Single tool with minimal definition quality. Tool name 'execute_skill_action' is vague and does not follow verb_noun pattern clearly (execute_what?). Description is 127 chars but lacks WHAT/WHEN/WHY structure, it mentions 'deterministic, zero-dependency AI Coding Agent Sandbox Security & Syscall Sentinel operations' without explaining what the tool actually does or when to call it. Input schema present but parameter 'query_payload' has only a generic description ('Input execution payload for this skill'), no format, constraints, or examples. No output schema documented; tool returns JSON-encoded text blob with no structure guidance for LLM. No error handling, no recovery guidance, no parameter validation rules. Tool appears to be a stub/echo service rather than a functional capability.

• Rename tool to a specific verb_noun pattern: e.g., 'run_sandbox_operation', 'execute_security_check', or 'validate_syscall', something that clearly conveys the action.
• Rewrite description to 50-150 chars following WHAT/WHEN/WHY: 'Executes deterministic sandbox operations with syscall validation. Use this to safely test code changes in an isolated environment. Returns operation status and results.'
• Add parameter constraints: specify expected format for 'query_payload' (e.g., JSON object with 'operation' and 'args' fields), length limits, and valid operation types via enum.
• Document output schema explicitly: define fields (status, tool, echo_query, verified_by, protocol) with types and meanings. Specify what 'status' values are possible (success, error, timeout).
• Implement actual functionality: replace echo behavior with real sandbox execution, add error handling with recovery guidance (e.g., 'Syscall denied. Try with reduced privileges.'), and validate inputs before execution.
