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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds organizational context about approval requirements that may affect what appears in the inbox, which is useful but does not describe pagination behavior, ordering, or what happens with the id filter.

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 first sentence is front-loaded and efficient. The second sentence is brief but its relevance to invoking this tool is unclear and reads as unrelated policy boilerplate, slightly muddying rather than sharpening the definition.

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 and annotations cover the safety profile, so return values need not be described. However, with four undocumented parameters and no guidance on filtering/pagination semantics, the description leaves real gaps for a list 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?

Schema description coverage is 0% and all four parameters (id, limit, offset, search) are undocumented in both schema and description. The description says nothing about whether id fetches a single notification, how limit/offset paginate, or what search matches, so it fails to compensate for the coverage gap.

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 your own notification inbox') with a scope qualifier ('your own') that separates it from org-wide or approval-request listings. It does not explicitly name the nearest siblings (mark_notification_read, dismiss_notification, list_pending_approval_requests), so differentiation is only implicit.

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?

There is no statement of when to call this versus alternatives like list_pending_approval_requests or mark_all_notifications_read. The second sentence discusses approval configuration policy rather than telling the agent when this tool is the right choice.

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