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

The annotations already declare readOnly=true, idempotent=true, closed-world and non-destructive, so the safety profile is covered. The description adds real value beyond that: it explains the link's payload differs by design type — catalog wallpaper encodes product, colour, composition, room and studio settings, whereas an own-image design yields a personal copy for the customer.

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?

Three short sentences, front-loaded with the action and then the branch-specific payload detail. Nothing is padded, though the catalog-versus-own-image detail is somewhat dense and would read better if split or bulleted.

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 one-parameter read tool without an output schema, the description does explain the differing link content per design type, which is the key behavioral nuance. It still omits how design_id is sourced and how this tool relates to the near-identical checkout-link sibling, which an agent needs to pick correctly.

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?

There is a single required parameter with 0% schema description coverage, so the description carries the full burden of explaining design_id. It only refers to 'dit ontwerp' (this design) without saying what ID is expected, how to obtain it, or whether it comes from start_wallpaper_design or get_wallpaper_design.

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 concrete outcome: it produces the link that opens this design in the createdby.you studio, where the customer checks out. The resource and result are clear, but it never distinguishes itself from the very similar sibling get_wallpaper_checkout_link, leaving an agent to guess which of the two to call.

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?

Usage is implied by the handoff narrative (the customer puts the design in the cart and pays), so the intent context is understandable. However, there is no explicit when-to-use versus get_wallpaper_checkout_link or get_wallpaper_quote, and no stated preconditions for the design being ready to hand off.

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