spotify_get_devices

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

No behavioral details are disclosed. The description does not mention potential side effects, authentication requirements, or the nature of the result (e.g., read-only). Since no annotations are provided, the description carries the full burden but only states the basic action.

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, clear sentence with no unnecessary words. It is perfectly concise and well-structured for the simple purpose.

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?

For a simple getter with no parameters and no output schema specified, the description is sufficient. It explains the core functionality without overcomplicating, which matches the tool's straightforward nature.

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 tool has zero parameters, so there is nothing to add about parameter meaning. The baseline for 0 parameters is 4, and the description does not need to explain parameters. It is adequate.

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's function: retrieving the list of all available Spotify devices. It uses a specific verb 'get' and a clear resource 'devices', and it is distinct from sibling tools that handle playback or authentication.

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 does not explicitly state when to use this tool versus alternatives, but given its unique purpose among siblings, the context is implicit. No specific scenarios or preconditions are mentioned, so guidance is minimal.

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