orcamento-obra

orcamento-obra is a skill for Claude Code, Codex from heliopaivajr/civil-skills. It costs 201 tokens per session (7,904 once invoked), scanned A, original, MIT.

A construction-cost estimating guide for producing detailed budgets for building, renovation, and civil-engineering work. It can structure quantities, unit costs, totals, indirect costs, and profit using references such as SINAPI, TCPO, custom market prices, or BIM classifications.

In plain words
What is it for?
Use it to prepare work budgets, quantity takeoffs, unit-price compositions, BDI calculations, cost spreadsheets, and ABC curves, which rank items by their share of total cost.
Why use it?
It turns a project description and measured quantities into a traceable cost spreadsheet, helping avoid incomplete estimates and unclear pricing assumptions.

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

orcamento-obra 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 12d 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.

Orçamento de Obra — Construção Civil

Visão Geral

Esta skill transforma o agente em um orçamentista sênior de obras, dominando múltiplas bases de referência de custos — SINAPI, TCPO, composição própria de mercado e estruturação BIM (ABNT NBR 15965) — além de BDI, composições de preços unitários (CPU), curva ABC e legislação vigente (Lei 14.133/2021 e Decreto 7.983/2013).

O orçamento produzido segue o padrão analítico — o mais preciso e exigido em obras públicas e privadas de médio/grande porte — estruturado em macroetapas, etapas e serviços com código de referência, descrição, unidade, quantidade, custo unitário e custo total.

A base de referência é escolhida pelo usuário na Etapa 0, e toda a estrutura subsequente se adapta automaticamente à escolha feita.


Quando Usar Esta Skill

Acione automaticamente quando o usuário mencionar:

  • Orçar / orçamento / orçamentação de obra, serviço, reforma ou construção
  • Planilha orçamentária / planilha de custos / planilha de quantitativos
  • SINAPI / TCPO / composição de preços / CPU / custo unitário
  • BDI / taxa de administração / lucro / custo indireto
  • Levantamento de quantitativos / levantamento de serviços
  • Curva ABC de insumos ou serviços
  • Desoneração / encargos sociais / mão de obra
  • Custo m² de construção / custo global de obra
  • Cotação de insumos / pesquisa de preços
  • Orçamento BIM / classificação ABNT NBR 15965 / Uniclass / Omniclass
  • Orçamento paramétrico / estimativa de custo por sistema

Não acionar quando:

  • O usuário pedir cronograma físico-financeiro → use cronograma-obra
  • O usuário pedir memorial descritivo → use memorial-descritivo-obra
  • Perguntas conceituais gerais sem intenção de produzir documento

Etapa 0 — Seleção da Base de Referência

Esta é a primeira pergunta a fazer. A escolha da base define códigos, formato de planilha, nível de detalhe e compatibilidade legal do orçamento.

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.
