get_meter_realtime

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

No annotations are provided, so the description must fully disclose behavior. It only states 'real-time data' without mentioning return format, scope handling, defaults, or any side effects (e.g., whether it's read-only). For a get tool, some behavioral transparency is expected, but this is lacking.

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, clear sentence with no unnecessary words. It is well-structured and front-loaded with the core action. However, it is slightly under-specified for a tool with optional parameters, but conciseness per se is good.

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 the lack of output schema and minimal annotations, the description should provide more context about what 'real-time smart meter data' includes and how the scope parameter affects results. The single sentence leaves too many gaps for an agent to use the tool correctly.

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% for the single 'scope' parameter, including an enum and default value. The description adds no additional meaning beyond the schema, so it meets the baseline for high schema coverage but does not enhance understanding.

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 a specific verb ('Get') and resource ('real-time smart meter data'), making the primary purpose understandable. However, it does not distinguish this from sibling tools like get_inverter_realtime or get_sensor_realtime, which follow the same naming pattern and analogous descriptions.

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 usage for smart meter data, but it does not explicitly state when to choose this tool over others or mention any exclusions. The parameter 'scope' hints at System vs Device, but without guidance on which to use or when, guidance is only implied by the resource name.

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