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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is fully covered. The description adds that results are links paired with purpose text, but says nothing about result size, ordering, or freshness — meaningful for a whole-site index that could be long.

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 guidance sentence is well placed at the end, but the first sentence is a long comma-chained enumeration of roughly twenty content areas that reads like site copy rather than tool documentation. A shorter summary of coverage would convey the same scope with far less noise.

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, read-only directory with no output schema, the description supplies what an agent needs: scope of coverage, shape of the return (links plus purpose), and a routing hint. Only the absence of any note on result volume keeps it from being fully complete.

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 tool takes zero parameters and the schema is empty, so there is no parameter semantics to explain; the baseline of 4 applies. The description does not mislead about inputs.

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 clear resource — an index of every area of the MCC Solutions site with its link and purpose — and enumerates the covered domains (notary, apostille, store, datasets, Spanish/Portuguese/Creole pages). It is distinguishable from narrow siblings like search_store or read_page, though it never names them explicitly.

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?

"Start here when unsure where something is" gives clear positive guidance on when to reach for this tool. It stops short of stating when not to use it (e.g., go straight to a specific tool like apostille_route or online_notarization_info when the target is already known).

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