anon_get_open_me

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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so the safety profile is covered. The description adds genuine behavioral context beyond that: the API-key auth requirement and the non-obvious semantics of the returned 'permissions' field (intersection of key scopes and the holder's real-time role permissions).

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?

Three short clauses, front-loaded with the purpose, followed by the auth precondition and the permissions semantics. No filler, and the endpoint string is compact context.

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 output schema, the description carries the burden of describing the return. It explains the permissions field but does not indicate what else the identity payload contains (e.g., key name, owner, role), leaving the response shape only partially characterized for a read tool.

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 of 4 applies. There is nothing further the description could add on parameter semantics.

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 gives a specific verb and resource in Chinese: '查看当前 API 密钥身份' (view the current API key identity), which is a self-distinguishing purpose among mostly resource-scoped get_* siblings. It does not explicitly contrast itself with any alternative tool, so it stops short of a 5.

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 the precondition '需 API 密钥调用' (requires an API key to call), which is real usage context. However, it gives no when-to-use/when-not guidance or routing relative to sibling endpoints like anon_get_accounts or anon_get_project, so usage is only implied.

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