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

Annotations already flag destructiveHint=true and openWorldHint=true, and the description adds real consequence detail beyond them: approval establishes the join, may remove the org from its previous alliance, and re-links 进驻 permissions; rejection notifies the applying organization. It also surfaces the auth requirement (login + alliance manage), which the annotations do not convey.

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 single paragraph with the auth/permission requirement front-loaded, then consequences of each decision, then scope. Every clause carries information and none is redundant with the title.

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, non-idempotent mutation with no output schema, the description covers permissions, required inputs at a high level, and the divergent effects of approve vs reject. The main gap is not explaining the linkId/allianceId parameter formats, which the schema leaves at 0% coverage.

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 load. It does explain decision (批准/拒绝) and reason (原因) and references confirming the 组织, but linkId and its relationship to allianceId are never clarified, leaving two of four parameters effectively 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?

States a specific verb (审核/review) and resource (组织加盟申请/organization alliance join request), and the trailing clause "只处理组织加盟申请" explicitly scopes it away from ambiguous siblings like bulk_review_organization_applications or review_signup_submission. An agent can distinguish this from the adjacent review/respond tools without opening a schema.

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?

Gives concrete prerequisites (【需要登录】and 須联盟 manage) plus a workflow hint (先读工作台申请及完整授权, i.e. read the request from the workbench first). It does not name an explicit alternative tool to use for the other review cases, so it stops short of full when/when-not routing, but the context is clear.

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