create_collection

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only restates the purpose and names the collection types; it does not mention side effects (e.g., that the collection is saved to the store), required permissions, or behavior differences between manual and smart collections (e.g., smart collections require rules).

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, concise sentence with no filler. It efficiently conveys the tool's function and the key distinction between collection types, earning a 5.

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 straightforward create tool with fully described parameters, the description is minimally adequate. However, it lacks any context about what the API will return, whether additional rules are required for smart collections, or any setup considerations. Given no output schema exists, the description could have offered more guidance on the expected result or workflow, so it falls short of being complete.

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 describes 100% of the parameters including types, enums, and a description for each, so the baseline is 3. The description adds no parameter-specific meaning beyond saying 'manual or smart collection', which is already covered by the collectionType enum description. Thus it neither enhances nor detracts from schema information.

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 action ('Create') and the resource ('collection'), and further specifies the two types (manual or smart). This distinguishes it from sibling tools like update_collection or delete_collection, which have different verbs.

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?

The description implies usage for creating a new collection, but provides no explicit guidance on when to use this tool versus alternatives, or any exclusions. There is no mention of prerequisites or when a manual vs smart collection would be appropriate, leaving the agent to infer from the type name.

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