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

With no annotations, the description carries the full burden and does well: it discloses auth requirements, side effects (old alliance relationship removed, linked access cascade, notification to the old alliance) and an implicit side effect (employees auto-join). It does not say whether the merge is reversible or how conflicting memberships are handled, and the '全部7项授权' (all 7 grants) reference is unexplained without consulting sibling grant tools.

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 is a dense but efficient two-sentence block, front-loaded with the login/permission gate, then side effects, then the pre-check step. The single cryptic aside about '7 grants' slightly dilutes the otherwise tight structure.

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 two-parameter mutation with no annotations and no output schema, the description covers prerequisites, side effects, verification steps and failure handling, which is nearly everything an agent needs before calling it. Missing only success/reversibility information and the meaning of the referenced grants.

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 compensate. It only loosely maps the two parameters to 'target alliance' and 'organization' ('确认目标联盟、组织'), without specifying ID formats or what '确认' means concretely — you are told to verify them but not what a valid value looks like.

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 names a specific action ('并入自有' – attach the organization as alliance-owned) and resource (alliance + organization), and it embeds a distinction between becoming alliance-owned versus an existing share/affiliation ('若换联盟会移除旧关系'). However, it never names a sibling (e.g. create_alliance_organization, apply_organization_to_alliance, set_alliance_organization_share) to differentiate itself, so the distinction must be inferred from the title.

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?

Preconditions are explicit ('需要登录', alliance manage role, org owner) and a required pre-check workflow is given ('先查双方详情'), plus fallback guidance on failure ('失败查实际关系'). It does not state when to use an alternative tool instead, so it stops just short of full routing guidance.

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