transport_pause

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

No annotations are provided, so the description carries full burden. While 'pause' implies a state change operation, the description doesn't disclose whether this requires specific permissions, what happens to paused content, whether the pause is reversible, or what the expected behavior is for different layer types. For a mutation tool with zero annotation coverage, this is insufficient.

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, efficient sentence that gets straight to the point with no wasted words. It's appropriately sized for a simple tool with one parameter and clear functionality.

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 mutation tool with no annotations and no output schema, the description is inadequate. It doesn't explain what 'pause' means operationally for each layer type, what the expected outcome is, whether there are side effects, or what happens to other layers. Given the complexity of media control systems and the lack of structured documentation, more context is needed.

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 100%, with the single parameter 'layer' fully documented in the schema with enum values. The description adds minimal value by listing the enum values in parentheses, but doesn't provide additional context about what each layer type represents or how pausing differs between them.

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 states the action ('Pause') and the target ('the specified layer'), specifying the three possible layer types. It distinguishes this as a pause operation rather than other transport actions like play or skip, but doesn't explicitly differentiate from similar pause operations on other resources among the many sibling tools.

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 guidance on when to use this tool versus alternatives. With many sibling tools for controlling different media layers and transport operations, there's no indication of prerequisites, timing considerations, or what other tools might be more appropriate in different scenarios.

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