get_brand_book

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

With no annotations, the description carries the full burden for behavioral disclosure, but it only states 'Get brand book data'. It does not mention that the tool is read-only, what authentication is needed, or what the default response contains (relayed only in the 'elements' parameter description). The lack of any behavioral context is a significant 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 description is a single sentence and is concise in length, but it is under-specified. It fails to convey essential information that would help an agent use the tool correctly. Conciseness should not come at the expense of completeness; here it is too brief.

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?

Given the complexity (2 parameters, one with many options) and the lack of output schema, the description is incomplete. It does not explain what a brand book is, what the response structure looks like, or how the 'elements' parameter affects the result. Combined with the absence of behavioral notes, the tool is not adequately described for reliable agent use.

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 the baseline is 3. The description does not add any additional meaning to the parameters beyond what the input schema already provides (e.g., the 'elements' parameter has an exhaustive list of options in the schema). The description is neutral and does not improve parameter understanding.

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 'Get brand book data' is a verb and resource, but it is essentially a tautology of the tool name. It does not distinguish between 'get_brand_book' and the sibling 'get_brand_kit', nor does it explain what a 'brand book' specifically entails. The purpose is clear only at a surface level.

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?

No usage guidelines are provided. The description does not indicate when to use this tool versus alternatives like 'get_brand_kit', 'build_brand_kit', or 'import_brand_kit_modules'. There is no context about prerequisites or scenarios where this tool is appropriate.

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