@Premshaw23 Hi! I could use your help with this. This PR only removes obsolete pr_desc*.md files, so it doesn't modify any dependencies or application code.

I noticed the CI is failing during npm ci. While investigating, I found that package.json includes nodemailer, but package-lock.json doesn't seem to be in sync, which causes the installation to fail before the build starts.

Could you please help me figure out if this is an existing issue on the master branch or if there's something I'm missing on my end? Thanks!

Hi @Premshaw23, just following up on this PR whenever you have a chance. Since it only removes obsolete pr_desc*.md files and doesn't affect any application code, could you please take a look when you're available? Thanks!
