10ML Perfume Finder

Search perfumes

search_perfumes
Read-onlyIdempotent

Search the 10ML Fragrance Index for perfumes by name, house, notes, accords, family, audience, season, occasion or style. Natural language works: 'fresh citrus summer scent for men' is understood. Set iconic to true for only the editors' iconic, era-defining classics ('must-know perfumes for her', 'iconic winter scents'). Use when someone describes what they want or names a perfume or house and you need matching perfumes. Not for the full profile of one known perfume (use get_perfume), not for 'something like X' (use find_similar_perfumes) and not for dupes or alternatives to a famous perfume (use find_perfume_alternatives). Returns ranked perfumes with house, year, family, accords, key notes, an editorial character line and 10ml.com links.

TDQS

A4.6/5.0
Behavior4/5

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

Annotations already declare readOnly/idempotent/non-destructive/closed-world, so the safety profile is covered. The description adds genuine context beyond that: natural-language queries are understood, iconic=true composes with any filter and needs no query, and it discloses the ranked return shape (house, year, family, accords, key notes, editorial line, 10ml.com links). It stops short of pagination/ranking-algorithm detail, which keeps it at 4.

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

Conciseness4/5

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

Front-loaded with purpose, then usage, then exclusions, then return shape – a logical order with no filler. It is dense across four sentences, but every sentence carries routing or behavioral information, so only marginal trimming is possible.

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?

An output schema exists, yet the description still summarizes the result contents, and it fully handles the hard part for a 15-parameter, 0-required search tool: deciding when this search is the right call versus its many siblings. Nothing needed to invoke it correctly is missing.

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

Parameters4/5

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

Schema coverage is 100%, so 3 is the floor. The description goes beyond the schema by explaining that free-text queries accept natural language and that iconic works 'with every other filter, and without a query' – cross-parameter semantics the schema does not state.

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+resource (search the 10ML Fragrance Index for perfumes) and enumerates the dimensions searched (name, house, notes, accords, family, audience, season, occasion, style). It explicitly distinguishes itself from get_perfume, find_similar_perfumes and find_perfume_alternatives, so an agent can select it without opening a sibling 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 an explicit trigger ('use when someone describes what they want or names a perfume or house and you need matching perfumes') plus three named exclusions that route to specific alternatives. Both when-to-use and when-not-to-use are covered with the receiving tool named.

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