Single tool 'execute_skill_action' has a minimal description (97 chars) that lacks actionable context for LLM selection. Input schema is present but parameter 'query_payload' has only a generic description ('Input execution payload for this skill') with no format, constraints, or examples of valid payloads. No output schema is documented, the tool returns a hardcoded JSON string with no structure definition. The tool name uses a generic verb ('execute') rather than a domain-specific action verb. No error handling, no recovery guidance, and no indication of what the tool actually does beyond vague 'Autonomous Code Synthesis skill operations'. The implementation is a stub that always returns success regardless of input.

• Rename tool to a domain-specific action verb. If the tool performs symbol refactoring, name it 'refactor_symbol_rename'. If it analyzes code, name it 'analyze_code_semantics'. The name should convey the action without reading the description.
• Expand parameter 'query_payload' description to specify expected format: JSON object with fields like 'workspace_files' (dict), 'old_symbol' (string), 'new_symbol' (string). Include a concrete example structure.
• Document the output schema explicitly. Specify that the response contains fields: 'refactor_job_id' (string), 'old_symbol' (string), 'new_symbol' (string), 'files_modified_count' (integer), 'atomic_diff_manifest' (array of objects with 'file' and 'diff' fields), 'refactor_patch_url' (string).
• Add error handling that returns structured errors with recovery guidance. E.g., if 'old_symbol' is not found, return: 'Symbol not found. Available symbols in workspace: [list]. Did you mean one of these?'
• Expand tool description to 150-200 chars explaining: what the tool does (semantic symbol renaming across a codebase), when to use it (when refactoring code to rename classes/functions), and what it returns (a patch manifest with diffs for each affected file).
