compare_sake

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

No annotations provided; description explains output metric (spread per axis) but does not disclose whether operation is read-only, authentication needs, or rate limits. It partially compensates for missing annotations.

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?

Single sentence, front-loaded with 'Compare 2–5 sake', and uses line break effectively. Missing some detail but remains efficient.

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?

Output schema exists, so description need not explain return values, but it does mention spread per axis. However, it omits definition of the six flavor axes and parameter usage details, making it insufficient for complete agent guidance.

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 0%; description does not explain the single parameter 'brand_ids' beyond implying it identifies sake. Fails to clarify it must contain 2-5 integers or how to obtain them.

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 clearly states 'Compare 2–5 sake side by side across all six flavor axes' with specific verb and resource. It distinguishes from sibling tools like 'find_similar_sake' and 'get_sake_profile' which serve different purposes.

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?

Description implies usage for comparing 2-5 sake but does not explicitly state when not to use or provide alternatives. No mention of constraints like maximum count or what to do for more than 5.

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