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 | $0.00075 | $0.01681 |
| Opus 5.5 | $0.00030 | $0.00672 |
| Sonnet 5.5 | $0.00015 | $0.00336 |
| Haiku 4.5 | $0.00007 | $0.00168 |
Grade A, and why
scaffold-frontend 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.
How it starts
The opening of the file, as written. The whole thing — 165 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Scaffold Frontend
This skill creates the frontend for the user's project inside a clients/ directory at the repo root. The app is driven by the existing PRD.md and AGENTS.md. Every page, every navigation link, and every data type is derived from those two files.
Preflight: PRD and AGENTS Must Exist
Before doing anything else, check that both files exist at the repo root:
test -f AGENTS.md && test -f PRD.md && echo OK || echo MISSING
If either file is missing, STOP and respond exactly:
This skill cannot run yet.
AGENTS.mdandPRD.mdmust exist at the repo root before scaffolding the frontend. Run thedomain-to-specskill first, or run thequickstartskill to chain everything automatically.
Do not create any files. Do not ask clarifying questions. Just direct the user to domain-to-spec.
Step 1: Read the PRD and AGENTS
Read PRD.md and AGENTS.md end-to-end. Extract:
- Project name and one-sentence summary (from
PRD.md > What Is This?) - Pages list (from
PRD.md > Pages / Screenstable). You will generate one route per row. - User flow (from
PRD.md > User Flow). Used to order the pages and decide navigation. - Core features (from
PRD.md > Core Features (MVP)). Used to decide the primary CTA on the landing page. - Data model (from
PRD.md > Data Model). Used to create TypeScript interfaces inclients/types/. - Backend Needed? (from
PRD.md > Backend Needed?). If Yes, createclients/lib/api.tswith a fetch wrapper pointed atNEXT_PUBLIC_API_URL. If No, skip that file. - Tech stack and code style (from
AGENTS.md). Match the conventions it declares.
Step 2: Scaffold clients/
Run these commands from the repo root:
pnpm create next-app@latest clients --typescript --tailwind --app --eslint --src-dir=false --import-alias="@/*" --turbopack --no-install
cd clients && pnpm install
Notes:
- The scaffold goes into
clients/at the repo root, NOT a sibling of the repo. - If
clients/already exists and is non-empty, STOP and ask the user whether to overwrite, merge, or skip. Never overwrite silently.
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.

scaffold-frontend is a skill published in the GitHub repository emilyLi2020/WAVE (2 stars, last pushed 4mo ago), licensed Apache-2.0. It adds 75 tokens to every session and 1,681 once invoked, about $0.0003 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.
