place_stop_limit_order

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

Without annotations, the description carries the full burden. It explains the order flow (stop triggers limit) and default time validity, but lacks details on failure conditions, fees, or side effects. For a financial tool, more behavioral context would be beneficial.

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 brief and front-loaded with the core purpose, followed by clear parameter definitions. Every sentence adds value without redundancy or 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 the absence of annotations and output schema, the description covers the essential behavior and parameters. It mentions return type 'Order' but lacks details on its structure. Still, it is mostly complete for a tool of this complexity.

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 Args section provides clear, concise descriptions for all five parameters, including default and enumeration for time_validity. This adds substantial meaning beyond the bare schema types and names, fully compensating for the 0% schema coverage.

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 the tool places a stop-limit order with a trigger and execution condition. It specifies the verb 'Place' and the resource 'stop-limit order', distinguishing it from sibling order types like market and limit orders.

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 explains the behavior when market price reaches stop price then executes at limit price, guiding usage for conditional orders. It does not explicitly exclude alternatives, but the mechanism is clearly described, allowing agents to infer appropriate use cases.

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