get_inverter_info

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

With no annotations provided, the description carries the full burden, but it only states the operation and nature. It doesn't disclose behavioral traits such as whether it returns data for all devices by default, potential pagination, error behavior, or auth requirements. 'Static' adds minor context but is insufficient.

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 without fluff, effectively conveying the core purpose. It could be enriched with more context, but it earns its place and remains appropriately sized.

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 tool with one optional parameter and no output schema, the description is minimal but adequate. It clearly states the tool gets static inverter info but leaves the return format and scope details to the schema. Given the sibling context and simplicity, it's complete enough for basic use but has gaps.

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 already provides a clear description for the single parameter ('Specific device ID (optional, defaults to all devices)'), and coverage is 100%. The tool description adds no additional parameter semantics, so the baseline of 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?

The description uses the specific verb 'Get' with the resource 'static inverter information,' clearly distinguishing it from real-time siblings like get_inverter_realtime via the word 'static.' However, it doesn't mention the optional deviceId parameter that the schema provides, so it's clear but not fully differentiating from other static getters.

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 offers no guidance on when to use this tool versus alternatives. It does not explicitly state that it's for static data or contrast with real-time tools, and there are no exclusions or alternative tool references. The word 'static' only implies usage context.

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