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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false, and openWorldHint=false, so the safety profile is fully covered by structured data. The description adds genuine scope context — that results are limited to the authenticated organization's public pages — but says nothing about pagination, ordering, or result size.

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?

One short sentence with no filler, and the key scope constraint arrives immediately. It is appropriately sized for a zero-argument list tool, though it leaves nothing in reserve for any secondary guidance.

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 parameterless read operation with a full annotation set and no output schema, the description gives enough to call it correctly and to know what population it covers. The only shortfall is that no return shape is hinted at, which is a minor gap given the simplicity of the operation.

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?

The tool takes zero parameters, so the 4 baseline applies. The description correctly implies no filtering arguments exist, avoiding any misleading expectation of query options.

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 and resource ("List ... status pages") plus scope qualifiers ("public-facing", "owned by the authenticated organization"), which separates it from the sibling vs_status_pages_get. It does not explicitly distinguish itself from vs_status_page_groups_list or vs_subpages_list, so a 5 isn't warranted.

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 only implied: the fact that it is the unfiltered list with no parameters suggests when to reach for it, and the "public-facing" phrasing hints that internal pages are excluded. No explicit when-to-use statement or named alternative (e.g., use vs_status_pages_get when you already have an ID) is given.

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