KinToolkit: Medicine Dosage Calculator Label References for Children and Infants

Read a complete medicine question guide

get_question_guide

Read the full published educational guide by exact public guide_id from list_question_guides. Markdown includes every paragraph, table, product/formulation distinction, source and safety limitation, identical to the website Markdown. updated is a content date, not clinical review. Chewables and Claritin remain reference-only and cannot be used with get_label_directions. No patient inputs; operational telemetry excludes arguments and results.

TDQS

A3.7/5.0

Behavior2/5

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

The description discloses a lot that annotations do not: output is full website-identical Markdown including tables, formulation distinctions, sources and safety limits; 'updated' is a content date, not a clinical review date. However, it declares a pure read operation while the annotations set readOnlyHint=false, an inconsistency the agent must reconcile (the mismatch is conservative rather than dangerous, but it is still a contradiction).

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?

Purpose and identifier source are front-loaded in the first sentence, with caveats after. The closing line about telemetry and 'no patient inputs' is meta-information about operations rather than about invoking the tool, so it dilutes an otherwise tight definition.

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

Completeness4/5

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

With an output schema present, the description needn't describe return values, yet it usefully characterizes them as complete Markdown and qualifies the 'updated' field. What's missing is error behavior for an invalid or unknown guide_id, which matters for an exact-match lookup.

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

Parameters3/5

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

Schema description coverage is 0%, so the description must carry the parameter, and it does partially: 'exact public guide_id' plus the requirement to source it from list_question_guides tells the agent the value is a canonical key, not free text. It adds nothing about how to choose among the 33 enum values or what happens on a mismatched ID, so it only partly compensates.

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

Purpose5/5

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

States a specific verb and resource ('Read the full published educational guide') and pins the lookup key ('by exact public guide_id from list_question_guides'), which cleanly separates it from the listing tool and from get_label_directions. An agent can tell what this returns versus its siblings without opening the schema.

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?

Explicitly routes the agent to list_question_guides to obtain the ID and adds a real exclusion: chewable and Claritin guides are reference-only and 'cannot be used with get_label_directions'. It stops short of stating the positive trigger ('use this when the user asks about a covered topic') but the retrieval path and one boundary are clear.

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