Read-onlyIdempotent

What The Dutch Directory covers: listing counts by type, the Verified Pro count, doctrine and endpoint URLs. Call it when you need to know the scope of the directory before searching.

A4.1/5.0

Behavior4/5

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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so safety is covered. The description adds the useful fact that the response is a content/payload overview (counts, doctrine, endpoint URLs), which annotations do not convey. It stops short of describing response shape or stability guarantees.

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?

Two sentences, zero filler, and the payload overview is front-loaded ahead of the call-when guidance. Every clause earns its place.

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?

With no parameters, no output schema, and full annotation coverage, the description is the sole source of return-value information and it does name the returned content (counts by type, Verified Pro count, doctrine, endpoint URLs). It could say more about shape or freshness, but it is sufficient for a zero-arg read tool.

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?

The tool takes zero parameters, so there is nothing to document and the baseline is 4. The description correctly adds no fictitious parameter guidance.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb+resource: it returns what the directory covers, namely listing counts by type, the Verified Pro count, doctrine, and endpoint URLs. That is a concrete payload description that separates it from search/stat siblings. It lacks only explicit sibling differentiation in wording.

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

Usage Guidelines4/5

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

It gives a clear trigger: 'Call it when you need to know the scope of the directory before searching.' This establishes the when and implies the relationship to tdd_search. It does not name when not to use it or list alternatives beyond the search reference.

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