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

There are no annotations, so the description carries the behavioral burden. It states that the tool retrieves a profile and lists the returned sections, which implies a read-only operation, but it does not explicitly confirm safety, mention any variations in response, or describe edge cases. For a simple zero-parameter getter, this is adequate but minimal.

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 a single, front-loaded sentence with no filler. It immediately states the verb, resource, and content list, earning its place with every word.

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 zero-parameter, no-output-schema tool with a straightforward purpose, the description covers what an agent needs to know to select and invoke it correctly. The listed fields give a clear expectation of the return content, though it could have explicitly stated that no input is required or that the data is static.

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?

The tool has zero parameters, so parameter semantics are not applicable. Per the rubric, the baseline is 4, and the description adds useful context about what the resulting profile contains, though it does not need to explain any parameter behavior.

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 ('Get') and a clear resource ('Jeremy Twogood's profile'), then enumerates the exact content fields: bio, skills, clients, location, and social links. This clearly distinguishes it from sibling tools like get_project, get_reel, and get_resume, which target different resources.

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 makes it obvious that this tool is for retrieving profile information, which is the only sensible use given its zero parameters and the sibling set. It does not explicitly state when not to use it, but the resource-specific naming provides clear contextual guidance without needing exclusions.

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