Mnelyra provides 38 tools with explicit schemas and descriptions across harness, file, git, and Codex subsystems. Most tools have clear verb-noun naming (start_task, update_task, list_dir) and documented parameters with types. However, descriptions are often terse (20-50 chars), parameter descriptions lack detail on constraints and formats, and output schemas are not formally documented. Error handling is present but generic. The server demonstrates solid foundational structure but lacks the polish and LLM-optimization needed for A-grade quality.

• Expand tool descriptions to 100-200 characters. Include WHEN to use (e.g., 'Call after start_task to monitor progress'), WHAT it returns (e.g., 'Returns task object with status, steps, and timestamps'), and any prerequisites.
• Add min/max bounds to numeric parameters in descriptions. E.g., 'cursor: Pagination offset (0-based, defaults to 0)' and 'limit: Results per page (1-200, defaults to 50)'.
• Document output schemas explicitly. For each tool, add a 'Returns' section listing field names, types, and meanings. E.g., 'Returns: {task: {id: string, status: string, steps: string[]}, next_cursor: integer}'.
• Add destructive operation warnings to exec_command and apply_patch descriptions. E.g., 'WARNING: This executes arbitrary shell commands and can delete files. Always use dry_run=true first or request user confirmation.'
• Implement structured error responses with recovery hints. E.g., instead of 'Invalid task ID', return 'Task not found. Call list_task_events or task_context to find valid task IDs.'
