Find companies by director

lookup_director

Read-onlyIdempotent

Find Romanian companies by the name of a director or legal representative (ONRC). Diacritic-insensitive. Whole words: 'pop maria' finds POP MARIA, not POPA MARIANA; prefix=true matches prefixes. The registry has no personal ID, so one name can be several people: homonyms and byCounty say so. Use this when you know a person rather than a firm.

Input Schema

TableJSON Schema

Name	Required	Description
`name`	Yes	Director / representative name to search for (e.g. 'Ion Popescu'); diacritic-insensitive, each word a whole word of the name.
`fields`	No	Optional: keep only these company fields in each row, comma-separated (companyName,cui,county,risk; dotted paths such as risk.level work). Without it the full record is returned.
`prefix`	No	true matches each word as a prefix ('pop' also finds POPA, POPESCU); default false (whole words).
`compact`	No	Optional: true keeps a short preset per row (name, CUI, county, city, legal form, risk level and what it did not check, phone, website, latest revenue and headcount, record url).
`max_results`	No	Maximum number of companies to return (1-100, default 10).

Output Schema

TableJSON Schema

Name	Required	Description
`asOf`	No	What to cite: registry (ONRC snapshot date), financialYear (fiscal year of the figures), anaf (day of the ANAF data), snapshot, published, source.
`note`	No	What homonyms means for this name.
`error`	No	Set only when there is no answer (empty_query, invalid_cui, data_unavailable, plan_required ...); such a call is not counted.
`match`	No	words (whole words) or prefix.
`query`	No	The name as given.
`total`	No	Every matching firm, not just the rows returned.
`fields`	No	The company fields kept when fields or compact trimmed the rows.
`source`	No	Data source: onrc (registry) or mfp (Ministry of Finance filings).
`message`	No	A sentence for the caller.
`results`	No	The company records, best first.
`byCounty`	No	Matching firms per county.
`homonyms`	No	true when the matches span several counties (likely several people).
`returned`	No	Rows in results. Every list answer carries it with this one meaning.
`warnings`	No	Notes on how the request was read (a clamped limit, a widened CAEN code, an ignored field).
`attribution`	No	The credit line to keep when redistributing the data (CC BY 4.0).
`distinctCounties`	No	Number of counties the matches are in.
`totalIsLowerBound`	No	true when the scan stopped early and total is a minimum.

A4.2/5.0

Behavior4/5

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

Annotations already cover the read-only/idempotent safety profile, and the description adds genuine behavioral context: diacritic-insensitivity, whole-word matching, and the important caveat that the registry has no personal ID so one name can map to several people (homonyms, byCounty). It doesn't discuss pagination or result limits, keeping it just short of 5.

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 the core purpose, then scoping details, then the routing rule. Dense but each sentence carries a distinct fact; a semicolon-packed third sentence is the only mild drag.

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?

With 5 parameters, full schema coverage, an output schema, and annotations carrying the safety profile, the description supplies everything an agent needs, including the crucial matching-semantics and homonym caveats.

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 100%, so prefix, fields, compact and max_results are already documented. The description reinforces prefix semantics with a concrete example ('pop maria' finds POP MARIA, not POPA MARIANA), which is marginally useful but largely duplicates the schema.

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 (find) and resource (Romanian companies by director/legal representative) with the ONRC registry named. This clearly separates it from firm-oriented siblings like lookup_companies and match_companies.

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?

Gives an explicit routing rule: 'Use this when you know a person rather than a firm.' It clearly implies the opposite case is served by other lookup tools, though it does not name a specific sibling to prefer.

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