alternative_distribution_package_versions__variants__list

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

Annotations already declare readOnlyHint=true and idempotentHint=true, which the description does not contradict. However, the description adds no behavioral context beyond the HTTP path, such as pagination behavior, ordering, or the scope of results. It fails to add value beyond the annotations.

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 extremely concise: a single sentence that states the core action, supplemented by the HTTP path. Every word is necessary, with no extraneous 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?

The description is adequate for a simple list operation but lacks details about the return structure (no output schema), pagination behavior, or any filtering capabilities. Given the complexity (few parameters, read-only), the minimal description leaves gaps for an AI agent, though it is minimally viable.

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 all parameters described in the input schema. The description does not provide additional meaning beyond the schema, such as explaining the difference between 'limit' and 'next_url' for pagination. Baseline of 3 is appropriate.

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 the tool lists variants belonging to an alternative distribution package version, with a specific verb ('List') and resource ('variants'). The HTTP path is included for reference. This distinguishes it from sibling tools like getting a specific variant or listing deltas.

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 context by naming the parent resource ('alternative distribution package version'), but it does not explicitly state when to use this tool vs alternatives, such as when to fetch individual variants or list deltas. No exclusions or alternatives are mentioned.

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