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

With readOnlyHint=true and openWorldHint=false already covering the safety profile, the description still adds real behavioral context: read vs write key changes what is returned, and passwords are never exposed. It does not, however, describe pagination or error behavior.

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?

Three tight sentences, front-loaded with the core concept (who can open the page), then the key-type nuance, then the password caveat. Phrasing like 'is in the answer for a write key only' is slightly compressed but earns its place.

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?

There is no output schema, so the description must convey return contents; it does so partially by specifying the people list with last sign-in times and the key-type gating. The precise response shape is left somewhat vague but the essentials are covered.

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% and the single pageId parameter is already documented as coming from list_pages, so the schema carries the load. The description adds no syntax, format, or sourcing detail beyond it, which is the expected 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?

The description states a specific resource and its conceptual output: a page's access mode (public, password-protected, private to people/email domains). It is clear what the tool returns, though it never explicitly names a sibling tool (e.g., list_pages) to differentiate itself from them.

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 infers you call this to audit who can open a given page. There is no explicit when-to-use, when-not-to-use, or named alternative, so routing must be inferred from the tool name and the sibling set.

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