- When performing large payload sprays or fuzzing, encapsulate the entire spraying loop inside a single python or terminal tool call (e.g., a Python script using asyncio/aiohttp). Do not issue one tool call per payload.
- Favor batch-mode CLI tools (sqlmap, ffuf, nuclei, zaproxy, arjun) where appropriate and check traffic via the proxy when beneficial
+REMINDER: Always close each tool call with before going into the next. Incomplete tool calls will fail.
