list_sponsors

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

Discloses pagination, credit cost, and the output fields. Though no annotations exist, the description implies a read-only operation without explicitly stating so, which is a minor 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?

Two sentences cover purpose, output, alternative, and cost. No wasted words, front-loaded with key information.

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?

Describes returned fields, pagination mechanics, and sorting options. Lacks details on field interpretation (e.g., sponsoringPlatforms format) but overall adequate for a list tool with well-documented parameters.

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 coverage is 100% with good parameter descriptions. The description does not add additional meaning beyond what the schema provides, so baseline 3 is appropriate.

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 clearly states the tool lists every brand in CreatorDB with specific fields, and distinguishes from search_sponsors for filtered browsing. The verb 'list' and resource 'sponsors' are precise.

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?

Explicitly says to use search_sponsors when filtering is needed and that this tool is for browsing the full catalog. Also mentions credit cost per page, guiding efficient use.

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