get_current_user_profile

Does 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. It only states the tool retrieves profile information but does not mention authentication requirements, what fields are returned, potential errors, or any side effects. The description is too sparse to convey expected behavior.

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, which is concise and free of fluff. However, its brevity is not an advantage here because it omits essential information. The structure is minimal but not poorly organized; it simply lacks content.

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?

With no output schema, the description should at least indicate what kind of profile information is returned (e.g., name, email, playlists). It does not. It also fails to clarify the scope of 'current user' or the authentication context. For a simple tool, this is incomplete.

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 has one parameter (access_token) with 0% description coverage. The description does not mention this parameter at all, leaving the agent to infer its purpose from the schema alone. Since the schema is minimal, the description should have explained the token's role but does not.

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 retrieves the current user's Spotify profile. It uses a specific verb ('Get') and resource ('current user's Spotify profile information'). However, it does not explicitly differentiate from the sibling 'get_user_profile', which could cause ambiguity about whether this is for the authenticated user vs another user.

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 description provides no guidance on when to use this tool versus alternatives like 'get_user_profile' or other Spotify tools. There is no mention of prerequisites, context, or when not to use it. The user is left to infer usage from the name and description.

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