Check MaxPreps connectivity

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

Annotations already declare readOnlyHint and openWorldHint, and the description adds useful behavior beyond that: no credentials required, reports failure rather than throwing, and probes a real data route so a pass indicates tool functionality. There is no contradiction with annotations.

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?

Four sentences with no filler: the core purpose and pass/fail meaning come first, followed by behavioral caveats. The final 'Read-only' is slightly redundant with the annotation but harmless and brief.

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 zero-parameter healthcheck, the description covers purpose, prerequisite context, failure behavior, and what a pass means for the other tools. The main gap is that it does not spell out the exact return payload, but no output schema exists and pass/fail semantics are reasonably clear.

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 schema has zero parameters, so there are no parameter semantics to cover. The description still adds useful context by stating that no credentials are required by the server, which is relevant for invocation. This matches the baseline-4 expectation for zero-parameter tools.

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 verb and resource: it verifies MaxPreps reachability and that the site build id resolves, then probes a real data route. This clearly distinguishes it from the sibling data-fetching tools, which all retrieve content rather than check connectivity.

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 implies when to use it: as a preflight check before relying on data routes, since 'a pass means tools will work.' It does not explicitly state 'use when data tools fail' or name alternatives, but the healthcheck role is obvious against the sibling data tools.

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