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

Annotations already declare destructive=true/readOnly=false, and the description goes well beyond them: it explains index reflow, variant-key rebuilding, why stale keys matter, the cascade of owned assets (background, overlay, padding, slot content), the sharing exception when another section renders the layout, and that dropped content is reported.

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 action is front-loaded in the first short sentence, and the following sentences each add distinct destructive-behavior detail. The enumeration of owned assets is slightly padded but each clause carries real meaning.

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 destructive, no-output-schema tool, the description covers what is destroyed, what is preserved via sharing, the one hard prohibition, and that dropped content is reported. Only the exact returned payload and any authorization requirements are left unstated.

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 only 33% — only 'index' is documented as 1-based, while projectId and pageName have no descriptions. The description never mentions any parameter or clarifies how the index relates to the resulting reflow, so it does not compensate for the coverage gap.

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 opens with a concrete verb+resource: 'Take a section off a page.' The resource noun ('section') separates it from nearby siblings like remove_page and remove_post, but it never explicitly contrasts itself with replace_section or duplicate_section, so differentiation is left to inference.

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 when-not rule ('the last Post Featured Area or Post Content ... cannot be removed'), which prevents a class of invalid calls. It does not point to alternative tools (e.g. replace_section) when removal is the wrong operation, but the context is otherwise clear.

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