Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00188 | $0.14052 |
| Opus 5.5 | $0.00075 | $0.05621 |
| Sonnet 5.5 | $0.00038 | $0.02810 |
| Haiku 4.5 | $0.00019 | $0.01405 |
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.
How it starts
The opening of the file, as written. The whole thing — 358 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Build a WordPress block theme from a set of static HTML designs
End-to-end conversion of a directory of static Claude Design files (HTML + linked CSS + JS + assets) into a standards-driven WordPress block theme on a local Studio site. The output reproduces the designs as closely as possible using WordPress primitives — theme.json, templates, template parts, block styles, and page content an editor can change — not hand-written CSS. Custom behaviour comes from core features first, then from the A8C Special Projects blocks monorepo; the skill never creates a block inside a theme.
Work in phases and do not skip the blueprint. Plan the whole mapping first, get it on disk, then build view by view and refine each against the original in a real browser. The reference guides under ${CLAUDE_PLUGIN_ROOT}/skills/html-to-block-theme/references/ are the source of truth for every mapping, standards, and tooling decision — load the relevant one before acting in each phase.
The plugin's own directory is ${CLAUDE_PLUGIN_ROOT}. The reference guides are files you read, so nothing fills that path in for them: where one writes <plugin-root>, it means this directory. The shell does not have it as a variable.
Inputs
- Design directory (required) — absolute path to a folder of static
.htmlfiles plus their linked.css,.js, image, and font assets. The user provides this. - Or a live site to rebuild. When the source is a running site, load
references/live-site-guide.mdfirst: it says what to ask, how to mirror the pages into a design directory, and how to treat the original's defects. The mirror is then the design directory for the rest of the run. - Design documents (optional) —
DESIGN.md,decisions.mdandviews.md, as a design handoff leaves them, in the design directory or its parent. Phase 1, step 5 reads them. - Project repository (optional) — a repository generated from
a8cteam51/a8csp-project-template. When the Studio site'swp-contentis a clone of one, the run is in template mode (detected in Preconditions): it builds into that repository's theme and features mu-plugin under the template's conventions, perreferences/project-template-guide.md. - Studio site — path or registered name of the target Studio site. If the user named neither, list the sites (
studio site list --format=json) and ask which one, unless there is exactly one. Never pick a site by the look of its name: the run changes the site it is given. - Theme (optional) — the theme to build into, when the user names one. Otherwise the run makes a new theme, or in template mode uses the repository's (Preconditions step 10).
What ships with it
8 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
