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

Annotations only carry destructiveHint=false, so the description does the heavy lifting: it discloses the permission requirement, the ownership side effect (caller becomes 负责人), automatic employee enrollment, blanket authorization, and — most valuably — that creation and alliance-joining are two separate non-atomic steps, plus a safe recovery path. It does not say what happens to a half-created org if step two fails.

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-loaded with the permission gate, then the created-side-effects, then the failure-recovery rule — a sensible priority order with little filler. Sentences are dense but each carries a distinct operational instruction.

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?

Auth requirements, side effects, and the non-atomic two-step workflow are well covered, which is the hardest part of this tool. However, with 10 parameters at 0% description coverage, a nested terms object, and no output schema, the definition leaves the agent unable to construct a correct call without outside knowledge.

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 0% across 10 parameters including a nested terms object, and the description only gestures at '组织字段/协议' without mapping to any parameter. Nothing explains joinPolicy, visibility, investorEnabled, or the non-obvious spaceModules minItems=2 constraint, so the agent must infer everything from enums and defaults.

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 (create an alliance-owned organization) and adds scope detail — the creator becomes the owner and the org is created under an alliance. It is distinguishable from siblings like create_organization and attach_alliance_organization through the '联盟自有组织' framing and the two-step flow note, though it never names those siblings explicitly.

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 a clear precondition (login + alliance manage permission) and an explicit failure path: on error, check list_my_organization_memberships for an already-created org and decide whether to attach rather than retrying. Missing an explicit statement of when to prefer create_organization over this tool for standalone orgs.

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