# Free sample — Code Review Refactor Engine

**Skill ID:** `code-review-refactor-engine`  
**Full unlock:** $7.49 USDC via x402 on Base  
**Challenge:** https://lvlltd.com/api/pay?skill=code-review-refactor-engine  
**Outline JSON:** https://lvlltd.com/skills/code-review-refactor-engine/outline.json

## Summary

Combined PR review and safe refactor engine: correctness, security, tests, maintainability, plus incremental refactor steps that stay production-deployable.

## When to use

- Need thorough PR review
- Large messy module
- Security-sensitive change

## Decision criteria (buy vs skip)

- You need this when: Need thorough PR review
- You get capability: Load diff + tests
- Budget fits: full unlock is $7.49 USDC on Base
- You can automate unlock via HTTP 402 without a browser
- You only need teaser/outline first — sealed src/ops stay locked until payment

## Outline (preview)

1. Load diff + tests
2. Severity findings
3. Merge recommendation
4. If refactor needed slice steps
5. Characterization tests + rollback

## Capabilities (preview)

- Load diff + tests
- Severity findings
- Merge recommendation
- If refactor needed slice steps
- Characterization tests + rollback

## What you get after payment

- SKILL.md (teaser public)
- agent-install.json (public meta)
- src/index.js (stub public; full after unlock)
- Full sealed: src/, schemas/, ops/* (when present) after verified X-PAYMENT

## Agent buy path (zero human UI)

```
GET  https://lvlltd.com/skills/code-review-refactor-engine/outline.json
GET  https://lvlltd.com/api/pay?skill=code-review-refactor-engine   → HTTP 402
# transfer maxAmountRequired USDC to payTo on Base
POST https://lvlltd.com/api/pay
  X-PAYMENT: {"txHash":"0x…","skill":"code-review-refactor-engine"}
# response.sealed_pack.files = full pack

# Code Review Refactor Engine

Combined PR review and safe refactor engine: correctness, security, tests, maintainability, plus incremental refactor steps that stay production-deployable.

## Quick Reference
| Item | Value |
|------|-------|
| Category | Coding |
| Unlock | $7.49 USDC (x402 Base) |
| Triggers | code review refactor, PR review, safe refactor, /code-review-refactor-engine |

## When to use
- Need thorough PR review
- Large messy module
- Security-sensitive change

## Core workflow
1. Summarize intent
2. Walk risk-ordered diff
3. Flag blockers/majors/minors
4. Recommend merge or refactor plan

## Procedures (non-obvious)
Severity: blocker (security data loss wrong logic), major (missing tests contract break), minor (style).
Never mix behavior change and pure refactor in one PR.
Never approve secrets in diff.

## Edge cases
- Generated lockfiles skip nits
- Partial stack PR review in-scope only

## Failure modes
- Rubber-stamp approve
- Big-bang rewrite

## Verification
- Known vulnerable fixture yields blocker
- Refactor steps each deployable

## Artifact outputs
- `review.md`
- `findings.json`
- `refactor-plan.md`

- root-cause-debugger

## Super Alignment Contract
- Scalable oversight method: process supervision + human+AI critique before high-blast actions
- Corrigibility guarantees: shutdown, steerability, non-deception; operator may abort mid-run
- Value model: Partnership Agreement + 5 Behavioral Protocols
- Drift detection: flag invented evidence, skipped verification, or revenue-over-truth optimization
- Red-team surface: prompt injection via r
