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

With no annotations, the description carries the full behavioral burden. '取' implies a non-destructive read and it discloses the content type (a checklist), but it says nothing about format, size, or any prerequisites. For a zero-parameter read tool the risk is low, so this is adequate rather than 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?

A single tight sentence, front-loaded with the action and the standard identifier, followed by the use case. Every clause earns its place with no redundancy.

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?

The tool is simple (no params, output schema present), so the description need not explain return values. It covers what is fetched and why, leaving only minor gaps around how the checklist relates to the sibling tools.

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 of 4 applies. The description correctly avoids inventing inputs and simply names the fixed standard being retrieved.

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 pairs a specific verb (取/get) with a specific resource (GB/T 47746-2026 自查清单), so an agent immediately knows this returns a self-assessment checklist for that standard. It does not explicitly contrast itself with siblings like standard_info, but the checklist deliverable is distinctive enough to differentiate.

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 intended scenario — enterprises checking whether their own AI customer service meets the standard — which implies when to reach for it. However, it never says when to prefer this over standard_info or how it differs from the other question/answer tools, so routing guidance is only implied.

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