get_user

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

Annotations provide readOnlyHint=true, and the description adds valuable context beyond this: it specifies the permission requirement ('Permissions:{'all_of': ['Read User Info']}') and details what information is returned (email, names, role, etc.). This enhances understanding of behavioral traits without contradicting 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 appropriately sized and front-loaded with the core purpose, followed by return details and permissions. It avoids redundancy, but the formatting with extra spaces slightly affects structure. Overall, it's efficient with minimal waste.

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's low complexity, high schema coverage, presence of annotations, and an output schema, the description is complete enough. It covers purpose, return values, and permissions, addressing key contextual needs without unnecessary elaboration.

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%, with the parameter 'user_id' well-documented in the schema. The description does not add significant meaning beyond the schema, as it only mentions 'by ID' without further details. Baseline 3 is appropriate given high schema coverage.

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 the specific action ('Get detailed information') and resource ('a Panther user by ID'), distinguishing it from sibling tools like 'list_users' which returns multiple users. It precisely defines what the tool does without being vague or tautological.

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 implies usage by specifying 'by ID' and listing returned fields, but does not explicitly state when to use this tool versus alternatives like 'list_users' or other user-related tools. No explicit guidance on prerequisites or exclusions is provided.

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