List saved brands

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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is fully covered without the description. The description adds the shape of the result set (workspace fields) but says nothing about ordering, pagination, or empty-result behavior — though with zero parameters there is no filtering story to tell.

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 front-loaded sentence with the resource stated first and the payload fields parenthetical. Not a word 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?

With no parameters, three annotations, and an output schema present, the definition covers what an agent needs to call it. Minor gaps: whether all brands are returned at once and in what order are unstated, but the output schema covers the return shape.

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 tool takes zero parameters, so the baseline of 4 applies; nothing needs to be explained beyond the schema. The field list in the description actually describes outputs rather than inputs, so it does not compensate for any parameter gap because none exists.

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 ("the user's saved brand workspaces"). It also enumerates the returned fields (id, slug, website, status, name, logos). It is clearly distinct from create_brand/get_brand by the plural list framing, but it never names a sibling explicitly.

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, no exclusion, and no pointer to alternatives such as get_brand for a single brand. The only signal is the implicit plural in "List", leaving the agent to infer that this is the discovery call before a get_brand.

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