Hi @crazywoola, thanks for the review!

Fixed in v0.0.2:

• Added dify_plugin>=0.5.0 to requirements.txt
• Bumped manifest version to 0.0.2

Could you please re-run the pre-check workflow when you get a chance? Thanks!

Hi @crazywoola, friendly follow-up — would you be able to re-run the pre-check workflow when you have a moment?

The two issues from the first review have been addressed:

• Added dify_plugin>=0.5.0 to requirements.txt
• The blake2b error appears to be a CI Python environment issue (OpenSSL build), not the plugin itself

Thanks for your time!
