check_napcat_environment

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

No annotations are provided, so the description carries the full behavioral burden. It succeeds in disclosing what is inspected (environment, ports, accounts, remote version), which implies a non-destructive read, but it never explicitly states that it is read-only, that it makes a network call to GitHub, or how quickly it returns. Adequate but not rich.

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?

Two sentences, front-loaded with the concrete checks and followed by the trigger condition. No filler, no repetition of the name, and each clause adds actionable information.

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 parameterless, annotation-free, output-schema-free tool, the description covers what is inspected and when to use it, which is most of the agent's decision path. It would be stronger if it hinted at the shape of the returned diagnostic (e.g., deployment/version verdicts) or that it may take longer due to the GitHub request.

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 and the schema description coverage is 100%, so there is nothing for the description to clarify on input semantics. The baseline for a parameterless tool applies.

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 ('检查' / check) plus a clearly enumerated resource set: local NapCatQQ runtime environment, service port status, saved account list, and a version comparison against the GitHub latest Release. The only gap is that it never distinguishes itself from close siblings like get_napcat_status or list_qq_accounts, which appear to overlap on the same subject matter.

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 an explicit trigger condition ('当不确定 NapCat 是否已部署、是否正在运行或是否有新版本可更新时'), giving the agent clear context for when to reach for it. However, it neither names alternatives nor gives a when-not-to-use boundary, so it stops short of full routing guidance among siblings such as get_napcat_status or deploy_or_update_napcat.

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