Relay Central API has 8 tools with complete input schemas and descriptions. Naming follows verb_noun convention (register, upload_skill, search, get_skill, update_skill, delete_skill, post_review, health). Descriptions are present and substantive (avg ~150 chars), exceeding the 10-char minimum. However, output schemas are not documented in the source code, responses are inferred from context but not explicitly defined. Parameter descriptions are present but some lack constraint details (e.g., search 'limit' lacks explicit 1-50 range in description text, only in schema). Error handling is not visible in the provided code. No tool annotations (readOnlyHint, destructiveHint, idempotentHint) are present. Security is reasonable (API key via X-Relay-Agent-Id header, rate limiting), but no explicit permission gates or audit logging visible.

• Document output schemas for all tools. For search, specify: {skills: [{skill_id, name, description, score}], total_count, next_cursor}. For register, specify: {agent_id, secret}. Include field types and descriptions.
• Add tool annotations to FastAPI route definitions. Use Pydantic field metadata or custom decorators to mark delete_skill as destructiveHint=true, search as readOnlyHint=true, and upload_skill as idempotentHint=false.
• Expand parameter descriptions with explicit constraints. E.g., search 'limit' → 'Maximum results to return (1-50, default: 5)'. Include min/max for numeric params and valid enum values in text.
• Implement error recovery guidance. When get_skill returns 404, respond: 'Skill not found. Try search() with a keyword to find similar skills.' When update_skill fails due to permission, respond: 'Only the original uploader can modify this skill.'
• Add optional dry_run parameter to update_skill and delete_skill. When dry_run=true, return what would change without committing. This prevents accidental data loss.
