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

Annotations already declare readOnly, idempotent, non-destructive, closed-world behavior, so the safety profile is covered. The description adds real value beyond that: it is paginated via offset, IDs must come from the response rather than being guessed, and the call is a prerequisite lookup step. It omits page size, ordering, and whether more pages remain.

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?

Four short imperative sentences, front-loaded with the workflow purpose before the ID and pagination mechanics. Every sentence carries a distinct instruction with 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?

For a one-parameter list tool with an output schema present, the description covers purpose, workflow placement, and pagination adequately, and need not explain return values. The remaining gap is pagination semantics (page size, end-of-results signaling), which is minor.

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?

The single offset parameter has 0% schema description coverage, so the description must compensate. "Page with offset" correctly signals offset is a pagination cursor rather than a page number, but gives no page size, default handling, or behavior when offset exceeds the result set.

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 names a specific verb+resource ("Find the user's brands") and implies a paginated listing, which an agent can distinguish from siblings like create_brand or check_brand_copy. It does not, however, explicitly contrast itself with other read-oriented siblings such as get_brand_guide, so sibling differentiation is only partial.

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?

It gives clear when-to-use guidance: call this before saving language or checking copy, then use a returned id rather than guessing. This effectively routes the agent into the correct workflow, though it names no explicit exclusion or alternative tool since none exists in the sibling set.

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