Single tool 'execute_skill_action' has a basic schema with one string parameter, but critical quality gaps undermine production readiness. Description is vague (70 chars, below 100-char minimum for clarity). Parameter 'query_payload' lacks actionable guidance on format, constraints, or examples. No output schema documented, responses are hardcoded JSON strings with no field definitions. No error handling, validation rules, or recovery guidance. Tool name uses 'execute' (generic verb) rather than domain-specific action. No parameter descriptions beyond the name. Composition is monolithic, a single catch-all tool that claims to handle 'Long-Horizon Coding & Memory operations' without decomposition.

• Add detailed parameter description for 'query_payload': specify expected JSON structure (e.g., {"operation": "...", "context": "..."}, required fields, valid operation types, and constraints. Example: 'JSON object with operation (string: retrieve|search|analyze) and context (string: max 1000 chars).'
• Document output schema explicitly. Define return object with fields: status (enum: SUCCESS|ERROR|PARTIAL), message (string), data (object with specific fields like retrieval_id, matched_index, fidelity_score), and error_code (string, if applicable).
• Expand tool description to 120-180 chars explaining: what domain problem it solves, when to call it vs other tools, and what the LLM should expect. Example: 'Retrieve telemetry and context from prior execution windows. Use this to debug test failures or analyze memory state. Returns matched snippets with fidelity scores.'
• Implement input validation with actionable error messages. If query_payload is not valid JSON, return: 'Invalid query_payload: expected JSON object. Example: {"operation": "retrieve", "context": "test_failure"}'. Categorize errors as retryable vs user-fixable.
• Decompose the monolithic tool into domain-specific tools: retrieve_telemetry (search prior context), analyze_memory (inspect state), search_context (find matching snippets). Each should have a single responsibility and clear input/output contract.
