GEO / AI Answer-Engine Readiness Audit

geo_audit

Read-onlyIdempotent

Score a page's readiness for AI answer engines like ChatGPT and Perplexity. Identify crawler blocks, JavaScript-rendered content, and missing structured data to fix citation visibility.

Instructions

Score how readily an AI answer engine (ChatGPT, Claude, Perplexity, Gemini, Copilot) can fetch, parse and cite this page. Weighted across: AI crawler access (25), server-rendered content (20), structured data (15), extractable structure (15), authorship & entity signals (10), freshness (8) and content depth (7).

Two things this catches that a classic SEO tool does not:

Pages that rank fine in Google but are invisible to AI assistants, because most AI crawlers do not execute JavaScript and the content only appears after hydration.
robots.txt rules that block AI search crawlers (OAI-SearchBot, Claude-SearchBot, PerplexityBot) — the ones that build citation indexes — as opposed to the training crawlers people usually mean to block.

Args:

url (string): the page to audit.
response_format ('markdown' | 'json'): output format (default 'markdown').

Returns: { geo{score, grade, signals[], top_recommendations[]}, rendering, crawler_access, llms_txt, robots }.

Example: "Is https://example.com/guide ready to be cited by ChatGPT?" -> geo_audit(url="https://example.com/guide"). Note: llms.txt presence is reported but deliberately NOT scored — it is a community proposal with no committed vendor support, and Google has stated it does not use it.

A4.4/5.0

Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so the description doesn't need to restate safety. It adds behavioral context beyond annotations: the rationale for not scoring llms.txt, the distinction between AI search crawlers and training crawlers, and the return structure. No contradictions with annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is moderately long but well structured: purpose, weighting, unique value, args, returns, example, and a clarifying note. Each section earns its place; the bullet points condense key differentiators. It is not overly verbose, though it could be tightened slightly without losing value.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a composite audit tool with two parameters and an output schema (present but not shown), the description is remarkably complete. It covers purpose, methodology, edge cases (llms.txt), example usage, and return structure. An agent has everything needed to decide when and how to invoke it, and the llms.txt note prevents a common misunderstanding.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% with descriptions for both url and response_format, so the baseline is 3. The description adds an example invocation ('Is https://example.com/guide ready to be cited by ChatGPT?' -> geo_audit(url=...)) and the exact return object shape, which goes beyond the schema and helps an agent understand parameter usage and output. That lifts it to 4.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description opens with a specific verb and resource: 'Score how readily an AI answer engine can fetch, parse and cite this page.' It enumerates the weighted categories and explicitly names the two unique catches (AI crawlers not executing JS and AI search crawler blocking) that distinguish it from classic SEO tools. This clearly separates it from the many sibling tools that focus on individual aspects like robots_txt_check or render_check.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies when to use this tool by contrasting it with 'classic SEO tools' and listing its composite nature, but it does not explicitly name alternative tools or conditions for selecting them. It does clarify what it does NOT score (llms.txt) and why, which helps an agent avoid misusing it. A clear exclusion is present, but explicit routing to siblings is missing.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
