Single tool 'execute_skill_action' has a reasonable description (97 chars, within 10-1024 range) and three parameters with type definitions. However, critical gaps undermine quality: (1) parameter descriptions are minimal (10-20 chars each, below the 72-char baseline); (2) no output schema documented, LLMs cannot plan downstream calls or extract structured data; (3) no error handling guidance; (4) tool name uses 'execute' + 'action' (generic verbs) rather than domain-specific action like 'anonymize_data' or 'generate_synthetic_records'; (5) privacy_level enum is declared but dataset_schema lacks structure guidance. The implementation in client.py shows mock data but no actual validation, error recovery, or schema enforcement.

• Document the output schema explicitly. Example: {"anonymization_rules_applied": [{"field": string, "method": string}], "synthetic_records_generated": integer, "sample_output": array, "compliance_standards": array}. This enables LLMs to extract and chain results.
• Expand parameter descriptions to 50-100 chars each. For dataset_schema, add: 'JSON object with keys matching field names (e.g., {"email": {"type": "string"}, "age": {"type": "integer"}}). Required fields: type, description.'
• Rename tool to 'anonymize_and_generate_data' or split into two tools: 'anonymize_dataset' (input: dataset, rules) and 'generate_synthetic_records' (input: schema, count, privacy_level). Single-responsibility tools are easier for LLMs to reason about.
• Add validation and error handling. Return structured errors: {"error": "Invalid privacy_level", "valid_options": ["GDPR", "CCPA", "HIPAA_Safe_Harbor"], "suggestion": "Did you mean GDPR?"}. This guides LLM self-correction.
• Add a 'dry_run' boolean parameter (default false) to preview anonymization rules and sample output before generating full records. Prevents accidental data loss and matches the confirmation-request pattern.
