ddmin

Fixture-based approval testing CLI for agent-managed codebases

Find the cause of a regression by binary search — over commits, inputs, config, dependencies or test ordering. A Claude Code skill with working ddmin and predicate-validation tooling.

CLI that minimizes failing operation sequences using classic delta debugging (ddmin), with deterministic scenarios, independent verification, and SVG reduction traces.

Turn a flaky bug report into a minimal, deterministic reproduction.

Mini-fuzzer with crash-input minimizer

Delta debugging for AI failures. Shrink a failing agent context to the smallest reproducer someone else can run.
