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

With no annotations provided, the description carries the full responsibility for disclosing behavior. It explicitly states the safe dry-run default, the confirm flag for real orders, and the SBP limitation requiring card for auto-ordering. This is excellent transparency for a mutation tool.

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 and well-structured, front-loading the core purpose and critical default behavior. Each sentence adds unique value, with emphasis on important warnings via capitalization. No wasted words.

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?

Given that this is a mutation tool with no output schema or annotations, the description covers the essential aspects: purpose, default behavior, confirmation flag, payment selection, and a crucial limitation. It doesn't mention return values or preconditions like cart non-empty, but the coverage is strong for the tool's complexity.

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 baseline is 3. The description adds value by clarifying that confirm=false is a dry-run (reaching the pay button without confirming) and explaining the payment method caveat with SBP. This goes beyond the schema's basic type descriptions.

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 clearly states the tool's purpose: places an order from the cart. It uses a specific verb and resource, distinguishing it from sibling tools like add_to_cart or view_cart.

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?

The description provides clear context for usage: it explains the default dry-run behavior and how to make a real order via confirm=true. It also directs to list_payment_methods for payment selection. While it doesn't explicitly name alternative tools for when not to use this tool, the sibling context makes this clear.

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