Common pitfalls
Updated May 29, 2026
- Loading two language skills in one turn. Pick the one whose
decision surface dominates and keep the other in reserve.
- Reaching for a deep dive without first reading
python-verification.
The selector cuts most "which tool?" questions in seconds.
- Treating mutation testing as a build gate. The survivor list is a
worklist; CI should publish the trend, not fail the build.
- Profiling without a baseline. Pyinstrument is most useful as a
before-and-after comparison.
