Verify Quiz Answer

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It discloses the side effects: updating streak, XP, and badges, plus speaking feedback. This gives the agent a clear sense of what will change, though it does not mention reversibility or any prerequisites.

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 concise, information-dense sentence. It includes the action, target, and side effects without any filler or repetition of the tool name.

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 one-parameter tool with no nested objects and no output schema, the description covers the essential action and effects. It could optionally mention that a quiz must be currently pending, but the phrase 'the most recent active-recall quiz' provides enough contextual framing for correct use.

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 input schema already covers the single parameter with 100% description coverage, explaining that 'answer' is either a letter (A-D) or answer text. The tool description adds no additional parameter meaning beyond what the schema provides, so the baseline score of 3 is appropriate.

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 uses a specific verb ('Evaluate') and names the precise resource ('the learner's answer to the most recent active-recall quiz'). It also lists the tool's effects (streak, XP, badges, feedback), which clearly distinguishes it from the unrelated sibling tools.

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 clearly implies the tool should be used when a learner provides an answer to the most recent active-recall quiz. It does not explicitly name alternatives or exclusion conditions, but the context is clear and the sibling tools are not overlapping in function.

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