background_asset_version_external_beta_releases_get_instance

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It reveals only the HTTP verb, from which read-only/safe semantics can be weakly inferred, and says nothing about authentication, error behavior when the id is unknown, or whether include/fields expansion changes the payload. For a zero-annotation tool this is a substantial gap.

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 short but wastes its entire length by printing the same endpoint twice, once bare and once in parentheses. There is no front-loaded purpose statement to benefit from the brevity, so the concision is accidental rather than earned.

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 four-parameter instance-fetch tool with no output schema and no annotations, an agent needs at least a statement of what a backgroundAssetVersionExternalBetaRelease is and what the sparse-fieldset and include options return. None of that is present; the description only names the route.

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 description coverage is 100%, so the schema already documents all four parameters including the required id, the include relationship list, and the two sparse-fieldset options. The description adds nothing beyond the schema, so the 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 is a bare restatement of the HTTP route 'GET /v1/backgroundAssetVersionExternalBetaReleases/{id}', duplicated verbatim in parentheses. It conveys no plain-language statement of what the resource is or what retrieving it yields, and gives no differentiation from near-identical siblings such as background_asset_version_internal_beta_releases_get_instance or background_asset_version_app_store_releases_get_instance. This is effectively a tautology of the tool name.

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?

There is no when-to-use guidance, no prerequisites, and no routing to alternatives. The description never mentions the closely related external-beta-release siblings or explains when an agent should fetch a single external beta release instead of the internal beta or app store release variants. No guidance is better characterized as absent than misleading.

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