Get room setpoint history

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

Annotations already cover readOnly/idempotent/non-destructive safety, so the bar is lower, and the description still adds value: the returned data includes the periods during which each setpoint applied, and it states the default range. It does not discuss pagination or bounded-detail behavior, hence not a 5.

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?

Two sentences with no waste, and the content type plus default time window are front-loaded. Every sentence earns its place.

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?

With an output schema present, return values needn't be explained, and the description gives the resource scope plus default window for a 9-parameter tool. It falls slightly short by not clarifying that a room must be selected via room_id or room_name despite zero required params in the schema.

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 all nine parameters (including from/to, mode, scale, period, max_points) are already documented in the schema. The description adds only the default range, not the syntax or format of any parameter, so baseline 3 applies.

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?

States a specific verb+resource: setpoint (target temperature) history of a room, and adds that it includes the periods each setpoint applied. It implicitly distinguishes from netatmo_get_temperature_history (actual vs. target temperature) but never names a sibling explicitly, keeping it just shy of a 5.

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 default of 'last 24 h' is conveyed, but there is no statement of when to choose this over alternatives like netatmo_get_temperature_history or netatmo_get_heating_status, nor any prerequisites or exclusions. Usage is only implied through the resource wording.

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