 "title": "Find the real failures in a long log without reading every line",
 "page_title": "How to find the real failures in a long log without reading every line with Quicksilver",
 "summary": "Have Jev mark which log lines report a failure, then pass Claude the collapsed result.",
 "who": "An engineer or on-call agent facing a log file with thousands of lines who needs the real errors fast.",
 "problem": "Reading a 3,000-line log line by line costs many Claude tokens and most lines are noise.",
 "outcome": "Claude receives the failing lines with repeated patterns collapsed into line-number ranges; the benchmark's noisy service log task reached 100% F1 with 95% fewer Claude tokens.",
 "steps": [
  "Get a Jev key at console.typesafe.ai and run `npx github:UditAkhourii/quicksilver`.",
  "Restart Claude Code so it can use the skill.",
  "Run `qs filter \"Does this line report a failure?\" app.log --lines` and replace app.log with your log file. (inferred, check the README)",
  "Check the receipt line at the end of the output for lines scanned, matches, and borderline items.",
  "Ask Claude to explain the matched line ranges, and review any ? lines by hand."
 ],
 "agent_prompt": "Using the repo UditAkhourii/quicksilver, run qs filter with the question \"Does this line report a failure?\" and the --lines flag on <log-file>. Summarize the matched line ranges and their likely causes. Verify that the receipt line reports the number of lines scanned.",

 "difficulty": "Intermediate",

 "caveat": "Logs whose labels encode unwritten policy, like the BGL supercomputer log in the benchmark, scored poorly, so test on a sample before trusting the results.",
