The server provides 4 tools for Minecraft datapack validation with clear, domain-specific purposes. Tool naming follows verb_object patterns (validate_*, get_*, list_*) which is good. However, descriptions are adequate but terse (109-165 chars, below the 194-char baseline), lacking guidance on when to call each tool or dependencies between them. All tools have input schemas with proper types and enums, which is strong. Parameter descriptions are present and specific (e.g., 'The relative path to the JSON file within the datapack'). Output schemas are not explicitly documented in the source code provided, which is a significant gap. No error handling guidance is visible, tools return validation results but don't guide the LLM on failure recovery. The tools are read-only (no state mutation), which eliminates some complexity, but descriptions could better explain the intent and typical workflows.

• Add explicit output schema documentation for each tool. E.g., validate_json should document: {type: 'object', properties: {valid: boolean, errors: array<{path: string, message: string}>, warnings?: array}, required: ['valid', 'errors']}.
• Expand validate_full_datapack description from 'Validate an entire Minecraft datapack by analyzing its pack.mcmeta file and all JSON files within it' to include: 'Call this to perform a complete datapack audit. Returns a report of all validation errors and warnings. Slower than validate_json but catches pack-level issues.'
• Add dependency hints: 'To check supported versions before validation, call list_versions() first. To retrieve the schema for a specific JSON type, call get_json_schema().'
• Document error scenarios explicitly: 'If version is not found, returns a 404 error listing available versions. If JSON is malformed, returns a validation error with line/column hints.'
• Enforce the version/pack_format choice using JSON Schema oneOf constraint: 'oneOf': [{required: ['version']}, {required: ['pack_format']}] to make the relationship machine-checkable.
• Add per-parameter format constraints. E.g., version parameter: 'format: '^\d+\.\d+(\.\d+)?$'' (semver pattern) or describe as '1.20.1, 1.21, etc.'; pack_format: 'example: 94 or 94.1'.
• Document validate_json performance: 'Fast validation of a single JSON file. For full datapack validation, use validate_full_datapack().' This helps the LLM choose the right tool.
