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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is fully covered. The description adds one useful behavioral fact — the content is publicly readable ('pages anyone may read') — but says nothing about what the returned sample payload looks like or how it is structured.

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?

It is a single short sentence, so nothing is bloated, but the colon-and-slash construction ('poor SEO / AEO: what a buyer gets') is awkward and buries the key point. The most informative clause, 'what a buyer gets,' arrives late and is not front-loaded.

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-argument, read-only tool with full annotation coverage and no output schema, the description only needs to say what content comes back. It gestures at three artifacts (lead, idea report, website) but leaves their nature and relationship ambiguous, which is the minimum-viable level rather than 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, so there is nothing for the description to disambiguate; baseline 4 applies. No parameter text is needed or expected.

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 is a noun phrase ('The free sample lead, idea report and website...') rather than a verb+resource statement, so it never says what the tool actually does — presumably returns sample/demo content. The phrase 'what a buyer gets, on pages anyone may read' hints at sample artifacts, but an agent cannot confidently distinguish this from the sibling search tools without guessing.

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?

There is no explicit when-to-use guidance and no sibling is named, even though get_website_gap_score, search_problems, and search_website_gaps exist and could be confused with it. 'What a buyer gets' vaguely implies a demo/preview use case, but nothing states when to call this instead of the search tools.

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