4 use cases

  • Find where Claude Code tokens are wasted

    Run one report on your local logs to see savings ranked by how sure they are, in dollars.

    View prompt
    Run `npx optimaizr` from the optimaizr repo (github.com/blendbunjaku/optimaizr) on this machine and report the Clear waste and Re-reading the conversation figures. Verify that the savings are reported per month and that the three savings tiers are not added together.

  • Hold expensive Claude Code messages before they go

    Guard holds a message to an idle long conversation once, with its cost, and a cache countdown shows time left.

    View prompt
    In the optimaizr repo (github.com/blendbunjaku/optimaizr), run `optimaizr guard on` and then `optimaizr guard` on this machine. Report how many messages were held and the cost each would have written. Verify that a held message was not sent until it was sent again.

  • Track token use in your own Anthropic or OpenAI app

    Wrap your existing API client in one line so optimAIzr can read your app's calls.

    View prompt
    In the optimaizr repo, wrap the API client in <app path> with optimaizr.wrap, run the app once, then run `npx optimaizr` and report the Where it goes breakdown. Verify that the app still returns the same responses it returned before the wrap.

  • Check whether compacting at 200K actually saved money

    Apply the change, wait several days, then compare cost per prompt and each trade-off to the days before.

    View 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.
