pan_account

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

With no annotations, the description must carry behavioral disclosure. It does indicate the tool reports account information and login state and names the output categories, which implies a read-only inspection. However, it does not disclose what happens when the user is not logged in, whether any session is created or refreshed, or what error/edge behavior to expect.

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 description is one compact line with the main purpose front-loaded and the specific fields in parentheses. It is economical and readable, though it is a telegraphic noun phrase rather than a full imperative sentence, and 自检 is slightly jargon-like.

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 zero-parameter, low-complexity tool with no output schema, the description covers the core purpose and basic return categories. It is not fully complete because it lacks authentication-edge behavior and does not clarify whether the space list is identical to the output of pan_list_spaces, and no usage alternatives are given.

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 has zero parameters and the schema coverage is 100%, so the schema fully describes the call signature. Per the baseline for zero-parameter tools, no parameter documentation is needed from the description.

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 identifies the resource (交大云盘账户/cloud-drive account) and the action (登录态自检/login-state self-check), and enumerates returned fields: user ID, organization, and space list. It is distinguishable from siblings like pan_login and pan_list_spaces because it is account-centric, though the term 自检 is slightly ambiguous and could be read as a health check rather than a data retrieval.

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?

No guidance is given about when to use pan_account versus its siblings. The description does not mention that pan_login is for establishing a session, that pan_list_spaces is for space listing alone, or any conditions that should route an agent to one tool over another.

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