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

readOnlyHint=true already establishes the safe-read profile, so the bar is lower; the description goes further by disclosing the returned shape (token, public URL, name, description, visibility, ordered check tokens), which is valuable because no output schema exists. It omits pagination, ordering and authorization scope details, preventing a 5.

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 front-loaded sentence carrying the resource and the return contract, plus a short API reference. No filler, no restatement of the title.

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 no-parameter read tool with no output schema, the enumerated return fields supply most of what an agent needs, and annotations carry the safety profile. Remaining gaps are pagination/response volume, which are minor for this endpoint.

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 per the rubric the baseline is 4; there is no argument surface the description needs to explain. Nothing here adds or detracts from that baseline.

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 (List) and resource (the account's status pages), and enumerates the returned fields, so it is unmistakable against sibling list tools like updown_list_checks or updown_list_recipients. The trailing API mapping (GET /api/status_pages) removes any remaining ambiguity.

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: an agent can infer this is the way to enumerate status pages, but the description gives no explicit when-to-use guidance and names no alternative (e.g., updown_update_status_page for mutations, or when a per-page lookup would be preferred). Adequate for a trivial read-only list, but no routing help.

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