10ML Perfume Finder

Perfumes by note

perfumes_by_note
Read-onlyIdempotent

List the perfumes and colognes in the 10ML Fragrance Index built around a note or ingredient (vanilla, oud, bergamot, tonka bean, jasmine, patchouli, leather, sandalwood...), most prominent first, optionally only where the note sits in the top, heart or base, or for an audience, season or occasion. Spelling variants and other languages work (agarwood finds oud, Vanille finds vanilla). Use for 'perfumes with oud', 'a vanilla scent for winter' or 'bergamot-forward colognes for men'. Not for explaining what a note smells like (use explain_note) and not for several notes at once (use search_perfumes with notes_include).

A4.3/5.0
Behavior3/5

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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so safety is fully covered. The description adds genuinely useful behavior beyond that: results are relevance-ordered by note prominence, and fuzzy/multilingual matching is applied to the note term ('agarwood finds oud', 'Vanille finds vanilla'). It says nothing about pagination behavior, page-size default or the concise-vs-detailed payload tradeoff, which the agent would need to plan multi-page retrieval.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Three tight sentences: what it returns and how it's ordered, what can be narrowed, then how it disambiguates from siblings. Scope and ordering are front-loaded, and no sentence is filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Nine parameters but only one required, all fully documented in the schema, an output schema present, and annotations covering the safety profile — so the description's remaining job is routing and matching behavior, both of which it covers. Nothing an agent needs in order to call this correctly is missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the baseline is 3. The description does add real meaning for the required note parameter by explaining that spelling variants and other languages are matched semantically, which the schema's bare examples do not convey. For position, gender, season and occasion it only restates the enum concepts already documented in the schema, so it does not clear the baseline by much.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb (List), the exact resource (perfumes and colognes in the 10ML Fragrance Index), the retrieval key (built around a note or ingredient), the result ordering (most prominent first) and the optional narrowing dimensions. It explicitly contrasts itself with two siblings, so an agent can route between perfumes_by_note, explain_note and search_perfumes without opening any schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Gives concrete positive triggers in user-query form ('perfumes with oud', 'a vanilla scent for winter', 'bergamot-forward colognes for men') and explicit exclusions with the correct alternative named for each ('use explain_note', 'use search_perfumes with notes_include'). When-to-use, when-not-to-use, and alternatives are all present.

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