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

Annotations already declare readOnly=false, idempotent=false, destructive=false, openWorld=false, and the description adds genuine behavior beyond them: the written value is propagated both into the integration and into the quiz version, from which the renderer reads it. It does not, however, warn that delete removes the integration irreversibly, which would be useful for a tool whose annotation marks destructiveHint=false despite a 'delete' action.

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?

Three sentences, front-loaded with the resource and the operations, then a rationale and a side-effect note. Mostly earns its length, though the 'nothing foreign needs to be entered' clause is filler relative to invocation.

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 6-parameter, 3-required configuration tool with no output schema and adequate annotations, the description covers all five actions and the persistence semantics of saved values. It stops short of stating permission requirements or what the show action returns, but the essentials for correct invocation are present.

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 the schema already documents every enum value, the counter max length, and the version/webvisor conditional usage. The description only adds the passing remark that counter values are non-secret and that the value is persisted, which is marginal over the schema baseline.

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 names a specific resource (quiz analytics counters/pixels) and enumerates concrete operations — show state, set counter number, enable, disable, remove — which map onto the action enum. It is clearly distinguishable from most siblings, though it never contrasts itself with the closely related get_quiz_integrations.

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?

There is no explicit when-to-use guidance, no prerequisites, and no routing away from alternatives such as get_quiz_integrations. The sentence about the counter number not being a secret is reassurance for the caller, not usage guidance.

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