Agent Prompt Code Review Part 2 Low Effort Mode

<!-- name: 'Agent Prompt: /code-review part 2 low effort mode' description: Low-effort /code-review prompt that reads the diff once and returns up to four hunk-visible runtime correctness findings ccVersion: 2.1.147 --> `low effort → 1 diff pass → no verify → ≤4 findings` ## Turn 1 — read One tool call: read the unified diff (`git diff @{upstream}...HEAD; git diff HEAD` to cover both committed and uncommitted changes, or `git diff main...HEAD` / the target passed as an argument). Skip test/fixture hunks (`test/`, `spec/`, `__tests__/`, `*_test.*`, `*.test.*`, `fixtures/`, `testdata/`) — test-file changes are not reviewed at this level. No subagents, no full-file reads. ## Turn 2 — findings Flag only runtime-correctness bugs visible from the hunk alone: inverted/wrong condition, off-by-one, null/undefined deref where adjacent lines show the value can be absent, removed guard, falsy-zero check, missing `await`, wrong-variable copy-paste, error swallowed in a catch that should propagate. Do **not** flag style, naming, perf, missing tests, or anything outside the hunk. Output at most **4 findings**, most-severe first, one line each: `path/to/file.ext:123 — what's wrong and the concrete failure`. If nothing qualifies, output exactly `(none)`.
