Create Project Segment Item

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

Annotations already indicate the tool is neither read-only nor destructive, which matches a creation operation. The description adds the success status code (201) and the return of the created object, providing additional behavioral detail beyond annotations.

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 four sentences, each contributing unique value. It starts with a clear purpose, then provides usage context, required parameters, and API reference—no redundancy or unnecessary detail.

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 creation tool with full schema coverage and no output schema, the description covers purpose, usage, required parameters, success response, and even API details. It leaves no critical gaps for an agent to understand how to invoke the tool.

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 100%, so each parameter is already documented in the input schema. The description only lists the required parameters without adding new semantics. Per guidelines, baseline 3 is appropriate when schema is comprehensive.

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 opens with 'Create Project Segment Item' and immediately clarifies its use for creating Work Breakdown Structure records in Procore. The API endpoint and success response (HTTP 201) are specified, leaving no ambiguity about the tool's function.

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?

The description states to use this tool for creating WBS records and lists required parameters. While no explicit when-not-to-use or alternatives are given, the sibling tools do not include a similar WBS-item creator, so usage context is sufficiently clear.

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