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

Annotations only supply readOnlyHint=true; the description adds that login is required, that the call is capped at 100 items with no pagination, and that reads are 'heavy' because each item requires audience review. Those limits and the no-pagination constraint materially change how an agent should call it. Return shape is not described, but there is no output schema to compensate.

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?

Dense and front-loaded with no filler, but the semicolon-chained fragments mix routing advice, id semantics, cost warnings, and limits with no hierarchy, and the '登录' opener is a fragment. Compact, but readability suffers.

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?

Covers auth, result cap, absence of pagination, item-id semantics, and the tools to call next – the operational essentials for a single-parameter read tool with no output schema. Not exhaustive about what a notification item contains, but nothing critical to correct invocation is missing.

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 single parameter unreadOnly is fully documented in the schema (100% coverage), and the description never mentions it, offering a possible implicit lead with '各组织开关', which does not map to the parameter. With coverage this high the schema does the work and baseline 3 applies. No added meaning or defaults are contributed beyond the schema.

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 the resource and scope: '本人组织通知及各组织开关' (my organization notifications plus each organization's switch), which distinguishes it from the generic sibling list_my_notifications. It also clarifies that items.id is a deliveryId. The phrasing is telegraphic and the '各组织开关' clause is ambiguous, but a reader can tell what is returned.

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?

Names the follow-up tools explicitly (mark_organization_notification_read to mark read, update_my_organization_membership to disable promotion), effectively routing the agent for downstream actions. It also gives a negative usage rule: '较重勿循环或放日报' – do not loop it or put it in a daily digest. There is no positive statement of when to call it, but the guidance goes beyond most siblings.

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