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

Annotations already disclose read-only, idempotent, non-destructive, closed-world behavior. The description adds useful context about honoring sensitive-content preferences and using searchAfter to continue pagination, though it does not mention auth requirements or rate limits.

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 three sentences and front-loads the primary purpose before pagination details. However, the size default/clamp sentence duplicates schema text and could be trimmed.

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-value details are not required. The description covers purpose, language context, sensitive-content behavior, and pagination continuation, which is sufficient for a read-only listing tool, though it omits ordering or scope details.

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 67%. The size behavior is repeated almost verbatim from the schema, and the searchAfter note largely restates the schema's JSON-string requirement while adding the continuation purpose. The description adds some value but does not fully compensate for the remaining schema gaps.

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 verb and resource: list notification inbox payloads and listing snapshots. It is clear what the tool retrieves, though it does not explicitly contrast itself with sibling tools such as deleteNotification or updateNotificationSeen.

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 implied by 'notification inbox' and the pagination instruction, but the description does not state when to use this tool instead of sibling notification tools. No explicit exclusions or alternatives are provided.

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