Toggle Layer Labels

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

Annotations already declare readOnlyHint=false, destructiveHint=false, idempotentHint=true, and openWorldHint=false, so the safety profile is covered. The description adds only a generic note that write and path restrictions follow service capabilities, which hints at permission/path constraints without specifics — modest value beyond the annotations.

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?

It is a single short, front-loaded statement with no padding. Brevity is achieved, but partly by under-specification rather than by tight editing.

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?

This is a mutation tool with four undocumented parameters and 0% schema coverage, so the description carries the full burden but delivers almost none of it. The output schema does exist, so return values need not be described, but the input contract is entirely unexplained.

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 there are four required parameters (aprx_path, map_name, layer_name, show_labels), yet the description names none of them. The vague 'path restrictions' phrase barely gestures at aprx_path and leaves map_name, layer_name, and the boolean show_labels unexplained.

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 says 'ArcGIS Pro: toggle layer' (切换图层), which is a recognizable verb+resource, but it omits the defining object — labels — that the tool name and title carry. Against siblings like arcgis_pro_set_layer_visible, arcgis_pro_upsert_label_class, and arcgis_pro_update_label_expression, it gives no basis for telling this apart.

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 statement of when to use this tool versus alternatives, no preconditions, and no exclusions. The agent must infer usage entirely from the tool name and the sibling list.

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