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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is fully covered elsewhere. The description adds genuinely new behavior: ordering (most recent first), the 404 when Notification Center is disabled, and that batchId returns only 'live' members. That is useful, but it says nothing about the response envelope or how cursor/nextCursor round-trips beyond 'paginate with limit/cursor'.

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?

Front-loaded with the core action and ordering, then filters, then pagination, then the prerequisite/404 caveat — a sensible order. The middle clause enumerating every filter is a run-on that mostly duplicates schema and could be trimmed without loss, keeping it short of a 5.

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 12 optional parameters and no output schema, the description covers invocation adequately: no required params, how to page, mutual exclusions, and the feature-gate failure mode. The remaining omission is what a returned notification contains and how batch member ordering interacts with pagination, which matters given no output schema exists to cover it.

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%, including enum value lists and the severity/minSeverity mutual exclusivity and sort-with-batchId constraint, so the description is largely restating structured data. It does reinforce the constraint pairings in one place, which is convenient, but adds no format, default, or boundary detail the schema lacks. 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?

Opens with a specific verb+resource and scope: 'List notifications for the authenticated user's current team, most recent first.' That is unambiguous about what it returns and the default ordering. It does not, however, name or distinguish itself from nearby siblings such as getNotificationFeed, getNotificationBatch, or getUnreadNotificationCount, leaving the agent to infer which list-shaped tool to pick.

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 concrete usage guidance inside the call: which filters exist, that severity and minSeverity are mutually exclusive, that sort=importance is only valid together with batchId, and how to paginate. It also states the prerequisite (Notification Center feature, 404 otherwise). The gap is that it never says when to prefer this over sibling notification tools such as getNotificationCounts or dismissNotification.

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