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

No annotations are provided, so the description carries the burden. It does disclose a real behavioral constraint — an API key is required — which is useful auth context. However it never says whether this is a read-only operation, whether it hits rate limits, or what happens without a key, so the safety profile remains unstated.

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 line with the scope front-loaded before the parenthetical details. The key requirement is stated twice ('需 key' and '需 API Key'), which is redundant, but the overall footprint is appropriately small.

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 no parameters and no output schema, the description usefully enumerates the returned fields (homepage, contact info, verification status), compensating for the absent schema. What remains missing is usage context relative to its many siblings, but for a self-lookup tool the definition is close to sufficient.

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 there is nothing for the description to disambiguate; the baseline for a parameterless tool is 4. The description correctly adds no parameter detail because none exists.

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 resource and scope: the caller's own identity overview, enumerating the data it covers (directory homepage, contact info, verification status). The word '本人/当前身份' distinguishes it from the general member-directory sibling, though it never names soloteam_member or soloteam_directory explicitly, so sibling routing is only implied.

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 only guidance is the prerequisite '(需 API Key)'. There is no statement of when to call this versus soloteam_member, soloteam_directory, or soloteam_meta, and no exclusions. The agent must infer that 'me' means the authenticated caller's own profile.

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