Battery Charge 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 behavior disclosure. 'Track a battery charge cycle' does not state whether the tool creates a new history entry, updates battery state, or has side effects such as changing due dates. The behavioral impact remains unspecified beyond the vague action word 'track.'

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 short and front-loaded with no filler, which is good for this dimension, but it is too underspecified to be considered well-structured for effective use. One terse sentence does eight words' worth of work, yet it sacrifices helpfulness.

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 zero annotation coverage, 0% schema description coverage, and two parameters, the description is far from complete. An agent cannot determine side effects, required prerequisite battery state, or parameter semantics from the provided text. The existing output schema does not compensate for these input and behavior gaps.

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 of what values to pass for 'battery' or 'tracked_time.' The agent is left to guess whether 'battery' is an ID, name, or ID, and what format or semantics 'tracked_time' expects. The description fails to compensate for the schema's missing documentation.

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 clear action verb and resource: 'Track a battery charge cycle.' It is clear enough to understand that this tool records or marks a charge event for a battery, and it is distinguishable from obvious siblings like battery_history_tool or battery_undo_cycle_tool, though it does not explicitly name them.

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 such as battery_history_tool, battery_update_tool, or batteries_due_tool. The sentence implies only the general scenario of tracking a charge cycle, but provides no conditions, exclusions, or routing hints.

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