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

Annotations already declare readOnlyHint, idempotentHint and destructiveHint=false, so the safety profile is covered. The description earns credit by adding non-obvious behavior: reading notifications here does NOT mark them read or clear the badge on Quora, and results come newest-first. It stops short of noting rate limits or result-size expectations, which keeps it below a 5.

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?

Three short sentences, front-loaded with what the tool returns and immediately followed by the important non-mutating side-effect caveat and pagination hint. The phrase 'newest first' appears twice (once in the opening clause, once in the second sentence), a small redundancy that keeps it from 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 no output schema, the description carries the burden of describing returns, and it does reasonably: each item includes what happened, who did it, and the link, plus a next_cursor for paging. Ordering and read-state behavior are covered; only finer return details (badge counts, total counts, exact item shape) are omitted, which is acceptable for a simple read 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 coverage is 100%, with both limit (1-50, default 20) and cursor already documented in the schema. The description's pagination note largely restates the schema's 'next_cursor from the previous call' and it never mentions limit, so it adds little meaning beyond structured fields – the baseline 3 applies.

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 names a specific verb and resource ('Lists the notifications'), scopes it to 'the signed-in account', and enumerates the notification types (answers, upvotes, follows, Space invites). No sibling tool covers notifications, so the agent can immediately tell this apart from list_my_answers, list_answer_requests, and similar list tools.

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 clear context for when to reach for this tool (checking what happened on the signed-in Quora account) and covers the pagination loop with 'Pass next_cursor back as cursor for the next page'. There are no competing alternatives to exclude, so the absence of explicit when-not-to-use guidance is a minor gap rather than a real one.

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