rn-harness-contract

rn-harness-contract is a skill for Claude Code from tjdrhs90/rn-launch-harness. It costs 22 tokens per session (1,144 once invoked), scanned A, original, MIT.

A planning step that defines the tests and expected results an app must satisfy before development begins. It lets the app builder and checker agree on clear completion criteria, such as what should happen after a user signs up.

In plain words
What is it for?
Use it to turn a product plan and design into a checklist of verifiable behaviors for screens, user actions, saved data, and error handling.
Why use it?
It prevents vague requirements from being discovered only after the app has been built. Each criterion describes an action, the expected result, and how the result will be checked.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

rn-harness-contract scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

rn-harness-contract — Phase 4: 계약 협상

Generator와 Evaluator가 빌드 전 완료 기준에 합의한다.

Trigger

오케스트레이터에서 Phase 4로 호출됨.

Input

  • docs/harness/plans/YYYY-MM-DD-prd.md (PRD)
  • docs/harness/plans/YYYY-MM-DD-design.md (디자인)
  • docs/harness/specs/YYYY-MM-DD-research.md (시장 조사)

Process

Step 1: Generator가 계약안 작성

PRD의 유저 스토리와 디자인 스펙을 기반으로 15~30개의 검증 가능한 기준을 작성:

## Contract Proposal

### 1. 회원가입
- **Test**: 이메일/비밀번호 입력 → 가입 버튼 탭
- **Expected**: 유효성 검사 통과 → 홈 화면 이동 → 유저 데이터 저장
- **Evidence**: typecheck pass + 코드 확인
- **Type**: code

### 2. 로그인 후 홈 피드
- **Test**: 로그인 → 홈 탭 → 데이터 로드
- **Expected**: 로딩 스피너 → 데이터 표시 → 스크롤 가능
- **Evidence**: typecheck pass + 코드 확인
- **Type**: code

### 3. 프로필 수정
- **Test**: 프로필 화면 → 이름 수정 → 저장
- **Expected**: 수정 후 반영, 에러 시 Toast 표시
- **Evidence**: typecheck pass + 코드 확인
- **Type**: code

Step 2: Review (mode-dependent)

Default mode (1-pass):

  • Generator writes the contract with mandatory criteria included
  • Self-review for completeness and specificity
  • Mark as AGREED immediately
  • Saves tokens by skipping multi-round negotiation

Strict mode (--strict):

  • Evaluator reviews each criterion (specific enough? verifiable? edge cases?)
  • Generator revises based on feedback
  • Iterate until ## Review section says "AGREED"

필수 기준 (MANDATORY)

모든 계약에 반드시 포함:

Anti-Stub 기준
  • AS-1: 핵심 기능이 실제 동작 (setTimeout/mock 아님)
  • AS-2: 엔드투엔드 데이터 흐름 (생성 → 저장 → 새로고침 → 존재 확인)
  • AS-3: 에러 핸들링 (잘못된 입력 시 적절한 에러 표시)
테스트 기준
  • T-1: 테스트 러너 설치 (npm test exit 0)
  • T-2: 핵심 비즈니스 로직 유닛 테스트 존재
코드 품질 기준
  • CQ-1: npm run typecheck 에러 0개
  • CQ-2: npm run lint 에러 0개
  • CQ-3: any 타입 사용 0개
FSD 아키텍처 기준
  • FSD-1: 레이어 계층 준수 (app → widgets → features → entities → shared)
  • FSD-2: 동일 레이어 간 직접 참조 없음
  • FSD-3: barrel export (index.ts) 완전성
모바일 UX 기준
  • UX-1: 모든 화면 SafeAreaView 사용
  • UX-2: 로딩/에러/빈 상태 처리
  • UX-3: 터치 타겟 44x44 이상
  • UX-4: NativeWind className만 사용 (inline style 금지)
