VP of Engineering advisory: delivery throughput analyzer (DORA 4 metrics + cycle-time bottleneck identification), eng hiring funnel calculator (7-stage conversion + pipeline gap + weakest-stage fixes), eng team structure designer (squad/tribe model + manager-trigger + director-trigger + span-of-control). 4 in-depth references: DORA framework, eng hiring funnel, eng team structure (Conway's Law), production discipline (on-call, incidents, deployment, SLOs). Stdlib-only. Standalone-installable; also bundled in c-level-skills. NOT a CTO skill — VPE owns how the team ships, CTO owns what to build.

Hypothesis testing, A/B experiment analysis, sample size calculation, and confidence intervals. 3 stdlib-only Python tools with Z-test, t-test, chi-square, effect sizes, power analysis, and Wilson score intervals.

Premium single-file HTML landing page generator with GSAP 3D animations, scroll-triggered effects, and mouse-parallax depth. Forcing 3-4 question grill-me intake (product+pitch, audience register, brand overrides, tone) locks down positioning before any copy or markup is written. Outputs a single self-contained HTML file (Claude Code) or HTML artifact (Claude.ai) with all CSS/JS inline — only externals are Google Fonts + GSAP via CDN. Configurable brand colors via CSS custom property overrides. Source spec: megaprompts/04-landing-megaprompt.md (PR #657). Distinct from product-team/skills/landing-page-generator (which outputs Next.js TSX for conversion-optimized lead-gen) — this skill is for premium visual one-pagers with motion design.

Arquiteto de Empresa (PT-BR): constrói um negócio do zero como um bundle OKF (Open Knowledge Format) — uma árvore de arquivos .md versionáveis com frontmatter type, links formando grafo, e index.md/log.md reservados, legível por humanos e por agentes. Conduz o fundador por uma entrevista de 12 fases (fundação, estratégia, mercado, financeiro, comercial, marketing, produto, operações, tech, pessoas, jurídico, governança), uma fase por vez, e gera os conceitos markdown conformantes. 3 ferramentas stdlib: scaffold_bundle (andaime do bundle), okf_linter (valida type/arquivos reservados/links), index_generator (regenera os index.md). Standalone-installable; também empacotado em c-level-skills.

A disciplined coding pipeline that grounds code in verified structure before a line is written: Discuss -> Map -> Decompose -> Execute -> Verify, with a lazy-senior-dev YAGNI ladder that deletes unnecessary code first. No invented APIs, no assumed imports, no placeholder code. Opt-in for high-stakes, complex, or multi-file work; not for trivial edits. Synthesizes four MIT/open-source projects (Ralph, GSD Core, Graphify, Ponytail).
