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

The annotations already establish that this is a safe, read-only, idempotent lookup. The description adds useful behavioral context by explaining that "personal" covers non-commercial license types while "business" returns rate-card dimensions such as medium, category, territory, and term, and that track_id adds exact prices and licensability. It does not discuss pagination or output shape, but the annotations carry the safety profile.

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 front-loaded with the core action and remains tightly structured. Each sentence adds useful information about license types, track_id behavior, or the next step with initiate_license, with no filler.

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 read-only lookup with one optional parameter and no output schema, the description gives enough context about what is returned: personal license types, business rate-card dimensions, and track-specific pricing/licensability. It also connects the result to initiate_license, making the workflow clear.

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%, so the baseline would be 3. The description adds meaning beyond the schema by explaining that track_id yields that track's exact prices and whether it can be licensed, not just that it adds price to every option.

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 uses a specific verb and resource: "List license options with prices in USD." It also clarifies the two option families (personal vs. business) and ties the output to the sibling initiate_license, so an agent can distinguish this from search/catalog tools.

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?

It states the key usage condition for track_id: pass it to get that track's exact prices and licensability. It also says to use the chosen options with initiate_license. There is no explicit when-not-to-use guidance or comparison against other sizing/verification siblings, so it falls short of a 5.

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