 "page_title": "How to check whether compacting at 200K actually saved money with Optimaizr",
 "summary": "Apply the change, wait several days, then compare cost per prompt and each trade-off to the days before.",
 "who": "A Claude Code or Codex user who wants proof that a context-size change cut cost before keeping it.",
 "problem": "A cost saving can come with more tool calls, errors or waiting, and it is unclear whether the change caused them.",
 "outcome": "A before and after table where every worse row is marked as a trade-off, plus a one-command way to undo the change.",
 "steps": [
  "Run `optimaizr apply context-compaction`.",
  "Use Claude Code or Codex normally for several days.",
  "Run `optimaizr results` to compare the days after with the days before.",
  "If the trade-offs are not worth it, run `optimaizr undo context-compaction`."
 ],
 "agent_prompt": "In the optimaizr repo, after context compaction has been applied for several days, run `optimaizr results` on this machine and report cost per prompt before and after. Verify that every row that got worse is marked as a trade-off before you draw a conclusion.",

 "difficulty": "Beginner",
 "time": "15 minutes",
 "basis": "readme",
 "caveat": "The README says part of any saving may already have been under way, because the baseline is the days before the change.",
