Behavior1/5

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

No annotations are provided, so the description carries full responsibility for behavioral disclosure. It completely fails to mention any behavioral traits such as idempotency, side effects (e.g., whether it modifies other resources), permission requirements, error handling, or what happens on duplicate names. For a creation tool, this is a critical gap.

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

Conciseness3/5

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

The description is a single sentence, which is concise. However, it is under-specified for the complexity of the tool. It sacrifices important details for brevity. Ideally, it could be front-loaded with the core purpose and then expand slightly on key aspects without becoming verbose.

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

Completeness2/5

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

Given 4 parameters, no output schema, and no annotations, the description is incomplete. It does not explain the overall workflow, return value (e.g., ID of new collection), or any constraints. Sibling tools and context signals suggest a larger system, but the description offers no integration context.

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 description coverage is 100%, so each parameter is already documented in the schema. The description adds no extra meaning about the parameters, such as their relationships or usage notes. At baseline, 3 is appropriate since the schema does its job, but the description could have provided complementary context.

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

Purpose4/5

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

The description 'Create a new organization collection' is a clear verb+resource pair. It distinguishes well from sibling tools like update_org_collection, delete_org_collection, and list_org_collections by specifying the resource type. However, it is very brief and lacks any elaboration on what creating a collection entails.

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

Usage Guidelines2/5

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

The description provides no guidance on when to use this tool versus alternatives. There is no mention of prerequisites, comparison with update_org_collection, or any context about the organizational hierarchy. The tool is one of many creation tools, and the description offers no decision-making support.

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