Brands in a brand list

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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=true, so the safety profile is covered. The description adds real value beyond that by enumerating the return shape (entity_id, display name, primary URL, status, criterion_id) and the cross-tool identity of entity_id. It says nothing about pagination or limits, but against these annotations that is a minor gap.

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?

The purpose is front-loaded in the first sentence, followed by tightly packed return-field detail and a link. Every sentence carries information an agent needs; nothing is wasted.

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 two-parameter read tool with full schema coverage, an output schema, and safety annotations, the description supplies the remaining workflow context (field meanings and the link to remove_from_brand_list). Nothing needed to invoke it correctly is missing.

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 are already documented in the schema, including that shared_set_id comes from get_brand_lists. The description adds no format, syntax, or defaulting detail beyond that, so the baseline 3 is correct.

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 ('List the brands inside a brand list') and implicitly distinguishes itself from the sibling get_brand_lists, which lists the lists themselves. It also ties the returned brand.entity_id back to suggest_brands' id, so an agent can place it precisely in the brand-list workflow.

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?

Context is clear through cross-references: criterion_id is flagged as what remove_from_brand_list needs, and shared_set_id is sourced from get_brand_lists, giving an agent natural use conditions. It stops short of an explicit when-to-use/when-not statement or naming alternatives as choices, so it does not reach full routing guidance.

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