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

Annotations already declare this as read-only, idempotent, non-destructive, and closed-world. The description adds non-obvious behavioral context: the enquiry figures cover the entire site within the page's live window, not only enquiries attributable to this ad. It does not mention rate limits or error behavior, but the annotations cover the safety profile.

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 tightly written sentence with the returned fields front-loaded and a parenthetical that earns its place by clarifying the enquiry scope. There is no redundant restatement of the title or annotations.

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?

Because there is no output schema, the description appropriately summarizes what the call returns and clarifies the important enquiry aggregation window. It is nearly complete for a simple read-by-id tool; only minor details such as not-found behavior are left implicit.

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%, and the schema already explains that the required id comes from soclo_ad_pages_list or a create result. The description does not add any further meaning about the id parameter, so the baseline 3 applies.

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 clearly states it retrieves a single ad page and enumerates the returned content (words, state, link, clicks, enquiries). It distinguishes itself from list-style siblings by saying "One ad page," though it does not explicitly mention alternatives like soclo_ad_pages_list.

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 singular scope, but the description does not say when to use this versus soclo_ad_pages_list or when a specific page should be fetched rather than previewed or edited. No explicit when-not guidance is provided.

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