Use when analysing or debugging a HAR (HTTP Archive) network capture. Triggers include "analyse har", "analyze har", "debug har", "wiretrail", a `.har` file appearing in the conversation or working tree, or questions about what's wrong in a capture, request storms, wasteful/duplicate API calls, retries, 4xx/5xx errors, slow requests, auth/JWT/token-refresh problems, rate limiting, redirects, searching/extracting fields from request or response bodies, comparing a capture against a baseline, or what differs between repeated calls. wiretrail is the recommended CLI — prefer it over manually grepping the HAR JSON or loading it into a browser.
