Three tools with clear verb-noun naming (mcphub_get_server, mcphub_reload_server, mcphub_health_check). All have descriptions and input schemas visible in registry.ts. However, descriptions are brief (10-50 chars), lacking context on WHEN to use each tool and what downstream actions they enable. mcphub_health_check has no documented input schema. Parameter descriptions exist but are minimal. Output schemas are not documented in the source provided. Error handling and recovery guidance are absent. Tool composition is reasonable (single responsibility), but descriptions fall short of LLM-optimized standards (target 50-200 chars per pattern:tool-description).

• Expand tool descriptions to 80-150 characters. Include WHAT the tool does, WHEN to use it (vs similar tools), and key output fields. E.g., 'Retrieve current configuration and status of a named MCPHub server. Use this to check if a server is running before attempting reload. Returns server_id, status, version, and config_hash.'
• Document output schemas for all tools. Specify which fields are returned, their types, and which are required for downstream tool calls. Include in registry.ts or a separate schema file.
• Add input validation constraints to parameter descriptions. E.g., 'serverName (string, 1-255 chars, alphanumeric + hyphens, case-insensitive). Example: my-mcphub-server'.
• For mcphub_health_check, define and document an input schema (even if empty/minimal). Specify what the tool returns (e.g., status: 'healthy'|'degraded'|'unhealthy', uptime_seconds, version).
• Add error handling guidance. E.g., 'If reload fails with 'server not found', call mcphub_get_server first to list available servers. If reload times out, check server logs via [future log_tool].' This guides LLM recovery.
