Battery Undo Cycle Tool

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

With no annotations, the description alone must disclose behavioral traits. 'Undo' implies a mutation, but it does not explain the effects (e.g., whether the cycle is deleted, whether the action is reversible, what happens to associated stock or state), nor does it mention idempotency or failure conditions. The description is minimal and leaves key behaviors unspecified.

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, front-loaded sentence with no filler. It achieves maximum conciseness and structural efficiency for the information it conveys.

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?

While the output schema exists and there is only one parameter, the description is incomplete for a mutation tool. It fails to explain how to obtain the cycle_id, what the undo action entails, whether it can be undone, or any side effects. An agent would need additional context to use it correctly and safely.

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%, so the description must compensate for the undocumented parameter. However, it does not mention cycle_id at all, nor does it explain what the value represents, where to find it, or its format. The parameter name is suggestive but the description adds no meaning beyond the schema.

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 verb ('Undo') and resource ('a tracked battery charge cycle'), making the tool's purpose immediately clear. It is also distinguishable from siblings like battery_charge_tool and battery_history_tool by the combination of name and description, even without an explicit alternative reference.

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 about when to use this tool, prerequisites (e.g., how to obtain a cycle_id), or when not to use it. The description does not mention alternatives, exclusions, or conditions that would help an agent decide between this and other battery-related tools.

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