 "summary": "Feed a saved network capture to your agent to see requests, responses and the payloads they expose.",
 "who": "Developer debugging how an app talks to its server using a capture they already recorded",
 "problem": "A raw capture has hundreds of requests and no clear picture of what the app actually sends.",
 "outcome": "A readable breakdown of requests, responses and exposed payloads tied to source locations.",
 "steps": [
  "Export your traffic as a HAR file or a Fiddler Everywhere SAZ file.",
  "Run npx rea-agents setup and restart your agent.",
  "Ask the agent to analyze the capture with REA.",
  "Ask it to explain the calls behind the feature you are tracing."
 ],
 "agent_prompt": "Use REA to analyze the network capture at <path to .har or .saz>, list the key requests and responses, and explain which calls drive <feature>. Verify each claim against a specific request in the capture.",

  "For native binaries: Hopper, Ghidra or IDA installed locally",
  "For websites: a Chrome-family browser",
