create_brand

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

With no annotations provided, the description carries the full burden for behavioral disclosure. It only states the creation action without explaining potential side effects, permissions, idempotency, or response format. This is a significant gap for a mutation tool.

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, front-loaded sentence with no extraneous information. It clearly states the tool's purpose and is appropriately concise and easy to parse.

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?

The tool is a creation operation with 4 parameters and no output schema. The description provides no information about required fields, parameter meaning, dry-run behavior, or response. Given the lack of annotations and schema descriptions, the description is incomplete for an agent to confidently invoke the tool.

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 4 parameters with 0% schema description coverage. The description mentions none of the parameters (global_key, brand_name, dry_run, brand_description) or their semantics, leaving the agent to infer from parameter names alone. The description adds no value beyond the schema's parameter titles.

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 uses a specific verb 'Create' and a resource 'new brand', clearly distinguishing it from sibling tools like update_brand, delete_brands, and list_brands. The phrase 'for GenAI visibility tracking' adds context, making the purpose unambiguous.

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 on when to use this tool versus alternatives like update_brand or delete_brands. There are no prerequisites, exclusions, or context for selecting this over sibling tools. The only implied usage is 'when you need to create a new brand,' which is insufficient.

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