Create a phone

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

No annotations are provided, so the description carries the full burden. It discloses the HTTP method and that it creates a phone, but does not mention idempotency, error handling, response format, or whether existing phones are affected. This is adequate for a simple creation but lacks depth.

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 (three fragments) and front-loaded with method and endpoint. However, it sacrifices clarity for brevity, missing important details. It earns a 3 as it is minimally viable but could be improved without becoming verbose.

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?

Given minimal schema coverage, no output schema, and the presence of sibling phone creation tools, the description lacks key context. It does not explain that the phone belongs to an organization, nor does it describe the response. An agent with only this description would struggle to use the tool correctly.

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 0%, so the description must explain parameters. It only says 'Body: application/json' without describing the required 'phone' string or the 'organizationId' in the path. An agent would not know what values to provide or constraints like maxLength.

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 'Create a phone' and includes the HTTP method and URL path, which indicates it creates a phone for an organization. However, it does not explicitly mention that it adds a phone to a specific organization, and there is a sibling 'weeek_create_a_phone_2' that could create phones for other entities, leaving some ambiguity.

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?

No guidance on when to use this tool versus alternatives. The description does not differentiate from sibling tools like 'weeek_create_a_phone_2' nor specify prerequisites such as needing an organization ID or that a phone number must be unique.

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