confirm_order

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

With no annotations, the description must carry the behavioral burden. It does state 'This submits the order,' implying a finalizing, likely irreversible action, and it notes prerequisites. However, it does not disclose side effects such as whether the cart is cleared, whether the order can be changed after submission, or what happens if the cart is empty.

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 main description is two clear sentences followed by concise Args and Returns sections. The Returns line is somewhat redundant given an output schema exists, but the overall length is appropriate and information is front-loaded. No fluff.

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 an output schema exists and this is a simple one-parameter tool, the description covers the essential prerequisites, the workflow order, and parameter meaning. It could be more explicit about the consequences of submitting (e.g., irreversibility, cart clearing), but it is largely sufficient for correct invocation.

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 description coverage is 0%, so the description fully compensates. The Args section explains the sole parameter: 'profile: Profile name (e.g. "child1"). Optional if only one profile is configured.' This provides type, an example, and conditionality that the schema lacks.

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?

Clearly states 'Confirm and finalize all items currently in the shopping cart' and 'This submits the order.' This is a specific verb (confirm/finalize) and resource (the shopping cart/order). It is easily distinguished from siblings like add_to_cart, get_cart_status, and remove_meal, as it is the final submission step.

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 provides workflow context: 'Items must first be added with add_to_cart. Call get_cart_status first to verify what will be ordered.' This tells the agent when to use this tool relative to sibling alternatives and mentions a prerequisite check.

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