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

Annotations already declare readOnly, idempotent, and non-destructive behavior, so the safety profile is covered. The description adds genuinely new context beyond the annotations: that no editToken is required, which is an authorization fact the schema and annotations do not express.

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?

Two short sentences with the read/no-editToken fact front-loaded, and no wasted words. The closing phrase 'manage a durable website' is somewhat abstract and could be tighter, but overall it is efficient.

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?

An output schema exists, so return values need not be described. For a single-parameter read tool with full annotation coverage, the description supplies the authorization context and the usage trigger, leaving only the sibling comparison unaddressed.

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% and the single pageId parameter is fully documented in the schema, including its uuid format. The description adds nothing about the parameter, so the baseline of 3 applies when structured fields carry the load.

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 ('Read a claimed account page') and adds a distinguishing constraint ('without requiring an editToken') that separates it from the editToken-gated siblings like page_get. The title 'Manage Claimed Page' and the name 'account_page_manage' imply mutation, but the description correctly clarifies it is a read.

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?

Gives a situational trigger ('Use after OAuth when the user wants to manage a durable website') but never names the alternative tools it should be chosen over, such as page_get or account_pages_list. The editToken remark implies a contrast with page_get, but the routing decision is left to inference.

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