powerwall_get_solars

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

With no annotations and no output schema, the description carries the full burden of behavioral disclosure. 'Get' weakly implies read-only, but the description does not mention what data is returned, whether authentication is required, or any caveats about the response.

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?

A single, front-loaded sentence communicates the action and resource with no wasted words. Every part of the description 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?

For a zero-parameter getter, this is minimally sufficient to invoke, but 'solar array information' is vague and there is no output schema to clarify the exact return shape. The agent can call it, but the description leaves interpretation open.

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 input schema is empty, so parameter semantics are not applicable. Per the baseline for zero-parameter tools, the description need not add parameter details, and it correctly avoids inventing any.

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 names a concrete verb and resource: 'Get solar array information.' It is easy to understand what the tool does, but it does not explicitly distinguish itself from sibling getters like powerwall_get_powerwalls or powerwall_get_system_status, so it falls short 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?

No guidance is provided about when to use this tool versus the many sibling getters. The resource phrasing implies 'use when you need solar array info,' but there are no explicit alternatives, exclusions, or context cues for selection.

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