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

With readOnlyHint already set, the description adds useful behavioral context: login is required, the caller must be an organization member, and invitations/applications/internal relationships are trimmed according to server-side management capabilities. It does not explain output format or pagination, but it meaningfully extends the annotation.

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?

The definition is compact and front-loads the login requirement, then moves to member scope and manager usage. The sentence is dense with semicolons but contains no clear waste.

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 one-parameter read tool with annotations and no output schema, the description covers access requirements and key decision fields, but it is incomplete against the title's promise of '待办' (to-dos) and does not fully explain return contents or data scope.

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?

There is one required organizationId parameter and schema description coverage is 0%. The description does not explain what the organizationId represents, whether it must be the caller's organization, or how it is used to scope the alliance status, so it does not compensate for the schema gap.

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 the concrete data the tool exposes: current alliance state, requiredGrants, share, and capabilities, framed around manager decisions. It is specific enough to infer a read-only status/relationship retrieval, though it does not explicitly distinguish itself from sibling tools such as get_alliance or get_my_alliance_application_state.

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?

It clearly states when to call it: before a manager joins, changes authorization, leaves the alliance, or negotiates revenue share. It also adds a negative guideline not to infer based on organization type. It stops short of naming alternative tools for comparison.

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