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

Annotations already declare read-only, idempotent, non-destructive, closed-world behavior, so the safety profile is fully covered without the description. The description adds some value by disclosing that the payload is a fixed 61-item set tied to a specific standard version plus side-loaded quick-reference and explainer content. However, much of the return-shape detail overlaps with the existing output schema, so the net addition is modest.

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 short sentences, front-loaded with the standard ID and purpose, followed by the returned content. The bolded 清单本体 highlights the primary payload and every clause carries information; nothing is filler.

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 no-parameter, read-only list tool with an output schema already present, the definition covers purpose, fixed content, and extra fields (quick reference, explainer) adequately. The only shortfall is that it never states how this relates to the sibling retrieval tools, leaving selection logic to the agent.

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, which is the baseline-4 case: there is nothing for the description to disambiguate. The description correctly implies a parameterless, fixed-content call rather than suggesting any filtering or query input.

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 names a specific verb and resource: it retrieves the GB/T 47746-2026 self-check checklist for enterprises auditing their own AI customer service. The scope is pinned to a concrete standard and the content (61 items with defined fields) is spelled out, so the tool is distinguishable in substance. It does not explicitly contrast itself with siblings like standard_info, which keeps it from 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?

Usage context is implied clearly enough — 'enterprises check whether their AI customer service meets the standard' — so an agent can infer when to call it. There is no explicit when-not guidance and no named alternative, so the agent must reason about choosing this over standard_info or the search/get tools.

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