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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the agent knows this is a safe read. The description adds only that the endpoint is 'public', which lightly implies no auth is needed, but it says nothing about pagination behavior, page-window limits, or the shape of returned collection records. Adequate against annotations that carry the safety profile, but not rich.

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?

Two clipped sentences with zero waste; the purpose is front-loaded and the sibling routing follows immediately. Nothing redundant or padded.

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?

An output schema exists, so return-value explanation is unnecessary, and the annotations cover the safety profile. For a two-param, non-required filtered list tool, everything an agent needs to select and call it correctly is present.

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%, so both parameters (page default 1, limit default 50 max 250) are already fully documented in the schema. The description adds no syntax, format, or constraint details beyond what the schema provides, so the 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?

States a specific verb ('List'), resource ('collection records'), and scope ('The Body Shop's public collections endpoint'). It also names the sibling tools it is not, so an agent can distinguish it from thebodyshop_collection_products and thebodyshop_products without opening schemas.

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?

Explicitly routes the agent: thebodyshop_collection_products for items in one collection, thebodyshop_products for the general catalog, thebodyshop_search_suggest for typeahead. Each alternative comes with the condition that selects it, leaving nothing to inference.

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