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

With no annotations, the description carries the full burden and does disclose two things the rubric credits: the auth requirement (login + alliance manage permission) and the blast radius (cancels only pending invitations; already-joined organizations are untouched). It omits reversibility (must the invitation be re-issued?), behavior on an already-accepted invite, and failure modes.

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?

A single dense sentence with the gating constraint (login) front-loaded and zero filler; every clause carries information. Slightly compressed to the point that the verification instruction reads as a run-on.

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 2-parameter mutation with no annotations and no output schema, the description covers purpose, permissions, and effect scope, which is a reasonable minimum. It leaves an agent guessing about the return value and about what happens if the invitation is no longer pending.

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% and both parameters are undocumented (linkId is a bare $ref to the allianceId string). The description only alludes to their meaning via '核实 linkId 与组织', which hints that linkId identifies the invitation and allianceId the organization, but supplies no format, source, or lookup guidance to compensate for the empty 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 a specific verb+resource (撤回联盟发出的加盟邀请 / cancel an alliance's outgoing join invitation) and adds a scope boundary that separates it from removal-type siblings: '只取消待接受邀请，不移出已加盟组织'. It never names the nearest alternatives (cancel_my_alliance_application, revoke_organization_member_invite, cancel_organization_alliance_request) explicitly, so an agent still has to reason about which cancel it wants.

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?

'【需要登录】須联盟 manage' plus '工作台核实 linkId 与组织后确认撤回' implies the context (an alliance manager working from the workbench) and a verify-then-confirm precondition. However there is no explicit when-to-use versus sibling cancellation/revocation tools and no statement of when NOT to call it (e.g. after the invite was accepted).

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