Significant gaps across naming, descriptions, and schemas. Tool names lack consistent verb prefixes (e.g., 'think_steps' vs 'get_current_time'). Descriptions are present but minimal (10-50 chars), below the 50-200 char baseline for LLM optimization. Input schemas visible in code but lack proper JSON Schema structure with type constraints and validation rules. No output schemas documented. Error handling is generic ('Error: {e}') with no recovery guidance. Mock implementations (Jira, GitHub, Slack) return unstructured text instead of structured JSON. No parameter validation or constraint documentation.

• Add structured JSON output schemas to all tools. E.g., read_file should return {"content": string, "size_bytes": int, "encoding": string} instead of raw file text.
• Expand descriptions to 50-150 chars with WHAT/WHEN/WHY. E.g., 'Store a key-value pair in ephemeral memory. Use before retrieve() to cache data across tool calls. Keys are case-sensitive; overwrites existing values.'
• Implement proper error handling with recovery hints. E.g., 'File not found: /path/to/file. Check path spelling or use list_directory() to explore available files.'
• Replace mock implementations with structured responses. E.g., create_ticket should return {"ticket_id": "DEMO-ABC123", "url": "https://...", "status": "created"} as JSON, not a formatted string.
• Rename ambiguous tools: 'delete' → 'delete_memory_key', 'think_steps' → 'reason_step_by_step', 'brainstorm' → 'generate_ideas'. Add parameter constraints (enums, min/max) to all numeric and categorical inputs.
