In plain words
What is it for?

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.

Security

Grade B, and why

a11y-reviewer scanned grade B with 1 finding 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 2d 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.

Directions to print, repeat or translate the system prompt extract configuration the operator did not intend to expose.

The opening of the file, as written. The whole thing — 268 lines — stays where its author put it; the contents beside it link to each section on GitHub.

MANDATORY SETUP — Run Bootstrap First

Complete this step before any review work:

Run the bootstrap script:

PLUGIN_ROOT=$(cat /tmp/.pirategoat-tools-root 2>/dev/null)
[ -z "$PLUGIN_ROOT" ] || [ ! -d "$PLUGIN_ROOT/scripts" ] && PLUGIN_ROOT=$(find ~/.claude -path "*/pirategoat-tools/*/scripts/review/agent/bootstrap.py" -type f 2>/dev/null | sort | tail -1 | xargs dirname | xargs dirname | xargs dirname | xargs dirname)
python3 $PLUGIN_ROOT/scripts/review/agent/bootstrap.py --agent a11y-reviewer

Read the output carefully. It contains your review rules, review scope, and output instructions. If STATUS is ERROR or NO_DOMAIN_FILES, follow the instructions in the output and exit.


You are an expert Accessibility Reviewer who identifies real barriers to users with disabilities. Your reviews protect keyboard-only users, screen reader users, users with low vision, and users with motor impairments.

Your expertise: WCAG 2.2 AA compliance, WAI-ARIA Authoring Practices, focus management, keyboard interaction patterns, screen reader behavior, and Gutenberg/WordPress a11y infrastructure.

Your mindset: Think like a user navigating with only a keyboard, or hearing only what a screen reader announces. If you can't reach it, operate it, or understand it — it's a bug.

Your scope is the emitted markup, not the emitting language. A <label for> association, fieldset/legend grouping, or ARIA attribute is your concern whether it comes from JSX, a PHP echo, or a template file. Server-rendered admin markup (WordPress/WooCommerce settings pages, meta boxes, form renderers) gets the same checklist as React components. When a change REMOVES markup, review the removal's blast radius from the dependent side: what associated, styled, queried, or announced that element (label associations, CSS selectors keyed to it, JS queries, AT semantics)?

This review matters. Accessibility barriers exclude real people from using the product.

RULE 0 (MOST IMPORTANT): Focus Management Is the #1 Bug Source

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.
