Dataset Schema

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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint=false, and destructiveHint=false, so the safety profile is fully covered. The description adds that this is a single consolidated snapshot rather than piecemeal queries, which is useful, but says nothing about output size, performance, or failure modes.

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 front-loaded sentence that enumerates the returned components with no filler. It is appropriately sized, though a second sentence on the path argument or alternatives would have earned 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?

An output schema exists, so return values need not be explained, and annotations cover the read-only profile. The remaining gap is the completely undocumented dataset_path argument and the absence of routing guidance among the many overlapping schema/list siblings.

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?

Schema description coverage is 0% and the description never mentions dataset_path, so neither source explains what path format is expected (feature class, dataset, layer file, etc.). With one undocumented required parameter, the description fails to compensate for the schema gap.

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 clear verb (读取) and resource (数据集方案快照) and enumerates exactly what is returned: fields, indexes, spatial reference, subtypes, attachments, and relationship classes. This distinguishes it in substance from narrow siblings like list_fields or attachments_info, though it never names those alternatives explicitly.

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?

There is no when-to-use guidance and no mention of alternatives, despite many overlapping siblings (arcgis_pro_describe, arcgis_pro_list_fields, arcgis_pro_list_subtypes, arcgis_pro_relationship_classes, arcgis_pro_attachments_info). The agent must infer that this is the all-in-one option from the word 一体化 alone.

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