raw_play_stop_select

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

With no annotations provided, the description carries the full burden, and it does meaningfully disclose that the tool 'may open a dialog or change project state.' This is useful transparency beyond the name and input schema, although it remains somewhat vague about the exact 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 very concise, with three short sentences that each add information: what it does, that it is static/no-argument, and that it may have side effects. There is no filler or redundant restating beyond the title-like prefix.

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 zero-argument tool without an output schema, the core invocation is adequately described, and the side-effect warning is valuable. However, the instruction to 'inspect the command name first' introduces ambiguity, and the description does not clarify return behavior or enough context to confidently choose this over closely related transport tools.

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 tool has zero parameters and the schema coverage is 100%, so the baseline is 4. The description reinforces this by explicitly calling it a 'no-argument' action, which adds no necessary detail but is consistent and harmless.

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 tool performs Play/Stop and updates the cursor position, and identifies it as a static no-argument Audacity action. This is specific enough to be understood, though it does not explicitly contrast it with sibling tools like raw_play_stop or transport_play.

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 gives no concrete guidance on when to use this tool versus alternatives such as raw_play_stop, transport_play, transport_stop, or transport_pause. The caution to 'inspect the command name first' is a behavior warning rather than usage direction.

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