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

Beyond the annotations (destructive/non-idempotent already declared), it discloses a real behavioral trait: every id is re-issued, including repeater item _ids, because Elementor keys CSS per-element id, so duplicated ids would leak styling. It also describes the return payload (id_maps) and notes the dry_run preview, giving the agent operational context the annotations do not.

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?

Front-loaded with the verb+resource, then the workflow, then the id rationale, then the return value — a sensible ordering. It is verbose in the middle ('each is another chance to typo a hex or miss a radius') and the marketing cadence costs a little, but each sentence carries 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?

For a 6-parameter destructive tool with no output schema, this covers everything an agent needs: what it does, when to use it, the id-collision behavior, and the return shape (id_maps). Nothing material is missing.

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%, so the baseline is 3; the description adds meaning on top by explaining that node_id is usually the card CONTAINER rather than a widget inside it, and by showing how id_maps let you patch a specific copy's insides via overrides without re-reading the page.

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?

States a specific verb+resource with scope: 'Duplicate an element and its whole subtree N times as siblings.' It distinguishes itself from the many page-level siblings (wp_copy_page, wp_clone_page, wp_replace_section) by making clear it operates on a single element/subtree, not a whole page.

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?

Explicitly frames when to use it ('THE way to build a row of cards, a pricing grid...') and the recommended workflow (build one, screenshot, replicate, swap only content). It also articulates the alternative it replaces (hand-authoring six cards) and why that fails, which is the strongest form of usage guidance.

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