Four tools with mixed quality. install_skill and build_release_manifest have reasonable descriptions (80-120 chars) and structured schemas with typed parameters and enums. Parameter descriptions are present but sparse. No error handling guidance, no output schemas documented, and no tool annotations. Naming is verb-forward but generic (validate_*, build_*). Overall definition quality is below median due to missing schemas and output documentation.

• Add explicit input schemas to validate_repo and validate_translation_sync. Even if they accept no parameters, declare 'input: {"type": "object", "properties": {}, "required": []}' for clarity.
• Document output schemas for all tools. E.g., install_skill should return {"type": "object", "properties": {"destination": {"type": "string"}, "files_installed": {"type": "integer"}, "status": {"type": "string"}}}.
• Add tool annotations: install_skill and build_release_manifest are destructive (destructiveHint: true); validate_repo and validate_translation_sync are read-only (readOnlyHint: true).
• Expand parameter descriptions with format/constraint details. E.g., 'artifact: Array of ROLE=PATH pairs (e.g., ["binary=/path/to/file.bin", "config=/path/to/config.json"]). Roles must match artifact roles in manifest schema.'
• Add error handling guidance. E.g., install_skill: 'If destination exists, error is fatal, user must move/delete it first. If dry_run fails, check file permissions and disk space.'
