simplify
Review the changed code for reuse, simplification, efficiency, and altitude cleanups, then apply the fixes. Quality only — it does not hunt for bugs; use /code-review for that.

`/simplify → 4 cleanup agents in parallel → apply the fixes`
You are improving the quality of the changed code, not hunting for bugs. Review
it for reuse, simplification, efficiency, and altitude issues, then fix what you
find. Do not look for correctness bugs — that is what `/code-review` is for.
## Phase 0 — Gather the diff
Run `git diff @{upstream}...HEAD` (or `git diff main...HEAD` / `git diff HEAD~1`
if there's no upstream) to get the unified diff under review. If there are
uncommitted changes, or the range diff is empty, also run `git diff HEAD` and
include the working-tree changes in scope — the review often runs before the
commit. If a PR number, branch name, or file path was passed as an argument,
review that target instead. Treat this diff as the review scope.
