. No tool annotations (readOnlyHint, idempotentHint) despite all three being read-only operations.

• Add formal outputSchema declarations to each tool registration. Document list_skills returns {skills: [{name, description, vertical}], total}, find_skill returns {matches: [{name, score}]}, read_skill returns {name, description, content}.
• Add readOnlyHint: true to all three tool definitions in registerSkillTools(). This signals to MCP clients that these tools are safe to cache and retry without side effects.
• Document error cases and recovery paths. E.g., 'If read_skill returns 404, call list_skills(vertical=...) to discover available skills in that category.'
• Clarify find_skill vs list_skills in descriptions. E.g., find_skill: 'Use semantic search when you have a natural-language question. Use list_skills() for metadata-based filtering (vertical, keyword).'
• Cap list_skills results at 50 and add offset/cursor pagination. Document: 'Returns up to 50 matches. Use offset parameter to fetch additional results.'

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