Web Anatomy — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited Web Anatomy (Plugin) and scored it 91/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 1 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

The primary manifest — the file an agent reads to learn what this artifact does.
Skills for your AI agent that ship landing pages that work. Built from the plays the best SaaS companies actually shipped, grounded in a scored benchmark library so every recommendation cites a real page instead of generic advice.
$ npx skills add GabrielAmz/web-anatomyInstalls the Web Anatomy skill pack for Claude Code, OpenAI Codex, Cursor, Windsurf, and any agent that supports the Agent Skills spec.
Most AI agents rework a page from generic advice: add social proof, make the CTA stronger, tighten the headline. Web Anatomy gives the agent evidence instead. The skills read a page as a structure of known sections (hero, value proposition, trust, testimonial, pricing, FAQ, CTA), then ground every move in a benchmark library of real pages scored section by section.
The benchmark behind the skills (numbers to confirm before release):
The skills run standalone with built-in patterns. Connecting the hosted MCP (highly recommended) pulls the live benchmark data and real reference screenshots into every report. See Live benchmark data.
Web Anatomy works at four zoom levels. The altitude matches the question being asked.
| Altitude | The question | Skill |
|---|---|---|
| Page | What do the strongest pages in this market do, and how does mine compare? | find-examples |
| Audit | How does my whole page stack up, and what should I change first? | audit-page |
| Section | How do I level up one section, from foundational to best-in-class? | research-best-practices |
| Fix | Write the grounded copy to rework a page or build a new one. | write-page |
After the copy is written, `build-page` assembles the structure + copy into a shareable wireframe with a coherent, single-exemplar design system. It is the terminal step on both branches (improve and create), so it sits above the altitudes rather than inside one.
Run webanatomy-setup once first. It captures product, ICP, industry, competitors, and proof assets into .agents/webanatomy-context.md, so every skill gives sharper, on-brand recommendations.
audit-page (diagnose) -> write-page (rewrite the weak sections) -> build-page (optional: assemble the improved page as a shareable wireframe, in your page's own look).find-examples (pick one exemplar homepage) -> write-page build mode (a light outline adopts the exemplar's section order, then writes the copy) -> build-page (assemble the wireframe in the exemplar's look).| Skill | Altitude | What it does |
|---|---|---|
webanatomy-setup | Foundation | Run once. Captures product, ICP, industry, competitors, proof assets, and priority pages into .agents/webanatomy-context.md. |
find-examples | Page | The market scan. Pulls the top-ranked pages and sections in a market, shows what to steal, and when you share your page, labels how it compares. Absorbs the old benchmark-compare. |
audit-page | Audit | Scores the current page against a CRO rubric, diagnoses it section by section, and returns a prioritized fix list. Runs standalone, no MCP required. |
research-best-practices | Section | The section deep-dive. Takes one section and returns a tiered improvement ladder (foundational, competitive, best-in-class), each grounded in real benchmark sections. |
write-page | Fix | The copy engine. Turns a diagnosis, a tier, or a chosen structure into grounded copy-paste sections; reworks an existing page or writes a new one. |
build-page | Assemble | The terminal assembler. Takes a structure + its copy and lays them out as a shareable wireframe with a single-exemplar design system (a benchmark page for a new page, your own page when improving). |
moodboard | Page | The section-by-section visual board. Captures the live page section by section and pulls benchmarks from the MCP, then composes each section as current-state-large + problems + a benchmark screenshot grid + discipline-tagged practices + recommendation. Where find-examples shows what to steal, moodboard composes the whole page as a visual reference you build from. |

The skills work on their own, so install them and start immediately. Connecting the hosted Web Anatomy MCP is never mandatory, but highly recommended: it grounds every recommendation in live benchmark data and real reference examples instead of static guidance, which is where the skills are at their best. It needs a beta token and one config command per IDE:
Sign in at https://www.webanatomy.ai/dashboard/mcp to get your token + per-IDE config. You must be signed in, because the page generates your personal token there.
The skills use MCP tools such as search_pages, get_page, search_sections, and get_section when connected, and degrade gracefully to static guidance when not. Scores, thresholds, raw marker coordinates, and benchmark field names stay internal; user-facing reports translate them into plain-English patterns and gap labels.
Want to see the benchmark first? Browse the public scored sections gallery at https://www.webanatomy.ai/best-landing-pages/sections — real landing-page sections, scored, with what makes each one work. It is the same library the MCP serves to your agent, so you can explore it before connecting anything.
Most AI-agent skill packs frame pages as a job (CRO, copywriting, SEO). Web Anatomy frames them as a structure: hero, proof, problem, solution, pricing, FAQ, CTA. Every section has known patterns, known anti-patterns, and known reference companies.
Every Web Anatomy skill turns a page into parts: hero, proof, problem, solution, pricing, FAQ, CTA. Each part has known patterns, anti-patterns, and benchmark examples. The framework and the evidence travel together.
.agents/skills/<name>/SKILL.md per the Agent Skills specOption 1 — CLI (any agent):
# Installs the whole pack to .agents/skills/
npx skills add GabrielAmz/web-anatomy
# Update later (or just re-run the command above, it's idempotent)
npx skills update GabrielAmz/web-anatomyOption 2 — Claude Code plugin (version-aware updates):
/plugin marketplace add GabrielAmz/web-anatomy
/plugin install web-anatomyClaude Code knows the installed version and when a newer one ships. Update with /plugin marketplace update web-anatomy then /plugin update web-anatomy, or turn on auto-update for the marketplace to make it hands-off. Skills install namespaced: /web-anatomy:write-page, /web-anatomy:build-page, and so on.
Option 3 — clone and copy manually:
git clone https://github.com/GabrielAmz/web-anatomy
cp -r web-anatomy/skills/* .agents/skills/After install, start with webanatomy-setup. The benchmark-backed workflows degrade gracefully when MCP isn't connected, falling back to static/reference guidance, but they are at their best with live benchmark data, so connecting MCP is highly recommended.
