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 only says 'Start playing a clip' and does not disclose side effects like whether the clip loops, whether transport is started, or whether it stops other clips. This leaves significant ambiguity for an agent.

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, consisting of a one-sentence purpose and a clean parameter list. Every line contributes useful information without redundancy, making it easy to scan.

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?

This is a simple tool but the lack of annotations and output schema increases the need for context. Missing details about whether 'firing' a clip starts transport or how it interacts with start_playback/stop_clip leaves the agent without enough information to use it correctly in all situations.

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 description adds meaning for each parameter, which is essential given 0% schema coverage. However, it doesn't clarify whether indices are zero-based or one-based, nor explain the concept of a 'clip slot' in depth. The user_prompt telemetry explanation is helpful but incomplete.

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 'Start playing a clip' which clearly identifies the action and resource. The parameter names (track_index, clip_index) distinguish it from global playback tools like start_playback, though the description doesn't explicitly call out this differentiation.

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 versus alternatives like start_playback or stop_clip. There is no mention of prerequisites, such as the clip needing to exist, or whether this tool alone starts audio playback.

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