get_profile

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

The description adds the behavioral constraint of requiring prior authentication, which is beyond what the readOnlyHint and idempotentHint annotations provide. It correctly indicates a read operation, aligning with 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 extremely concise: two sentences with no wasted words. It efficiently conveys purpose and a key prerequisite.

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?

While the tool has no parameters and no output schema, the description leaves 'profile status information' vague. It does not elaborate on what fields or data the agent can expect in the response, which is a gap given the lack of an output schema.

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?

With zero parameters, the schema coverage is 100% trivially. The baseline is 4 per the rule for 0 parameters, and the description does not need to add parameter meaning.

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 'Get', the resource 'profile status information', and the scope 'for the authenticated user'. It is specific and distinct from sibling tools that deal with foods, recipes, or exercises.

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?

It explicitly states that profile auth is required and suggests checking auth status first with 'check_auth_status'. This provides a clear prerequisite but does not discuss when to use this tool versus alternatives, such as other profile-related tools.

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