What is ag-1-construir?

An autonomous software-construction workflow that takes a development objective through stages such as feature work, refactoring, interface changes, issue handling, integration, and optimization.

Use it to turn a requested engineering objective into a pull request, including project-specific checks for user-interface work and dependency installation.

It gives implementation work a defined process with saved state, convergence checks, and self-repair steps.

NVIDIA SkillSpector warn 7 Sept 2026

SkillSpector: 2 findings, up to medium

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

medium MCP Rug Pull · line 38
npx commands without a version suffix (e.g. @1.0.0) create a rug-pull risk if the upstream server is compromised and publishes a malicious update.

Fix: Pin the version: npx @scope/[email protected]
medium Excessive Agency · line 4
Skill selects an external model or provider that may use a different account or billing plan than the operator expects. Undisclosed model switches can cause unexpected cost or quota consumption.

Fix: Remove the model/provider override or disclose it prominently and require explicit operator approval before invoking an external coding CLI or billed model.

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	$0.00056	$0.05484
Opus 5.5	$0.00022	$0.02194
Sonnet 5.5	$0.00011	$0.01097
Haiku 4.5	$0.00006	$0.00548

Measured 2mo ago against content hash f804b5fdd5e9, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

ag-1-construir 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 2mo 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.

CONSTRUIR — Maquina Autonoma de Construcao

Pre-Flight Stack/UI Guard (modo `ui` ou primeira UI no projeto)

Quando ativar:

mode=ui explícito
Projeto novo (< 5 commits) E vai criar componente UI
Primeira vez tocando arquivo .tsx/.css no projeto

Antes de gerar UI, executar Read explícito:

Read ~/Claude/.claude/rules/stack-enforcement.md
Read ~/Claude/assets/design-library/UI_UX/raiz-educacao-design-system.md

Validações inegociáveis:

Tokens Raiz no tailwind.config (#F7941D, #5BB5A2) — NÃO defaults indigo
lucide-react instalado e usado — NUNCA emojis em UI
IBM Plex Sans + Mono via next/font ou Google Fonts
shadcn/ui instalado (npx shadcn@latest init)
Cards usam border-0 shadow-sm (não combinar border + shadow)
Touch targets ≥ 44px
Focus ring 2px solid #F7941D
aria-label em botões de ícone, skip link, aria-current em breadcrumb
Transições 150-300ms transform/opacity + prefers-reduced-motion

Pre-flight para install de deps:

PM verificado: bun.lock → bun, package-lock.json → npm (NUNCA pnpm)
Lib na whitelist? Se não → ADR + perguntar usuário ANTES de instalar
Hook stack-deny-list.sh BLOQUEIA pnpm/yarn/turbo automaticamente

What this file has done since we first saw it
