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

Annotations cover the safety profile (destructiveHint=false, idempotentHint=true), and the description adds genuine context beyond them: nothing is charged by opening it, and the customer completes edits, additional print areas, group size collection, and checkout on the destination site. It never says what the tool actually returns (a URL string) or whether the link expires.

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?

Four sentences, front-loaded with the tool's effect and followed by what happens downstream and the no-charge caveat. The middle sentence is a long list of destination capabilities, which is informative but slightly overstuffed; overall little waste.

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?

No output schema exists, and the description compensates by explaining that the result is a link that opens the designer, so the agent knows what it gets back. The unaddressed 'visitor' parameter and the absence of any lifetime/idempotency detail about the generated link are the remaining gaps.

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 50%: the nested item, color, sizes, and design_id fields are well documented in the schema, but neither the description nor the schema explains the top-level 'lines' and 'visitor' parameters. The phrase 'when sizes are given, the order lines filled in' loosely maps to the lines structure and the defaults are covered by the schema, so baseline 3 is right.

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 concrete outcome: a link that opens the aipromodesign.com designer with the design pre-loaded on the item/color, and order lines filled when sizes are supplied. That is specific enough to separate it from design_item, quote_order, and revise_design, though it never names those siblings to draw the contrast explicitly.

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?

Gives an explicit trigger — 'use it when the customer is ready to order or wants to keep working' — and clarifies the boundary that opening charges nothing. It stops short of stating when not to use it versus revise_design or quote_order, so there is no routing rule if the customer only wants edits or pricing.

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