What is html-to-block-theme?

A converter that turns static HTML, CSS, and JavaScript files into a WordPress block theme on a local Studio site. WordPress block themes use editable blocks, templates, and settings to manage a site’s design and content.

Use it to create a theme with theme settings, reusable design sections, custom blocks, and browser-based visual refinement.

It removes the need to recreate a static design manually in WordPress while keeping the result editable through WordPress.

Security

Grade A, and why

html-to-block-theme 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 6d 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.

Contents

What it installs

The manifest is a name and a version. 2 skills, 2 agents travel with it, and installing the plugin installs all of them — 491 tokens a session between them. Each is measured on its own page, and each can be installed alone.

Changes

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.
