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 states the create action and gives no information about idempotency, duplicate handling, permissions, side effects, or the response format.

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 very short and front-loaded, placing the core action first. The appended API-reference link is generic and adds little local value, but the overall structure is efficient.

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 one-parameter create operation with no annotations and no output schema, the tool still needs behavioral context such as duplicate behavior, authentication requirements, or expected response. The single-sentence description leaves these gaps and does not help an agent distinguish it from related portfolio tools.

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 description coverage is 100% for the single 'portfolio' parameter, and the schema already describes it as 'Portfolio name.' The description adds no additional parameter-level meaning, so the baseline of 3 applies.

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 uses a specific verb and resource ('Create a portfolio'), so the core purpose is clear and not tautological. However, it does not explicitly distinguish itself from sibling tools like portfolioDelete, portfolioList, or portfolioDomainAssociate.

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?

There is no when-to-use or when-not-to-use guidance, and no mention of alternatives such as portfolioDomainAssociate for attaching domains or portfolioList for viewing portfolios. An agent receives no explicit decision support beyond the action itself.

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