Drawing: Apply ISO Layer Set (bootstrap)

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

Not only is destructiveHint=false but description adds 'idempotent — existing layers are not modified', which is a key behavioral trait beyond annotation.

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 fluff; front-loaded with core purpose and key property (idempotent).

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?

Simple tool with one param and output schema; description covers purpose and idempotency. Could mention exactly what layers are created or that it only creates missing layers.

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 coverage is 100% and description adds no additional meaning to the 'standard' parameter beyond what's already in the schema.

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?

Description clearly states it bootstraps a full ISO-conformant layer set with correct colors and lineweights, and distinguishes from siblings like layer_create or template_apply_layers by focusing on a complete standard set.

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?

Implies usage for initial setup via 'bootstrap', but no explicit when-to-use or alternatives mentioned. Does not differentiate from template_apply_layers or other layer tools.

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