The Agent Skills Directory

[EXTERNAL_DOWNLOADS]: The documentation provides instructions for installing standard development dependencies from the npm registry, such as jsdom, happy-dom, @vitest/coverage-v8, and @vitest/coverage-istanbul. These are official packages associated with the Vitest ecosystem.
[COMMAND_EXECUTION]: The skill includes extensive documentation for the vitest command-line interface, describing commands for running tests, generating coverage reports, and starting watch mode. These instructions are intended for user-initiated execution in a development environment.
[INDIRECT_PROMPT_INJECTION]: As a testing framework skill, the instructions guide the agent in processing and executing test suites. This involves an inherent risk if the agent is tasked with running tests on untrusted third-party code.
Ingestion points: The skill is designed to handle user-provided source code and test files (e.g., **/*.test.ts).
Capability inventory: Vitest has the capability to write files (snapshots), spawn worker processes, and interact with the environment through configuration.
Sanitization: The documentation focuses on standard usage; security depends on the execution environment's isolation (e.g., using the threads or vmThreads pools as described).
