duplicate_pre_built_design

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

Annotations are absent, so the description must fully disclose behavioral traits. It only labels the action as 'Mutating', indicating state change, but omits details like permissions needed, side effects (e.g., the original pre-built design remains unchanged), or any potential impact.

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?

Extremely concise, using only 7 words. Every element ('Mutating:', 'copy', 'SendGrid pre-built design', 'into your account') serves a clear purpose 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?

For a simple 2-parameter tool with no output schema, the description covers the basic action. However, it lacks usage context and behavioral notes that would aid an AI agent, such as prerequisites or what the copied design entails.

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%, providing descriptions for both parameters. The tool description adds no additional semantic meaning beyond what the schema already offers, so it meets the baseline.

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 copies a SendGrid pre-built design into the user's account, with a specific verb 'copy' and resource 'pre-built design'. It distinguishes from siblings like 'duplicate_design' by focusing on pre-built designs rather than existing account designs.

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 explicit guidance on when to use this tool versus alternatives such as 'create_design' or 'duplicate_design'. The description does not mention the typical workflow or provide exclusion criteria.

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