p4_user

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

With no annotations, the description's 'Get' verb conveys a non-mutating read operation, which is the main behavioral trait needed for a simple retrieval tool. It does not disclose additional context such as authentication requirements or error behavior, but for a low-risk getter this is minimally acceptable.

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 compact and front-loaded with no wasted words. It is appropriately sized for a simple tool, though the phrase could have been made more specific.

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 two optional, well-described parameters and simple read-only nature, this is minimally viable. However, there is no output schema and the description does not clarify what information is returned or how p4_user differs from p4_users, leaving notable gaps.

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%, so the parameters are already documented in the input schema. The description adds no extra meaning about the user or workspacePath parameters, matching the baseline for 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 states a clear action ('Get') and resource ('user information'), making the basic purpose understandable. However, it does not distinguish this singular-user tool from the sibling p4_users, so it falls short of full differentiation.

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 is given for when to use this tool versus alternatives such as p4_users, p4_client, or p4_info. The description only restates the purpose without offering selection criteria or exclusions.

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