703-technologies-fuzzing-testing
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.

W012: Unverifiable external dependency detected (runtime URL that controls agent)
What this means
The skill fetches instructions or code from an external URL at runtime, and the fetched content directly controls the agent’s prompts or executes code. This dynamic dependency allows the external source to modify the agent’s behavior without any changes to the skill itself.
Why it was flagged
Potentially malicious external URL detected (high risk: 0.90). The cats Dockerfile fetches and extracts remote code during build via "https://github.com/Endava/cats/releases/download/cats-${CATS_VERSION}/cats_uberjar_${CATS_VERSION}.tar.gz", which is a runtime dependency that provides the CATS uberjar later executed (java -jar), so the skill fetches and runs remote code.
