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

With no annotations, the description carries the full burden of behavioral disclosure. It simply lists action values without explaining side effects, prerequisites (e.g., whether the engine must be running), or what 'toggle' actually toggles between. This adds little beyond the action names.

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 and front-loaded, with no filler or redundant statements. The two-line structure directly conveys the core functionality and parameter values.

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 simple one-parameter tool, the description is minimally adequate but misses key context such as whether the engine must be started, the exact behavior of 'toggle,' or the effect on current playback. Given the lack of annotations and sparse schema, this could be more explicit.

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 input schema only declares a required string 'action' with no enum or description. The description explicitly lists the allowed values ('play', 'stop', or 'toggle'), providing essential semantic information that compensates for the 0% schema description coverage.

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 clearly identifies the tool's purpose: 'Control transport: play, stop, or toggle.' It names the specific resource (transport) and the distinct actions, which differentiates it from sibling tools like start_engine or set_position.

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 on when to use this tool versus alternatives. The description does not mention related engine controls (e.g., start_engine, engine_panic) or any prerequisites, leaving the agent to infer usage from the word 'transport' alone.

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