build_beta_details__get

Read-onlyIdempotent

Fetch a single build beta detail by ID to retrieve its beta testing states and settings. Specify fields and include related build to reduce API calls.

Instructions

Read one build beta detail by ID. [GET /v1/buildBetaDetails/{id}]

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
idYesID from the matching list call.
includeNocomma-separated list of relationships to include Pull related records in the same call. Without it, checking a relationship costs one extra call per row returned.
fields_buildBetaDetailsNothe fields to include for returned resources of type buildBetaDetails Return only these attributes. A full row set can exceed 200 KB.

TDQS

A3.6/5.0
Behavior2/5

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

Annotations already declare readOnlyHint and idempotentHint, and the description adds no new behavioral context such as error behavior, response format, or rate limits. It merely restates the read operation without contradicting 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?

The description is one concise sentence plus the endpoint, with no filler or redundant wording. It is front-loaded and easy to parse.

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 single-get tool with a well-described schema and safety annotations, the description is largely sufficient. It does not spell out return values, but the fields_buildBetaDetails parameter implies possible attributes, and the schema notes the ID source.

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?

All parameters have descriptions in the schema (100% coverage), so the description adds no additional parameter meaning. The schema already explains the id, include, and fields parameters adequately.

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 a specific action 'Read' and a clear resource 'one build beta detail by ID', which unambiguously differentiates this from listing or updating tools. The endpoint reference reinforces the exact operation.

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 description implies use when an ID is known, but it does not explicitly mention when not to use the tool or compare it with siblings like build_beta_details__list or builds__build_beta_detail__get. Guidance is only implicit, not explicit.

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