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

With destructiveHint=true already declared, the description adds substantive behavior: it closes 联盟共享 and 进驻访问, notifies the organization manager, requires login plus manage permission, and reassures that 组织仍存在 (the org persists). This goes beyond the annotations to explain the real side effects of the destructive call.

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?

It front-loads the login and permission requirement, which is the most important gating info. But the body is a dense run-on of semicolon-linked clauses that mixes preconditions, side effects, and platform-ops caveats, making it harder to parse than a cleanly structured description.

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 destructive, permission-gated mutation with no output schema, the description covers preconditions, side effects, post-state reassurance, and who may perform it. Only the parameter-level detail and explicit sibling routing are missing, which are minor against the annotations.

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 the burden. It references 组织/联盟 (allianceId, organizationId) and 原因 (reason), touching all three parameters conceptually, but adds no format, length, or value guidance for any of them, so it only partially compensates.

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 gives a specific verb and resource: detaching/releasing 自有 or 移出 a 加盟 organization from an alliance, matching the name detach_alliance_organization and distinguishing it from the attach sibling. The two modes (release own vs. remove a joined member) are stated but not sharply delineated, which slightly clouds the exact 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 states prerequisites (【需要登录】須联盟 manage) and a hard constraint (官方分录只允许平台运营处理), which is useful context. However it never names an alternative tool or explains when to prefer this over leave_organization_alliance or attach_alliance_organization, leaving routing to inference.

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