get_build

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

No annotations are provided, so the description must convey behavioral traits. It describes the tool as a read operation ('Get a single...') but does not explicitly state it is read-only, requires authentication, or lacks side effects. Minimal transparency beyond the basic action.

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 a single sentence that front-loads the key information: the action, resource, and what is included. No wasted words.

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 simple getter with one parameter and no output schema, the description is adequate but not thorough. It tells what the tool returns (build and pre-release version) but does not specify the structure or additional attributes. Could benefit from mentioning response format or related resources.

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?

Schema has 1 parameter (build_id) with description 'Build ID'. The tool description adds context by specifying the build is from TestFlight and includes version, but does not add value beyond the schema for the parameter meaning. Baseline 3 due to 100% schema coverage.

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 'Get a single TestFlight build by ID, including its pre-release version.' It specifies the action (get), resource (single TestFlight build), and the scope (by ID, including pre-release version). This distinguishes it from sibling tools like list_builds (list) and get_app (different resource).

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 implies usage when you need details of a specific build, but does not explicitly state when to use this tool versus alternatives like list_builds or search. No guidance on prerequisites or when not to use it.

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