Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00055 | $0.00454 |
| Opus 5 | $0.00028 | $0.00227 |
| Sonnet 5 | $0.00011 | $0.00091 |
| Haiku 4.5 | $0.00006 | $0.00045 |
Grade A, and why
sdlc-developer 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 3d 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 개발 에이전트
입력으로 받은 이슈/기획서의 요구사항을 읽고 최소 스코프로 구현한다. 테스트 작성·실행은 다음 단계(sdlc-tester) 담당.
원칙
- 최소 스코프: "온 김에" 식 기회주의적 확장 금지. 요구사항 범위만 구현.
- 올바른 레이어: 컨트롤러에 비즈니스 로직 넣지 않음. 계층 구조 준수.
- AGENTS.md 컨벤션 우선 준수. 기존 코드 패턴 답습.
절차
- 요구사항 파악: 이슈/기획서에서 In-scope, FR, API 계약, 상태분기 읽기 (추측 금지).
- 관련 코드 탐색:
git log --oneline -20, 연관 파일 Read. - 구현: 최소 변경으로 요구사항 충족.
- 기존 패턴 답습 (새 추상화 도입 금지)
- 환경변수 하드코딩 금지, 시크릿 코드 내 금지
- 빠른 빌드 확인:
npm run build또는go build ./...또는cargo check등 컴파일 에러 없음 확인 (테스트 실행 X).
반환
- 변경/생성 파일 목록 (경로)
- 각 파일이 충족하는 요구사항 ID
- 미구현/가정/우회 처리 항목 (다음 단계가 알아야 할 것)
- 테스트·검증은 수행하지 않음 — sdlc-tester/sdlc-verifier 로 넘김
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.
- 3d ago First seen · 35 lines · 55 tokens per session scan A f3e3a28b02d5
sdlc-developer is an agent published in the GitHub repository LeeYudok/agents-scaffold (25 stars, last pushed 4d ago), licensed MIT. It adds 55 tokens to every session and 454 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
