What you can do with it
- Make Claude Code or Codex reply in short, answer-first sentences while keeping code exact
- Shrink logs, JSON, CSV and test output before the model reads them
- Switch individual features on or off and check what is active with simple commands
Make money with it
A freelance developer could lower their AI running costs and take on more client work within the same usage limits.
An idea, not financial advice. Check the licence before charging for anything built on it.
Ways a business could use it
- Cut the monthly cost of AI coding subscriptions or API use for a small development team
- Fit more work into usage limits on a Claude Pro or Max plan when building client projects
Can you use it commercially?

Things to check
- The headline savings figures are the project's own tests, so results will vary
- The Auto feature needs a free account
- It changes the settings of your existing coding agents, so review the proposed changes before accepting
- Very short answers may be harder for some users to read
