Core rule
Every finding needs a concrete case showing which input or situation leads to a wrong result; no case, no finding.
Execution Phases
Phase 01Understand first
Read the diff plus callers, called functions, tests and README, trace the data flow, and find the expected load in the repo.
Phase 02Look for problems
Check in order for bugs, security and data-loss risks, scale problems, missing tests, speed, and code that should not exist.
Phase 03Check before reporting
Re-read the lines to confirm each finding, propose the smallest fix and prefer deletions, with no style taste or vague worries.
Phase 04Report in plain English
Start with what the change does, list numbered findings under must fix, should fix and nice to have, and end with a verdict.

Quality review of a change: is the logic right, is it safe, does it hold
under real load, is risky code tested, is it fast enough, and is every line
needed. Reads the connected code, not only the diff. Each finding is
explained in plain English. Use for "review this", "code review", "review
the last commit", "review my PR", "is this over-engineered", /ponytail-review.
