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

Adds real context beyond the annotations: it discloses the data provenance (store listing fields), the precedence rule that user answers override them, and that save=true publishes while save=false is review-only. It does not state that publishing overwrites an existing page or whether that is reversible, which matters given destructiveHint=true.

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-loads what the tool does in the first clause and keeps every sentence informational; nothing is filler. However, the middle sentence packs provenance, a long field list, and the override rule into one dense run-on that is harder to parse than it needs to be.

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 4-parameter tool with a large nested answers object and no output schema, the description covers template scope, input provenance, override precedence, the review path, and the pre-generation interview. The remaining gap (what a saved page returns) is minor for a page-generation tool whose result is the page itself.

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 100%, so the schema already documents site, page, save, and the answers object, establishing a baseline of 3. The description adds one genuinely new semantic rule ('your answers override them' for store-listing-derived values) plus the pre-generation question list, but offers no syntax or format detail the schema lacks.

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?

Names a specific verb and resource ('Make one of your site's pages from AppPage.net's templates') and enumerates the page genres the enum offers. It also explicitly distinguishes itself from the sibling set_page, so an agent can route without opening either schema.

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?

Gives an explicit preference rule ('Prefer this to writing a page yourself with set_page'), a pre-flight instruction to ask the user about things the store listing can't supply, and a review-only path via save=false. When-to-use, when-to-ask, and the alternative are all stated.

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