Apply Layer Template

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

The annotation indicates it's not read-only, and the description confirms it creates layers with standard colors and lineweights. This discloses the mutating behavior. However, it doesn't specify what happens if layers already exist (overwrite or merge), which could be useful.

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?

Two sentences with no wasted words: first states the action, second lists templates and what the tool creates. Front-loaded and efficient.

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 one-parameter tool with an output schema, the description covers the essential aspects. It could briefly mention whether existing layers are overridden, but given the simplicity, it's mostly complete.

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 'template' is described in the schema and reinforced in the description with a list of valid options. Since schema coverage is 100% and the description adds no new ambiguity, this is fully clear.

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 it applies a standard layer set from a predefined template, listing available templates (architectural, mechanical, electrical, piping). This distinguishes it from sibling tools like layer_create (individual layers) and template_list (listing templates).

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?

It describes when to use (to apply a template layer set) and lists templates upfront. It doesn't explicitly exclude alternatives, but the context makes it obvious that this is for bulk layer creation rather than manual layer management.

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