set_preferred_lm_link_device

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

No annotations are present, so the description carries full behavioral burden. It states the action (setting a preferred device) but fails to disclose side effects, persistence, error conditions, authorization needs, or impact on remote model resolution beyond the basic phrase. This is insufficient for a mutation tool.

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 concise sentence, front-loaded with the domain category 'Mesh & Network'. It is efficient and easy to parse, though it is too brief to include deeper context that would make it more useful.

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 setter with one parameter and no output schema, the description is minimally viable but lacks important context about when to use it, implications for the mesh/network, and relationship to sibling tools like manage_lm_link. It answers 'what' but not 'why' or 'when'.

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 100% coverage for device_name with a clear description. The tool description does not add any additional parameter semantics beyond restating the preference concept; baseline for high schema coverage is appropriate.

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 'Set' and a clear resource 'preferred LM Link device', with a qualifying phrase 'for remote model resolution'. This clearly communicates the action and scope, and it subtly differentiates from broader sibling tools like manage_lm_link, though it does not explicitly contrast alternatives.

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?

No guidance is provided on when to use this tool versus alternatives. There is no mention of prerequisites, use cases, or exclusions, leaving the agent without insight into how this tool fits into the broader workflow.

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