check_napcat_environment

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

With no annotations, the description carries the full behavioral burden. It discloses the inspection scope (environment, ports, accounts, version diff), which implies a read-only diagnostic, but never states whether it requires permissions, how long it takes, or what it returns. Adequate but with clear gaps for an annotation-free tool.

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 selection condition. No filler; every clause earns its place.

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 diagnostic with no output schema, the description enumerates what is inspected (environment, ports, accounts, version comparison), which is enough for an agent to know what the call covers. It does not describe the shape of the result, a minor gap given there is no output schema.

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 per the rubric the baseline is 4. There is no parameter syntax to clarify, and the description correctly implies a no-argument invocation.

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 verb (检查/check) plus concrete resources: local NapCatQQ runtime environment, service port status, saved account list, and comparison against the latest GitHub Release. This is a clear, non-tautological purpose. It does not explicitly name the sibling tools it differs from (e.g., get_napcat_status), so it falls 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?

Provides clear when-to-use guidance: call it when uncertain whether NapCat is deployed, running, or has an update available. This gives real context for selection. It stops short of naming alternatives or when-not-to-use conditions, so it is not a 5.

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