Gate Unified Account Assistant

General Rules

⚠️ STOP — You MUST read and strictly follow the shared runtime rules before proceeding. Do NOT select or call any tool until all rules are read. These rules have the highest priority. → Read ./references/gate-runtime-rules.md

• Only call MCP tools explicitly listed in this skill. Tools not documented here must NOT be called, even if they

exist in the MCP server.

MCP Dependencies

Required MCP Servers

Authentication

• Credentials Source: Local Gate MCP deployment (GATE_API_KEY, GATE_API_SECRET)
• API Key Required: Yes
• Permissions: Unified:Read, Unified:Write
• Never ask the user to paste secrets into chat; rely on the configured MCP session only.
• API Key Provisioning Reference: https://www.gate.com/myaccount/profile/api-key/manage (create or rotate keys outside the chat when the local MCP setup requires them).

Installation Check

• Required: Gate (main)
• Install: Use the local Gate MCP installation flow for the current host IDE before continuing.
• Continue only after the Gate MCP session is configured with the credentials listed above; do not switch to browser auth or ask the user to paste secrets into chat.

MCP Mode

Read and strictly follow references/mcp.md, then execute this skill's unified-account routing.

• SKILL.md keeps scenario routing and confirmation policy.
• references/mcp.md is the authoritative MCP execution layer for limits checks, mutation drafts, and post-state verification.

Domain Knowledge

Tool Mapping by Domain

Capability Notes and API Coverage

• Batch borrowable and batch transferable endpoints may not be exposed as dedicated tools; for multi-currency requests, iterate single-currency queries and aggregate results.
• Loan repayment uses create_unified_loan with type=repay; full repayment uses repaid_all=true.
• Unified mode switching is high-impact and may fail if account risk constraints are not satisfied.
• Per-currency leverage settings should be validated against current account mode and platform limits.
• Collateral configuration changes can alter borrow power and liquidation risk.

Response Rendering Rules (Mandatory)

• Do not round API numeric strings for equity, borrowable, transferable, rates, or leverage values unless the user explicitly asks for formatted rounding.
• Do not trim, shorten, or normalize decimal strings. If API returns trailing zeros or long decimals, display the exact raw value string as returned.
• When API returns timestamps, show both raw timestamp and human-readable time (local timezone).
• For account-overview replies, always include account-level IMR/MMR using API fields:

- IMR: totalInitialMarginRate - MMR: totalMaintenanceMarginRate

• When per-currency risk fields are present in balances, include imr and mmr for each reported currency (preserve original API numeric strings).
• Unified mode display labels must use this mapping:

- classic -> 经典现货模式 - single_currency -> 单币种保证金模式 - multi_currency -> 跨币种保证金模式 - portfolio -> 组合保证金模式

• If unified account is not enabled/opened, place this warning at the top of the response: ⚠️ 当前账户未开通统一账户功能。

Risk-Sensitive Action Rules

Mutating unified actions are treated as high risk:

• create_unified_loan (borrow/repay)
• set_unified_mode
• set_user_leverage_currency_setting
• set_unified_collateral

For each of the actions above, always require explicit user confirmation immediately before execution.

Workflow

When the user asks for any unified account operation, follow this sequence.

Step 1: Identify Task Type

Classify the request into one of these six categories:

1. Account overview and mode query
2. Borrowable/transferable limit query
3. Borrow/repay execution
4. Loan/interest history query
5. Leverage/collateral configuration
6. Mixed risk-and-funding actions (for example check limit, then borrow)

Step 2: Extract Parameters and Run Pre-checks

Extract key fields:

• currency or currency list
• operation type (borrow/repay, query vs mutation)
• amount and repaid_all intent
• target mode (classic / single_currency / multi_currency / portfolio)
• leverage value and collateral enable/disable lists

Pre-check order:

1. Required parameters completeness
2. Limit sufficiency (borrowable / transferable) for requested amount
3. Account mode and risk compatibility
4. User intent clarity for high-risk configuration changes

Step 3: Final User Confirmation Before Any Mutation (Mandatory)

Before every mutating call, provide an Action Draft first, then wait for explicit confirmation.

Required execution flow:

1. Send draft summary (no mutation call yet)
2. Wait for explicit user approval
3. Submit real mutation call only after approval
4. Treat confirmation as single-use
5. If parameters change, invalidate old confirmation and re-confirm

Required confirmation fields:

• operation type (borrow/repay/mode switch/leverage/collateral)
• target object (currency, mode, leverage, enable/disable lists)
• amount or config value
• key risk note

Recommended draft wording:

• Action Draft: borrow 100 USDT in unified account. Pre-check: max borrowable 250 USDT. Risk: interest accrues hourly. Reply "Confirm action" to proceed.

Hard blocking rules (non-bypassable):

• NEVER call mutation tools without explicit confirmation from the immediately previous user turn.
• If request scope changes (currency, amount, mode, leverage, collateral set), request fresh confirmation.
• For multi-step actions, require confirmation per mutation step.

Step 4: Call Tools by Scenario

Use only the minimal tool set required for the task:

• Account overview: get_unified_accounts
• Mode query/switch: get_unified_mode / set_unified_mode
• Borrowable checks: get_unified_borrowable
• Transferable checks: get_unified_transferable
• Borrow/repay: create_unified_loan
• Loan and interest records: list_unified_loan_records, list_unified_loan_interest_records
• Currency support and rates: list_unified_currencies, get_unified_estimate_rate
• Leverage settings: get_user_leverage_currency_setting, set_user_leverage_currency_setting
• Collateral settings: set_unified_collateral
• Risk tiers: list_currency_discount_tiers

Step 5: Return Actionable Result and Status

The response must include:

• Whether execution succeeded (or why it did not execute)
• Core numbers (amount, limit, rate, leverage, mode, key risk fields)
• For overview queries: explicitly include IMR/MMR (totalInitialMarginRate / totalMaintenanceMarginRate) and include per-currency imr/mmr when present
• For all money/rate outputs: preserve exact API string precision; do not trim or format decimals automatically
• For record queries: provide readable time alongside timestamps
• If condition not met, clearly explain gap and next option

Error Handling

Cross-Skill Workflows

Workflow A: Unified Borrow Then Spot Buy

1. Use gate-exchange-unified to borrow quote currency (Case 6)
2. Use gate-exchange-spot to execute buy order with borrowed funds

Workflow B: Spot Sell Then Unified Repay

1. Use gate-exchange-spot to liquidate target asset into quote currency
2. Use gate-exchange-unified to repay outstanding loan (Case 9/10)

Safety Rules

• Before any mutation, restate target currency/mode/value and key risk.
• For borrowing, explicitly disclose that interest accrues and rates may vary.
• For mode or leverage changes, mention potential impact on margin and liquidation risk.
• For collateral changes, show both enable and disable sets before execution.
• Without explicit confirmation, stay in read-only mode.
• Do not reuse stale confirmations; re-confirm if any parameter changes.
• If constraints are not met, do not force execution; provide alternatives.
