Battery Details Tool

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

With no annotations supplied, the description carries the full burden, and 'Return' reasonably signals a side-effect-free lookup. However, it does not disclose behavior for missing or unknown batteries, match semantics, preconditions, or error cases, leaving transparency only minimally adequate.

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?

One concise, front-loaded sentence states the action, target, and accepted identifier forms with no filler. Every word 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 one-parameter read operation with an output schema present, the description is mostly sufficient for a basic call. It is weakened by offering no pointer to related battery tools and no mention of not-found behavior, leaving a moderate gap in selection context.

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 only documents a required string property named 'battery' with 0% description coverage. The description adds real added meaning by clarifying that this single parameter may be either a name or an ID, which is important for correct invocation.

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 specific verb ('Return'), a resource ('battery'), and the accepted identifier forms ('name or ID'), so an agent knows what operation this is. It is more specific than a bare 'Battery Details Tool' label, though it does not fully distinguish itself from battery_history_tool or batteries_list_tool.

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 for when to use this tool over nearby siblings such as battery_history_tool, batteries_list_tool, or battery_charge_tool. The agent must infer usage context entirely from the title and sibling names, with no exclusions given.

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