 # PR Impact Analysis
 
-A GitHub Action that automatically analyzes PR code changes via LLM, generates impact assessment and test recommendations, then creates a Jira issue assigned to QA.
+A GitHub Action that analyzes PR code changes and creates Jira QA issues. All analysis logic runs on a Cloudflare Worker — this action is a thin client that collects PR data and delegates.
 
 ## How It Works
 
 ```
-PR merged → Fetch diff → LLM analysis → Create Jira issue → Assign to QA
+PR merged → Fetch diff → POST to Worker → Worker returns result → Set outputs
 ```
 
 1. Fetches PR metadata and diff via GitHub API
-2. Sends diff to LLM (OpenAI-compatible API) for impact analysis
-3. Creates a Jira issue with structured test checklist and risk assessment
+2. Sends data to a Cloudflare Worker which handles:
+   - OK-XXXX Jira key detection (skip if already linked)
+   - GitHub → Jira user mapping + dedup search
+   - LLM impact analysis with duplicate detection
+   - Jira issue creation (if needed)

-## Switching LLM Provider
+## Worker Configuration
 
-Uses OpenAI-compatible `/v1/chat/completions` endpoint. Switch by changing inputs:
-
-```yaml
-# DeepSeek (default, cost-effective for testing)
-llm-api-base-url: https://api.deepseek.com
-llm-model: deepseek-chat
-
-# OpenAI
-llm-api-base-url: https://api.openai.com
-llm-model: gpt-4o
-
-# Groq
-llm-api-base-url: https://api.groq.com/openai
-llm-model: llama-3.1-70b-versatile
-```
-
-## Jira Issue Output
-
-The created Jira issue includes:
-
-- **Change summary** — one-line description of what changed
-- **Risk level** — high / medium / low with color indicators
-- **Affected modules** — list of impacted areas
-- **Test checklist** — actionable test steps (Jira task list format)
-- **Regression areas** — what else to regression test
-- **PR link** — direct link back to the merged PR
+LLM, Jira, and user mapping configuration lives in the Cloudflare Worker, not in this action. See the Worker project for setup details.

-- **依赖变更**：package.json、lock 文件变更，除非是核心依赖的大版本升级
-- **Patch 文件**：patches/ 目录下的变更
-- **纯工程改动**：CI/CD 配置、lint 规则、tsconfig、构建脚本、开发工具配置、Dockerfile 等
-- **文档**：README、CHANGELOG、注释、JSDoc
-- **代码格式化**：纯 formatting、import 排序等不影响运行时行为的变更
-- **纯类型定义**：仅 TypeScript 类型修改，不影响运行时逻辑
-- **测试代码**：仅修改测试文件，不涉及源码变更

-
-## 原则
-- 说人话，QA 能直接照着测
-- test_checklist 要具体到操作步骤，不要笼统的"测试XX功能"
-- risk_level 基于变更范围、是否涉及核心逻辑、是否有数据变更来判断
-- 如果 diff 被截断，基于文件名和可见部分做合理推断，并在 notes 里说明
-- 当 skip_qa 为 true 时，test_checklist 可以为空数组，但仍需填写 change_summary 和 risk_level

-- 禁止套话、禁止重复 PR 标题、禁止"可能会影响"之类的模糊表述

-- impact_analysis 直接说受影响的用户操作，如"用户在 Token 详情页可能看不到交易按钮"
-- affected_modules 只写模块名，不加描述

-## 不需要 QA 的变更（skip_qa: true）
-以下类型的变更通常不影响用户可见行为，不需要创建 QA 任务：
-- **国际化 (i18n)**：纯翻译文件的增删改（locale 相关），除非涉及关键业务文案的逻辑变更
-- **依赖变更**：package.json、lock 文件变更，除非是核心依赖的大版本升级
-- **Patch 文件**：patches/ 目录下的变更
-- **纯工程改动**：CI/CD 配置、lint 规则、tsconfig、构建脚本、开发工具配置、Dockerfile 等
-- **文档**：README、CHANGELOG、注释、JSDoc
-- **代码格式化**：纯 formatting、import 排序等不影响运行时行为的变更
-- **纯类型定义**：仅 TypeScript 类型修改，不影响运行时逻辑
-- **测试代码**：仅修改测试文件，不涉及源码变更
-
-## 需要 QA 的变更（skip_qa: false）
-- 用户可见的 UI / 交互变更
-- 业务逻辑修改
-- API 调用或数据流变更
-- 数据处理 / 存储逻辑变更
-- 权限 / 安全相关变更
-- 核心依赖的大版本升级
-
-## 原则
-- 说人话，QA 能直接照着测
-- test_checklist 要具体到操作步骤，不要笼统的"测试XX功能"
-- risk_level 基于变更范围、是否涉及核心逻辑、是否有数据变更来判断
-- 如果 diff 被截断，基于文件名和可见部分做合理推断，并在 notes 里说明
-- 当 skip_qa 为 true 时，test_checklist 可以为空数组，但仍需填写 change_summary 和 risk_level
-
-## 输出要求
-- 禁止套话、禁止重复 PR 标题、禁止"可能会影响"之类的模糊表述
-- change_summary 直接说动作+对象，如"Token 详情页底部按钮改为条件渲染"
-- impact_analysis 直接说受影响的用户操作，如"用户在 Token 详情页可能看不到交易按钮"
-- affected_modules 只写模块名，不加描述
-- diff 被截断时在 impact_analysis 末尾注明`;
