custo-folha-simulator

custo-folha-simulator is a skill for Claude Code from trycomp-io/comp-skills. It costs 158 tokens per session (1,526 once invoked), scanned A, original, MIT.

A calculator for estimating the total monthly cost of employing people in Brazil, including employer charges, legally required provisions, and benefits. It can use a staff list in CSV format or an employee count and average salary.

In plain words
What is it for?
Use it for payroll budgets, hiring projections, and scenario comparisons. It is not a replacement for a real payroll system.
Why use it?
Salary alone does not show the employer’s full cost, so the calculator includes common charges and provisions in the estimate.

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.

Security

Grade A, and why

custo-folha-simulator 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 9d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (eam_client.py, scripts/custo_folha.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Custo de Folha Simulator

Simula o custo TOTAL empregador da folha brasileira em segundos. Não executa folha (use seu HRIS pra isso): serve pra orçamento, projeção, cenários.

Dual-mode operation (Code + Cowork)

  • Claude Code: python3 scripts/custo_folha.py ... (CSV de roster ou estimate).
  • Claude Cowork: cálculo inline com as taxas abaixo. Modo estimate é nativo; modo CSV grande sugerir Code.

Inline calculation logic (Cowork)

Taxas (Brasil 2024/2025)

Encargos patronais (~35,8%):

  • INSS patronal: 20%
  • FGTS: 8%
  • SAT: 2% (varia 1-3% por CNAE, default 2%)
  • Sistema S + salário-educação + INCRA: 5,8%

Provisões mensais (~19,7%):

  • 13º salário: 8,33% (1/12)
  • Férias: 8,33% (1/12)
  • 1/3 constitucional: 2,78%
  • Multa FGTS rescisória provisionada: ~0,27%/mês

Onerated factor: ~1,555 (salário × 1,555 = custo total mensal, sem benefícios extras)

Modo estimate (Cowork, caso comum)

CHRO informa: headcount + salário médio + (opcional) benefícios médios mensais.

Cálculo:

  1. total_salário = headcount × salário_médio
  2. encargos = total_salário × 0,358
  3. provisões = total_salário × 0,197
  4. benefícios = headcount × (VR/VA + outros)
  5. custo_mensal = total_salário + encargos + provisões + benefícios
  6. custo_anual = custo_mensal × 12

Modo detailed (CSV)

Pra <50 linhas no Cowork: cole o CSV, calcula linha por linha somando. Pra ≥50: usar Code.

Output markdown (Cowork)

## Custo de folha: modo ESTIMATE

**Headcount**: N · **Salário médio**: R$ X

| Componente | Valor mensal |
|---|---|
| Salários brutos | R$ X |
| Encargos patronais (~36%) | R$ X |
| Provisões (~20%) | R$ X |
| Benefícios (VR/VA + outros) | R$ X |
| **Custo mensal total** | **R$ X** |
| **Custo anual total** | **R$ X** |

**Onerated factor**: {factor}x salário

> Não substitui sistema de folha real. SAT varia por CNAE; Sistema S por setor. Pra precisão fiscal use sua folha.

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.
