NullToHero — Cowork Plugin

v1.9.0 · 4 skills · 53 commands · 83 reference docs · 13 parallel audit sub-agents (SEO + defects + design) · whole-site /audit orchestrator · interactive live variant mode · stack-aware design-system generator · report export · deterministic anti-pattern detector

From zero knowledge to hero website. NullToHero gives Claude a complete design, SEO and motion engineering vocabulary so anyone, even with no prior experience, can build websites that look professional, rank on Google, and pass accessibility audits.

NullToHero exposes four user-invocable skills. Claude Code namespaces plugin skills under the plugin name, so the fully-qualified commands are /null-to-hero:siteasy, /null-to-hero:seo, /null-to-hero:inspect and /null-to-hero:audit. The short forms /siteasy, /seo, /inspect and /audit also resolve as long as no other installed skill claims the same name; prefer the namespaced form if you run several plugins. Each skill routes to its sub-commands through the first argument (for example /seo audit or /siteasy build). The 53 commands listed below are these sub-commands, not separate Claude Code command files: the skills handle routing, so there is no commands/ directory.

Install via marketplace

This repo is also a Claude Code marketplace.

A. As a marketplace (recommended, supports auto-update)

/plugin marketplace add MariusYvard/NullToHero
/plugin install null-to-hero@null-to-hero-marketplace

Future releases pull automatically with /plugin marketplace update null-to-hero-marketplace.

B. Manual install (Unix/macOS/Linux)

git clone https://github.com/MariusYvard/NullToHero.git
bash NullToHero/install.sh

The one-liner bash <(curl -fsSL https://raw.githubusercontent.com/MariusYvard/NullToHero/main/install.sh) also works, but it executes a remote script directly. Clone and read install.sh first if you prefer to inspect it before running.

C. Manual install (Windows PowerShell)

git clone https://github.com/MariusYvard/NullToHero.git
powershell -ExecutionPolicy Bypass -File NullToHero/install.ps1

What's new in 1.9.0

13 parallel audit sub-agents

The five SEO agents are joined by four /inspect defect specialists (inspect-agent-a11y, inspect-agent-interaction, inspect-agent-layout, inspect-agent-code) and four /siteasy design-quality specialists (siteasy-agent-ux, siteasy-agent-visual, siteasy-agent-motion, siteasy-agent-content). /siteasy audit and /inspect review dispatch their agents in parallel, with an inline fallback when the Task tool is unavailable. The SEO agent files are renamed to the seo-agent-* convention so filenames match their dispatch names.

New /audit skill

/audit [url] runs the whole-site audit: one shared fetch phase, all 13 sub-agents in parallel, one merged report (SITE-AUDIT-REPORT.md) and a prioritized ACTION-PLAN.md. Sub-modes seo, defects, design and quick scope the run to one agent group or a fast triage; report formats the result for clients.

Correctness pass

Reconciled the font, imagery and motion contradictions between references; corrected the SEO cross-skill tables; repaired six malformed design-system CSV rows; attributed the MIT design-system component in NOTICE and ATTRIBUTION.md. Validator at 319 checks (audit skill, agent tools field, CSV column integrity).

What's new in 1.8.2

Correctness pass

Aligned the FAQ rich-results status across the SEO references. references/page.md and references/competitor-pages.md still described FAQ as "restricted to government and healthcare sites"; both now match references/schema.md, which records that Google removed FAQ rich results for all sites on May 7, 2026 (FAQPage stays a valid Schema.org type that Google still parses). Added a re-verification note to the schema.md status table so dated retirements get checked before they are quoted.

Documentation and policy

The README now states the plugin-namespaced command form (/null-to-hero:seo) and explains that the short form depends on there being no name collision. SECURITY.md lists 1.8.x as the supported line.

Validator at 261 checks

Check 20 is a regression guard: it fails if any SEO reference reintroduces a present-tense "FAQ restricted to gov/health" claim, while leaving the historical "previously restricted" note in schema.md untouched.

What's new in 1.8.1

Correctness and consistency pass
