TDQS

A4.2/5.0

Behavior4/5

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

Annotations already indicate readOnlyHint=false and destructiveHint=false, so the mutation nature is covered. The description adds value by specifying that the collection is 'owned by the authenticated user' and requiring OAuth sign-in, which are meaningful behavioral and environmental traits beyond the annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences with no waste. The core purpose, ownership constraint, and authentication requirement are front-loaded, and each piece of information earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a create tool with only three optional parameters and no nested objects, the description covers the key operational requirements (ownership and authentication). It does not mention return value, but that is common for create operations and the output is likely a collection object.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%: title, private, and description each have clear inline descriptions. The tool description does not add extra parameter semantics or examples, which is acceptable since the schema carries the full burden.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb ('Create') and resource ('a new collection') and constrains ownership to the authenticated user. It clearly distinguishes this from sibling tools like update_collection, delete_collection, and various read-only collection tools.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides necessary context: the tool requires OAuth authentication, and it gives a concrete prerequisite command. It does not explicitly name alternatives or when-not-to-use, but for a create operation the purpose is unambiguous and the authentication caveat is important guidance.

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