mcp_opendaw_set_time_signature

Set the project's time signature by specifying the numerator (beats per bar) and denominator (note value per beat), such as 4/4 or 6/8.

Instructions

Set the project time signature (e.g. 4/4, 3/4, 6/8, 7/8).

numerator: Number of beats per bar (top number, e.g. 4, 3, 6, 7). denominator: Note value per beat (bottom number: 4=quarter, 8=eighth).

Behavior2/5

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

No annotations are provided, so the description must carry the burden of behavioral disclosure. It only says 'set', implying a mutation, but gives no information about side effects on existing signature changes, reversibility, or required project state. For a write operation, this is a significant gap.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is two short sentences plus a structured breakdown of the two parameters. Every line adds value, with no filler or repetition of schema details. It is front-loaded with the main purpose.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description covers the core function and both parameters adequately for a simple setter, and an output schema exists so return values need no explanation. However, it omits constraints like valid denominator ranges and does not address differences from add_signature_change, leaving minor gaps. Overall it is sufficient but not exhaustive.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters5/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema only specifies integer types with no descriptions (0% coverage). The description compensates fully by explaining numerator as 'Number of beats per bar' and denominator as 'Note value per beat,' including mappings like 4=quarter and 8=eighth. It adds substantial semantic meaning and usage examples beyond the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description opens with 'Set the project time signature'—a specific verb+resource. It provides concrete examples (4/4, 3/4, 6/8, 7/8) and distinguishes the tool by scoping it to the project time signature. This clearly differentiates it from siblings like set_bpm or set_groove_shuffle.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage by stating the action, but does not explicitly say when to use this tool versus alternatives like add_signature_change. It offers no when-not-to-use conditions or exclusions. The context is clear but not differentiated from related time-signature tools.

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