装柜计算器

container-load

Read-onlyIdempotent

装柜计算器（Container loading calculator）：每柜装多少箱、要几个柜、怎么摆。 Cartons per container, containers needed, and how to stack them. 读取数据 / Reads: containers@current. 输入为精确的十进制字符串 / Inputs are exact decimal strings. 每箱毛重 grossWeight 可以不填：用户没给重量就不要填，绝不要编一个。不填时只按尺寸算能装多少箱、要几个柜，没有核对载重上限；回答里第一条 warning 的 message 说明了这一点，回复用户时必须把这句话原样带上。 / grossWeight may be left out: when the user gave no weight, do not fill it and never invent one. The answer is then a count by size alone with the payload limit not checked; the first warning’s message says so, and your reply must pass that sentence on. 用户没有给的数字和日期不要自己编：必填的先问用户，选填的不填。 / Never make up a figure or a date the user did not give: ask for a required one, leave an optional one out. 回复时引用回答里的 provenance.source_line / Quote provenance.source_line in your reply.

A4.6/5.0

Behavior5/5

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

Beyond the readOnly/idempotent annotations, it discloses non-obvious behavior: omitting grossWeight drops payload-limit checking entirely, the first warning message states this and must be relayed verbatim to the user, and the reply must quote provenance.source_line. These are real operational consequences an agent could not infer from the schema or annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The purpose is front-loaded and each rule is actionable, but the bilingual duplication roughly doubles the length, and the 'never invent a figure' instruction is stated twice (once for grossWeight, once generally). Content earns its place, though a bit of redundancy could be trimmed.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With 11 parameters, an output schema, and rich annotations, the description covers what remains: the data source, the optional-weight branch and its warning contract, input-format refusal behavior, and which output fields (normalized, provenance.source_line) matter in the reply. Nothing needed to call it correctly is missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is already 100%, so the baseline is 3. The description adds meaning the schema does not: grossWeight is genuinely optional and its absence silently changes the calculation semantics (size-only count, no weight check), plus the exact-decimal-string input rule with refusal-and-normalize behavior.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description names a specific computation and its three outputs: cartons per container, number of containers, and stacking arrangement. An agent can immediately distinguish this from siblings like cbm (volume) or unit-convert, since the tool answers a loading-plan question rather than a measurement conversion.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It gives operational when/when-not guidance: grossWeight may be omitted when the user gave no weight, required figures must be asked for, optional ones left out, and reads come from containers@current. It does not name a sibling alternative or a scenario where a different tool should be preferred, so it falls short of full routing guidance.

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