calculate_velo_development

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

With no annotations provided, the description carries full burden. It describes the tool as a calculator (implying idempotent read-only operation) and lists return values, but does not disclose any potential side effects, performance implications, or usage constraints beyond the schema. This is adequate for a simple computation but lacks depth.

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 two concise sentences: first states purpose, second adds return structure and sibling reference. It is front-loaded and every sentence serves a purpose with no redundancy.

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?

Given the tool's simplicity, an output schema exists, and the description mentions returns, it is mostly complete. It could include a brief note on when to use (e.g., for cycling gear optimization) but is sufficient for a standalone calculator.

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 description coverage is 100% with unit info and defaults, so baseline is 3. The description adds no further parameter-level detail; it only contextualizes the overall calculation. It does not enhance understanding beyond the schema.

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 function: 'Calculate bicycle development in meters per pedal revolution.' It specifies the output structure and distinguishes itself from sibling tools by referencing a specific domain (bicycle) and pointing to related calculators via 'See list_bundles for related sport calculators.'

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 for bicycle gear calculation but does not explicitly state when to use this tool versus alternatives. It only indirectly guides via 'See list_bundles for related sport calculators,' which is insufficient for clear differentiation from sibling tools.

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