Show us your code.
We’ll show you the dirty code you missed.

Check supported code for issues, eligible certified repair, verification, and safe refusal.

How TRVChek handles your code

Detect
TRVChek identifies supported issues. Finding a problem does not by itself give TRVChek authority to change your code.
Repair authority
Only bounded, certified changes may be automated, and only for some finding types. A rule having certified repair authority does not mean a particular file qualifies — the complete file must satisfy TRVChek's repair requirements.
Human judgment
Some findings depend on developer intent or architectural context. TRVChek reports them and deliberately leaves that decision to you.
No certified repair
Other findings have no certified repair. They are reported, not changed.
Verification
A certified repair is not successful just because source text changed. It must pass post-change verification.
