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

The annotations already mark the call read-only, idempotent, and non-destructive, and the description adds substantial runtime behavior beyond that: batch grouping semantics, severity filters narrowing batch counts and hiding empty batches, eventual consistency with counts lagging by one page fetch, and a 404 when the feature is disabled. This is excellent behavioral disclosure.

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 dense but well organized: it starts with what the tool returns, then covers item composition, filtering and pagination, batch-count effects, and operational caveats. Every sentence earns its place, and there is no redundant restatement of schema details.

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?

For a tool with no output schema and a complex batch/feed model, the description covers all operationally important aspects: scope, ordering, item types, filters, pagination, batch behavior, eventual consistency, and feature availability. An agent has enough context to select and invoke this tool correctly.

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 already documents most parameters well (75% coverage). The description adds value by summarizing the filter model, making the exact-match vs threshold distinction and mutual exclusivity of severity and minSeverity explicit, and identifying limit/cursor as the pagination mechanism, which the schema leaves undescribed.

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 clearly identifies a concrete action and resource: list the authenticated user's current-team notification feed, most recent activity first, and it explains that items are individual notifications or batches. However, it does not explicitly differentiate itself from closely related siblings like listNotifications, getNotificationBatch, or getNotificationCounts.

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?

The description gives strong contextual guidance: it targets the current team's feed, supports filters and pagination, and warns that the Notification Center feature must be enabled or the call returns 404. It does not explicitly say when to use this tool instead of the sibling notification tools, so it lacks explicit alternative routing.

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