A4.2/5.0

Behavior4/5

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

Annotations only declare readOnlyHint and openWorldHint; the description adds genuinely non-redundant behavior: the output is a heuristic score plus fixes, it is not a certification, and the call costs $0.01. That cost and the 'heuristic, not authoritative' caveat are exactly what an agent needs before invoking. It could still say whether the audit hits the live store over the network in a way that could fail or time out.

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?

Content is front-loaded and dense with no filler sentences — every clause carries information. However, the back half degrades into telegraphic fragments ('$0.01. One product: universal_product_url_to_json; purchase risk: ...') whose meaning is a little ambiguous to parse.

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?

With an output schema present, the description needn't explain return values, and it still characterizes them as a score plus fixes. Read-only safety is covered by annotations, cost and scope limits are stated in prose, and the single required parameter is documented in the schema — nothing an agent needs in order to call it correctly 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% — the domain and context parameters are already documented, including format constraints and the privacy note on context. The description adds nothing about the parameters, so the baseline of 3 applies; it neither compensates for nor undermines the schema.

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?

States a specific verb+resource (store readiness audit for shopping agents) and enumerates exactly what is examined: UCP, ACP, product schema, payment hints, robots.txt. It also names related siblings (universal_product_url_to_json, pre_purchase_merchant_trust_check), so an agent can place it in the catalog without opening another schema.

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 carves clear exclusions — 'no certification, checkout test or store changes' — and routes trust/commerce concerns to a named sibling, which is real usage guidance. It stops short of an explicit 'use this when you need X vs. agentic_shelf_schema_comparator' statement, so the trigger condition is implied rather than stated.

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