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

Annotations already declare readOnlyHint, idempotentHint and destructiveHint=false, so the safety profile is covered. The description adds ordering semantics ('newest first') and the shape of each returned record (id, brand name, status, image), which is real context beyond the annotations, though it says nothing about pagination behavior or volume.

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 dense sentence, front-loaded with the verb and resource, with the id/field detail and the downstream-consumer hint appended after the dash. No filler.

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?

With no output schema, the description carries the burden of describing return values and does so (id, brand name, status, image) in addition to ordering. Pagination is handled by the schema, so nothing an agent needs to call and consume this tool 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 limit and offset are already fully documented with defaults and caps. The description only implies ordering via 'newest first' and adds nothing about limit/offset semantics, so the schema does the heavy lifting.

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) and resource (account's logos), plus ordering ('newest first') and the fields returned. The dash clause naming get_logo and build_brand_kit makes it easy to distinguish from siblings like list_logo_models and list_brand_kits.

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?

Explains the tool's role in a workflow by stating the returned ids are what get_logo and build_brand_kit consume, which tells an agent when this list is the right entry point. It gives no explicit when-not condition or exclusion against the other list_* siblings, so it stops short of full routing guidance.

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