List Subscribed SKUs

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

Annotations already establish readOnlyHint, idempotentHint, and destructiveHint false, so the description only needs to add context. It adds tenant scope and the seat availability purpose but does not disclose return format or pagination. This is consistent but not highly enriching.

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?

A single, front-loaded sentence with no filler. It immediately states the action and purpose, making it easy for an agent to parse and understand.

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 zero-parameter, read-only tool with rich annotations, the description is complete enough. It states what is listed and why, and the sibling context clarifies its role. No output schema exists, but the description's simplicity minimizes the need for more detail.

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 tool has zero parameters and 100% schema coverage, so the description has no burden to explain parameters. According to the baseline for 0 params, this scores a 4. The description does not need to add any parameter guidance.

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 'List tenant subscribed SKUs' with a specific verb and resource. Adding 'for license lookup and seat availability' clarifies the purpose and distinguishes it from sibling tools like get_user_license_details or assign_license.

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 phrase 'for license lookup and seat availability' provides clear context on when to use this tool, indicating tenant-level license inventory. It does not explicitly mention alternatives or exclusions, but the use case is well implied given the sibling tools.

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