The Agent Skills Directory

[EXTERNAL_DOWNLOADS]: The skill provides instructions for installing standard, well-known development dependencies from the NPM registry. These include jsdom, happy-dom, @vitest/coverage-v8, and @vitest/coverage-istanbul. These are official or widely recognized ecosystem packages necessary for testing.
[INDIRECT_PROMPT_INJECTION]: The skill documents a testing framework that, by design, processes and executes code from test files and configuration files. This constitutes an inherent attack surface for development-oriented AI agents.
Ingestion points: Test files (matching **/*.{test,spec}.ts), configuration files (vitest.config.ts or vite.config.ts), and environment variables via vi.stubEnv or process.env.
Boundary markers: None explicitly mentioned in the documentation, as is standard for testing tool references.
Capability inventory: The framework allows for arbitrary code execution in Node.js or simulated browser environments, file system writes for snapshots and coverage reports, and network operations if invoked within test suites.
Sanitization: No sanitization is performed by the tool on the code it is instructed to test, which is the expected behavior for a unit testing utility.
