Use when you need to add or review fuzz testing for Java APIs with CATS — including contract-driven negative testing, malformed payload validation, boundary input exploration, CI integration, reproducible failures, and local execution guidance. This should trigger for requests such as Add fuzz testing to a Java project; Use CATS for API negative testing; Review CI quality gates for API contract robustness; Improve boundary and malformed input test coverage; Run CATS fuzz tests against an…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Java fuzz testing with CATS Design and implement contract-driven fuzz testing for Java APIs using CATS to uncover edge cases and input-validation defects early. **What is covered in this Skill?** - CATS setup using a trusted local jar or prebuilt image and baseline command usage for OpenAPI-driven fuzzing - Negative testing strategy for invalid payloads, missing fields, wrong types, and malformed values - Boundary testing for size, range, format, and enum constraints - CI integration patterns with actionable logs and reproducible failures - Local execution workflow for contributors before opening pull requests - Reporting and triage practices for fuzzing findings **Scope:** Focus on HTTP API fuzzing and contract validation with CATS. Use this skill to define practical, repeatable checks in both local and CI workflows. ## Constraints Before applying any fuzz testing changes, ensure the project compiles. If compilation fails, stop immediately. After implementation, regenerate skills and run verification. - **MANDATORY**: Run `./mvnw compile` or `mvn compile` before applying any change - **SAFETY**: If compilation fails, stop immediately and do not proceed …

How to install
mdr add jabrena/plinth/703-technologies-fuzzing-testing@sha256:2b240f4221389f83The line at the top of this page pins the label v0.19.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
