Who it is forA developer or orchestrating agent that wants a mechanical quality check at the end of each coding task.
The problemDuplicated routines and quiet extra responsibilities pile up under fast edits, and tests do not catch them.
The outcomeA report of only the quality measures that got worse, so each one is fixed or justified in writing before the task closes.
What you need first
- A terminal with bash and curl to run the one-line installer
- A local clone or checkout of the repository you want to explore
- A coding agent that can run shell commands, such as Claude Code, Codex, Cursor, Windsurf, Gemini, opencode or aider
Steps
- Install Ripwire and add it to your path, as shown in the first use case.
- Change into the repository:
cd your-repo - Run the quality delta flag, named
--quality-delta, after your edits. Look up its exact arguments in the reference guide before running it. - Fix each reported regression, or write down a reason for keeping it.
- Run the tests and the edit check again before closing the task.
Prompt for your agent
Use ripwire on the repo at <path>. After your changes, run the --quality-delta flag and list every quality kind that got worse. Verify each one by reading the flagged code before you fix it or record a reason to keep it.
Caveat. The README says Ripwire is a floor for honesty and orientation and is not a substitute for measurement design, so it should sit alongside tests rather than replace them.
