MCP Mode

Read and strictly follow references/mcp.md, then execute this skill's Simple Earn workflow.

• SKILL.md keeps routing and business constraints.
• references/mcp.md is the authoritative MCP execution layer for query/action separation, confirmation gates, and post-action verification.

Trigger Conditions

Activate this skill when the user expresses any of the following intents:

• Simple Earn, Uni, flexible earn, fixed earn, fixed-term, subscribe, redeem, positions, interest, top APY
• Any request involving Simple Earn subscribe, redeem, position query, interest query, fixed-term product list, or fixed-term history query

Prerequisites

• MCP Dependency: Requires gate-mcp to be installed.
• Authentication: Position and write operations require API key authentication; rate and currency queries are public.
• Disclaimer: Always append when showing APY or rates: "This information is for reference only and does not constitute investment advice. APY may change. Please understand the product terms before subscribing."

Supported Workflows

Flexible (Uni)

• Single-currency or all positions query
• Single-currency interest query
• Estimated APY query
• Subscribe (lend), redeem, and change min rate operations with user confirmation

Fixed-term

• Product list and product list by currency
• Subscribe and early redeem with user confirmation
• Current total positions and single-order detail queries
• History queries for subscribe, redeem, interest, and extra bonus

Routing Rules

Flexible requests

| Case | User Intent | Signal Keywords | Action | |------|-------------|-----------------|--------| | 1 | Subscribe (lend) | "subscribe", "lend to Simple Earn" | Collect currency/amount/min_rate and confirm, then call cex_earn_create_uni_lend with type: lend. | | 2 | Redeem | "redeem", "redeem from Simple Earn" | Collect currency/amount and confirm, then call cex_earn_create_uni_lend with type: redeem. | | 3 | Single-currency position | "my USDT Simple Earn", "position for one currency" | See references/scenarios.md flexible scenario section | | 4 | All positions | "all Simple Earn positions", "total positions" | See references/scenarios.md flexible scenario section | | 5 | Single-currency interest | "interest", "USDT interest" | See references/scenarios.md flexible scenario section | | 6 | Subscribe top APY | "top APY", "one-click subscribe top APY" | Show top APY via cex_earn_list_uni_rate, ask confirmation, then call cex_earn_create_uni_lend. | | 7 | Change lend settings (e.g. min rate) | "change min_rate", "change Simple Earn settings" | Collect currency/min_rate and confirm, then call cex_earn_change_uni_lend. | | 8 | Auth failure (401/403) | MCP returns 401/403 | Do not expose keys; prompt user to configure Gate CEX API Key (earn). |

Fixed-term requests

| Case | User Intent | Signal Keywords | Action | |------|-------------|-----------------|--------| | 1 | All fixed-term products | "fixed-term products" | See references/scenarios.md fixed-term section 1 and references/fixed-earn-mcp-tools.md §1 | | 2 | Fixed-term products by currency | "USDT fixed-term products" | See references/scenarios.md fixed-term section 2 and references/fixed-earn-mcp-tools.md §2 | | 3 | Fixed-term subscribe | "subscribe 1 SOL fixed-term" | Collect currency/amount/term and confirm, then call cex_earn_create_earn_fixed_term_lend. | | 4 | Fixed-term early redeem | "redeem order 5862443199" | Collect order_id and confirm, then call cex_earn_create_earn_fixed_term_pre_redeem. | | 5 | Fixed-term total positions | "total fixed-term positions", "current total fixed-term position amount" | Call cex_earn_list_earn_fixed_term_lends with order_type: "1", page, and limit. | | 6 | Single fixed-term order detail | "order 5862443199" | Call cex_earn_list_earn_fixed_term_lends with order_type: "1" and order_id. | | 7 | Fixed-term history | "subscription records", "redeem records", "interest records" | Call cex_earn_list_earn_fixed_term_history with type, page, limit, and optional time range. | | 8 | Compliance / region restriction | region restriction questions | Return the standard compliance error message if the API rejects the request. | | 9 | Compliance check failure | compliance validation failed | Do not retry or expose internal logic; return the API error message when available. |

Execution

1. Identify user intent from the routing rules above.
2. For flexible subscribe/redeem/top APY and fixed-term subscribe/early redeem: collect required params, confirm with the user, then call the corresponding MCP tool.
3. For flexible or fixed-term read-only queries: read the matching scenario section in references/scenarios.md and follow the workflow there.
4. For auth failures: do not expose API keys or raw errors; prompt the user to configure API key / log in again.
5. If the intent is ambiguous, ask a clarifying question before routing.

Domain Knowledge

Flexible (Uni)

• Subscribe (lend) means the user lends a specified amount of a currency to the Simple Earn pool.
• Redeem means the user redeems a specified amount from the pool.
• min_rate is the minimum acceptable hourly rate for the currency; required for lend.
• Settlement windows: lend and redeem are not allowed in the two minutes before and after each whole hour (use for errors/logic only; do not surface specific clock times or timestamps to the user unless the user explicitly asks when settlement applies).
• User-facing display (flexible only): In any reply based on flexible Uni MCP data, do not show time-related fields—omit timestamps, dates, time-of-day, countdowns, chart time axes, history operation times, and any API field whose purpose is when something occurred. Show only non-time facts (currency, amounts, balances, rates/APY, interest_status, success/failure). If a tool returns only time-series data (e.g. APY chart), summarize without timestamps (e.g. latest estimated APY only) or skip the series.

Fixed-term

• Subscribe uses only products with status=2 (subscribing) and show_status=2 (visible).
• Product list queries can be filtered by currency and product type.
• Fixed-term positions and history should be presented using the table formats defined in references/scenarios.md and references/fixed-earn-mcp-tools.md.
• Early redeem uses the fixed-term order ID and returns the redeemed principal.

Safety Rules

• Always confirm currency, amount, and min_rate (for flexible lend) or currency/amount/term (for fixed-term subscribe) before calling write MCPs.
• Always confirm order_id before calling fixed-term early redeem.
• Do not recommend specific currencies or predict rates.
• Never expose API keys, internal endpoint URLs, or raw error traces to the user.
• Reject negative or zero amounts; validate that the currency is supported.

Error Handling

| Condition | Response | |-----------|----------| | Auth endpoint returns 401/403 | "Please configure your Gate CEX API Key in MCP with earn/account permission." Do not expose keys or internal details. | | Flexible subscribe/redeem or fixed-term write request fails validation | Validate inputs, confirm details, then call the corresponding write tool. | | Position or history query fails | "Unable to load positions/history. Please check your API key has earn/account read permission." | | Empty positions or no rate data | "No positions found." / "No rate data available at the moment." |
