transport

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 names actions but does not describe their effects (e.g., whether 'record' starts or toggles recording, what 'goto_start' does to playback state, or side effects like project state changes).

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 exceptionally brief and front-loads the purpose, with no fluff or redundant prose. The action list is redundant with the schema but arranged clearly.

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 control tool, the description still leaves critical gaps: no explanation of action semantics, no output/return expectations, and no preconditions (e.g., whether a project must be open). An agent cannot reliably decide which action to invoke without more context.

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%, so the description must compensate. It merely repeats the enum values from the schema without adding meaning—'toggle_repeat' and 'goto_start' are left to the agent's inference, and the description does not explain the purpose or expected behavior of each action.

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 'Playback control' and lists six transport actions, giving a general sense of purpose. However, it is vague about the resource (e.g., DAW transport, project) and does not differentiate from siblings like 'action' or 'status'.

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 the listed siblings. There is no mention of alternatives, preconditions, or scenarios where a different tool would be more appropriate.

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