What information is returned when a Gravatar is found?

The skill provides the MD5 hash of the email, the direct avatar image URL, and a link to the user's public Gravatar profile.

Does this skill cache the results?

Yes, it caches responses for 24 hours to improve performance and reduce redundant API calls. You can use the --no-cache flag to force a fresh check.

How does the Gravatar Check skill verify existence?

It performs a HEAD request to Gravatar's servers using a 404 default parameter, allowing it to confirm existence without the overhead of downloading the actual image.

Does a 'Not Found' result return an error code?

No, if an email does not have a Gravatar, the skill still returns an exit code of 0 because the check itself was performed successfully.

Can I use this for bulk email verification?

Yes, the skill can be easily scripted within the Claude Code environment to loop through a list of email addresses for batch verification.

概要

Gravatar Check is a specialized Claude Code skill that enables developers to programmatically verify if an email address is associated with a Gravatar profile. By performing optimized HEAD requests and utilizing a 24-hour caching mechanism, it efficiently determines avatar availability without downloading unnecessary assets. This tool is essential for developers wanting to validate email addresses against a global avatar database, conditionally display user photos in applications, or enrich user metadata during bulk processing tasks.
