Server has 7 tools with basic schemas and descriptions, but significant gaps limit production readiness. All tools are READ_ONLY and lack error handling guidance. Descriptions are present but generic (avg ~80 chars, below 194-char baseline). Most parameters lack descriptions entirely. No output schemas documented. No tool annotations (readOnlyHint, etc.). Parameter validation rules not stated. Tool composition is reasonable (single responsibility), but descriptions don't explain WHEN to use each tool or dependencies between them.

• Add output schema documentation to every tool. Example for get_project_info: 'Returns {"name": string, "version": string, "project_path": string, "settings": object}'. This enables LLMs to plan downstream calls.
• Add parameter descriptions for all inputs. Example: 'query (string, 1-256 chars): Fuzzy search pattern. Matches file names and paths. Returns up to 50 results sorted by relevance.'
• Add error handling guidance to tool descriptions. Example: 'If Godot API is unreachable, returns error with 'Godot editor not running' message. Retry after 5 seconds or ask user to start Godot.'
• Implement tool annotations in the Tool object. Set readOnlyHint=true for all 7 tools to signal to clients that these are safe to call without user confirmation.
• Clarify tool selection criteria. Add to get_filesystem_tree: 'Use this to explore project structure. Use search_files for targeted lookups by name.' Add to uid_to_project_path and project_path_to_uid: 'Use these to convert between Godot UID and res:// path formats when working with asset references.'
