[Read] Get a build

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

With no annotations, the description discloses read-only behavior, which is a key safety signal. However, it does not describe error handling, authentication requirements, or response format, leaving some behavioral aspects unspecified.

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

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

The description is two short sentences, front-loaded with 'Read-only,' and each word adds value. It is appropriately minimal for a simple get operation.

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

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

For a straightforward single-get tool, the description adequately covers its purpose and parameters. There is no output schema, but return values are implied for a get operation, and the tool's simplicity reduces the need for further detail.

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

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

The input schema already has 100% parameter coverage with clear descriptions for appId and buildId. The description restates that buildId can be a build id or version/build number, adding no new information beyond the schema, so baseline 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states that the tool gets a single build by its App Store Connect build id or version/build number, providing a specific verb and resource. It distinguishes itself from sibling tools like asc_builds_list and asc_build_latest by emphasizing 'single build.'

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

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

The description gives clear context for when to use the tool (when fetching a specific build) but does not explicitly mention alternatives or when not to use it. It implies a single-build lookup, which is sufficient for most scenarios.

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