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

Annotations already declare readOnly=true and idempotent=true, so the description only needs to add context. It adds the licensed-only scope and the 'pointers' return concept, but does not disclose behavior for invalid or unlicensed presentation IDs. No contradiction with annotations.

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 that states the resource, the licensed-only restriction, and the identifier scope 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 one-parameter read-only tool with an output schema and safe annotations, the description is largely complete. The only residual gap is the lack of an explicit mention of what to do when the presentation is not licensed, but this is a minor omission given the tool's simplicity.

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 schema provides only a string type for presentation_id with no description, and schema coverage is 0%. The description does add meaning by tying the parameter to a licensed presentation with US NDC, CA DIN, or EU EMA number, but it still leaves the exact accepted format or identifier type implicit.

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 identifies the resource ('label and indication pointers') and a key constraint ('licensed presentation only') with recognizable identifiers, and the title supplies the 'get' verb. It is clear enough to select, though it does not explicitly differentiate itself from siblings like get_safety_label.

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 word 'only' conveys that this tool is restricted to licensed presentations and thereby implies when to use it, but no alternatives or exclusions are named. Unlike a strong definition it does not tell the agent what to use for unlicensed or non-approved products.

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