Critical failures across all dimensions. The server exposes only 2 tools (nx_plan_start, nx_task_add) with minimal definitions visible in src/mcp/server.ts. No input schemas, parameter descriptions, or output schemas are present in the provided source. Tool descriptions are trivial (10-20 chars). The codebase imports from '@moreih29/nexus-core/mcp' but actual tool registration logic is not visible, definitions appear to be generated or delegated to an external package. Per HARD SCORING RULES: tools with no visible input schema score 0 on schema; descriptions under 20 chars score 0-20 on description. Without seeing explicit tool definitions, per-tool scores are capped at 50, but the absence of any schema or parameter documentation in the provided source forces them lower.

• Expand tool descriptions to 50-200 characters. Example: 'nx_plan_start: Initiate a new planning session for multi-perspective analysis. Returns a session_id required for subsequent task additions. Requires a project context or goal statement.'
• Document all parameters with type, format, and constraints. Example: 'goal (string, required): The planning objective or problem statement (1-500 chars). session_id (string, optional): Existing session to extend; omit to create new.'
• Define output schemas explicitly. Example: 'Returns {session_id: string, created_at: ISO8601, status: "active", max_tasks: number}'.
• Add error handling guidance: 'If session_id is invalid, returns 400 with message "Session not found. Create a new session with nx_plan_start." Retry is safe.'
• Move tool definitions from '@moreih29/nexus-core/mcp' into this server's src/mcp/server.ts so schemas and descriptions are visible and maintainable in the repository.
