app_store_versions__build__set

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

Annotations already indicate readOnlyHint=false, idempotentHint=true, and destructiveHint=true, covering the safety profile. The description adds the endpoint and 'RELEASE-level write' context, but does not detail behavior like replacing existing links or required build states, so it stays at a 3.

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?

Two concise sentences, with the endpoint provided and no filler. The action is front-loaded and every word contributes useful information.

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?

With clear annotations and a complete schema, the description is adequate for this simple relationship-update operation. It could mention the response or error conditions, but given no output schema and low complexity, a 4 is appropriate.

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 coverage is 100%, with descriptions for both id ('ID from the matching list call.') and body ('JSON:API request body...'). The description adds no additional parameter semantics, earning the baseline 3.

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 uses a specific verb ('Set') and identifies the exact resource ('build linked to an App Store version'), clearly distinguishing it from related tools like app_store_versions__build__get and builds__app_store_version__set. It also includes the REST endpoint for additional precision.

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 conveys a clear use case (linking a build to an App Store version) and labels it as a 'RELEASE-level write', which implies when it should be used. However, it does not explicitly name alternatives or exclusions, so it falls short of a 5.

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