calculate_time_signature_beats

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

No annotations are present, so description carries full burden. It only states the tool calculates and returns a time signature, with no mention of side effects, permissions, or other behavioral traits. This is minimal transparency.

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 with two sentences. It is front-loaded with main purpose and includes a reference to related tools. While efficient, it could be slightly more informative without adding bulk.

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 description covers the core functionality but leaves interpretation of 'duration' ambiguous. Since an output schema exists (though not shown), the description is adequate but not comprehensive. Complexity is moderate, so a score of 3 fits.

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 coverage is 100% with descriptions for all parameters. The description adds no extra semantic value beyond the schema, so the baseline score of 3 is appropriate.

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 states 'Calculate total beats and duration for a musical passage in bars.' This provides a specific verb and resource, making the purpose clear. However, it does not explicitly distinguish this tool from siblings like 'calculate_bpm_to_ms', so it loses a point.

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 implicitly guides use for musical passage beat/duration calculation. It mentions 'See list_bundles for related 'musique' calculators', providing a pointer to alternatives, but lacks explicit when-to-use or when-not-to-use instructions.

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