place_order

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

With no annotations provided, the description carries full burden for behavioral disclosure but only states the action ('Place an order') without mentioning any behavioral traits. It doesn't indicate whether this is a read-only or destructive operation, what permissions are required, whether it's idempotent, what happens on failure, or any rate limits or side effects.

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 maximally concise with just two words. While this represents under-specification rather than ideal conciseness, it contains zero wasted words and is perfectly front-loaded with the core action.

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 complex financial trading tool with 15 parameters, 7 required parameters, no annotations, and no output schema, the two-word description is completely inadequate. It doesn't explain what happens after order placement, what the response contains, error conditions, or any context about the trading system it interacts with.

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?

With 100% schema description coverage, the baseline is 3. The description adds no parameter information beyond what's already documented in the comprehensive schema, which includes detailed descriptions for all 15 parameters including enums, defaults, and constraints.

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 'Place an order' is a tautology that merely restates the tool name without adding specificity. It doesn't explain what type of order (financial/trading order), what resource it acts upon, or how it differs from sibling tools like modify_order or cancel_order.

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 absolutely no guidance about when to use this tool versus alternatives. With sibling tools like modify_order, cancel_order, and get_orders available, there's no indication of when this creation tool is appropriate versus modification or query tools.

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