homey_get_device_insights

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

No annotations are provided, so the description carries the full burden. 'Retrieve' clearly indicates a read-only operation, but there is no disclosure of return format, pagination, or any restrictions. The description adds minimal behavioral context beyond the operation itself, making it adequate but not rich.

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, front-loaded sentence that conveys the essential purpose without any redundant information. Every phrase 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?

Given that there is no output schema and no annotations, the description should explain what the tool returns. It does not describe the response structure or the nature of 'insight logs', which is a gap for an agent that needs to consume the result. However, the tool is simple with clear parameters, so the description is not severely incomplete, but it could be more comprehensive.

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 50%: logId is described, but resolution is not. The description adds 'for any device capability' and 'over a period', which gives some context but does not explain parameter syntax or the effect of resolution. The enum values are self-explanatory, so this does not significantly handicap the agent, but the description does not fully compensate for the missing schema coverage.

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 clearly states the tool retrieves historical logs for device capabilities over a period, using the specific verb 'retrieve' and specifying the resource ('historical logs for any device capability'). This distinguishes it from sibling tools like homey_get_live_insights (live data) and homey_get_energy_data (energy-specific).

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 implies the tool is for historical data retrieval over a specified period, which contrasts with live insights. However, it does not explicitly mention when not to use it or name alternative tools, so it falls short of a 5 but provides clear context.

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