batch_get_subscriptions

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

No annotations are provided, so the description carries the burden of disclosing behavioral traits. It indicates a read-only operation ('Get') and batch behavior ('at once'), but does not disclose error handling, partial failures, permissions, or rate limits. This is minimal but not misleading.

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, focused sentence that avoids unnecessary words. It front-loads the action and object, making it easy to parse.

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 tool is simple with full schema coverage and an output schema, so the description's brevity is partially justified. However, with no annotations and no usage guidance, the description leaves some gaps around when to use this tool and how it handles missing or invalid IDs.

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?

The input schema already documents both parameters (package_name and product_ids) with descriptions, and coverage is 100%. The description adds the batch context ('multiple', 'at once') but no additional parameter-level semantics, so a baseline score 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's function: retrieving details for multiple subscription products in a single call. The verb 'Get' and resource 'subscription products' are explicit, and 'at once' distinguishes it from single-fetch alternatives like get_subscription.

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 batch usage with 'multiple' and 'at once', but does not explicitly state when to prefer this over alternatives like get_subscription or list_subscriptions. It lacks when-not-to-use guidance or named sibling alternatives.

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