boxofficemojo_brands

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

With no annotations, the description carries the full burden, but it only mentions 'normalized rows' and 'public brand chart.' It does not disclose sorting behavior, default ordering, pagination, limits, or what fields the rows contain, leaving the agent without key operational detail.

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 only two sentences, but the first sentence 'Box Office Mojo brand chart' is a redundant restatement of the tool name, and 'brand chart' is repeated in the second sentence. It is short but not tightly written.

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 tool with two optional parameters, no output schema, and no annotations, this description is too thin. It lacks information about valid sort fields, result row structure, and how this differs from related Box Office Mojo tools, preventing confident invocation.

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 input schema has 100% coverage for both parameters, so the baseline is 3. The description adds no additional meaning beyond the schema's generic 'Sort field' and 'Sort direction,' and it does not clarify valid values or how they affect results.

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 states it 'Returns normalized rows from Box Office Mojo's public brand chart,' clearly identifying the resource and action. It does not explicitly distinguish itself from sibling tools like boxofficemojo_brand, but the plural 'brand chart' gives a reasonable sense of scope.

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 guidance is provided about when to use this tool versus alternatives such as boxofficemojo_brand, boxofficemojo_franchises, or other box office chart tools. The phrase 'brand chart' implies a use case but offers no exclusions or comparison.

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