movePosition

Destructive

Transfer positions between unified sub-accounts under the same master UID with no fees. Supports linear, inverse, spot, and option instruments in batches up to 25 legs.

Instructions

Transfer positions between two unified trading accounts (UIDs) without fees. Supports linear, inverse, spot, and option. Up to 25 legs per request. Both accounts must be under the same master account.

Agent hint: Use this to move positions between sub-accounts. Requires master API key. Both UIDs must be UTA. Futures must be in one-way mode. Max 25 legs per request. Price must be within 95%-105% of mark price for linear/inverse. No fees generated. Check status via getMovePositionHistory if response status is Processing.

A4.4/5.0
Behavior4/5

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

Annotations already mark this as destructive and non-read-only. The description supplements this with concrete constraints: no fees, max 25 legs, 95%-105% mark price requirement, async status processing, and master API key requirement. It does not contradict the annotations.

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

Conciseness3/5

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

Purpose and key constraints are front-loaded, but the description is repetitive: 'without fees'/'No fees generated' and 'Up to 25 legs'/'Max 25 legs' appear twice. It is still relatively compact and scannable, but the redundancy keeps it from a higher score.

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

Completeness4/5

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

For a complex mutation with no output schema, the description covers prerequisites, constraints, and async status handling via getMovePositionHistory. It could be clearer about the exact structure and required fields of the list parameter, but enough information is present for an agent to invoke it correctly.

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 only 25% (only confirm is described). The description compensates by explaining that fromUid/toUid are UIDs, list items represent legs, and by detailing supported categories and price limits. It doesn't fully document each field, but it adds meaningful context beyond the bare schema.

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 opens with a specific verb and resource: 'Transfer positions between two unified trading accounts (UIDs) without fees.' It also lists supported categories (linear, inverse, spot, option) and a 25-leg limit, clearly distinguishing this from status tools like getMovePositionHistory.

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

Usage Guidelines5/5

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

The 'Agent hint' explicitly states when to use the tool: 'Use this to move positions between sub-accounts.' It also provides clear prerequisites (master API key, UTA, one-way mode) and directs to getMovePositionHistory for status follow-up, giving solid guidance on selection and post-call behavior.

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