SandboxMCP exhibits severe definition quality gaps across all four tools. Tool names lack action verbs (e.g., 'file-system' and 'process' are nouns, not verb_noun patterns). Descriptions are present but generic and lack LLM-optimization guidance. Critical issue: input schemas are inferred from code snippets rather than explicitly visible in tool registration. The 'file-system' tool accepts 'operation' as a free-form string instead of an enum, inviting hallucinated values. The 'process' tool exposes shell command execution with no input validation, sanitization, or error recovery guidance. No output schemas are documented. Error handling is absent, no guidance on retryability, user-fixable vs. fatal errors, or recovery paths.

• Rename tools to verb_noun pattern: 'get_weather' (good), 'check_health', 'read_file', 'write_file', 'list_directory', 'execute_command'. Each name must start with an action verb.
• Convert 'operation' parameter in file-system tool to an enum: {"type": "string", "enum": ["list", "read", "write", "delete"], "description": "File operation to perform..."}. Enums are self-documenting and prevent hallucination.
• Add explicit output schemas for all tools. Document return types, field names, and structure. E.g., get_weather returns {temperature: number, conditions: string, humidity: number}.
• Implement input validation and error recovery guidance. For 'process' tool: validate command syntax, set 5-second timeout, return actionable errors like 'Command timed out. Try a simpler command or increase timeout.' Sanitize against command injection.
• Expand 'health_check' description from 30 chars to 50-150 chars. Explain what 'healthy' means, when to call it, and what the response indicates. E.g., 'Returns server status (healthy|degraded|offline) and uptime. Call this first to verify the server is responsive before executing other tools.'
