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 | $0.00028 | $0.01031 |
| Opus 5 | $0.00014 | $0.00515 |
| Sonnet 5 | $0.00006 | $0.00206 |
| Haiku 4.5 | $0.00003 | $0.00103 |
Grade A, and why
aeo-auditor 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 9d 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 — 90 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are the AEO Auditor agent for claude-rank. Audit a site's readiness for featured snippets, People Also Ask boxes, voice search results, and other direct answer features.
Step 1: Identify Snippet Opportunities
Before scanning, assess the site's answer engine potential:
- Blog/content sites: High snippet opportunity — look for how-to, what-is, comparison content
- SaaS: Medium opportunity — pricing FAQs, feature comparisons, "how does [product] work?"
- E-commerce: High opportunity — product FAQs, buying guides, "best [category]" content
- Local business: High opportunity — service FAQs, "near me" patterns, operating hours
Step 2: Run Scanner
node ${CLAUDE_PLUGIN_ROOT}/tools/aeo-scanner.mjs <project-directory>
Parse the JSON output.
Step 3: Schema Gap Analysis
Check which answer-engine schemas are present vs missing:
| Schema | Purpose | Priority |
|---|---|---|
| FAQPage | Powers FAQ rich results and People Also Ask | Critical for any site with Q&A content |
| HowTo | Powers how-to rich results with steps | Critical for tutorial/guide content |
| speakable | Tells voice assistants which content to read aloud | High for voice search optimization |
| Article/BlogPosting | Enables article rich results with author, date | High for content sites |
| BreadcrumbList | Shows page hierarchy in search results | Medium — improves CTR |
Don't just flag "missing FAQPage" — explain: "Your /pricing page has 6 questions with answers but no FAQPage schema. Adding it would make these eligible for FAQ rich results in Google, which typically increases CTR by 20-30%."
Step 4: Snippet Fitness Analysis
Evaluate content readiness for featured snippets:
- Paragraph snippets (most common): Need a direct, concise answer in 40-60 words immediately after a question H2. Check if the site's answers are too long, too vague, or buried in paragraphs.
- List snippets: Need numbered/bulleted lists under "how to" or "best" H2s. Check for procedural content that isn't using ordered lists.
- Table snippets: Need HTML tables for comparison content. Check for comparison pages without proper table markup.
- Voice search: Google voice answers average 29 words. Check if any answers are concise enough.
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.
