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

Annotations already declare readOnlyHint=true, openWorldHint=false and destructiveHint=false, so safety is covered. The description adds the useful detail of what data comes back (including a purchase URL), but says nothing about caching, freshness, or whether the offer varies by locale beyond the lang param.

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?

One compact sentence with no filler and the identifying details front-loaded. It loses a point only because it is a sentence fragment that never states the operation explicitly.

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?

With no output schema, the description does the right thing by enumerating the returned fields, which is enough to know what comes back. However, for a tool whose sibling set includes several license/renewal tools, it omits the routing context an agent needs to pick it correctly.

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?

With a single parameter at 100% schema description coverage, the schema already fully documents `lang` (enum en/es, default en). The description adds no parameter guidance, e.g. that the course name and prices are returned localized, so 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 names the specific resource and enumerates its fields (course name, hours, TDLR course number, prices, purchase page), which clearly distinguishes it from siblings like get_renewal_path and lookup_license. It is written as a noun phrase fragment rather than a verb+resource statement, so the action is only implied by the tool name.

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?

There is no statement of when to call this tool versus get_renewal_path or lookup_license, no mention of prerequisites, and no exclusions. An agent must infer usage from the field list alone.

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