get_user_profile

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

With no annotations, the description must disclose behavioral traits, but it only states the action. It does not mention whether the operation is read-only, if it requires authentication, if there are rate limits, or what the 'statistics' part entails. The verb 'Get' implies a read operation, but the absence of any usage caution is a gap.

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, front-loading the core purpose. It contains no redundant words or fluff, making it highly efficient for an AI agent to parse.

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 lack of an output schema and the simplicity of the tool, the description minimally conveys the purpose but omits details about what 'complete profile and statistics' includes. An agent cannot infer the return structure or fields, which is important for downstream use. The description is too sparse for a tool with many siblings.

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 zero parameters and 100% schema description coverage, so the baseline is 3. The description does not add parameter-level detail because none exist, which is acceptable. However, it could have clarified that no parameters are needed, but the schema already makes that obvious.

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 tool gets the current user's complete profile and statistics. The verb 'Get' and resource 'user profile' are specific, and it distinguishes itself from the sibling 'update_user_profile' which is for modifications. However, it does not elaborate on what 'complete profile' entails, leaving some ambiguity.

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 usage guidelines are provided. The description does not indicate when to use this tool versus alternatives, such as 'get_citation_stats' or 'get_credit_balance', nor does it mention prerequisites or limitations like authentication requirements. The agent is left to infer usage from the name alone.

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