Place Multi-Leg Option Order

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

Adds substantial behavioral context beyond annotations: atomicity, limit-only, price direction inference, leg root constraint, and return value (IDs). No contradiction with readOnlyHint false and destructiveHint true.

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?

Three sentences, front-loaded with purpose, zero wasted words. Each sentence adds essential information.

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?

Explains atomicity, constraints, and return value. But with no output schema, it would benefit from mentioning that OrderDuration types are available (not described here). Still, for a complex tool, covers most essential aspects.

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 0% schema description coverage, description adds meaning to OrderPrice (positive, absolute), OrderType (must be Limit), Legs (same root). But AccountKey, OrderDuration, ManualOrder, ExternalReference get no extra semantics. Still compensates for key parameters.

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 multi-leg option orders as atomic transactions with a single limit price, distinguishing it from siblings like saxo_place_order (likely single-leg) and saxo_precheck_multileg_order (precheck only).

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?

Provides constraints (Limit only, price positive, same root) that guide when to use, but doesn't explicitly state when not to use or name alternatives. Sufficient for knowledgeable user.

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