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

Annotations already declare read-only, idempotent, non-destructive behavior, so the bar is lower; the description still adds valuable context by requiring login and explicitly stating what is NOT returned (application answers, contact details, platform approval records). It does not describe pagination or response shape, 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?

A single dense sentence with the login requirement front-loaded in brackets, followed by scope and exclusion clauses. Every clause earns its place, though the packing of four distinct facts into one sentence slightly reduces scannability.

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 no-parameter, read-only tool with no output schema, the description covers the preconditions, the categories of data returned, and the categories deliberately withheld — everything an agent needs to decide whether to call it and how to interpret the result.

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?

The tool takes zero parameters, which is the baseline-4 case; there is nothing for the description to disambiguate, and the description correctly spends no words on parameter syntax.

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 (读/read) and resource (本人联盟申请状态) with explicit scope: latest state, mergeable own organizations, and server-side block reasons. It is clearly distinguishable from siblings like submit_alliance_application, cancel_my_alliance_application, and get_organization_alliance_status.

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 usage window (申请成立联盟前, i.e. before submitting an alliance application) and an eligibility precondition (at least two qualified organizations where the caller is the responsible person). It does not explicitly name sibling alternatives such as get_organization_alliance_status, so it stops short of a 5.

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