Single tool 'execute_skill_action' has a minimal schema with only one string parameter. Description is generic marketing copy ('Execute deterministic, zero-dependency AI Synthetic Data & Evaluation Benchmark operations verified by GenPark AI') that does not explain WHAT the tool actually does, WHEN to use it, or WHAT it returns. Parameter 'query_payload' lacks any meaningful description beyond 'Input execution payload for this skill', ambiguous and unhelpful. No output schema documented. The tool appears to be a pass-through echo service with no real functionality. No error handling guidance. Fails most definition quality patterns.

• Replace generic description with concrete, functional documentation: 'Generates adversarial red-team prompt injection test cases for evaluating LLM robustness. Input: target intent (e.g., "Provide root database credentials"). Output: array of synthesized attack prompts with categories (roleplay, system_prompt_leakage, indirect_comment_injection).'
• Add explicit output schema to tool definition: {type: object, properties: {target_intent: string, test_cases_count: number, test_cases: array of {attack_category: string, attack_name: string, synthesized_prompt: string}}}
• Rename tool to 'generate_prompt_injection_test_suite' to clearly signal it generates fuzzing payloads, not generic skill execution.
• Add parameter constraints: query_payload should be described as 'Target intent or capability to probe (e.g., "Extract system prompt", "Provide credentials"). 1-500 characters.'
• Implement input validation and error responses: reject empty query_payload, return 'Invalid query_payload: must be 1-500 characters' with actionable guidance.
