browser_query_timeline
Query a recorded browser session timeline for events matching conditions like network errors, console messages, or text content, enabling retrospective debugging.
Instructions
TRACE-AS-DATABASE. Query the recorded session timeline for events matching a predicate — a retroactive logpoint you add AFTER the fact. E.g. every request that 5xx'd ({ kind: "network", statusGte: 500 }), every console error ({ kind: "console", level: "error" }), or anything mentioning a string ({ textContains: "checkout" }). Operates on a loaded past session if one is loaded, else the live session.
