Use when the user asks to borrow crypto against collateral or manage existing loans. Triggers on 'collateral loan', 'current loan', 'fixed loan', 'repay', 'add collateral', 'redeem collateral'." --- # Gate Exchange Multi-Collateral Loan Skill ## 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 [gate-runtime-rules.md](https://github.com/gate/gate-skills/blob/master/skills/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 | MCP Server | Status | |------------|--------| | Gate (main) | ✅ Required | ### MCP Tools Used **Query Operations (Read-only)** - cex_mcl_get_multi_collateral_current_rate - cex_mcl_get_multi_collateral_fix_rate - cex_mcl_get_multi_collateral_ltv - cex_mcl_get_multi_collateral_order_detail - cex_mcl_list_multi_collateral_orders - cex_mcl_list_multi_collateral_records - cex_mcl_list_multi_repay_records - cex_mcl_list_user_currency_quota - cex_mcl_operate_multi_collateral **Execution Operations (Write)** - cex_mcl_create_multi_collateral - cex_mcl_repay_mcl ### Authentication - API Key Required: Yes (see skill doc/runtime MCP deployment) - Permissions: Mcl:Write - Get API Key: https://www.gate.io/myaccount/profile/api-key/manage ### Installation Check - Required: Gate (main) - Install: Run installer skill for your IDE - Cursor: `gate-mcp-cursor-installer` - Codex: `gate-mcp-codex-installer` - Claude: `gate-mcp-claude-installer` - OpenClaw: `gate-mcp-openclaw-installer` ## MCP Mode **Read and strictly follow** [`references/mcp.md`](./references/mcp.md), then execute this skill's collateral-loan workflow. - `SKILL.md` keeps routing and product constraints. - `references/mcp.md` is the authoritative MCP execution layer for quota/LTV pre-checks, confirmation gates, and post-action verification. ## Trigger Conditions This skill activates when the user asks about multi-collateral loan operations. Classify intent via **Routing Rules** (Cases 1–7). Trigger phrases include: "collateral loan", "current loan", "fixed loan", "repay", "add collateral", "redeem collateral", or equivalent in other languages. ## Workflow ### Step 1: Classify intent Identify the user intent using Routing Rules (Cases 1–7). If required inputs are missing (order_id, currency, amount, fixed term), ask clarifying questions before proceeding. ### Step 2: Read-only requests (rates, LTV, quota, orders) Call the corresponding MCP tool when the user asks for rates, LTV, quota, order list, or order detail. Call [REDACTED_SECRET] with: - `type`: `collateral` or `borrow` - `currency`: comma-separated (borrow: single currency) Call [REDACTED_SECRET] with: - (no params) Call [REDACTED_SECRET] with: - (no params) Call [REDACTED_SECRET] with: - `currencies`: comma-separated currency list Call [REDACTED_SECRET] with: - `page`, `limit` (optional) - `sort` (optional): `time_desc`, `ltv_asc`, `ltv_desc` - `order_type` (optional): `current` or `fixed` Call [REDACTED_SECRET] with: - `order_id` Key data to extract: - LTV thresholds, fixed/current rates, quota rows, order_id, order status, collateral and borrow details ### Step 3: Create loan (current or fixed) If current loan: 1) Build draft (collateral list + borrow currency/amount). 2) Ask for confirmation. 3) Call `cex_mcl_create_multi_collateral` with **`order`**: JSON string (borrow_currency, borrow_amount, collateral_currencies, order_type: current). If fixed loan: 1) Call [REDACTED_SECRET] (returns a **list**); **filter by borrow_currency**; take `rate_7d` or `rate_30d` as **fixed_rate** (hourly rate; pass through unchanged, do not convert or relabel as annual/daily). 2) Build draft with fixed_type and fixed_rate (describe to user as hourly rate if showing). 3) Ask for confirmation. 4) Call `cex_mcl_create_multi_collateral` with **`order`**: JSON including order_type: fixed, fixed_type `7d`/`30d`, fixed_rate. ### Step 4: Repay Build draft, ask confirmation, then call `cex_mcl_repay_mcl` with: - **`repay_loan`**: JSON string with `order_id` and `repay_items` [{ currency, amount, repaid_all }] ### Step 5: Add or redeem collateral Build draft, ask confirmation, then call [REDACTED_SECRET] with: - **`collateral_adjust`**: JSON string with `order_id`, `type` (`append` | `redeem`), `collaterals` [{ currency, amount }] ## Judgment Logic Summary - Determine case by keywords and required inputs (loan create / repay / add / redeem / list). - Fixed loan requires fix_rate lookup; if not available, stop and inform user. - All write operations must be confirmed before calling MCP. - Auth failure (401/403) prompts API key configuration. ## Report Template **When asking for confirmation**: Draft: - Type: {current|fixed|repay|append|redeem} - Order ID: {order_id if applicable} - Borrow: {borrow_amount} {borrow_currency} - Collateral: {collateral_amounts} - Fixed term/rate: {fixed_type} / {fixed_rate} (hourly rate) Please confirm to proceed. **On success**: - Summary of action and key identifiers (order_id, amounts). **On failure**: - Error message and next-step guidance (e.g., check currency/amount/LTV). ## Prerequisites - **MCP Dependency**: Requires [gate-mcp](https://github.com/gate/gate-mcp) to be installed. - **Authentication**: Order list, detail, repay, collateral, quota, and records require API key; LTV, fix rate, and current rate are public without key. - **Disclaimer**: Loan and LTV information is for reference only and does not constitute investment advice. Understand product terms and liquidation risk before borrowing. ## Available MCP Tools | Tool | Auth | Description | Reference | |------|------|-------------|-----------| | [REDACTED_SECRET] | No | 7d/30d fixed rates (list) | `references/mcl-mcp-tools.md` | | [REDACTED_SECRET] | No | LTV thresholds | `references/mcl-mcp-tools.md` | | [REDACTED_SECRET] | No | Current rates | `references/mcl-mcp-tools.md` | | [REDACTED_SECRET] | Yes | Borrow/collateral quota | `references/mcl-mcp-tools.md` | | `cex_mcl_create_multi_collateral` | Yes | Create loan (`order` JSON) | `references/mcl-mcp-tools.md` | | [REDACTED_SECRET] | Yes | List orders | `references/mcl-mcp-tools.md` | | [REDACTED_SECRET] | Yes | Order detail | `references/mcl-mcp-tools.md` | | `cex_mcl_repay_mcl` | Yes | Repay (`repay_loan` JSON) | `references/mcl-mcp-tools.md` | | [REDACTED_SECRET] | Yes | Add/redeem collateral (`collateral_adjust` JSON) | `references/mcl-mcp-tools.md` | | [REDACTED_SECRET] | Yes | Repay history | `references/mcl-mcp-tools.md` | | [REDACTED_SECRET] | Yes | Collateral history | `references/mcl-mcp-tools.md` | ## Routing Rules | Case | User Intent | Signal Keywords | Action | |------|-------------|-----------------|--------| | 1 | Create current loan | "current loan", "pledge ... borrow ... (current)" | See `references/scenarios.md` Scenario 1 | | 2 | Create fixed loan | "fixed loan", "borrow ... for 7/30 days" | See `references/scenarios.md` Scenario 2 | | 3 | Repay | "repay", "repay order ..." | See `references/scenarios.md` Scenario 3 | | 4 | Add collateral | "add collateral", "add margin" | See `references/scenarios.md` Scenario 4 | | 5 | Redeem collateral | "redeem collateral", "reduce margin" | See `references/scenarios.md` Scenario 5 | | 6 | List orders / order detail | "loan orders", "order detail", "my orders" | [REDACTED_SECRET] / [REDACTED_SECRET] — **never include any time/date fields** in the user-facing reply (see Presentation below) | | 7 | Auth failure (401/403) | MCP returns 401/403 | Do not expose keys; prompt user to configure Gate CEX API Key (multi-collateral loan). | ## Execution 1. Identify user intent from the Routing Rules table above. 2. For Cases 1–5: Read the corresponding scenario in `references/scenarios.md` and follow the Workflow (show order draft, then call MCP only after user confirmation). 3. For Case 6: Call list or detail tool as needed; no confirmation required for read-only. **Never show** borrow_time, maturity, due date, operate_time, create_time, repay_time, Unix timestamps, or any other time-related fields in the reply—even if the user asks for dates/times; suggest checking the Gate app or web for timing details. 4. For Case 7: Do not expose API keys or raw errors; prompt the user to set up Gate CEX API Key with multi-collateral loan permission in MCP. 5. If the user's intent is ambiguous (e.g. missing order_id, currency, or amount), ask a clarifying question before routing. ## Domain Knowledge ### Core Concepts - **Current loan**: Flexible loan. Create via `cex_mcl_create_multi_collateral` with `order` JSON: `order_type: current`. - **Fixed loan**: 7-day/30-day. `order` JSON must include `order_type: fixed`, **`fixed_type`**: `7d` or `30d` (lowercase), **`fixed_rate`**: **hourly interest rate** from [REDACTED_SECRET] (use `rate_7d` or `rate_30d` for that borrow_currency; pass as-is, do not describe as annual or daily rate). Missing fixed fields may yield INVALID_PARAM_VALUE. - **Repay**: `cex_mcl_repay_mcl` with `repay_loan` JSON. - **Add collateral**: [REDACTED_SECRET], `collateral_adjust` with `type: append`. - **Redeem collateral**: same tool, `type: redeem`. - **LTV**: [REDACTED_SECRET] — init_ltv, alert_ltv, liquidate_ltv. ### Create Loan Flow (Case 1 & 2) 1. Parse collateral, borrow currency/amount; fixed: 7 days → **7d**, 30 days → **30d**. 2. **Current**: Optionally [REDACTED_SECRET] or current rate tools. On confirm: `cex_mcl_create_multi_collateral` with `order` JSON. 3. **Fixed**: [REDACTED_SECRET]; filter list by borrow_currency; on empty or no row, stop with user message; else set **fixed_rate** = rate_7d or rate_30d (**hourly rate**; pass as-is into order JSON; do not describe as annual or daily). On confirm: `order` JSON with fixed fields. ### Repay Flow (Case 3) 1. Parse order_id and repay amount (or full). 2. Show draft; on confirm: `cex_mcl_repay_mcl` with `repay_loan` JSON. ### Add / Redeem Collateral Flow (Case 4 & 5) 1. Parse order_id and collateral amount/currency. 2. Show draft; on confirm: [REDACTED_SECRET] with `collateral_adjust` JSON. ### Presentation — order list / order detail (Case 6) When the user asks to view **my collateral loan orders** or order detail: - **No time fields**: Do not output any time or date information—omit every timestamp-style field from MCP (e.g. `borrow_time`, maturity, due time, `operate_time`, `create_time`, `repay_time`, calendar dates, Unix seconds as dates). Do not paraphrase relative timing (e.g. "expires in 3 days") computed from those fields. - **Allowed in reply**: `order_id`, `status`, borrow side (currency, principal/interest left), collateral side (currency, amount), current LTV if present, fixed_type `7d`/`30d` as **term label only** (no calendar dates). - **If the user asks specifically for dates/maturity**: Reply that timing is not shown here and they should open Gate (app/web) for full order schedule—still do not paste API time fields into chat. ## Safety Rules - **Writes** (`cex_mcl_create_multi_collateral`, `cex_mcl_repay_mcl`, [REDACTED_SECRET]): Always require explicit confirmation and an order draft before execution. - **No investment advice**: Present LTV/rates; user decides. - **Sensitive data**: Never expose API keys or raw internal errors. - **Amounts**: Reject non-positive amounts; validate order_id for repay/collateral ops. - **Order views**: Never surface time columns, dates, or timestamp fields in order list/detail answers to the user. ## Error Handling | Condition | Response | |-----------|----------| | 401/403 | "Please configure your Gate CEX API Key in MCP with multi-collateral loan permission." | | `cex_mcl_create_multi_collateral` fails | Check `order` JSON: borrow fields; for fixed include fixed_type `7d`/`30d` and fixed_rate from fix_rate tool. | | Wrong fixed_type | Must be **`7d`** or **`30d`**, lowercase. | | Fix rate empty (fixed) | "Fixed rate temporarily unavailable; try later or use current loan." | | Repay / operate fails | Check order_id, currency, amount in JSON payloads. | | Order not found | "Order not found." / "No loan orders." | ## Prompt Examples & Scenarios See `references/scenarios.md` for prompt examples and expected behaviors (create current/fixed, repay, add collateral, redeem collateral).
