Build Las Pyramid

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

Annotations already declare that this is a non-read-only, idempotent, non-destructive operation. The description adds useful context by saying it builds or updates a display pyramid and can use constrained class-code weights, but it does not disclose side effects, permissions, or where the pyramid is stored.

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?

The description is a single front-loaded sentence with no filler, and the core purpose comes first. It is appropriately terse, though adding no structural breakdown for a four-parameter mutation tool keeps it from being maximally helpful.

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 safety. However, with zero schema descriptions, two required parameters, and no usage guidance, the description is incomplete for a LAS pyramid build/update operation; it omits what 'expected_las_dataset' means and how point selection affects the result.

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% across four parameters, so the description must compensate. It mentions '.lasd' and 'class-code weights' for two parameters, but leaves 'expected_las_dataset' and 'point_selection_method' (default Z_MIN) entirely unexplained, which is a significant 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 states a specific operation ('构建或更新显示金字塔') on a specific resource ('.lasd'), which lets an agent identify it as a LAS dataset pyramid tool rather than a raster pyramid or LAS statistics tool. It does not explicitly name or contrast sibling alternatives, but the verb+resource combination is clear enough.

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?

The description gives no explicit when-to-use or when-not-to-use guidance, nor does it name alternatives such as arcgis_pro_raster_build_pyramids, arcgis_pro_las_dataset_info, or arcgis_pro_calculate_las_statistics. The phrase '精确确认的 .lasd' hints at a pre-condition but is not explained.

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