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

Annotations already state that this is a non-read-only, non-destructive, non-idempotent, closed-world operation. The description adds useful behavioral detail by explaining that the template repository is copied, a new owned project is created, and no prompt build starts.

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 definition is brief and front-loaded: it states the core operation first, then clarifies the remix behavior and the required parameter source. Every sentence contributes useful information.

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?

With one fully described parameter, annotations covering safety and mutability, and an output schema present, the description supplies the remaining context an agent needs. The no-prompt-build caveat is especially helpful for selecting and interpreting this tool.

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 template_id parameter is fully documented in the schema as a UUID from templates_list. The description repeats the source of the ID but adds no further syntax or format detail beyond the structured 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?

The description gives a specific verb and resource: copy a public template into a new project for the authenticated user. It also distinguishes this operation from template listing by naming templates_list as the source of the required ID.

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 clearly positions this as the app-remix flow and says to obtain the template_id from templates_list. It does not explicitly exclude other project-creation or build-starting alternatives, but the intended context is clear.

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