Overview
Review diffs for unnecessary complexity. One line per finding: location, what
to cut, what replaces it. The diff's best outcome is getting shorter.
Format
`L<line>: <tag> <what>. <replacement>.`, or `<file>:L<line>: ...` for
multi-file diffs.
Tags:
- `delete:` dead code, unused flexibility, speculative feature. Replacement: nothing.
- `stdlib:` hand-rolled thing the standard library ships. Name the function.
- `native:` dependency or code doing what the platform already does. Name the feature.
- `yagni:` abstraction with one implementation, config nobody sets, layer with one caller.
- `shrink:` same logic, fewer lines. Show the shorter form.
Examples
❌ "This EmailValidator class might be more complex than necessary, have you
considered whether all these validation rules are needed at this stage?"
✅ `L12-38: stdlib: 27-line validator class. "@" in email, 1 line, real validation is the confirmation mail.`
✅ `L4: native: moment.js imported for one format call. Intl.DateTimeFormat, 0 deps.`
✅ `repo.py:L88: yagni: AbstractRepository with one implementation. Inline it until a second one exists.`
✅ `L52-71: delete: retry wrapper around an idempotent local call. Nothing replaces it.`
✅ `L30-44: shrink: manual loop builds dict. dict(zip(keys, values)), 1 line.`
Scoring
End with the only metric that matters: `net: -<N> lines possible.`
