Single tool 'run' has critical definition gaps. Description is present but minimal (56 chars, below 10-char baseline for clarity). Input schema visible with 'code' and 'session_id' parameters, but both lack descriptions, violating the requirement that every parameter must have a description. No output schema documented. Tool performs irreversible code execution (RISK: IRREVERSIBLE) but description does not warn of this or suggest confirmation patterns. No error handling guidance. Naming 'run' is generic and violates verb_noun convention (should be 'execute_python_code' or similar). Tool definition is visible in source, so not capped at 50, but quality is poor.

• Rename tool from 'run' to 'execute_python_code' to follow verb_noun convention and clarify intent.
• Add descriptions to 'code' (e.g., 'Python source code to execute. Must be valid Python 3.11+ syntax.') and 'session_id' (e.g., 'Optional session ID to maintain state across calls. If omitted, code runs in a fresh environment.').
• Document output schema: return object with fields like 'stdout' (string), 'stderr' (string), 'exit_code' (int), 'result' (any), 'execution_time_ms' (int).
• Add warning to tool description: 'WARNING: This tool executes arbitrary Python code. Ensure code is safe before execution. Consider using a dry-run or confirmation step for destructive operations.'
• Implement error handling that returns structured errors with recovery guidance, e.g., 'SyntaxError on line 5: invalid syntax. Check code and retry.' or 'Execution timeout after 30s. Code may be in infinite loop.'
