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

Annotations already declare readOnlyHint, destructiveHint=false, idempotentHint, and openWorldHint=false. The description adds useful behavioral context by specifying what is explained for each medicine and reinforcing 'Never changes a dose', though it does not describe language handling or output limits.

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 two compact sentences, front-loads the purpose, and lists the expected outputs without filler. The final clause 'Never changes a dose' is short and materially useful.

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 explainer with no output schema, the description adequately enumerates what is returned for each medicine. It still omits the language parameter and does not state informational limits such as not being medical advice, so it is only minimally 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?

Schema description coverage is 0% and there are two parameters. 'Pasted as text' adds some meaning for prescription_text, but the language parameter is never mentioned and no format details are given, so the description does not compensate for the missing schema documentation.

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 resource (a prescription pasted as text) and enumerates concrete outputs: uses, dosing notation interpretation, cautions, and questions to ask. It does not explicitly distinguish itself from siblings such as explain_lab_report, so it falls short of a 5.

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 'prescription pasted as text' implies the input condition under which this tool is used. However, it gives no explicit when-not guidance, prerequisites, or alternatives such as when_to_seek_care, leaving usage largely implied.

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