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

Annotations only supply readOnlyHint=true; the description adds real behavioral context beyond that: the auth/permission gate, cursor-based pagination, and a data-minimization boundary listing what is deliberately NOT read (审计metadata、协议签名、联系方式、私聊内容). The interpretation caveat about non-delivery/non-payment is unusually valuable for downstream reasoning. It omits result ordering and rate/volume behavior, so not 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?

Dense and front-loaded with information rather than fluff; each clause (auth, pagination, filter, field scope, caveat) earns its place. The ordering is suboptimal — permissions precede any statement of what the tool returns — and the nextCursor/cursor naming inconsistency costs a point.

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 read-only list tool with four parameters and no output schema, the description does the heavy lifting: it defines the returned fields, the exclusions, pagination, and permission requirements, so an agent knows what it will get and when it is unauthorized. Remaining gaps are result ordering and the unmentioned limit parameter, which are minor for this tool class.

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. It covers action filtering and cursor pagination, and implies organizationId via 本组织, but leaves limit completely unmentioned and gives no format hints for action (the schema's uppercase pattern) or for cursor. It also names the cursor 'nextCursor' while the schema property is 'cursor', a minor mismatch the agent must reconcile.

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 never opens with an explicit verb+resource sentence, but it effectively defines the resource by enumerating exactly what is returned: 操作类型、对象id、操作人和时间 for the current organization. Combined with the name and title, an agent can confidently tell this is a read of the organization's operation log. The lack of a front-loaded purpose statement and of any explicit sibling differentiation keeps it below 5.

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 states the precondition clearly: 登录 plus 本组织当前管理权限, which tells the agent this cannot be called on arbitrary organizations. It also warns that a record does not prove 通知送达、付款或业务已履约, which is genuine usage guidance about how to interpret results. No alternative sibling tool is named for related needs (e.g. notification or analytics listings), so it falls short of a 5.

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