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

The readOnlyHint annotation already establishes this is a safe read, so the bar is lower. The description usefully adds that results are grouped by category and include price and duration, plus that pagination is cursor-based — return-shape context the annotations do not provide. It stops short of stating default behavior for the optional kind parameter or how the cursor is obtained.

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?

A single dense sentence with the core purpose front-loaded and no filler. It is slightly overloaded, stacking output shape and pagination into one clause, but every element carries information.

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?

For a simple read-only list tool with no output schema, the description covers the return grouping, the key fields, and pagination — enough to call it. It omits the kind default, cursor acquisition, and any routing versus search_catalog, which are the remaining gaps.

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 0%, so the description must compensate. It implies shop_slug ('for a shop'), cursor ('cursor-based pagination'), and kind ('menu or service' maps to the product/service enum), giving partial semantic grounding. However it never names the enum values or states what happens when kind is omitted, leaving real ambiguity for a 3-parameter tool.

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?

States a specific verb and resource ('Retrieve available menu or service catalog items for a shop') and adds meaningful scope detail: grouping by category, price/duration fields, and cursor pagination. It does not, however, distinguish itself from the sibling search_catalog, so an agent cannot tell from the description alone which of the two to pick.

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 when-to-use guidance and no mention of the obvious alternative, search_catalog, which appears in the sibling list. The phrase 'available ... items' hints at a browse/listing context but no condition or exclusion is stated.

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