place_order

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

The description does not disclose behavioral traits such as whether the order is executed immediately, if confirmations are required (only hinted via suppressConfirmations in examples), or what happens upon failure. With no annotations, this is insufficient.

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 at two sentences followed by examples. It is front-loaded with the purpose, and the examples are well-structured. A slight deduction for not being even more concise.

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 10 parameters, no output schema, and no annotations, the description should provide more context on return values, error handling, and workflow (e.g., need for confirmation). The examples only cover basic usage.

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?

Despite 0% schema description coverage, the examples illustrate the usage of 7 out of 10 parameters (accountId, symbol, action, orderType, quantity, price, stopPrice, suppressConfirmations). However, exchange and tif are not explained, leaving gaps.

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 explicitly states 'Place a trading order' which is a specific verb+resource combination. The examples further clarify the action, distinguishing it from sibling tools like confirm_order or get_order_status.

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?

No guidance is provided on when to use this tool versus alternatives such as confirm_order or create_alert. There is no mention of prerequisites, like requiring authentication or having sufficient funds.

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