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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the description correctly aligns with 'Read'. It adds valuable context not in annotations: the tool requires no editToken and is specifically for post-OAuth management of durable websites, which gives agents insight into auth and workflow context.

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 two sentences, front-loading the core action ('Read a claimed account page') and then giving usage context. No redundant or filler content, every sentence 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?

With only one parameter, an output schema present, and strong annotations, the description sufficiently covers the tool's purpose and usage. It explains the key behavioral nuance (no editToken needed) and when to apply it, making it complete for this simple tool.

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 input schema has full coverage (100%) for the single pageId parameter, including its type and format. The description does not add any additional meaning about the parameter itself, so baseline 3 is appropriate.

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 uses a specific verb 'Read' and identifies the resource as 'a claimed account page', explicitly distinguishing it from other page operations by noting it works 'without requiring an editToken'. This clearly differentiates it from sibling tools like page.get or page.claim, which have different purposes.

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?

Provides clear guidance on when to use: 'Use after OAuth when the user wants to manage a durable website.' It implies this is for post-auth management scenarios, but does not explicitly name alternatives or state when not to use it, leaving some ambiguity compared to directly naming sibling tools.

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