Fl Project Set

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

No annotations are provided, and the description only states what is set without covering side effects, return values, error behavior, or the effect of omitting parameters. The burden is on the description, which does not disclose these behavioral details.

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 a single, efficient sentence with no unnecessary words. It directly conveys the tool's functionality without fluff.

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, the description covers the core action, but it lacks details on parameter combinations (e.g., setting numerator without denominator), return values, or error cases. Given that no output schema is shown, the description should have addressed these aspects more thoroughly.

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 defines three optional numeric/integer parameters but provides no descriptions. The tool description adds the interpretation of 'tempo (BPM)' and 'time signature' for numerator and denominator, giving some meaning beyond the raw schema. However, it does not explain parameter relationships, defaults, or ranges.

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 the tool's purpose: 'Set tempo (BPM) and/or time signature.' This is a specific action on project-level settings, distinguishing it from sibling tools that target channels, mixer tracks, or other elements.

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 when changing the project's tempo or time signature, but does not explicitly mention alternatives or conditions when not to use it. The context of sibling tools makes the scope somewhat clear, but the description itself offers no explicit guidance.

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