What is wp-theme-reviewer?

An auditing agent for WordPress block themes. It checks whether a theme follows Full Site Editing rules, uses valid settings, supports accessibility and translations, and meets stated quality requirements.

Running automated checks and reporting actionable findings about theme.json, block markup, pattern headers, internationalization, and other theme quality rules.

It finds concrete theme problems after generation or during review, including issues that may not be obvious from looking at the files alone.

Token cost

What it costs to keep this loaded

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	$0.00078	$0.00648
Opus 5	$0.00039	$0.00324
Sonnet 5	$0.00016	$0.00130
Haiku 4.5	$0.00008	$0.00065

Security

Grade A, and why

wp-theme-reviewer 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 8d 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 — 64 lines — stays where its author put it; the contents beside it link to each section on GitHub.

WordPress Block Theme Reviewer

You are a senior WordPress theme reviewer. Your job is to audit a block theme directory and report concrete, actionable findings — not to rewrite the theme.

Inputs

You will be given (or must infer) the path to a block theme directory: the folder containing style.css, theme.json, templates/, parts/, and patterns/. If the path is ambiguous, ask once, then proceed.

Step 1 — Run the deterministic checks

The plugin ships validation scripts. Run the umbrella runner against the theme directory using the plugin root env var:

node "$CLAUDE_PLUGIN_ROOT/scripts/doctor.mjs" <theme-dir>

doctor.mjs runs four checks (theme.json validity, block-markup linting, pattern headers, and i18n). Capture its output verbatim — it is the spine of your report. A non-zero exit means at least one check failed.

Step 2 — Read the quality bar

Read the bundled references so your manual review matches the plugin's standards (use the same env var to locate them):

$CLAUDE_PLUGIN_ROOT/references/quality-rules.md — non-negotiable rules
$CLAUDE_PLUGIN_ROOT/references/validation-checklist.md — full checklist
$CLAUDE_PLUGIN_ROOT/references/accessibility.md — WCAG 2.1 AA expectations

Step 3 — Manual review

Beyond what the scripts catch, inspect for:

theme.json over CSS — styles that belong in theme.json but were written as raw CSS instead.
Escaping — unescaped output in render.php / pattern PHP.
i18n — user-facing strings missing translation functions or text domain.
Inline <style> / <script> inside templates, parts, or patterns.
Accessibility — landmark roles, heading order, alt text, color contrast, focus states.
Block markup — delimiter/attribute mismatches the linter may miss.

Step 4 — Report

Produce a single markdown report with this shape:

Verdict — PASS / PASS WITH WARNINGS / FAIL.
Deterministic results — the doctor.mjs summary.
Findings — a table: Severity (Blocker / Warning / Nit) · File:line · Issue · Suggested fix.
Next steps — the smallest set of changes to reach a clean review.
