set_scene_time_signature

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

No annotations are provided, so the description carries the burden. It states the basic action and includes parameter details, but it does not disclose side effects, prerequisites (e.g., scene must exist, Live 12+ only), or error behavior. For a simple setter, this is adequate but not rich in behavioral context.

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 brief and front-loaded with the main action. The Args block is somewhat redundant with the schema but adds valuable semantic details. It is appropriately concise with no wasted words.

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 setter with 3 parameters, the description covers all parameters and notes the Live 12+ constraint. The output schema exists, so return values need not be explained. It could mention prerequisites or error conditions, but the tool is simple enough that this is largely sufficient.

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 0% description coverage, but the description's Args section compensates fully by explaining scene_index as zero-based and giving examples for numerator/denominator (4 for 4/4). This adds significant meaning beyond the raw schema fields.

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 'Set the time signature for a specific scene' with a specific verb and resource. It specifically mentions 'scene' which distinguishes it from the sibling tool 'set_time_signature' that likely sets the global time signature. The version constraint 'Live 12+' adds further precision.

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 implies usage by noting 'for a specific scene' and the 'Live 12+' version requirement, but it does not explicitly state when to use this tool versus the sibling 'set_time_signature' or other scene-related tools. There is no explicit when-not or alternative guidance, though the scene-scoped context is a clear signal.

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