Set Current Layer

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

The description explains that it sets the current layer, which is a mutation operation. Annotations already indicate readOnlyHint=false and destructiveHint=false, so the description adds no further behavioral nuance beyond what annotations provide.

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 extremely concise—one sentence of 8 words—with the verb 'Set' front-loaded. Every word is necessary and contributes to understanding the tool's function without redundancy.

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?

Given the tool's simplicity (one required parameter, no nested objects, output schema exists), the description is complete. It clearly states the tool's purpose and effect, and no additional information is needed for an AI agent to use it correctly.

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 single parameter 'name' is fully described in the input schema with 'Layer name to set as current'. The tool description does not add any additional meaning or context beyond the schema, so it meets the baseline expectation.

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 verb 'Set' and the resource 'active/current layer' with context 'for new entities'. Among sibling layer tools, this distinguishes itself by specifying which layer becomes the current layer for new entity creation.

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 does not explicitly state when to use this tool versus alternatives, nor does it mention prerequisites or exclusions. However, the purpose is straightforward, and the context of setting a current layer is implicitly understood as a prerequisite for creating new entities.

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