What is financas-app?

A backend guide for generating downloadable PDF and CSV files from Node and Express endpoints and testing the actual file data.

It is for PDF reports, CSV downloads, streamed responses, currency formatting, and Jest or Supertest checks of exported bytes.

It helps avoid exports that return a successful response but contain invalid, incomplete, or incorrectly formatted files.

Per session 125 Skills are progressive disclosure: only the name and description are preloaded; the body loads when the skill is used.

When invoked 2,126 The whole file, excluding the scripts and references it only reads on demand.

Origin original No closer match found in the catalogue.

Token cost

What it costs to keep this loaded

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	$0.00125	$0.02126
Opus 5	$0.00063	$0.01063
Sonnet 5	$0.00025	$0.00425
Haiku 4.5	$0.00013	$0.00213

Measured 7d ago against content hash c7d34f868eb6, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-11, from the pricing page.

Security

Grade A, and why

financas-app 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 7d 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.

Makes network callslowCapability

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

financas-app — correção e extensão

App de controle financeiro (Node 20 + Express, EJS SSR + JS vanilla, MongoDB/Mongoose, Zod, JWT). Três módulos independentes (financas/investimentos/veiculos) ligados por flags em config/env.js. Arquitetura de camadas rígida: rota → controller → service → model. Seguir AGENTS.md (Zod obrigatório, erros com AppError, sem JS inline — todo script em /js/, CSP proíbe unsafe-inline).

Arquitetura de deploy (PORTA ÚNICA 4460)

:4460 (nginx, única porta exposta)
   /demo/*  ──► app-demo  (autologin, mongo-demo isolado, JWT_SECRET_DEMO)
   /*       ──► app       (principal; mongo volume fa_mongo_data)

app-demo monta rotas TAMBÉM sob /demo (páginas /demo/* e APIs /demo/api/*); o frontend prefixa chamadas de API com data-api-prefix do <html> (lido em common.js).
demoAutologin emite JWT de verdade a cada request (só com DEMO_AUTOLOGIN=true).

PITFALL RECORRENTE (já custou horas)

A página /demo/app carrega o CSS de /css/main.css (app principal), NÃO de /demo/css/main.css (app-demo). Por isso, para validar qualquer correção de CSS, é obrigatório rebuildar AMBOS os containers (app e app-demo) e subir com a mesma ASSET_VERSION. Se mexer só no app-demo, o CSS novo não aparece no browser.

Bump ASSET_VERSION via env no shell (não editar .env): ASSET_VERSION=N docker compose -p fa build --no-cache app app-demo && docker compose -p fa up -d app app-demo.
Se o CSS servido não mudar, o Docker pode ter cacheado a camada de COPY: usar --no-cache.
Checar o CSS servido: curl -s http://127.0.0.1:4460/css/main.css | grep ... (app principal) e /demo/css/main.css (app-demo).

Validação no browser (headless)

O browser da ferramenta alcança o docker no host 192.168.80.1:4460 (NÃO 127.0.0.1:4460).
browser_navigate + browser_snapshot para inspecionar; browser_vision para checagem visual (tema claro/escuro). O usuário aprova UI só vendo screenshot real.
browser_click nem sempre dispara handlers JS (overlay/datepicker interceptando); se o modal não abrir, disparar via browser_console: document.querySelector('button[data-acao=...]').click().
Evitar cache do browser de validação: ao trocar ASSET_VERSION, navegar primeiro na URL exata do CSS (/css/main.css?v=N sem /demo) para popular aquele cache, depois na página.

What ships with it

5 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.

Changes

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.
