A3.6/5.0

Behavior4/5

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

The annotations already establish read-only, idempotent, safe behavior. The description adds useful context beyond them by noting the information is public and requires no sign-in, which removes authentication ambiguity for the agent. It does not contradict any annotation.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is two compact sentences with no filler, and it front-loads the content scope before the authentication note. It is appropriately sized for an informational tool, though the second sentence is a terse fragment rather than a fully structured statement.

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, rich annotations, and an output schema present, the description only needs to convey the tool's informational scope and any access constraints. It does both, but it omits any signal about how this overview differs from adjacent informational siblings like how_it_works or get_faq.

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, and the schema description coverage is 100%. Per the rubric, a zero-parameter tool starts at a baseline of 4 because there are no parameter semantics for the description to clarify.

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 clearly identifies an informational overview tool, enumerating the topics it covers (product purpose, audience, report value, starting point). It does not, however, distinguish itself from overlapping siblings such as how_it_works, get_faq, or get_pricing, so it falls short of a 5.

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

Usage Guidelines2/5

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

There is no explicit guidance on when to use this tool versus alternatives like how_it_works or get_faq. The phrases 'where to start' and 'Public information; needs no sign-in' hint at intended audience and prerequisites, but the description never states when this tool is the right choice over its siblings.

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