raw_play_stop

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

With no annotations provided, the description carries the behavioral disclosure burden. It openly warns that the action 'May open a dialog or change project state,' which is useful side-effect transparency. It does not enumerate all possible state changes, but for a toggle action the primary effect is clear.

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 three short sentences with no filler. The core action is front-loaded, and the additional notes about being static and potential side effects each add relevant information. The 'PlayStop:' prefix is slightly redundant but harmless.

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 zero parameters, no output schema, and no annotations, the description covers the essential facts: what it toggles, that it takes no arguments, and potential side effects. It omits an explicit comparison to raw_play_stop_select, but the toggle semantics are sufficient for correctly invoking this simple action.

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 schema has zero properties, so there are no parameter semantics to explain. The description reinforces this with 'no-argument,' matching the schema exactly. A baseline of 4 is appropriate for a zero-parameter tool.

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 verb and resource: 'Toggle playback on and off.' It further clarifies it is a 'Static no-argument Audacity action,' which helps distinguish it from parameterized or play/stop siblings. This is not a tautology and clearly conveys what the tool does.

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 purpose statement implies when to use the tool (when toggling playback), but it does not explicitly mention alternatives or exclusions relative to siblings like raw_play_stop_select, transport_play, or transport_stop. The instruction to 'inspect the command name first' is a caution, not a usage routing directive.

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