Genshijin Review (Ultra-Terse PR Review)

Forces every code review comment into one line — location, problem, fix — ready to paste into a pull request.

Dev & CodingBeginner★ 330⑂ 14AI score 9/10Last updated: Oct 11, 2026

What it does

  • Enforces a one-line-per-issue comment format: L42: 🔴 bug: cause. Fix.
  • Adds severity prefixes — 🔴 bug (broken), 🟡 risk (works but fragile), 🔵 nit (style, author may ignore), ❓ question.
  • Strips hedging ("it seems", "you might consider") and redundant explanations of what the diff already shows.
  • Keeps exact line numbers, backticked symbol names, and concrete fixes (no vague "consider refactoring").
  • Automatically switches back to full prose for security findings, architectural disagreements, and onboarding contexts.
  • Review-only scope: it won't edit code, approve/request changes, or run linters.

Who it's for

  • Tech leads and senior engineers who spend too long writing review comments
  • Teams whose review cycles drag due to verbose feedback
  • Anyone who wants comments that paste cleanly into GitHub/GitLab

Examples

  1. "Review this PR" → L42: 🔴 bug: user can be null after .find(). Guard before .email.
  2. A bloated function → L88-140: 🔵 nit: 50-line fn, 4 responsibilities. Extract validate/normalize/persist.
  3. Unprotected API call → L23: 🟡 risk: no retry on 429. Wrap in withBackoff(3).
  4. Say "normal mode" to disable the terse style.
