Create a collection

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

Annotations are empty, so description carries full burden. It reveals that new collections are private (important behavioral trait), but doesn't state permissions, rate limits, or effects on existing data. Adequate but not thorough.

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, no fluff. Front-loads the core verb and object, then adds key behavior and alternatives. Every sentence adds value.

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?

Tool is simple (create-only, no output schema) so description feels mostly complete. However, lacks guidance on required permissions, response format, or validation (e.g., uniqueness constraints). Adequate for a basic create tool but could do more.

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 75% (3 of 4 parameters have descriptions). The description adds meaningful context: parent_id for nesting, and the private-default behavior, which enhances understanding beyond the schema. Only the description parameter lacks schema description, but bulk is covered.

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 creates a collection, which is clear. It doesn't distinguish from sibling tools like update_collection or delete_collection, but naming and context make it distinct enough.

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?

Provides clear guidance on when to use it ('Creates a collection') and explicit alternatives (use update_collection to publish), plus optional nesting via parent_id.

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