Independent Reviewer & Scope-Creep Detector System Prompt Kit

Two system prompts for running a genuine second-opinion reviewer persona on AI-agent-written code — for developers on Claude Code, Cursor, Windsurf, or Copilot who want a real independent check before merging, not a self-review from the same context that wrote the code.

Description

The model that writes a change is the worst-positioned model to review it — it already believes its own assumptions and scope decisions were reasonable. This kit gives you a portable, tool-agnostic reviewer persona that runs a structured six-failure-mode pass (silent assumptions, scope creep, instruction drift, unrelated-code touches, verification gaps, bad handoffs) against a diff and the original task, plus a lighter scope-only prompt for fast mid-task checks. Includes real setup instructions for wiring both into a Claude Code subagent, a Cursor Custom Mode, a Windsurf rule, or a Copilot workflow, a companion verification-gate checklist, and a full worked example showing exactly what a real finding looks like.

What's included

  • system-prompts/independent-reviewer.md — the full six-failure-mode review persona, with output format and usage rules
  • system-prompts/scope-creep-detector.md — a lighter, faster scope-only check for mid-task use
  • system-prompts/verification-gate-checklist.md — the human-side checklist to run alongside the two prompts
  • setup/claude-code-subagent.md — real .claude/agents/ subagent wiring with recommended tool permissions
  • setup/cursor-custom-mode.md — Cursor Custom Mode setup plus a fallback for plans without it
  • setup/windsurf-cascade.md — Windsurf rule scoping and fresh-conversation invocation
  • setup/copilot-instructions.md — Copilot-specific setup including a PR-review-based approach
  • examples/example-flagged-review.md — a full worked example: a flawed diff and the exact structured findings against it
  • README.md — quick start and what this is/isn't
