Adversarial Verification Agent Pack for Claude Code

The Adversarial Verification Agent Pack gives Claude Code the ability to verify implementations the way a senior engineer would — by trying to break them, not by reading the code and saying "looks good." Based on the verification patterns from Claude Code's internal system prompts.

What You Get

• Full Verifier Agent — 396-line adversarial verification agent with read-only constraint. Strategy matrix for 9 change types (frontend, backend, CLI, infrastructure, database, bug fix, refactoring, mobile, data pipeline). 7 adversarial probe categories. Structured Check/Verdict output. Lists 10 rationalizations to reject.
• Smoke Tester Agent — Lightweight 5-minute quick-check for smaller changes (under 3 files). Build + test + one adversarial probe. Auto-escalates to full verifier if it finds issues.
• /verify Slash Command — Auto-selects smoke tester or full verifier based on change scope.

How to Install

cp agents/*.md .claude/agents/
cp commands/*.md .claude/commands/

Who This Is For

• Developers who want automated adversarial testing before every commit
• Solo developers who lack a code review partner
• Teams building critical systems where bugs are expensive
• Anyone tired of "code looks correct" as verification

The verifier's philosophy: "Your entire value is finding the last 20%. The first 80% is the easy part."
