itglue_get_user

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

No annotations are provided, so the description must bear the full burden of behavioral disclosure. It states 'Fetch' which implies a read operation, but does not explicitly confirm no side effects or describe any potential errors or authorization needs. The behavior is vague beyond the basic operation.

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 sentence that directly states the tool's purpose with no extraneous information. It is perfectly concise and front-loaded.

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 the tool is a simple retrieval with no output schema and well-documented parameters, the description is largely sufficient. However, the lack of behavioral transparency and usage guidance slightly reduces completeness for an agent that might need to understand side effects or alternatives.

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 input schema has 100% description coverage, including thorough documentation for formatOptions. The description adds no additional meaning beyond what the schema already provides; it merely says 'by id.' Baseline 3 is appropriate since the schema does the heavy lifting.

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 'Fetch a single IT Glue user by id.' The verb 'Fetch' plus the resource 'single IT Glue user' and the method 'by id' make the purpose specific and unambiguous. It distinguishes well from sibling tools like itglue_list_users or other get_ tools for different entities.

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 does not provide explicit guidance on when to use this tool versus alternatives. For a simple get-by-id operation, the purpose is self-evident, but there is no mention of when not to use it or any prerequisites. It meets the minimum clarity but lacks explicit usage direction.

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