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

Annotations already cover readOnly, idempotent, non-destructive, and closed-world behavior, so the safety profile is settled. The description adds real behavioral value by disclosing that results are scored against community compliment, office-safety, and versatility data, which is the only signal about what the output contains since no output schema exists.

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?

A single dense sentence with the core purpose front-loaded and no filler. It runs long, but each clause (inputs, examples, scoring source) carries information rather than padding.

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 read-only, all-optional suggestion tool with no output schema, the description covers the inputs, gives occasion examples, and explains how the pick is scored. The remaining gap is routing relative to sibling recommendation tools, which the agent cannot resolve from this text alone.

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%, so all four parameters are already documented, and the enum values for gender and season are self-explanatory. The description adds richer occasion examples ('date', 'office tomorrow', 'night out') than the schema's bare 'The setting', but it never mentions the gender parameter at all, so it is a marginal net gain.

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?

States a concrete verb+resource: a fragrance suggestion for right now, driven by mood, occasion, and season. It is clearly distinguishable from data-lookup siblings like get_fragrance or search_fragrances, though it never contrasts itself with the similarly-shaped get_recommendations.

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 phrase 'for right now' implies a situational use, but there is no explicit when-to-use guidance, no exclusions, and no mention of when an agent should prefer this over get_recommendations or trending_fragrances. The agent must infer the boundary itself.

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