Skills for working with test-case reducers, especially writing good interestingness tests. Prioritizes shrinkray but applies to any reducer (creduce, cvise, lithium, etc.).
Diagnose problems with shrinkray test-case reduction — unexpected results, reduction getting stuck, slippage to wrong bugs, or interestingness test issues. Use when reduction output is surprising or reduction is not making progress.
Guide the user through setting up and running test-case reduction with shrinkray. Use when the user has a file that triggers a bug and wants to minimize it.
Help write an interestingness test for shrinkray (test-case reducer). Use when the user needs to reduce a test case, write or fix an interestingness test, or is working with test-case reduction.
This is a skill for teaching agents to use test-case reducers, especially shrinkray.
It's currently extremely experimental and mostly untested, so you'll likely run into problems when you try it in practice. When you do, please ask your agent to reflect on the problems it ran into, refine the skill, and open a pull request for you.
