Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00059 | $0.02989 |
| Opus 5.5 | $0.00024 | $0.01196 |
| Sonnet 5.5 | $0.00012 | $0.00598 |
| Haiku 4.5 | $0.00006 | $0.00299 |
Grade A, and why
senior-frontend scanned grade A with 1 finding 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Scaffolding de Projeto
Gere um novo projeto Next.js ou React com TypeScript, Tailwind CSS e configurações de melhores práticas.
Workflow: Criar Novo Projeto Frontend
-
Execute o scaffolder com o nome e template do projeto:
python scripts/frontend_scaffolder.py my-app --template nextjs -
Adicione funcionalidades opcionais (auth, api, forms, testing, storybook):
python scripts/frontend_scaffolder.py dashboard --template nextjs --features auth,api -
Navegue até o projeto e instale as dependências:
cd my-app && npm install -
Inicie o servidor de desenvolvimento:
npm run dev
Opções do Scaffolder
| Opção | Descrição |
|---|---|
--template nextjs |
Next.js 14+ com App Router e Server Components |
--template react |
React + Vite com TypeScript |
--features auth |
Adicionar autenticação NextAuth.js |
--features api |
Adicionar React Query + cliente de API |
--features forms |
Adicionar React Hook Form + validação Zod |
--features testing |
Adicionar Vitest + Testing Library |
--dry-run |
Pré-visualizar arquivos sem criá-los |

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.

senior-frontend is a skill published in the GitHub repository ricneves-ai/flowgrammers-skills (117 stars, last pushed 1mo ago), licensed MIT. It adds 59 tokens to every session and 2,989 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
Other skills, from other repositories
client-setup
Create a vanilla tRPC client with createTRPCClient (), configure link chain with httpBatchLink/httpLink, dynamic headers for auth, transformer on links (not client constructor). Infer types with inferRouterInputs and inferRouterOutputs. AbortController signal support. TRPCClientError typing.
trpc-router
Entry point for all tRPC skills. Decision tree routing by task: initTRPC.create(), t.router(), t.procedure, createTRPCClient, adapters, subscriptions, React Query, Next.js, links, middleware, validators, error handling, caching, FormData.
adapter-express
Mount tRPC as Express middleware with createExpressMiddleware() from @trpc/server/adapters/express. Access Express req/res in createContext via CreateExpressContextOptions. Mount at a path prefix like app.use('/trpc', ...). Avoid global express.json() conflicting with tRPC body parsing for FormData.
custom-features
Implement a Table v9 plugin when built-ins and typed meta are insufficient. Covers FeatureMaps, runtime lifecycle hooks, prototypes, and a complete checked example.
fast-typescript-check
Keep www-sacred's TypeScript fast to type-check and fast to run. Use when touching the ASCII/canvas animation components (the only real per-frame code here), tightening type-check wall-clock, or auditing a change for runtime or compiler regressions. Scoped to this repo — a React 19 / Next.js 16 component library plus…
port-sacred-terminal-ui-to-typescript-cli
Take a React Window.tsx (or any sacred component) and produce a terminal CLI screen written in TypeScript that uses Simulacrum — the sacred CLI framework in scripts/cli/lib/.
