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

Adds real context beyond annotations: it is rate-limited and metered, the output is 'READY TO APPLY' text, and grounding draws on crawl + search data when available. Annotations cover the safety profile (readOnly true, destructive false), and nothing here contradicts them since the tool generates rather than writes.

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?

Front-loaded with purpose in the first clause, then application guidance. The Wix/WordPress sentence is long and dense, but each sentence carries actionable information rather than filler.

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?

No output schema exists, and the description compensates by explaining that the returned suggested text is ready to apply and how to apply it per platform. Combined with the metering/rate-limit note, an agent has enough to call and act on this correctly; only result shape details remain unspecified.

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 100%, so the schema already documents url, type, query, and context, making 3 the baseline. The description echoes the four field types and the grounding on crawl/search data, but adds no format, length, or output constraints beyond that.

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?

States a specific verb (generate) and resource (improved page title, meta description, heading, section outline) tied to a URL. It implicitly separates itself from wp_update_page/wp_patch_page by casting those as the application path rather than the generation step, though it never names a sibling that does the same job.

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?

Clear context: use when you need suggested text for one of four field types, and explicit downstream routing (apply via wp_update_page/wp_patch_page on WordPress; via the user's Wix MCP where API-editable; hand text over for editor-only fields). It does not say when NOT to use it versus near-neighbors like assist_writing_fix, review_writing, or score_content_draft.

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