add_question_to_quiz

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

No annotations are provided, so the description must bear the full burden. It states 'Add an existing question' implying mutation, but does not disclose effects like duplication handling, permissions required, or impact on quiz total marks. The description lacks sufficient behavioral detail.

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 very concise, with a clear one-line summary followed by structured parameter descriptions. No extraneous information, every sentence serves a purpose.

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?

Important missing context: what happens if the question is already in the quiz (duplicate/ignore/overwrite)? Does adding a question adjust the quiz's total marks? Despite an output schema existing, the description lacks edge-case behavior and side effects.

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 Args section adds meaning beyond the input schema by explaining that 'quiz' is a slug, 'question' is the LMS question name, and 'marks' has a default of 1. This compensates for the 0% schema description coverage. However, the format for 'question' (e.g., name vs ID) is not specified.

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 states the action 'Add an existing question to a quiz', using a specific verb and resource. This distinguishes it from sibling tools like create_question (which creates a new question) and other quiz operations.

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?

No guidance on when to use this tool versus alternatives, such as when to add an existing question vs creating a new one. No prerequisites or context for using the tool are provided.

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