beel_get_customer

Read-onlyIdempotent

Fetches complete customer details for a company using company and customer IDs, enabling verification and management of customer records.

Instructions

Retrieves the complete details of a customer of this company.

Endpoint: GET /v1/companies/{company_id}/customers/{customer_id}

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
company_idYesUnique identifier (UUID) of the company the operation acts on — its identifier, not its NIF. It is the only source of context: the account that owns it is derived from it, and the `BeeL-Active-Company` header plays no part. A company you do not reach answers `403`, and so does a company that does not exist, so the existence of a company in another account is never disclosed.
customer_idYesCustomer ID

A3.8/5.0
Behavior3/5

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is covered. The description adds only that it returns 'complete details' and gives the GET endpoint; it does not add error behavior, auth requirements, or response format beyond the schema's 403 note, but nothing contradicts the annotations.

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?

One clear sentence plus the endpoint line; no filler. The core behavior is front-loaded and every word contributes.

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?

For a simple read-only single-resource fetch with fully annotated params and safe-operation hints, the description plus endpoint is nearly sufficient. The only gap is the absence of any response structure, which matters since no output schema exists, but 'complete details' is adequate guidance for a customer object.

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%; company_id is exceptionally well explained and customer_id is minimally described. The description itself adds no parameter semantics, but the baseline of 3 applies because the schema carries the full burden.

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?

The description uses the specific verb 'Retrieves' with the resource 'a customer of this company', and the endpoint line pins the exact operation. This clearly differentiates it from list/create/patch/delete customer siblings.

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

Usage Guidelines3/5

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

The verb 'Retrieves' and the singular resource imply it should be used when complete details of one known customer are needed, but the description never explicitly contrasts it with alternatives such as beel_list_customers or states prerequisites.

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