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

No annotations are provided, so the description must carry the behavioral transparency burden. It does disclose a key constraint: this tool works only for licensed presentations belanja and indicates that the output is pointers rather than full label content. But it does not describe behavior for unlicensed or invalid presentations, authentication needs, or error handling, so transparency is partial.

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 one short sentence with no filler. The core resource ('Label and indication pointers') is front-loaded, followed by the key scope constraint ('licensed presentation only'). Every word adds information.

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 single-parameter lookup tool with an output schema, the description is minimally adequate: it names the resource, constrains scope, and hints at identifier formats. However, it leaves the mapping between presentation_id and the parenthetical identifiers implicithare, and it gives no usage guidance relative to siblings. This is sufficient for a simple tool but not richly complete.

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 no description for presentation_id, so the description must compensate. It adds meaning by listing the accepted identifier types (US package NDC, CA DIN, EU EMA number), which presumably map to presentation_id. However, it does not explicitly state that presentation_id should be one of these values or explain formatting, so compensation is incomplete.

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 identifies the resource ('label and indication pointers') and the target scope ('licensed presentation only'), and it distinguishes itself from related tools like get_safety_label by focusing on licensed presentations with NDC/DIN/EMA identifiers. It lacks an explicit verb, but the title 'Get Label And Indication' supplies the action. Minor ambiguity remains in what 'pointers' means.

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 when to use the tool: when you have a licensed presentation identified by a US package NDC, CA DIN, or EU EMA number. However, it does not explicitly state when not to use it or compare it to sibling tools like get_safety_label or get_item. The guidance is present only by inference.

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