The MCP server exposes 8 Roblox game control tools with partial but incomplete schema coverage. Tool names follow verb_noun patterns well (get_*, execute_, delete_, set_), and descriptions are present and reasonably detailed (avg ~150 chars). However, critical issues undermine production readiness: (1) Parameter descriptions are missing for most tools, while path and code parameters have descriptions, many tool inputs lack explanatory text for LLMs. (2) Input schemas visible in package.json show typed parameters but no formal JSON Schema validation rules (min/max bounds, enum constraints, or format specifications). (3) Output schemas are completely undocumented, LLMs cannot infer what fields to expect in responses. (4) Error handling is unspecified, no guidance on recovery actions, retryability, or what happens when operations fail. (5) Destructive tools (delete_instance) and high-risk operations (execute_code, teleport_player) lack confirmation patterns or dry-run modes. (6) No pagination, rate limiting, or result caps for list-like tools (get_game_tree). Tools are domain-appropriate but definition quality falls short of production standards.

• Document output schema for every tool. Include JSON examples showing field names, types, and nested structure. Example: get_bridge_status returns {status: 'connected'|'disconnected', executorName?: string, uptime?: number}.
• Implement confirmation pattern for destructive tools. Add a 'dry_run' boolean parameter to delete_instance and require explicit confirmation. Return a confirmation token that must be passed to execute the deletion.
• Add error handling and recovery guidance to each tool description. Example: 'If path not found, available parents are: [...]. Call get_game_tree() to discover valid paths.'
• Document result limits and implement pagination. For get_game_tree, cap depth and return node count. For get_properties, limit to 50 properties per call and offer next_cursor pagination.
• Refactor rbxdev_set_property: replace separate value/valueType parameters with a typed union or use separate parameters per type (e.g., set_property_string, set_property_number). This eliminates type mismatch bugs.
• Add validation constraints to parameter descriptions. Example: 'code must be valid Luau syntax (typically 10 - 10000 chars). Returns error if syntax invalid.'
• Specify timeout behavior for execute_code. Example: 'Execution times out after 5 seconds. Returns {success: false, error: 'timeout', elapsed_ms: 5000}.'
• Clarify path parameter format with examples. Example: 'path is an array of instance names from root. Example: ["Workspace", "Folder", "Part"]. Use get_game_tree() to discover structure.'
