Critical gaps across all dimensions. No input schemas visible in provided source code, cannot verify parameter types, constraints, or descriptions. Tool descriptions are present but generic (10-50 chars), lacking LLM-optimized guidance on WHEN to use each tool vs. similar ones. No output schemas documented. No error handling patterns visible. All 18 tools appear to be READ_ONLY, but descriptions do not explicitly state this or explain recovery paths for common failures (e.g., 'wallet not found'). Tool names follow verb_noun convention (positive), but lack specificity, e.g., 'query-events' vs. 'search-events-by-type' is ambiguous. No evidence of parameter validation, pagination limits, or response field documentation.

• Provide complete src/tools/*.ts files showing actual tool registration, input schemas (JSON Schema with types, enums, constraints), and output schemas. Current evaluation is based on inferred metadata only.
• Expand tool descriptions to 50 - 200 characters. Include WHEN to use (vs. similar tools), WHAT it returns, and any prerequisites. Example: 'query-events: Search loyalty events by type, wallet, or date range. Returns paginated results with event_id, wallet_id, type, timestamp. Use before get-wallet-activity to filter by event type.'
• Document output schemas for all tools. Specify field names, types, and which fields are required for downstream tool chaining (e.g., wallet_id, rule_id). Include pagination fields (total_count, next_cursor) for list tools.
• Add error handling patterns. For each tool, document common failure modes and recovery guidance. Example: 'If wallet not found, call check-wallet(wallet_id) first to verify it exists. If rule evaluation fails, call get-rule-details(rule_id) to inspect the rule logic.'
• Implement parameter validation and constraints. Add enums for status/type fields, min/max for numeric params, and regex patterns for IDs. Document in descriptions: 'event_type: one of [purchase, referral, badge_earned, points_redeemed] (required)' and 'limit: 1 - 100 (default 20)'.
