Check store AI shopping readiness

check_store_ai_readiness

Read-only

Checks whether AI assistants and shopping agents can read an online store. Fetches the public store pages the user names, without running JavaScript. Returns the store's AI Shopping Readiness Index score if the store is in the Index, which AI crawlers its robots.txt allows, and whether one product page shows price, stock and product structured data in its HTML. Use when the user asks if AI can find, read or shop their store. Does not test checkout or log in. Use when the user gives a store or domain.

A3.9/5.0

Behavior4/5

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

Annotations already cover the safety profile (readOnlyHint, openWorldHint, destructiveHint=false), so the bar is lower, yet the description adds real behavioral context: it fetches public pages 'without running JavaScript' and reports specific artifacts (Index score, allowed crawlers, structured-data presence). It does not mention rate limits, failure modes for unreachable stores, or auth needs, keeping it short of a 5.

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?

Front-loaded with the core action, then the mechanics, then the outputs, then usage conditions — a logical order with no filler. The closing 'Use when the user gives a store or domain' partially restates the earlier usage sentence, a minor redundancy.

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

Completeness4/5

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

An output schema exists, so return values need not be spelled out, yet the description still summarizes the three result categories, which helps selection. Combined with full schema coverage and annotations, an agent has enough to invoke it correctly; only sibling disambiguation is missing.

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

Parameters3/5

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

Schema description coverage is 100% and both parameters are documented in the schema, so the baseline is 3. The description only indirectly adds meaning by tying the product page to the structured-data check ('whether one product page shows price, stock and product structured data'), without adding format or constraint detail beyond the schema.

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

Purpose4/5

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

States a specific verb and resource: 'Checks whether AI assistants and shopping agents can read an online store,' and details exactly what it inspects (robots.txt crawlers, structured data, Index score). It is clear, but it never names or contrasts itself with the sibling tools it overlaps with (check_ai_crawler_access, check_page_readability, check_product_page), so an agent cannot tell which one to pick from the text alone.

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?

Gives explicit trigger conditions ('Use when the user asks if AI can find, read or shop their store') plus an exclusion ('Does not test checkout or log in'). However, it offers no alternatives or routing guidance toward the narrower sibling tools, which is the main thing an agent would need when several readiness checks exist.

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