TDQS

A4/5.0
Behavior3/5

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

Annotations already declare destructiveHint=true, idempotentHint=true and openWorldHint=true, so the safety profile is known. The description's 'This action is permanent' reinforces destructiveness but is largely redundant, and it never mentions the idempotent behavior or what else (items, submissions) is removed with the quiz.

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

Conciseness5/5

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

Three short sentences, front-loaded with the action and resource, then the permanence warning, then the parameter caveat. Every sentence earns its place with no filler.

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?

For a destructive tool with no output schema, the description covers what is deleted, that it is permanent, and which ID to supply. It could still note required permissions or side effects (e.g. associated items/submissions), but nothing essential for a correct call 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 both parameters are already documented, but the description adds genuine disambiguation by warning to pass assignment_id rather than quiz_id — a real trap given the sibling quiz tools. It does not clarify the course_id vs assignment_id relationship beyond that.

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 (Delete) and a precise resource (New Quiz (LTI) in a Canvas course), and the '(LTI)' qualifier plus the assignment_id note clearly separate it from the classic-quiz sibling delete_quiz and from delete_new_quiz_item. An agent can identify the tool without opening any schema.

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

Usage Guidelines3/5

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

Usage is implied by naming the resource type, and the 'Use assignment_id (not quiz_id)' note helps route between similar deletion tools. However, it never explicitly says when to choose this over delete_quiz or delete_new_quiz_item, nor what prerequisites (role/permission) apply.

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