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.
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 5.1 | $0.00051 | $0.00599 |
| Opus 5.5 | $0.00020 | $0.00240 |
| Sonnet 5.5 | $0.00010 | $0.00120 |
| Haiku 4.5 | $0.00005 | $0.00060 |
Grade A, and why
seed-change 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 24d 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
SEED 변경
요청 결과로 분기 하나를 고른다. 명시가 없으면 계획만이다. 한 분기의 실행이나 승인은 다음 분기의 실행 권한이 아니며, 계획 결과나 변경 파일만을 근거로 다음 분기로 넘어가지 않는다.
| 분기 | 입력 | 결과 | 승인·중단 경계 | 절차 |
|---|---|---|---|---|
| 계획만 | 현재 checkout, 실제 분기 기준 --base-ref, 확정된 --lane·--bump·--no-release |
영향 패키지·표면, 검증 순서, targetBranch·targetRef·prBase |
읽기 전용. Git 상태·파일·원격을 바꾸지 않는다. 브랜치 값이 unknown이면 제출 불가다. |
impact-plan.md |
| changeset | 기준 브랜치, 공개 패키지 후보 | 패키지별 bump·근거, 한국어 초안, 승인 뒤 .changeset/*.md |
후보 분석은 읽기 전용. 현재 요청에서 bump·문안이 확정되지 않았으면 승인 뒤에만 파일을 쓴다. dependency range는 수정하지 않는다. | changeset.md |
| 제출 | 명시적 제출 요청, 확정한 계획의 targetRef·prBase |
rebase된 feature 브랜치, commit, push, PR base | 포함 파일·commit, push, PR 생성·base 변경을 각각 현재 요청의 승인 범위에서 확인한다. unknown, 기준·원격 SHA 변화에서 중단한다. |
submit.md |
두 CLI는 저장소 루트에서 Bun으로 직접 실행하고 JSON을 출력한다.
bun skills/seed-change/scripts/change-plan.ts --base-ref origin/dev
bun skills/seed-change/scripts/changeset-plan.ts --base-ref origin/dev
제출에는 실행 스크립트가 없다. rebase·push·PR 명령은 submit.md의 확인 순서대로 직접 실행한다.
What ships with it
7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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-change is a skill published in the GitHub repository daangn/seed-design (1,180 stars, last pushed today), licensed Apache-2.0. It adds 51 tokens to every session and 599 once invoked, about $0.0002 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 2026-09-23.
