addReduceMargin

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

With no annotations, the description discloses return of updated position details including liqPrice, constraints on decimal places, and hedge mode requirement. No contradictions.

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?

Four sentences plus agent hint, front-loaded with action and mode, efficient and no redundant wording.

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?

Covers all essential aspects: purpose, parameter usage, return value, and constraints. Complete for a margin adjustment tool with no output schema.

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?

Given 0% schema coverage, description adds significant meaning: sign convention for margin, decimal limit, hedge mode for positionIdx, and example values.

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 adds or reduces margin for a position in isolated margin mode. It distinguishes from the sibling 'addMargin' by explicitly including both add and reduce operations.

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 clear instructions on using positive/negative values, decimal places, and hedge mode. Does not explicitly mention when not to use or alternative tools, but agent hint gives practical context.

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