The Agent Skills Directory

[SAFE]: The skill acts as a documentation reference for the date-fns library. All instructions follow library best practices, such as validating dates before formatting and using correct Unicode tokens.
[EXTERNAL_DOWNLOADS]: The skill references the installation of standard, well-known Node.js packages including date-fns, @date-fns/tz, and @date-fns/utc. All external links point to official project websites or reputable source code repositories on GitHub.
[INDIRECT_PROMPT_INJECTION]: The skill identifies a data ingestion surface where user-provided strings are parsed into date objects.
Ingestion points: The parseISO(userInput) example in references/setup-core.md demonstrates handling external data.
Boundary markers: The skill encourages the use of logical checks like isValid() to verify parsed data.
Capability inventory: There are no scripts or tools within the skill that perform dangerous operations (such as command execution or network requests) using this parsed data.
Sanitization: Documentation explicitly instructs developers to validate inputs using isValid() before using the data in formatting or database operations.
