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

Annotations only declare readOnlyHint=true, and the description adds real operational context: login requirement, a permission gate, cursor-based pagination ('按分分页'), inclusion of cloud users, and a scope restriction. The mention of 'conversationId' is odd since no such parameter exists, which slightly erodes trust, but overall it adds substantial behavior beyond 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?

It is short and front-loaded with the login/auth requirement, with no filler. But the fragmentary bracket-notation style and the stray conversationId reference make it cryptic rather than clean, and clarity is sacrificed for brevity.

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 read-only list tool with no output schema, the description covers auth, pagination, scope and chaining, which is fairly complete. But the phantom conversationId parameter and unexplained userId/cursor leave gaps an agent would need to resolve by trial.

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 only 33% (just organizationId is documented), so the description must compensate for cursor and userId — but it does not. '按分分页' vaguely implies cursor paging without explaining it, and userId is entirely unaddressed, leaving two of three parameters effectively undocumented.

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 conveys a list operation over organization match pairs and the '【组合链】列表id→get_organization_match_pair' clause distinguishes it from the detail tool get_organization_match_pair. It is terse and fragmentary, but an agent can tell what resource is listed and route to the right sibling, though it doesn't explicitly separate it from list_my_organization_matches.

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 states prerequisites ('需要登录' login required, '需撮合管理能力' matchmaking management permission) and a chaining hint to get_organization_match_pair, which is useful context. However, it never states when to prefer this over list_my_organization_matches or other match-listing siblings, so the alternative selection is only implied.

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