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

Annotations already signal readOnly, idempotent, non-destructive behavior; the description adds the price and scope but no disclosure of what happens when invoked, output format, or call semantics. Even with annotations lowering the bar, this is minimal value.

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 description is concise and front-loaded: it gives the action and then the price in a single additional sentence. It earns its place and is easy to scan, though it is too sparse even for the purpose dimension.

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?

With no output schema and only one parameter, the description should carry full weight for agents. It does not state what the tool returns, whether the text must be plain text vs. HTML, or what an audit result looks like. It gives the price but little else.

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?

Schema coverage is 0%; the description does not explicitly explain the 'text' parameter beyond implying that it is the landing-page copy to audit. With one obvious parameter, some meaning is inferable, but the description could have explicitly stated what to supply and any constraints.

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 ('Audit') and resource ('short landing-page copy') and lists the exact audit dimensions (clarity, outcome, call-to-action, readable length). It is clear, though it does not explicitly distinguish itself from sibling tools like site-copy-review, so it misses full differentiation.

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?

It implies when to use the tool (when a short landing page needs audit) but provides no when-not-to-use guidance, no prerequisites, and no comparison with siblings like site-copy-review or custom-checklist. That is a real gap.

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