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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is fully covered. The description adds only the payload contents, with no mention of auth needs, visibility restrictions (e.g. whether private fields are omitted per caller), or error behavior.

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

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

One compact sentence with no filler, and the field enumeration is front-loaded. It loses a point only because the missing verb makes it read as a field list rather than a statement of action.

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

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

No output schema exists, so the description carries the burden of describing return contents — and it does enumerate the returned fields thoroughly. Combined with the fully documented single parameter, an agent has enough to call it correctly, though a short usage sentence would close the remaining gap.

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

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

Schema description coverage is 100% and the single `shop` parameter already documents its origin and the optional-case for a shop's own address. The description contributes nothing about the parameter, so baseline 3 applies.

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

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

The description enumerates what the tool surfaces (name, address, CVR, socials, pickup/delivery flags), which makes the resource recognizable, but it is a noun-phrase fragment with no verb and no differentiation from the sibling `find_shops`, which is the tool an agent would most plausibly confuse it with.

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

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

There is no guidance on when to call this versus `find_shops` or the other shop-scoped tools; the only routing hint ('the shop value from find_shops') lives in the schema, not the description. Use context is implied by the field list at best.

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