set_project_time_signature

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only says 'Set' without revealing side effects, reversibility, or what 'default' means for existing items or future changes. This is a significant gap for a mutation tool.

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 extremely concise, front-loading the core action in the first sentence and clearly listing arguments with brief explanations. 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 two-parameter setter, the description provides a minimal viable level of detail. However, it leaves ambiguity about what 'default' implies and does not clarify how this relates to the sibling 'set_time_signature'. The existing output schema may cover return values, but behavioral side effects are unaddressed.

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 description explicitly defines both parameters with real-world examples ('4 in 4/4'), which is essential given the schema has no descriptions and 0% coverage. It compensates well, though it does not include constraints like valid ranges or denominator power-of-two requirements.

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 uses a specific verb ('Set') and a specific resource ('the default project time signature'), which makes the tool's purpose clear. However, it does not explicitly distinguish this tool from the sibling 'set_time_signature', so it falls short of a perfect score.

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?

There is no guidance on when to use this tool versus alternatives like 'set_time_signature' or 'get_project_time_signature'. The description provides no contextual framing or exclusionary statements, leaving the agent to infer usage from the name alone.

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