set_time_signature

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

No annotations are provided, and the description does not disclose any behavioral traits such as side effects (e.g., whether existing clips are affected, if the change is destructive, or if it triggers any events). The agent lacks information about the impact of this mutation.

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?

A single sentence that is clear and to the point. No extraneous information.

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?

The tool has an output schema (not shown) which may document return values, but the description lacks context about behavior and parameter details. For a simple setter, it is minimally adequate but leaves gaps regarding safety and parameter semantics.

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 has no descriptions (0% coverage). The description gives examples that implicitly map numerator and denominator, but does not explicitly define them. This adds some meaning beyond the schema but could be more precise (e.g., 'numerator: beats per measure, denominator: note value for one beat').

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?

Description clearly states the tool sets the song's time signature with examples (4/4, 5/4, 7/8). The purpose is distinct from sibling tools which focus on other song properties like tempo or playback.

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?

Examples of common time signatures are provided, but there is no guidance on when to use this tool versus alternatives or prerequisites. The description implies direct use without specifying context like existing song state.

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