### **项目：LLM辅助的自验证式代码反向工程框架**

**项目代号：** Athena-Reconstructor

**核心理念：** 我们不再仅仅“转译”代码，而是要**“重建功能等价物”**。最终产出的代码不需要在文本上与原始代码一模一样（这是不可能的），但必须在功能、接口和行为上完全一致。成功的标准是**通过一个我们自己生成的、完整的自动化测试套件**。

**施工AI：** Athena (一个具备代码生成、测试、调试和自我修正能力的AI程序员)

### **通用工作流程框架**

Athena将遵循一个包含“生成-验证-修正”循环的五阶段流程。

#### **阶段一：环境初始化与目标锁定 (Setup & Acquire)**

**目标：** 建立一个结构化的工作空间，并隔离待逆向的二进制文件。

* **步骤 1.1: 创建标准工作区**
    * 指令：`Create a directory structure for a new reverse engineering project: /source, /build, /specs, /tests.`
    * `source`：存放待逆向的二进制文件。
    * `build`：存放最终生成的、可读的源代码项目。
    * `specs`：存放分析阶段生成的规格和计划文档。
    * `tests`：存放用于验证的测试代码和工具。

* **步骤 1.2: 目标获取**
    * 指令：`Acquire the target package '@anthropic-ai/claude-code' via npm. Isolate the primary executable artifact, which is 'cli.mjs', and place it in the /source directory. Sanitize this file by removing all top-level comments to prevent safety-policy interference.`

---

#### **阶段二：架构分析与测试计划生成 (Analyze & Plan)**

**目标：** 不仅是理解软件功能，更是要产出一份可执行的、用于验收的**测试计划**和一份高级架构蓝图。

* **步骤 2.1: 生成高级架构规范 (High-Level Spec)**
    * 指令：`Analyze the source artifact at /source/cli.mjs. Generate a high-level architectural specification document and save it as /specs/ARCHITECTURE.md. This document must detail: 1. Core functional domains (e.g., AI, Codebase, Terminal, FileOps). 2. The primary data structures and their schemas. 3. The main control flows and user-facing commands. 4. Identify and list all external dependencies and their roles.`

* **步骤 2.2: 生成自动化测试计划 (Test Plan)**
    * 指令：`Based on /specs/ARCHITECTURE.md, create a comprehensive Test Plan and save it as /specs/TEST_PLAN.md. For each functional domain, define a suite of unit tests and integration tests. Each test case must be described with: 1. A unique ID. 2. The function/module to be tested. 3. The precise input conditions. 4. The expected output or state change. 5. Test type (Unit, Integration).`
    * **示例 (TEST_PLAN.md 中的条目):**
        ```markdown
        - **Test ID:** CMD-EDIT-001
        - **Module:** `commands/handlers/edit.ts`
        - **Description:** Test the 'edit' command on a specified file.
        - **Input:** Command: `edit src/index.ts`, Instruction: "add a console log 'hello world'".
        - **Expected Output:** The file `src/index.ts` content is modified to include `console.log('hello world');`.
        - **Type:** Integration
        ```

---

#### **阶段三：测试驱动的项目骨架生成 (Test-Driven Scaffolding)**

**目标：** 在编写任何功能代码之前，先将测试计划转化为可执行的、但当前会失败的测试代码。

* **步骤 3.1: 创建项目基础文件**
    * 指令：`In the /build directory, initialize a standard TypeScript project with a 'package.json' and 'tsconfig.json'.`

* **步骤 3.2: 生成空的实现文件 (Implementation Skeletons)**
    * 指令：`Based on the file structure defined in /specs/ARCHITECTURE.md, create an empty directory and file structure within /build/src/.`

* **步骤 3.3: 生成可执行的测试代码 (Test Skeletons)**
    * 指令：`Translate the /specs/TEST_PLAN.md into executable test files within a /build/tests/ directory. Use a testing framework like Jest or Vitest. Each test file should correspond to a module in /build/src/, and each test case from the plan should become a test function. At this stage, all tests are expected to fail because the implementation is empty. This creates our 'Validation Harness'.`
    * **示例 (build/tests/commands/edit.test.ts):**
        ```typescript
        import { handleEditCommand } from '../../src/commands/handlers/edit';
        import * as fs from 'fs/promises';

        describe('Edit Command Handler', () => {
          test('CMD-EDIT-001: should apply an edit to a file', async () => {
            // Setup: create a dummy file
            const filePath = 'dummy.ts';
            await fs.writeFile(filePath, 'const x = 1;');

            // Execute
            await handleEditCommand(filePath, "change const to let");

            // Verify
            const content = await fs.readFile(filePath, 'utf-8');
            expect(content).toContain('let x = 1;');

            // Teardown
            await fs.unlink(filePath);
          });
        });
        ```

#### **阶段四：迭代式实现与自修正循环 (Implement & Self-Correct)**

**目标：** 逐个模块地生成功能代码，并利用之前创建的测试套件进行实时验证和自动修复，直到所有测试通过。

* **核心循环指令 (The Athena Loop):**
    * `Start the implementation loop. For each module defined in /specs/ARCHITECTURE.md:`
    1.  `**Select Target:** Choose the next unimplemented module (e.g., 'src/fileops/reader.ts').`
    2.  `**Generate Implementation:** Analyze the binary at /source/cli.mjs and the corresponding requirements in /specs/ARCHITECTURE.md. Generate the full TypeScript code for the target module.`
    3.  `**Execute Tests:** Run the specific test file associated with this module (e.g., 'tests/fileops/reader.test.ts').`
    4.  `**Analyze & Refine (Self-Correction):**`
        * `**IF** all tests for the module pass, mark the module as 'COMPLETE' and proceed to the next one.`
        * `**ELSE (if tests fail):**`
            * `Analyze the test failure logs (stack trace, error messages, output diffs).`
            * `Correlate the failure with the code you just generated.`
            * `Identify the logical error, missing dependency, or incorrect data structure.`
            * `Generate a corrected version of the code for the module.`
            * `Return to step 3 (Execute Tests) with the new code.`
            * `If the same test fails more than 5 times, flag it for manual review and proceed to the next module.`
    5.  `**Auto-Complete:** If a test fails due to a missing internal dependency (e.g., a utility function), prioritize implementing that dependency first by recursively invoking this loop on the dependency module.`

---

#### **阶段五：集成、终验与打包 (Finalize & Package)**

**目标：** 确保所有模块协同工作，项目可构建，并生成最终的交付成果。

* **步骤 5.1: 全面集成测试**
    * 指令：`Once all modules are marked 'COMPLETE', run the entire test suite (all unit and integration tests) three times to ensure stability and absence of race conditions.`

* **步骤 5.2: 最终修复**
    * 指令：`If any integration tests fail, analyze the interactions between the involved modules. Apply fixes by modifying the relevant source files and re-run the full test suite until all tests pass.`

* **步骤 5.3: 生成文档和清理**
    * 指令：`Generate a README.md for the /build directory. The README should include a project summary, the detected architecture, and instructions on how to build and run the tests. Remove all temporary test files and artifacts.`

* **步骤 5.4: 最终交付**
    * 指令：`Package the entire /build directory into a zip archive named 'claude-code-source-reconstructed.zip'. The project is now complete.`
