Set temperature setpoint

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

The annotations already indicate destructiveHint, readOnlyHint=false, and idempotentHint, but the description adds no behavioral context beyond restating the action. It does not explain impact or side effects of changing a setpoint.

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 extremely terse and front-loaded, with no filler. The brevity is acceptable because the schema is rich and carries the parameter details.

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?

Schema and annotations provide most of the information needed to invoke the tool. However, the description lacks usage guidance and does not explain the potentially destructive nature of the operation beyond what the annotation flags.

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 description coverage is 100%, so the baseline is 3. The description's 'Preferred: idx' repeats the schema's own 'preferred over name when known' and adds no new meaning.

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 states a clear verb ('Set') and resource ('target temp'), and the tool name disambiguates it as a temperature setpoint. It is not a full 5 because 'temp' could momentarily be confused with the sibling tool set_color_temperature.

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?

There is no guidance on when to use this tool versus alternatives like set_switch_state or set_dimmer_level. 'Preferred: idx' is a parameter preference, not usage guidance.

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