Frisk your diff for new logic that ships with no test touching it. Triggers automatically when you are about to report a coding task done and your diff added or changed a function or a branch (or on /testfrisk). Coverage percentage is a lie of averages — it can be 90% while the exact if you just added is the untested 10%. testfrisk reads the changed lines, finds the new branches and behaviors, checks whether any test actually exercises each one, and refuses to say "done" while a new code path ships with zero test hitting it.
