place_order

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

The description states 'This action will create a real order in the system', indicating irreversibility, which is important for a mutation tool. With no annotations, this carries the burden, but it lacks details on side effects like charges or inventory changes.

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 two sentences, front-loaded with the purpose, and includes an important note in all caps. Every word serves a purpose without redundancy.

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 the tool has no output schema, a description of the return value would be helpful but is missing. The description adequately covers the core function but lacks completeness about the aftermath of the order.

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?

The input schema has 100% coverage with descriptions for both parameters. The description adds the phrase 'one or more products' which aligns with the items parameter, but does not provide additional meaning beyond what is in the schema.

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 'Place an order for one or more products', using a specific verb and resource. It distinguishes itself from sibling tools, which are all read-only queries, by indicating a write operation.

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 explicitly instructs to 'Ask the user to confirm before placing an order', providing a clear usage guideline. However, it does not mention when not to use this tool or provide alternatives.

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