get_return_track_devices

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

No annotations are provided, so the description must carry the transparency burden. It accurately states a read operation but does not disclose any behavioral traits such as what 'all devices' includes, whether hidden devices are returned, or behavior with invalid return_index. For a simple getter this is minimal but not misleading.

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 succinct, with one clear sentence plus a parameter definition. No wasted words or redundant 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?

This is a straightforward single-parameter getter with an output schema provided. The description explains the essential input and outcome. It omits error handling details, but the output schema covers return values, making it adequately complete for the tool's complexity.

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 provides only an integer return_index with no description. The tool description compensates by explaining 'Zero-based index of the return track', adding meaning about the parameter's offset and purpose. This is clear and valuable.

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 explicitly states 'Get a list of all devices on a return track', which clearly names the action (Get) and the resource (devices on a return track). This distinguishes it from sibling tools like get_return_device_parameters and get_master_track_devices.

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 gives no guidance on when to use this tool versus alternatives such as get_return_track_sends or get_track_info. No exclusions, prerequisites, or alternative tool references are provided.

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