The Agent Skills Directory

[SAFE]: The skill provides documentation on unit testing best practices, including when to test, what to avoid, and how to use existing test helpers. It contains no executable code and serves purely as a set of instructions for a human or AI agent working in the repository.
[COMMAND_EXECUTION]: The documentation includes standard commands for running tests and linters, such as cargo nextest and cargo clippy, as well as repository-specific scripts like ./script/presubmit and ./script/format. These are typical for developer-oriented workflows and are used as intended for the skill's purpose.
