set_track_arm

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It explains the on/off action clearly, which is useful. However, it does not disclose potential side effects such as exclusive arming (disarming other tracks), whether the operation is reversible, or what happens if the track index is invalid. The description covers the basic behavior but lacks depth.

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, concise sentence that front-loads the action and immediately explains the value mapping. There is no redundant information or 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?

The tool is simple, and the output schema exists (so return values are not a penalty). However, the description lacks contextual details that would help an agent understand the full scope: no mention of exclusive arming behavior, whether playback must be stopped, or the relationship to recording tools like record_audio. The description is minimally sufficient but leaves room for important contextual assumptions.

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 description coverage is 0%, so the description must compensate for parameter meaning. It does so for the 'on' parameter by explicitly mapping True to arm and False to disarm. The 'track_index' parameter is only named in the schema, but its meaning is self-evident. Given only two parameters, this partial compensation is effective.

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 uses a specific verb ('Arm'/'disarm') with a clear resource ('a track') and purpose ('for recording'). It uniquely distinguishes this tool from all sibling tools, as no other tool handles track arming. The addition of on=True/False mapping further clarifies the action.

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 provides no explicit guidance on when to use this tool versus alternatives. It does not mention any prerequisites, such as needing to be in a recording session, or that arming is typically followed by start_playback or record_audio. There are no exclusions or alternative tool references.

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