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

Annotations already declare readOnly=false, idempotent=true, destructive=false, but the description adds the auth requirement (login + OWNER/ADMIN), the server-side re-checks (admin permission, member status, cloud-user limits), and the scope limitation that member-level settings are untouched. This is meaningful behavioral context beyond the structured hints.

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?

Front-loads the permission bracket and purpose, then prerequisites, then scope boundary. Dense but each clause carries information; no filler sentences, though the packed single block is slightly harder to scan than cleanly separated sentences.

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 non-destructive idempotent mutation with annotations present and no output schema, the description covers auth, prerequisites, scope, and server-side validation, which is enough to call it correctly. Nothing critical is missing, though it does not describe the success/failure response shape (which the absent output schema would otherwise require).

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 coverage is 67%: membershipId is well documented in the schema and reinforced here, organizationId is briefly documented, but canPublishActivities has no schema description. The description compensates by framing it as the on/off switch for publishing rights, adding meaning the bare boolean lacks.

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 pair (开启或关闭 = enable/disable) on a specific resource (a member's activity-publishing permission), and the title confirms it. It is clearly distinguishable from siblings like set_organization_member_role or remove_organization_member without opening any 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 the prerequisite workflow explicitly (obtain membershipId from list_organization_members, confirm member and switch, then call) and draws a clear 'when-not' boundary (this only changes admin authorization, not the member's own share/hide settings). It stops short of naming the alternative tools the agent might confuse it with, so it is clear context rather than full when/alternatives routing.

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