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

Beyond the annotations, it discloses that the item is created as a draft, that a person must approve it in Royally before anything changes on the site, and that the connection cannot undo or reverse the change. It also describes the return values, which is valuable behavioral context.

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 concise, front-loads the purpose and usage condition, and then adds only high-value details about return values, approval flow, and irreversibility. Each sentence contributes useful information without repetition.

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 no output schema, the description still explains what is returned: the new post ID and edit URL. It also covers the approval workflow, the fact that nothing changes on the site until approval, and the lack of undo, which are the key behavioral facts an agent needs before calling it.

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 description coverage is 100%, so the parameters are already well documented in the schema. The description does not add parameter-specific meaning beyond confirming that the tool creates either a post or a page; baseline 3 is appropriate because the schema carries this dimension.

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 states a specific verb and resource: it creates a draft post or page pre-marked for Elementor with a blank canvas. It also distinguishes this from generic post creation by describing the result as a layout shell for Elementor design, which is enough for an agent to tell it apart from sibling create-page and create-post tools.

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 gives a clear usage condition: use when the user wants a new layout shell to design in Elementor. It does not explicitly name when to avoid it or point to alternatives such as elementor-build-composition, elementor-manage-elements, or generic post/page creation tools.

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