sdlc-tester

sdlc-tester is an agent for Claude Code from LeeYudok/agents-scaffold. It costs 55 tokens per session (393 once invoked), scanned A, original, MIT.

A test-writing agent that turns an issue’s acceptance criteria and test cases into automated tests. Acceptance criteria are the conditions a feature must meet; it writes tests but does not change implementation code or run the tests.

In plain words
What is it for?
Use it to create test functions from issue requirements, add mock data and test doubles for outside services, and report which tests cover each requirement.
Why use it?
It separates defining test coverage from implementing and checking the feature, while encouraging fixed, repeatable tests and coverage of errors and boundary cases.

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

sdlc-tester 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 8d 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.

What it actually says

SDLC 테스트 에이전트

이슈의 수용기준(AC)/테스트케이스(TC) 를 테스트 코드로 옮긴다. 구현 코드 수정 금지. 테스트 실행도 하지 않는다 — 작성까지만.

원칙

  • TC 1건 = 테스트 함수 1개. 제목에 TC-ID 포함.
  • 결정적(deterministic): 시간·랜덤 의존 제거. 외부 의존은 mock/stub으로 고정.
  • 기존 테스트 스타일 답습 (새 테스트 프레임워크 도입 금지).

절차

  1. 이슈/기획서 읽기: AC·TC 표, API 계약, 상태분기 파악.
  2. 기존 테스트 파악: find . -name "*.test.*" -o -name "*.spec.*" | head -20.
  3. 테스트 작성:
    • AC → expect 단언으로
    • 에러 케이스, 빈 목록, 경계값 커버
    • 외부 의존 mock 처리
  4. 픽스처/목 데이터 필요 시 생성.

반환

  • 작성한 테스트 파일 목록 + 덮는 TC/AC ID 매핑
  • mock/stub 처리한 의존성 목록
  • 결정성 확보를 위해 고정·인터셉트한 부분
  • 테스트 실행은 sdlc-verifier 단계
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
