Supports six scenarios: list available coupons, search by coupon type, view expired/used history, view full coupon details, read usage rules, and trace coupon acquisition source. ## 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 | MCP Server | Status | |------------|--------| | Gate (main) | ✅ Required | ### MCP Tools Used **Query Operations (Read-only)** - cex_coupon_get_user_coupon_detail - cex_coupon_list_user_coupons ### Authentication - Credentials Source: Local Gate MCP deployment (`GATE_API_KEY`, `GATE_API_SECRET`) - API Key Required: Yes - Permissions: Coupon:Read - 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`](./references/mcp.md), then execute this skill's coupon-query workflow. - `SKILL.md` keeps coupon semantics, mapping rules, and rendering policy. - `references/mcp.md` is the authoritative MCP execution layer for list/detail query behavior and degradation-safe output. ## Domain Knowledge ### MCP Tool Mapping | Tool | Description | | ----------------------------------- | ------------------------------------------------------------- | | `cex_coupon_list_user_coupons` | Fetch user coupon list (paginated, filterable by type/status) | | `cex_coupon_get_user_coupon_detail` | Fetch full details of a single coupon | ### Coupon Types Reference > **IMPORTANT — Type Translation Rule**: When displaying the coupon type, map `coupon_type` strictly to the Display Name.

Identify user intent from the Routing Rules table above. 2. Load the corresponding reference document. 3. Follow the workflow in that document step by step. 4. All operations are read-only — no confirmation gate required. ## Error Handling | Situation | Action | | -------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------- | | Coupon not found | Coupon record does not exist or does not belong to current user. Ask user to re-check which coupon they meant; re-fetch list to get valid IDs. | | Invalid coupon type | `coupon_type` is not a recognized enum value. Map user's natural language to the Coupon Types Reference table and retry. | | No coupons returned | Inform user no coupons match the query. Suggest earning coupons through tasks, activities, or referrals. | | Coupon type unrecognized by user | User mentions a vague or informal name. Clarify by listing the closest matching type names from the Coupon Types Reference. | ## Safety Rules - All operations in this skill are **read-only** (query only, no writes). - Never request or expose user API secrets in the conversation. - Do not infer or guess coupon IDs — always obtain them from the list API first.
