• nosprintfhostport: Checks for misuse of Sprintf to construct a host with port in a URL. [fast: true, auto-fix: false]
• reassign: Checks that package variables are not reassigned [fast: false, auto-fix: false]

Thanks for the contribution @Prajyot-Parab 😃

IMO it would be better not to include execinquery and decorder in this PR, but it would be great to see a discussion in a new PR about how to implement the rules in decorder in CAPI.

It would be awesome if you could enable a pattern in the settings for reassign and fix the findings in this PR though!

I agree with @killianmuldoon summary.

@Prajyot-Parab Thank you for your help. There are some good checks here that we are missing.

[oscr]
