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

Goes well beyond the idempotentHint/destructiveHint annotations: it discloses that OMITTED FIELDS ARE LEFT UNCHANGED, that name/description/type/terms/form edits trigger re-consent and that name/type push certification into pending review, and that certain fields are owner-only. Some clauses ('成员可见须确认', '按身份限权') are terse enough to be ambiguous, keeping it from a 5.

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?

Extremely compressed — one sentence of semicolon-separated fragments with abbreviations and no front-loaded statement of what the tool does. Every clause carries information, but the telegraphic style makes it slow to parse and buries the purpose behind constraints.

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 an 11-parameter mutation with nested objects and no output schema, the description covers the crucial operational facts: role requirements, read-before-write, partial-update semantics, side effects on consent/verification, and delegation of logo/alliance concerns. It omits what the call returns or whether changes apply immediately, which is the main remaining gap.

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 100%, so baseline is 3; the description earns a step up by adding cross-parameter semantics the schema cannot express — partial-update behavior ('省略不改'), which fields require owner rights, and which edits cascade into re-approval or pending verification. It does not detail the terms/formFields whole-array replacement that the schema hints at, but that is the schema's job here.

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 makes clear this is a mutating edit of organization profile fields (visibility, join policy, terms, form, location, directory, member posting rights) and explicitly separates out logo changes to set_organization_logo and alliance settings to a separate path (联盟另管). It is dense and does not open with a plain statement of purpose, but an agent can still tell what it does and distinguish it from near neighbors.

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?

Explicit prerequisite (先get_organization), explicit role gate (OWNER/ADMIN), and an explicit routing rule for one field (logo用set_organization_logo) plus '联盟另管' to steer alliance cases elsewhere. It stops short of naming when NOT to use it for the other overlapping siblings (update_my_organization_membership, update_my_profile), so not a 5.

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