Single tool 'execute_skill_action' has a minimal schema with only one string parameter. Description is present (95 chars) but lacks critical context: no explanation of what 'query_payload' should contain, no guidance on expected format or structure, no error recovery hints. Parameter 'query_payload' has a generic description ('Input execution payload for this skill') that does not specify format, constraints, or examples. No output schema documented, the tool returns a hardcoded success message with no structure. No error handling, no validation, no guidance for LLM on when to use this tool vs alternatives. The tool appears to be a stub implementation rather than a production-ready skill.

• Expand tool description to 100-200 chars explaining: (1) What the tool does (e.g., 'Executes browser automation tasks using self-healing DOM selectors that adapt to UI changes'), (2) When to use it (e.g., 'Use when you need to interact with web elements that may have changed class names or structure'), (3) What it returns (e.g., 'Returns execution status, result data, and confidence scores').
• Document 'query_payload' parameter with explicit format: specify whether it expects JSON, a string command, or a structured object. Include constraints (max length, required fields if JSON). Example: 'query_payload (string, required): JSON-encoded action object with keys: action (string: click|type|scroll), selector (string: CSS selector), value (string, optional: text to type). Max 5000 chars.'
• Add output schema documentation in tool description or as a separate field. Specify: 'Returns object with fields: status (string: SUCCESS|ERROR), message (string: human-readable result), result_data (object, optional: action-specific output), confidence_score (number 0-1, optional: reliability estimate)'.
• Implement actual error handling and validation. Return structured errors with actionable guidance: 'Invalid query_payload: expected JSON object with action field. Valid actions: click, type, scroll. Example: {"action": "click", "selector": "button.submit"}'.
• Add parameter for optional 'timeout' (integer, 1-60 seconds, default 30) and 'retry_count' (integer, 0-5, default 1) to give LLM control over execution behavior and resilience.
