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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds only a light note that results are 'structured quiz cards' and that the slug is host-free; it says nothing about pagination, result count, or freshness. With annotations carrying the safety burden this is adequate but thin.

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?

Two sentences, no filler, with the primary purpose front-loaded and the input requirement immediately following. Nothing needs to be trimmed.

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?

An output schema exists and annotations cover safety, so the description need not explain return values or permissions. It covers what the tool does and where the required input comes from, which is sufficient for a single-parameter read tool, though the relationship to the sibling sportskeeda_quiz tool remains unstated.

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?

Schema description coverage is 100% and already enumerates documented category values, so the baseline is 3. The description goes one step further by specifying the slug must be host-free, adding a real constraint beyond the schema's list of examples.

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 states a specific verb and resource ('List structured quiz cards'), plus the scope ('in a current Sportskeeda quiz category'). It names the sibling sportskeeda_quiz_categories as the source of the slug, which helps route the agent away from the categories tool itself, though it never explicitly contrasts with sportskeeda_quiz (the singular detail tool).

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?

It gives a clear workflow precondition: pass a host-free slug that was returned by sportskeeda_quiz_categories, which implies calling that tool first. There are no explicit when-not conditions or identity with alternative tools beyond that single pointer.

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