alternative_distribution_domains_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 behavioral burden, and it discloses nothing: no auth/permission requirements, no error behavior for a missing id, no note that this is a read-only fetch. The parenthetical merely duplicates the path.

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?

It is short, but the parenthetical is pure duplication rather than conciseness — the same string is stated twice with zero additional information, so the content is under-specified rather than efficient.

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 no annotations, no output schema, and a bare endpoint string, the definition omits everything an agent needs to call it confidently: return shape, id format, failure modes, and any scoping constraints.

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%, with both id and fields_alternativeDistributionDomains documented in the schema, so the baseline is 3. The description adds nothing beyond the schema but is not misleading.

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 the raw REST path repeated verbatim in parentheses, which restates the tool name rather than explaining purpose in plain language. An agent can infer 'fetch one alternative distribution domain by id' from the path and the sibling alternative_distribution_domains_get_collection, but the definition itself contributes no explanatory content.

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?

No guidance on when to use this tool versus the collection sibling or any other retrieval tool. Nothing about prerequisites, id sourcing, or when-not-to-use is present.

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