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

Annotations already declare the operation as read-only, non-destructive, and open-world, so the safety profile is covered. The description adds that the tool fetches a page and compares its title/meta description against ranked queries, but it does not disclose auth needs, rate limits, or what happens if the page or query data is unavailable.

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 a single front-loaded sentence with no filler or repetition. It conveys the core action efficiently, even though it omits details covered in other dimensions.

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 read-only page review tool with no output schema, the description explains the core purpose but leaves important input semantics and return expectations unclear. Given three required parameters with zero schema descriptions, more context is needed for an agent to call it confidently.

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 description coverage is 0% and all three parameters are required, but the description does not explain projectId, siteId, or pageUrl. It only says 'a page,' which weakly implies pageUrl but leaves the project/site scoping parameters entirely undocumented.

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 verb and resource: fetching a page and reviewing its title and meta description against the queries it ranks for. This is clear and distinguishable from most sibling tools, but it does not explicitly name or contrast with a related alternative such as inspect_urls.

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?

The description implies the tool is for reviewing a page's search snippet, but it gives no explicit when-to-use guidance, prerequisites, or alternatives. An agent must infer the appropriate context without any stated exclusions or comparison to sibling tools.

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