Set Layer Order

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

The idempotentHint annotation indicates the tool can be safely called multiple times. The description does not add further behavioral context (e.g., whether the order is persisted, if it triggers a redraw). With annotations providing basic safety, a score of 3 is appropriate.

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 two concise sentences with no extraneous words. The key information is front-loaded.

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 simple tool with one parameter and no output schema, the description covers the parameter semantics and overall function. It lacks details on error handling or prerequisites, but the tool is straightforward.

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 schema lacks descriptions for the parameter, but the tool description explains that 'layer_ids' is an ordered list from top to bottom, adding meaning beyond the schema type definition.

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 clearly states the action ('set') and the resource ('explicit layer draw order'), and specifies the order direction ('from top (drawn last) to bottom'). This is specific and distinguishes it from sibling tools that modify layer properties or visibility.

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?

No guidelines are provided about when to use this tool versus alternatives like 'move_layer_to_group' or 'set_layer_visibility'. There is no mention of prerequisites or when not to use it.

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