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

readOnlyHint=true already declares this a safe read, and the description usefully adds that authentication is required and that both list data and counts are returned. It does not mention pagination limits, ordering, or whether blocking/privacy rules filter results, which would matter for a network listing.

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 compact sentence with the auth precondition front-loaded and the payload described immediately after. The '登录;' fragment is slightly terse but wastes no words.

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?

With zero parameters, no output schema and a simple read-only shape, the description covers what is needed: auth requirement, the three returned collections, and counts. Missing only minor operational detail such as result ordering or result-set limits.

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, so the baseline is 4; there is nothing for the description to disambiguate beyond the fact that the whole result set is derived from the authenticated caller.

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 concrete resource (the current user's network) and enumerates the three relation types returned — 关注 (following), 粉丝 (followers), 好友 (mutual follow) — plus counts, so an agent knows exactly what comes back. It stops short of naming how it differs from nearby siblings such as list_network_contacts or search_people.

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?

The leading '登录' and the 'my' scope imply this is for viewing one's own connections, so usage is inferable. There is no explicit when-to-use/when-not guidance and no pointer to alternatives like list_network_contacts, list_connection_requests or search_people.

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