SEED is a design system that provides shared visual tokens, styling recipes, and UI components for React, iOS, Android, and Lynx, with Figma integration. It is used to build consistent products across platforms; the catalogue add-ons support agents working with its components, tools, documentation, and development workflows.

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 5.1 | $0.01679 | $0.01679 |
| Opus 5.5 | $0.00672 | $0.00672 |
| Sonnet 5.5 | $0.00336 | $0.00336 |
| Haiku 4.5 | $0.00168 | $0.00168 |
Grade A, and why
seed-design AGENTS.md 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 1mo 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.

SEED Design
디자인 토큰(Rootage)·Recipe(qvism)·CSS·React·Lynx 구현과 문서·Figma·MCP·CLI 도구를 함께 관리하는 Bun 모노레포다.
시작
- 학습 기록 관리 규칙을 읽고, 작업 경로·키워드로 메타데이터를 조회한 뒤 관련 활성 교훈만 읽어 계획에 반영한다.
- 루트부터 대상 경로까지의
AGENTS.md를 모두 읽는다. 하위 문서가 더 좁은 규칙과 검증 명령을 둔다. - 여러 패키지에 걸친 변경이거나 어디서 시작할지 모르면
ARCHITECTURE.md를 읽는다. - 테스트·TypeScript 코드를 쓰거나 의존성·changeset·릴리스를 다루면
TECH.md를 읽는다. - 요청과 직접 관련된 코드·설정·문서만 연다.
검증
변경 경로의 명령만 실행한다. 하위 AGENTS.md에 검증 명령이 있으면 그것을 따른다. 문서·AGENTS.md·Skill처럼 실행 동작이 없는 변경은 내용·링크·형식 검토로 끝낸다.

bun test:all
함정:
- React 테스트는 headless 패키지의
lib/빌드를 import한다. headless를 고쳤거나lib/가 없으면 CI처럼bun utils:build && bun headless:build를 먼저 실행한다. Lynx는bun lynx-headless:build다. - 루트
bun test는**/lynx-react*/**를 제외한다. Lynx 패키지는bun test:lynx-react(typecheck + Vitest)로 돌린다. bun rootage:test의 validator는 미사용 schema property를 지우며 원본 YAML을 다시 쓸 수 있다. 실행 뒤git diff로 의도한 변경만 남았는지 확인한다.
생성
생성물은 직접 고치지 않는다. git check-attr linguist-generated -- <파일>이 set이면 생성물이다. 원천은 .gitattributes이고, 수동 관리 예외는 해당 패키지 AGENTS.md에 있다.
- 원천을 고친다.
- 영향받는 단계만 실행한다.

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.

seed-design AGENTS.md is an instructions file published in the GitHub repository daangn/seed-design (1,181 stars, last pushed today), licensed Apache-2.0. It adds 1,679 tokens to every session, about $0.0067 per session on Opus 5.5. 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 2026-08-31.
