Battery Create Tool

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. 'Create a battery object' only indicates the basic action. It does not mention persistence, created identifiers, duplicate-name behavior, or any side effects, which is a significant gap for a mutation tool.

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 extremely concise with no wasted words, which is structurally clean. However, it is so terse that it barely adds value over the tool title, making this under-specification rather than effective conciseness.

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 tool with four parameters, no annotations, and no usage guidance, the description is incomplete. The presence of an output schema helps with return values, but the description still leaves parameter semantics, when to create, and behavioral expectations unresolved.

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 0%, and the description adds no explanation for any of the four parameters. The description does not clarify that `name` is required or clarify the meaning or expected format of `used_in`, `description`, or `charge_interval_days`, leaving the agent without compensating information.

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 states a specific action ('Create') and a specific resource ('a battery object'), so the agent knows the core behavior. It does not explicitly differentiate itself from sibling battery tools such as battery_update_tool or battery_charge_tool, but the verb makes the purpose reasonably clear.

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 gives no guidance on when to use this tool versus alternatives, no prerequisites, and no indication of when creation is appropriate. It neither names sibling tools nor explains how to choose between creating and updating a battery.

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