Find businesses

Read-onlyIdempotent

Search the DouxProcess Directory for US businesses by what the person needs (roofer, electrician, insurance agency...) and where (a city and state, a ZIP, or a state). Returns the matches in the published ranking order with license, how it was checked, phone, website and listing page. covered=false with a note means the directory does not hold that kind of business or place yet: say so, do not guess. Nobody pays for placement; listings affiliated with DouxProcess's owner carry a disclosure, pass it on. Do not rank, rate or recommend; show the options and let the person choose.

  3. First observed

TDQS

A4.1/5.0
Behavior4/5

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

Annotations already declare readOnly/idempotent/non-destructive, but the description adds genuine value: results come back in published ranking order, covered=false signals missing inventory, sponsor-affiliated listings carry a disclosure, and no paid placement exists. It omits pagination mechanics, though cursor/limit are only hinted at in the schema.

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-loads what the tool does and where it searches, then layers policy notes. All sentences are functional (covered=false, disclosure, no-ranking), though the list of returned fields overlaps the output schema and could be trimmed.

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

Completeness4/5

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

The output schema and annotations cover the return shape and safety profile, and the description supplies the missing behavioral policy around coverage gaps and disclosures. It leaves radius_miles and pagination unaddressed, but nothing critical for a correct call is absent.

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 coverage is 70%, so the schema already documents most params including where, query, category, and cursor. The description reinforces that 'where' accepts city+state, a ZIP, or a state, which matches the schema text rather than extending it, and it says nothing about radius_miles, limit, or page semantics.

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 (Search) and resource (DouxProcess Directory of US businesses), plus the two axes of search (what the person needs, and where). An agent can distinguish this from get_business (single lookup) and list_categories (category ids) without opening the schema.

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

Usage Guidelines4/5

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

Clearly scopes usage to need+location lookups and gives real behavioral rules: honor covered=false rather than guess, pass on disclosures, and do not rank/rate/recommend. It stops short of explicitly naming sibling alternatives (get_business, list_categories) as when-to-use switches, so it lands at 4 rather than 5.

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