TDQS

A4.1/5.0
Behavior4/5

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

Annotations already cover the safety profile (readOnly, idempotent, non-destructive, closed-world), and the description adds real context beyond them: the exactly-one-identifier constraint (important since required_parameters is 0), the advisory-only framing, and the caution that co-occurring medicines are not substitutes. It doesn't state what happens when no candidate matches a name.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Three sentences, front-loaded with what is returned before the constraints, and every sentence carries either scope, a disambiguation rule, or a safety boundary. It is dense and runs as a single paragraph, but nothing is redundant.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With an output schema present, return values needn't be described, and the description instead covers the things the schema and annotations cannot: identifier exclusivity, advisory-only use, and the non-equivalence of co-listed medicines. Nothing an agent needs to invoke it correctly is missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the baseline would be 3, but the description adds the mutual-exclusivity rule ('given exactly one of') that the schema does not encode via oneOf, plus name resolution to 'one CIS or a list of candidates'. Format details (8-digit, 13-digit barcode) are left to the schema, appropriately.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description names a concrete resource (boxes of a medicine in the BDPM, plus prescription/dispensing conditions and current ANSM safety information) and the exact access keys (CIS, CIP13, or name), which lets an agent separate it from a name-based search tool. It stops short of naming search_medicine or any sibling, so routing among lookups is inferred rather than stated.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It gives an explicit prohibition — never use for substitute/alternative/dosage-change/stopping-treatment advice — and clarifies that other medicines in results are not alternatives. What is missing is positive routing guidance: when to pass a name here versus calling search_medicine first.

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