get_battery_status

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

No annotations are present, and the description only states 'Get battery status' with no mention of behavior, return format, or side effects. It provides no transparency beyond the tool's name.

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 entire description is a single short phrase, but it is under-specified and redundant with the tool name. Rather than being appropriately compact, it omits essential context and fails to earn its place as a useful description.

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?

The tool has an output schema, but the description fails to clarify what 'battery status' includes or how it differs from sibling battery tools. An agent cannot reliably choose this tool based solely on the description, leaving the definition incomplete.

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 tool has zero parameters and a fully covered empty schema, so no parameter description is needed. The description adds nothing about parameters, but the baseline for zero-parameter tools is 4.

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 'Get battery status' is a direct restatement of the tool name 'get_battery_status' with no additional detail. It does not differentiate from sibling tools such as get_battery_voltage, get_battery_voltage_state, or get_battery_thresholds, and uses the vague term 'status'.

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?

There is no guidance on when to use this tool versus alternatives like get_battery_voltage or get_battery_thresholds. The description offers no context about scenarios, prerequisites, or exclusions.

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