get_unconfirmed_subscribers

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

No annotations are provided, so the description carries the full burden. It states 'get' indicating a read operation but lacks details on permissions, rate limits, pagination behavior (e.g., sorting, max page size), or error conditions. Minimal behavioral context.

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, efficient sentence that front-loads the verb and resource. Every word contributes meaning with no redundancy.

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 paginated list with 3 parameters and no output schema, the description covers the core functionality. However, it misses context such as the requirement for a valid list_id, whether the list must exist, or any default sorting. Adequate but not fully complete.

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 parameters list_id, page, and page_size adequately described. The description reinforces pagination via 'paginated list' but adds no extra meaning beyond the schema. 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 clearly states the action 'Get', the resource 'unconfirmed subscribers', and the scope 'for a list'. It distinguishes itself from sibling tools like get_active_subscribers or get_unsubscribed_subscribers by specifying 'unconfirmed'.

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 for retrieving unconfirmed subscribers but provides no explicit guidance on when to use this tool versus alternatives like get_subscriber or get_active_subscribers. No exclusions or context are provided.

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