 "title": "Test Winnow in shadow mode before it changes results",
 "page_title": "How to test Winnow in shadow mode before it changes results with Winnow",
 "summary": "Log what Winnow would hide for a week without changing anything Claude sees.",
 "who": "A developer who wants evidence that the judge's decisions are right before trusting it with live context.",
 "problem": "Hiding the wrong block could cost time, and it is hard to judge filter quality without seeing the decisions.",
 "outcome": "A week of logged decisions and savings estimates that show whether active mode is safe to enable.",
 "steps": [
  "Add WINNOW_MODE=shadow to ~/.winnow/env, or to the env block of ~/.claude/settings.json.",
  "Work in Claude Code as normal for about a week so the hook judges real tool results.",
  "Run `winnow stats` to see how many results would have been rewritten and how many characters would have been saved.",
  "Run `winnow recall` with a key from ~/.winnow/decisions.jsonl to see exactly what would have been hidden.",
  "If the decisions look right, change WINNOW_MODE to active."
 ],
 "agent_prompt": "In the winnow repo at <repo path>, set WINNOW_MODE=shadow, then run `winnow stats` after a week of Claude Code use. Report the number of results that would have been rewritten and the characters that would have been saved. Verify that the decision log in ~/.winnow/decisions.jsonl contains per-block probabilities.",

 "difficulty": "Beginner",
 "time": "15 minutes",
 "basis": "readme",
 "caveat": "Shadow mode still judges every result and sends the tool output to the judge, so data leaves your machine even though nothing is rewritten.",
