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

With no annotations, the description carries the behavioral burden. It usefully discloses that the tool performs a live homepage fetch and reports three specific conditions, which implies read-only behavior. However, it does not describe failure modes, rate limits, permission requirements, or what happens when the domain is unreachable.

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?

A single, front-loaded sentence with no filler. It efficiently communicates the fetch behavior and the three reported checks.

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 simple one-parameter read-only tool with no output schema, the description adequately explains the returned signals in natural language. The main gap is the undocumented domain format, but overall it is complete enough to invoke correctly.

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?

There is one required parameter, domain, with 0% schema description coverage. The description does not clarify whether the domain should be a bare hostname, a full URL, or include a protocol, leaving a notable ambiguity for the only input.

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 specific action (fetches the live homepage) and enumerates the exact signals reported: Shortbread tag presence, leftover Cookiebot tag, and claim status. It is clear what the tool does, though it does not explicitly distinguish itself from sibling tools like scan_site.

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?

Usage is implied by the checks performed—it is the tool for verifying live installation status—but there is no explicit when-to-use guidance, no mention of alternatives, and no stated prerequisites such as domain format or whether the domain must already be provisioned.

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