The Agent Skills Directory

[SAFE]: The skill is purely informational, providing guidelines for testing strategies such as unit testing, integration testing, property-based testing, and behavior-driven development (BDD).
[EXTERNAL_DOWNLOADS]: The skill references well-known testing frameworks and tools including Vitest, Jest, ESLint, QuickCheck, Hedgehog, and fast-check. These are industry-standard tools within the JavaScript/TypeScript and Haskell ecosystems.
[PROMPT_INJECTION]: The skill includes instructions for 'Adversarial Persona Lens' testing, which is a defensive methodology designed to help developers identify edge cases and potential injection vulnerabilities in their own code. These instructions do not target the agent's safety guardrails.
