Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00201 | $0.07904 |
| Opus 5 | $0.00101 | $0.03952 |
| Sonnet 5 | $0.00040 | $0.01581 |
| Haiku 4.5 | $0.00020 | $0.00790 |
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.
How it starts
The opening of the file, as written. The whole thing — 711 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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.

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.
- 12d ago First seen · 711 lines · 201 tokens per session scan A 8713bacab61d
orcamento-obra is a skill published in the GitHub repository heliopaivajr/civil-skills (7 stars, last pushed 5mo ago), licensed MIT. It adds 201 tokens to every session and 7,904 once invoked, about $0.0010 per session on Opus 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.
