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

With destructiveHint=true and readOnlyHint=false, the annotations only signal that something here mutates; the description pinpoints exactly which action mutates ('read does, keeping the first read time') and which does not ('get'). That is the crucial side-effect disclosure the annotations cannot express. It still omits auth requirements, whether acknowledgement is reversible, and any 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?

Two dense sentences with no filler, and the highest-value fact (which action mutates) is front-loaded in the second sentence. The clipped, note-like phrasing reads as slightly fragmentary but wastes nothing.

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 4-parameter tool with 0% schema coverage and no output schema, the description leaves too much open: no mention of pagination via cursor/limit, no description of what a notice record contains, and no coverage of the 'list' action. Adequate only for the narrow get-vs-read decision.

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%, so the description must carry parameter meaning, and it explains only the 'action' enum for two of its three values. The 'id', 'limit', and 'cursor' parameters receive no explanation anywhere, leaving pagination and targeting semantics undocumented.

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 first sentence names the resource concretely (account notices) and enumerates what they cover: pause expiry, unpaid storage, deletion deadlines. The second sentence distinguishes two of the three actions, so an agent knows this is the notice retrieval/acknowledgement tool. It falls short of a clean verb+resource statement for the 'list' action.

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?

It gives a real when-to-use distinction between 'get' (non-mutating) and 'read' (marks as read), which is the most consequential choice for the caller. However, it says nothing about when to use 'list' vs 'get', when paging is needed, or the broader context in which notices matter.

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