v1.0.0Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of behavioral disclosure. 'Get' implies a read-only operation, but the description does not address what happens when no user is authenticated, what the response contains, or any error conditions. With no output schema present, the return shape is entirely unspecified.
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?
At five words, the description is maximally concise and front-loads the core purpose immediately. Every word earns its place, and for a zero-parameter tool this brevity is appropriate rather than wasteful. It could add a clarifying detail, but nothing here is padding.
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 simplicity (zero parameters, no nested objects), the description conveys the essential operation adequately. However, with no output schema and no annotations, the response format and authentication-failure behavior are left unspecified — an agent cannot know what fields the user object contains or how errors surface. This is a meaningful gap, though minor for a widely understood pattern.
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 properties and 100% schema description coverage, so there are no parameters for the description to clarify. Per the zero-parameter baseline, the description is not required to add parameter-level semantics, and the phrase 'the authenticated user' correctly implies the call takes no inputs.
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 uses a specific verb ('Get') and resource ('the authenticated user'), clearly stating the tool returns the profile of the currently authenticated user. The word 'authenticated' implicitly distinguishes it from sibling lookups like get_user, get_users, and get_user_by_email, though that differentiation is not made explicit. Clear purpose, but it relies on inference rather than naming the distinction.
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 single-sentence description offers no guidance on when to use this tool versus alternatives. With 56 siblings including get_user, get_users, and get_user_by_email, an agent receives no explicit signal about the deciding condition (session-based lookup vs. ID vs. email). No exclusions, prerequisites, or alternative references are provided.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
