place_order

Submit a buy or sell order by providing a compact command string that specifies the instrument, order type, quantity, and price for market or limit orders.

Instructions

Place a standard order (Market/Limit) using a command string like 'NIFTY 24500 CE 30 L 110'

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

B3.3/5.0
Behavior2/5

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

No annotations are provided, so the description must fully disclose behavioral traits. It only states 'Place a standard order' without describing side effects (e.g., execution timing, margin impact, order lifecycle), prerequisites, or error conditions. This is insufficient for a mutation operation.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence with an example, which is concise and front-loaded. However, it could be improved by separating the example and adding brief parameter explanations for better readability.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's mutation nature and lack of output schema or annotations, the description is too minimal. It fails to mention important context such as return format, login requirement, margin checks, or how to interpret the result. Compared to siblings, it does not clarify when this should be used over similar order tools.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% with minimal descriptions. The tool description adds a concrete example for the 'command' parameter ('NIFTY 24500 CE 30 L 110'), clarifying the expected format beyond the schema's 'Smart order string'. The 'buy_or_sell' parameter is not further elaborated, but the addition for 'command' is valuable.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action ('Place') and the resource ('standard order'), with specific order types (Market/Limit) and an example command string, distinguishing it from sibling tools like cancel_order or modify_order.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool versus alternative order placement tools (place_auto_sl, place_manual_sl) or when not to use it. Missing context like prerequisites (e.g., need to be logged in) or scenarios where this tool is appropriate.

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