delete_return_device

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

With no annotations, the description carries the burden of disclosure. It clearly states the destructive action and provides zero-based indexing details, but it does not mention whether the action is reversible, what happens to subsequent devices, or any errors for invalid indices. This is adequate for a simple delete but lacks deeper context.

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 concise and well-structured: a one-sentence purpose followed by an args list. Every sentence adds essential information, with no fluff or repetition.

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 two-parameter destructive operation with an output schema, the description provides the essential details. It could be slightly more complete by noting implications (e.g., cannot be undone, check return track devices first), but it does not feel severely 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?

Schema coverage is 0%, so the description must explain parameters. It defines each parameter clearly with their zero-based nature (return_index and device_index). This adds meaningful semantics beyond the raw integer type, though it could include constraints like valid ranges or expected bounds.

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 starts with a specific verb ('Delete') and a precise resource ('a device from a return track's device chain'). It clearly distinguishes this tool from siblings like delete_device or delete_master_device by focusing on return tracks.

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?

Usage context is implied by the tool's name and description (for return tracks), but the description does not explicitly mention when to use this over delete_device or delete_master_device, nor any prerequisites like checking the device chain first.

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