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

With no annotations provided, the description carries the full burden of behavioral disclosure. It clearly reveals the atomic all-or-nothing behavior, hard room limits (200 pages, 6 MB), and the conceptual ceiling that 'a room is a review set, not a host.' It also calls out how pages link together and why the ceiling matters in practice.

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 long but every sentence earns its place: primary behavior first, then when-to-use guidance, then resource limits, then an alternative workflow with a concrete command. The structure front-loads the most decision-relevant information and does not repeat schema content unnecessarily.

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?

Given that there are no annotations and no output schema, the description covers everything an agent needs to decide whether and how to call this tool: what it does, when to use it, when not to use it, what constraints apply, and how pages should relate to each other. Nothing critical is left to inference.

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 baseline is 3, but the description adds meaningful context beyond the schema: it frames pages as an entry page plus linked pages, stresses the atomicity requirement, and clarifies that plain relative hrefs allow mixed formats. This gives an agent a better mental model of how to construct the 'pages' array than the schema alone.

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 action ('Publish a multi-page set') on a specific resource ('into one room') and immediately contrasts it with the sibling share_page by emphasizing atomicity and multi-page scope. An agent can clearly distinguish this tool from share_page without opening the 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?

It explicitly says to use this 'instead of calling share_page N times whenever you have more than one page' and also directs file-based workflows to the uploader alternative. It even provides a ready-to-run command for that alternative, leaving no ambiguity about when this tool is the right choice.

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