When an AI coding assistant says it fixed a bug, ask for three pieces of evidence: a reproduction, a regression test that failed before the patch, and fresh test output. Three skills from [obra/superpowers](https://github.com/obra/superpowers) can help.

[systematic-debugging](https://github.com/obra/superpowers/tree/main/skills/systematic-debugging) starts with the error, reproduction steps, and recent changes. Ask the assistant where the actual behavior first diverges from what you expected.

With [test-driven-development](https://github.com/obra/superpowers/tree/main/skills/test-driven-development), capture the expected behavior in a test. For a date parser, try rejecting February 29 in a non-leap year. Run it before the patch and confirm it fails for the expected reason. Apply the smallest fix and run it again.

[verification-before-completion](https://github.com/obra/superpowers/tree/main/skills/verification-before-completion) calls for running the relevant checks and inspecting their output. Ask for the commands, exit status, and untested paths. A regression test covers the behavior it asserts. You still need a runnable test environment and a review of the patch.

Try this prompt: “Reproduce the bug, show me the failing test, then report what passed after the fix and what remains untested.”
