play_compare_tool

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

No annotations are provided, so the description carries full burden. It mentions playing tracks but does not disclose whether this modifies session state, requires a specific playback session, or has side effects like moving the playhead. The sequence 'then premix' is vague about what 'premix' entails.

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 sentence, which is concise and front-loaded, but it is under-specified. It earns a passing score for brevity but lacks substantive content that would help an agent decide to use it.

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 complexity of five parameters, no annotations, and an output schema that is not described, the description is inadequate. An agent would not know what dry_run or rerender do, nor what the required project_path refers to. The tool likely needs more context to be called correctly.

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 does not explain any of the five parameters (dry_run, end_sec, rerender, start_sec, project_path). It only hints at timeline range via start_sec/end_sec, but leaves dry_run and rerender entirely unexplained.

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 action (play) and resource (dialogue tracks and premix) for a defined timeline range, which distinguishes it from generic playback tools like play_audio_tool. However, it lacks explicit mention of the 'compare' aspect that the tool name suggests, making it slightly ambiguous.

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 like play_ab_tool or play_compose_tool. The description does not indicate prerequisites, context, or scenarios where this is preferred.

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