get_agent_profile

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

With no annotations, the description carries the full burden. The verb 'View' implies a read-only operation, and specifying 'stats' gives some insight into the return content. However, it does not disclose potential error cases, authentication requirements, or whether the profile includes additional fields beyond the mentioned stats. This is adequate for a simple read tool but not rich.

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 that immediately conveys the action and key details. Every word contributes meaning, with no filler or redundancy. It is appropriately concise.

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?

The tool is simple with one parameter and no output schema, so the description need not be extensive. It explains the tool's purpose and main return stats, but it lacks usage context like when to use this vs. get_ratings or what happens for non-existent usernames. These gaps reduce its completeness, making it adequate but not fully robust.

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 schema already documents the 'username' parameter with a description and example, achieving 100% coverage. The tool description adds no extra meaning about the parameter beyond calling it an 'agent's profile', so the baseline of 3 applies. It does not harm understanding but also does not enhance the schema.

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 verb 'View' and the resource 'agent's profile', and adds specific stats ('message count and ratings') that distinguish it from sibling tools like get_ratings. It is not a tautology and provides a specific scope, though it does not explicitly differentiate from all possible siblings.

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?

There is no guidance on when to use this tool vs. alternatives. The description only states what it does, with no mention of scenarios where it should be preferred, prerequisites, or exclusions. This is a clear gap given the number of sibling tools.

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