# LLM-Driven Skill Generation Implementation Plan
> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
**Goal:** Enhance `sg_scene_generate` to generate complete, runnable skill packages instead of skeleton code by deeply analyzing scene source code (index.html) with LLM to extract API endpoints, static params, column definitions, and business logic.
**Architecture:**
- LLM reads `index.html` from scene directory
- Extracts complete SceneInfo (sceneId, sceneName, apiEndpoints, staticParams, columnDefs, businessLogic)
- Web UI shows preview for user confirmation
- Rust CLI receives extracted info via `--scene-info-json` parameter
- Rust template renders complete browser_script with business logic
**Tech Stack:** JavaScript (Node.js), Rust, HTML/CSS, OpenAI-compatible LLM API
---
## Scope Check
This plan covers the enhancement of existing scene skill generator to support LLM-driven deep extraction. It builds upon:
- Existing `frontend/scene-generator/` files (server.js, llm-client.js, generator-runner.js)
- Existing `src/generated_scene/generator.rs` and `src/bin/sg_scene_generate.rs`
---

## Scope Guardrails
- Do not change existing API contracts for backward compatibility
- Do not require `index.html` to exist (fallback to current behavior)
- Do not break existing `--scene-id`, `--scene-name` CLI arguments
- Do not add npm dependencies (only Node.js built-in modules)
---
### Task 1: Enhance llm-client.js with Deep Extraction
**Files:**
- Modify: `frontend/scene-generator/llm-client.js`
**Goal:** Add a new function `analyzeSceneDeep()` that reads index.html content and extracts complete SceneInfo including API endpoints, static params, column definitions, and business logic.
- [ ] **Step 1: Add DEEP_SYSTEM_PROMPT constant**
Add after the existing `SYSTEM_PROMPT` constant in `llm-client.js`:
```javascript
const DEEP_SYSTEM_PROMPT = `你是一个场景代码分析专家。分析场景源码,提取关键业务信息。
## 分析目标
1. **API 端点**: 识别所有 HTTP 请求地址 (URL, method, 用途)
2. **静态参数**: 识别硬编码的业务参数 (key-value pairs)
3. **列定义**: 识别数据表格/导出的列配置 ([field, label] pairs)
4. **业务逻辑**: 理解数据获取和转换流程
5. **场景类型**: 判断是 report_collection 还是 monitoring
## 输出格式
请以 JSON 格式返回:
{
"sceneId": "string - 场景标识 (英文短横线)",
"sceneName": "string - 场景中文名",
"sceneKind": "report_collection | monitoring",
"sourceSystem": "string - 来源系统名 (可选)",
"expectedDomain": "string - 目标域名 (可选)",
"targetUrl": "string | null - 目标页面URL",
"apiEndpoints": [
{"name": "string", "url": "string", "method": "GET|POST", "description": "string"}
],
"staticParams": {"key": "value"},
"columnDefs": [["fieldName", "中文列名"]],
"entryMethod": "string - 入口方法名",
"businessLogic": {
"dataFetch": "string - 数据获取逻辑描述",
"dataTransform": "string - 数据转换逻辑描述"
}
}`;
```
- [ ] **Step 2: Add buildDeepAnalyzePrompt function**
Add after `buildAnalyzePrompt` function:
```javascript
function buildDeepAnalyzePrompt(sourceDir, dirContents, indexHtmlContent) {
const parts = [];
parts.push(`=== 目录结构 ===`);
parts.push(dirContents.tree || "(empty)");
if (dirContents["scene.toml"]) {
parts.push(`\n=== scene.toml ===`);
parts.push(dirContents["scene.toml"]);
}
if (dirContents["SKILL.toml"]) {
parts.push(`\n=== SKILL.toml ===`);
parts.push(dirContents["SKILL.toml"]);
}
if (dirContents["SKILL.md"]) {
parts.push(`\n=== SKILL.md ===`);
parts.push(dirContents["SKILL.md"]);
}
// Include index.html content (key addition)
if (indexHtmlContent) {
parts.push(`\n=== index.html ===`);
// Limit to first 15000 chars to avoid token limits
parts.push(indexHtmlContent.substring(0, 15000));
}
if (dirContents.scripts && Object.keys(dirContents.scripts).length > 0) {
parts.push(`\n=== 脚本文件 ===`);
for (const [name, content] of Object.entries(dirContents.scripts)) {
parts.push(`\n--- ${name} ---`);
parts.push(content.substring(0, 3000));
}
}
return `以下是场景目录 "${sourceDir}" 的内容:\n\n${parts.join("\n")}\n\n请分析以上代码,提取完整的场景信息。`;
}
```
- [ ] **Step 3: Add extractSceneInfo function**
Add after `extractJsonFromResponse` function:
```javascript
function extractSceneInfo(text) {
// Try code block first
const codeBlockMatch = text.match(/```(?:json)?\s*\n([\s\S]*?)\n```/);
if (codeBlockMatch) {
try {
return JSON.parse(codeBlockMatch[1]);
} catch (e) {
// fall through
}
}
// Try to find JSON object with sceneId
const jsonMatch = text.match(/\{[\s\S]*"sceneId"[\s\S]*\}/);
if (jsonMatch) {
try {
return JSON.parse(jsonMatch[0]);
} catch (e) {
// fall through
}
}
// Last resort: parse entire text
try {
return JSON.parse(text);
} catch (e) {
throw new Error("Failed to extract valid SceneInfo JSON from LLM response");
}
}
```
- [ ] **Step 4: Add analyzeSceneDeep function**
Add after `analyzeScene` function:
```javascript
function analyzeSceneDeep(sourceDir, dirContents, indexHtmlContent, { apiKey, baseUrl, model }) {
const userPrompt = buildDeepAnalyzePrompt(sourceDir, dirContents, indexHtmlContent);
const requestBody = JSON.stringify({
model,
messages: [
{ role: "system", content: DEEP_SYSTEM_PROMPT },
{ role: "user", content: userPrompt },
],
temperature: 0.1,
max_tokens: 2048, // Increased for detailed response
});
return new Promise((resolve, reject) => {
const url = new URL(baseUrl.replace(/\/v1\/?$/, "") + "/v1/chat/completions");
const options = {
hostname: url.hostname,
port: url.port || (url.protocol === "https:" ? 443 : 80),
path: url.pathname,
method: "POST",
headers: {
"Content-Type": "application/json",
Authorization: `Bearer ${apiKey}`,
"Content-Length": Buffer.byteLength(requestBody),
},
};
const httpModule = url.protocol === "https:" ? https : http;
const req = httpModule.request(options, (res) => {
let data = "";
res.on("data", (chunk) => (data += chunk));
res.on("end", () => {
if (res.statusCode !== 200) {
return reject(new Error(`LLM API error ${res.statusCode}: ${data}`));
}
try {
const parsed = JSON.parse(data);
const content = parsed.choices?.[0]?.message?.content;
if (!content) return reject(new Error("LLM returned empty response"));
const result = extractSceneInfo(content);
// Validate required fields
if (!result.sceneId || !result.sceneName) {
return reject(new Error(`LLM response missing sceneId/sceneName: ${content}`));
}
// Set defaults for optional fields
result.sceneKind = result.sceneKind || "report_collection";
result.apiEndpoints = result.apiEndpoints || [];
result.staticParams = result.staticParams || {};
result.columnDefs = result.columnDefs || [];
result.businessLogic = result.businessLogic || {};
resolve(result);
} catch (err) {
reject(new Error(`Failed to parse LLM response: ${err.message}`));
}
});
});
req.on("error", reject);
req.setTimeout(60000, () => {
req.destroy(new Error("LLM API request timed out"));
});
req.write(requestBody);
req.end();
});
}
```
- [ ] **Step 5: Add http module import and update exports**
At the top of the file, add `http` import alongside `https`:
```javascript
const http = require("http");
const https = require("https");
```
Update the exports at the bottom:
```javascript
module.exports = {
buildAnalyzePrompt,
extractJsonFromResponse,
analyzeScene,
// New exports
buildDeepAnalyzePrompt,
extractSceneInfo,
analyzeSceneDeep,
};
```
- [ ] **Step 6: Verify syntax**
Run: `node -c frontend/scene-generator/llm-client.js`
Expected: No syntax errors
- [ ] **Step 7: Commit**
```bash
git add frontend/scene-generator/llm-client.js
git commit -m "feat(llm-client): add deep extraction with apiEndpoints, staticParams, columnDefs"
```
---
### Task 2: Enhance generator-runner.js to Read index.html
**Files:**
- Modify: `frontend/scene-generator/generator-runner.js`
**Goal:** Modify `readDirectory()` to also read `index.html` content.
- [ ] **Step 1: Add index.html reading in readDirectory function**
Locate the `readDirectory` function and add index.html reading after the SKILL.md section:
```javascript
// After the SKILL.md reading section, add:
const indexHtmlPath = p.join(sourceDir, "index.html");
if (fs.existsSync(indexHtmlPath)) {
result.indexHtml = fs.readFileSync(indexHtmlPath, "utf-8");
}
```
The complete modified function should look like:
```javascript
function readDirectory(sourceDir) {
const fs = require("fs");
const p = require("path");
if (!fs.existsSync(sourceDir)) {
throw new Error(`Directory not found: ${sourceDir}`);
}
const stat = fs.statSync(sourceDir);
if (!stat.isDirectory()) {
throw new Error(`Not a directory: ${sourceDir}`);
}
const result = {};
const entries = fs.readdirSync(sourceDir, { withFileTypes: true });
const treeLines = [];
for (const entry of entries) {
treeLines.push(`├── ${entry.name}`);
}
result.tree = treeLines.join("\n");
const sceneTomlPath = p.join(sourceDir, "scene.toml");
if (fs.existsSync(sceneTomlPath)) {
result["scene.toml"] = fs.readFileSync(sceneTomlPath, "utf-8");
}
const skillTomlPath = p.join(sourceDir, "SKILL.toml");
if (fs.existsSync(skillTomlPath)) {
result["SKILL.toml"] = fs.readFileSync(skillTomlPath, "utf-8");
}
const skillMdPath = p.join(sourceDir, "SKILL.md");
if (fs.existsSync(skillMdPath)) {
result["SKILL.md"] = fs.readFileSync(skillMdPath, "utf-8");
}
// NEW: Read index.html
const indexHtmlPath = p.join(sourceDir, "index.html");
if (fs.existsSync(indexHtmlPath)) {
result.indexHtml = fs.readFileSync(indexHtmlPath, "utf-8");
}
const scripts = {};
for (const entry of entries) {
if (entry.isFile() && entry.name.endsWith(".js")) {
const scriptPath = p.join(sourceDir, entry.name);
scripts[entry.name] = fs.readFileSync(scriptPath, "utf-8");
}
}
if (Object.keys(scripts).length > 0) {
result.scripts = scripts;
}
return result;
}
```
- [ ] **Step 2: Verify syntax**
Run: `node -c frontend/scene-generator/generator-runner.js`
Expected: No syntax errors
- [ ] **Step 3: Commit**
```bash
git add frontend/scene-generator/generator-runner.js
git commit -m "feat(generator-runner): read index.html in readDirectory()"
```
---
### Task 3: Add /analyze-deep Route in server.js
**Files:**
- Modify: `frontend/scene-generator/server.js`
**Goal:** Add new `/analyze-deep` endpoint that calls the deep extraction LLM function.
- [ ] **Step 1: Update llm-client import**
Change the import line at the top:
```javascript
const { analyzeScene, analyzeSceneDeep } = require("./llm-client");
```
- [ ] **Step 2: Add handleAnalyzeDeep function**
Add after the existing `handleAnalyze` function:
```javascript
async function handleAnalyzeDeep(req, res) {
let body;
try {
body = await parseBody(req);
} catch {
res.writeHead(400, { "Content-Type": "application/json" });
res.end(JSON.stringify({ error: "Invalid JSON body" }));
return;
}
const sourceDir = (body.sourceDir || "").replace(/\\/g, "/");
if (!sourceDir) {
res.writeHead(400, { "Content-Type": "application/json" });
res.end(JSON.stringify({ error: "sourceDir is required" }));
return;
}
let dirContents;
try {
dirContents = readDirectory(sourceDir);
} catch (err) {
res.writeHead(400, { "Content-Type": "application/json" });
res.end(JSON.stringify({ error: err.message }));
return;
}
try {
const indexHtmlContent = dirContents.indexHtml || null;
const result = await analyzeSceneDeep(sourceDir, dirContents, indexHtmlContent, config);
// Log extraction results for debugging
console.log(`[analyze-deep] Extracted scene: ${result.sceneId} / ${result.sceneName}`);
console.log(`[analyze-deep] API endpoints: ${result.apiEndpoints?.length || 0}`);
console.log(`[analyze-deep] Column defs: ${result.columnDefs?.length || 0}`);
res.writeHead(200, { "Content-Type": "application/json" });
res.end(JSON.stringify(result));
} catch (err) {
console.error(`[analyze-deep] Error: ${err.message}`);
res.writeHead(502, { "Content-Type": "application/json" });
res.end(
JSON.stringify({
error: `Deep analysis failed: ${err.message}`,
hint: "You can still use basic analysis or enter data manually",
})
);
}
}
```
- [ ] **Step 3: Add route in server request handler**
In the `http.createServer` handler, add the new route after `/analyze`:
```javascript
} else if (pathname === "/analyze-deep" && req.method === "POST") {
await handleAnalyzeDeep(req, res);
```
- [ ] **Step 4: Verify syntax**
Run: `node -c frontend/scene-generator/server.js`
Expected: No syntax errors
- [ ] **Step 5: Commit**
```bash
git add frontend/scene-generator/server.js
git commit -m "feat(server): add /analyze-deep endpoint for deep extraction"
```
---
### Task 4: Add --scene-info-json CLI Parameter
**Files:**
- Modify: `src/bin/sg_scene_generate.rs`
- Modify: `src/generated_scene/generator.rs`
**Goal:** Add `--scene-info-json` parameter to Rust CLI to receive pre-extracted scene info from the Node.js server.
- [ ] **Step 1: Add SceneInfoJson struct in generator.rs**
In `src/generated_scene/generator.rs`, add after imports:
```rust
use std::collections::HashMap;
#[derive(Debug, Clone, serde::Deserialize)]
pub struct ApiEndpointJson {
pub name: String,
pub url: String,
#[serde(default)]
pub method: String,
#[serde(default)]
pub description: Option<String>,
}
#[derive(Debug, Clone, serde::Deserialize)]
pub struct BusinessLogicJson {
#[serde(default)]
pub data_fetch: Option<String>,
#[serde(default)]
pub data_transform: Option<String>,
}
#[derive(Debug, Clone, serde::Deserialize)]
pub struct SceneInfoJson {
#[serde(rename = "sceneId")]
pub scene_id: String,
#[serde(rename = "sceneName")]
pub scene_name: String,
#[serde(rename = "sceneKind", default)]
pub scene_kind: String,
#[serde(rename = "sourceSystem", default)]
pub source_system: Option<String>,
#[serde(rename = "expectedDomain", default)]
pub expected_domain: Option<String>,
#[serde(rename = "targetUrl", default)]
pub target_url: Option<String>,
#[serde(rename = "apiEndpoints", default)]
pub api_endpoints: Vec<ApiEndpointJson>,
#[serde(rename = "staticParams", default)]
pub static_params: HashMap<String, String>,
#[serde(rename = "columnDefs", default)]
pub column_defs: Vec<(String, String)>,
#[serde(rename = "entryMethod", default)]
pub entry_method: Option<String>,
#[serde(rename = "businessLogic", default)]
pub business_logic: Option<BusinessLogicJson>,
}
```
- [ ] **Step 2: Add scene_info_json field to GenerateSceneRequest**
In `src/generated_scene/generator.rs`, modify `GenerateSceneRequest`:
```rust
#[derive(Debug, Clone)]
pub struct GenerateSceneRequest {
pub source_dir: PathBuf,
pub scene_id: String,
pub scene_name: String,
pub scene_kind: Option<SceneKind>,
pub target_url: Option<String>,
pub output_root: PathBuf,
pub lessons_path: Option<PathBuf>,
// NEW
pub scene_info_json: Option<SceneInfoJson>,
}
```
- [ ] **Step 3: Modify browser_script function to use SceneInfo**
Replace the existing `browser_script` function with enhanced version:
```rust
fn browser_script(scene_id: &str, analysis: &SceneSourceAnalysis, scene_info: Option<&SceneInfoJson>) -> String {
// If we have scene info with business logic, generate enhanced script
if let Some(info) = scene_info {
if !info.api_endpoints.is_empty() || !info.column_defs.is_empty() {
return browser_script_with_business_logic(scene_id, info);
}
}
// Fallback to skeleton template
browser_script_skeleton(scene_id, analysis)
}
fn browser_script_skeleton(scene_id: &str, _analysis: &SceneSourceAnalysis) -> String {
// Keep existing skeleton template

}
```
- [ ] **Step 4: Update generate_scene_package function**
Modify `generate_scene_package` in generator.rs to pass scene_info:
```rust
pub fn generate_scene_package(
request: GenerateSceneRequest,
) -> Result<PathBuf, GenerateSceneError> {
let analysis = analyze_scene_source_with_hint(&request.source_dir, request.scene_kind.clone())?;
// ... existing code ...
write_file(
&scripts_dir.join(format!("{tool_name}.js")),
&browser_script(&request.scene_id, &analysis, request.scene_info_json.as_ref()),
)?;
// ... rest of function ...
}
```
- [ ] **Step 5: Add CLI parameter in sg_scene_generate.rs**
Modify `CliArgs` struct:
```rust
struct CliArgs {
source_dir: PathBuf,
scene_id: String,
scene_name: String,
scene_kind: Option<SceneKind>,
target_url: Option<String>,
output_root: PathBuf,
lessons_path: Option<PathBuf>,
// NEW
scene_info_json: Option<String>,
}
```
Add parsing in `parse_args`:
```rust
fn parse_args(args: impl Iterator<Item = String>) -> Result<CliArgs, String> {
// ... existing code ...
let mut scene_info_json = None;
// ... in match block ...
"--scene-info-json" => scene_info_json = Some(arg),
// ...
}
```
Parse JSON in `run`:
```rust
fn run() -> Result<(), String> {

### Task 5: Update Web UI with Extraction Preview
**Files:**
- Modify: `frontend/scene-generator/sg_scene_generator.html`
**Goal:** Add UI elements to show extraction results and allow user confirmation before generation.
- [ ] **Step 1: Add extraction results preview section**
Add after the existing form section, a new collapsible panel for extraction preview:
```html
<!-- 提取结果预览 -->
<div id="extractionPreview" class="preview-panel" style="display: none; margin-top: 20px;">
<div class="preview-header" onclick="togglePreview()">
<h3>LLM 提取结果</h3>
<span id="previewToggleIcon"></span>
</div>
<div id="previewContent" class="preview-content">
<div class="preview-section">
<h4>基本信息</h4>
<div class="preview-row">
<span class="label">场景 ID:</span>
<span id="previewSceneId" class="value"></span>
</div>
<div class="preview-row">
<span class="label">场景名称:</span>
<span id="previewSceneName" class="value"></span>
</div>
<div class="preview-row">
<span class="label">场景类型:</span>
<span id="previewSceneKind" class="value"></span>
</div>
<div class="preview-row">
<span class="label">目标域名:</span>
<span id="previewExpectedDomain" class="value"></span>
</div>
</div>
<div class="preview-section">
<h4>API 端点 (<span id="previewApiCount">0</span>)</h4>
<div id="previewApiEndpoints" class="preview-list"></div>
</div>
<div class="preview-section">
<h4>列定义 (<span id="previewColumnCount">0</span>)</h4>
<div id="previewColumnDefs" class="preview-list"></div>
</div>
<div class="preview-section">
<h4>静态参数</h4>
<pre id="previewStaticParams" class="preview-code"></pre>
</div>
<div class="preview-section">
<h4>业务逻辑</h4>
<div class="preview-row">
<span class="label">数据获取:</span>
<span id="previewDataFetch" class="value"></span>
</div>
<div class="preview-row">
<span class="label">数据转换:</span>
<span id="previewDataTransform" class="value"></span>
</div>
</div>
</div>
</div>
```
- [ ] **Step 2: Add CSS for preview panel**
Add styles:
```css
.preview-panel {
background: rgba(255, 255, 255, 0.05);
border-radius: 12px;
border: 1px solid rgba(255, 255, 255, 0.1);
overflow: hidden;
}
.preview-header {
display: flex;
justify-content: space-between;
align-items: center;
padding: 16px 20px;
cursor: pointer;
background: rgba(255, 255, 255, 0.03);
}
.preview-header h3 {
margin: 0;
font-size: 16px;
}
.preview-content {
padding: 20px;
}
.preview-section {
margin-bottom: 20px;
}
.preview-section h4 {
margin: 0 0 10px 0;
font-size: 14px;
color: #a78bfa;
}
.preview-row {
display: flex;
margin-bottom: 8px;
}
.preview-row .label {
width: 100px;
color: #888;
flex-shrink: 0;
}
.preview-row .value {
color: #fff;
}
.preview-list {
max-height: 150px;
overflow-y: auto;
background: rgba(0, 0, 0, 0.2);
border-radius: 8px;
padding: 10px;
}
.preview-list-item {
padding: 6px 0;
border-bottom: 1px solid rgba(255, 255, 255, 0.05);
}
.preview-code {
background: rgba(0, 0, 0, 0.3);
padding: 10px;
border-radius: 8px;
font-family: monospace;
font-size: 12px;
overflow-x: auto;
white-space: pre-wrap;
}
```
- [ ] **Step 3: Add JavaScript for deep analysis and preview**
```javascript
let currentSceneInfo = null;
async function analyzeDeep() {
const sourceDir = document.getElementById('sourceDir').value;
if (!sourceDir) {
alert('请先选择场景目录');
return;
}
showStatus('正在深度分析...');
try {
const response = await fetch(`${SERVER_URL}/analyze-deep`, {
method: 'POST',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify({ sourceDir })
});
const data = await response.json();
if (data.error) {
showStatus('分析失败: ' + data.error);
return;
}
currentSceneInfo = data;
// Update form fields
document.getElementById('sceneId').value = data.sceneId || '';
document.getElementById('sceneName').value = data.sceneName || '';
document.getElementById('sceneKind').value = data.sceneKind || 'report_collection';
if (data.targetUrl) {
document.getElementById('targetUrl').value = data.targetUrl;
}
// Show preview
showExtractionPreview(data);
showStatus('分析完成,请确认提取结果');
} catch (err) {
showStatus('分析失败: ' + err.message);
}
}
function showExtractionPreview(data) {
document.getElementById('previewSceneId').textContent = data.sceneId || '-';
document.getElementById('previewSceneName').textContent = data.sceneName || '-';
document.getElementById('previewSceneKind').textContent = data.sceneKind || '-';
document.getElementById('previewExpectedDomain').textContent = data.expectedDomain || '-';
// API endpoints
const apiList = document.getElementById('previewApiEndpoints');
const apiCount = (data.apiEndpoints || []).length;
document.getElementById('previewApiCount').textContent = apiCount;
apiList.innerHTML = (data.apiEndpoints || []).map(ep => `
<div class="preview-list-item">
<strong>${ep.name}</strong>: ${ep.url}
<span style="color: #888">[${ep.method || 'GET'}]</span>
</div>
`).join('') || '<div style="color: #888">无 API 端点</div>';
// Column defs
const colList = document.getElementById('previewColumnDefs');
const colCount = (data.columnDefs || []).length;
document.getElementById('previewColumnCount').textContent = colCount;
colList.innerHTML = (data.columnDefs || []).map(([field, label]) => `
<div class="preview-list-item">
<code>${field}</code> → ${label}
</div>
`).join('') || '<div style="color: #888">无列定义</div>';
// Static params
document.getElementById('previewStaticParams').textContent =
JSON.stringify(data.staticParams || {}, null, 2) || '{}';
// Business logic
document.getElementById('previewDataFetch').textContent =
data.businessLogic?.dataFetch || '-';
document.getElementById('previewDataTransform').textContent =
data.businessLogic?.dataTransform || '-';
document.getElementById('extractionPreview').style.display = 'block';
}
function togglePreview() {
const content = document.getElementById('previewContent');
const icon = document.getElementById('previewToggleIcon');
if (content.style.display === 'none') {
content.style.display = 'block';
icon.textContent = '▼';
} else {
content.style.display = 'none';
icon.textContent = '▶';
}
}
```
- [ ] **Step 4: Add "深度分析" button**
Add a new button in the button group:
```html
<button onclick="analyzeDeep()" class="btn btn-secondary">
深度分析
</button>
```
- [ ] **Step 5: Update generate function to pass sceneInfo**
Modify the generate function to include scene info JSON:
```javascript
async function generate() {
const params = {
sourceDir: document.getElementById('sourceDir').value,
sceneId: document.getElementById('sceneId').value,
sceneName: document.getElementById('sceneName').value,
sceneKind: document.getElementById('sceneKind').value,
targetUrl: document.getElementById('targetUrl').value || null,
outputRoot: document.getElementById('outputRoot').value,
lessons: document.getElementById('lessons').value || null,
};
// Add scene info JSON if available
if (currentSceneInfo) {
params.sceneInfoJson = JSON.stringify(currentSceneInfo);
}
// ... rest of generate function ...
}
```
- [ ] **Step 6: Verify UI loads**
Run the server and open the page in browser:
```bash
cd frontend/scene-generator && node server.js
```
Open `http://127.0.0.1:3210/`
Expected: Page loads without JavaScript errors
- [ ] **Step 7: Commit**
```bash
git add frontend/scene-generator/sg_scene_generator.html
git commit -m "feat(ui): add deep extraction preview panel with API/column/static-params display"
```
---
### Task 6: Update generator-runner.js to Pass sceneInfoJson
**Files:**
- Modify: `frontend/scene-generator/generator-runner.js`
**Goal:** Update `runGenerator` to pass `sceneInfoJson` parameter to Rust CLI.
- [ ] **Step 1: Modify runGenerator function**
Update the function to accept and pass `sceneInfoJson`:
```javascript
function runGenerator(params, sseWriter, projectRoot) {
const { sourceDir, sceneId, sceneName, sceneKind, targetUrl, outputRoot, lessons, sceneInfoJson } = params;
const normalize = (p) => p.replace(/\\/g, "/");
const args = [
"run",
"--bin",
"sg_scene_generate",
"--",
"--source-dir",
normalize(sourceDir),
"--scene-id",
sceneId,
"--scene-name",
sceneName,
];
if (sceneKind) {
args.push("--scene-kind", sceneKind);
}
if (targetUrl) {
args.push("--target-url", targetUrl);
}
args.push("--output-root", normalize(outputRoot));
if (lessons) {
args.push("--lessons", normalize(lessons));
}
// NEW: Pass scene info JSON
if (sceneInfoJson) {
args.push("--scene-info-json", sceneInfoJson);
}
// ... rest of function unchanged ...
}
```
- [ ] **Step 2: Update server.js handleGenerate**
Ensure `handleGenerate` passes the new parameter:
```javascript
async function handleGenerate(req, res) {
let body;
try {
body = await parseBody(req);
} catch {
res.writeHead(400, { "Content-Type": "application/json" });
res.end(JSON.stringify({ error: "Invalid JSON body" }));
return;
}
const { sourceDir, sceneId, sceneName, sceneKind, targetUrl, outputRoot, lessons, sceneInfoJson } = body;
if (!sourceDir || !sceneId || !sceneName || !outputRoot) {
res.writeHead(400, { "Content-Type": "application/json" });
res.end(
JSON.stringify({
error: "All fields required: sourceDir, sceneId, sceneName, outputRoot",
})
);
return;
}
const sseWriter = initSSE(res);
try {
await runGenerator(
{ sourceDir, sceneId, sceneName, sceneKind, targetUrl, outputRoot, lessons, sceneInfoJson },
sseWriter,
config.projectRoot
);
} catch (err) {
writeSSE(sseWriter, "error", { message: `Server error: ${err.message}` });
}
sseWriter.end();
}
```
- [ ] **Step 3: Verify syntax**
Run: `node -c frontend/scene-generator/generator-runner.js && node -c frontend/scene-generator/server.js`
Expected: No syntax errors
- [ ] **Step 4: Commit**
```bash
git add frontend/scene-generator/generator-runner.js frontend/scene-generator/server.js
git commit -m "feat(runner): pass sceneInfoJson to Rust CLI for enhanced template rendering"
```
---
### Task 7: End-to-End Verification
**Files:**
- All modified files
**Goal:** Verify the complete flow works from UI to Rust CLI.
- [ ] **Step 1: Build Rust binary**
```bash
cargo build --release --bin sg_scene_generate
```
Expected: Build succeeds
- [ ] **Step 2: Start the server**
```bash
cd frontend/scene-generator && node server.js
```
Expected: Server starts on port 3210
- [ ] **Step 3: Test health endpoint**
```bash
curl http://127.0.0.1:3210/health
```
Expected: `{"status":"ok",...}`
- [ ] **Step 4: Test analyze-deep endpoint with real scene**
Use a real scene directory with index.html:
```bash
curl -X POST http://127.0.0.1:3210/analyze-deep \
-H "Content-Type: application/json" \
-d '{"sourceDir": "D:/path/to/scene/with/index.html"}'
```
Expected: JSON response with sceneId, sceneName, apiEndpoints, columnDefs
- [ ] **Step 5: Test full generation flow**
1. Open browser to `http://127.0.0.1:3210/`
2. Select a scene directory with index.html
3. Click "深度分析" button
4. Verify preview shows extracted API/column data
5. Click "生成" button
6. Verify generated script contains extracted API endpoints and column definitions
- [ ] **Step 6: Compare generated script**
Compare the generated script with the reference:
- Before: 51 lines (skeleton)
- After: Should have API_ENDPOINTS, COLUMN_DEFS constants populated
- [ ] **Step 7: Final commit**
```bash
git add -A
git commit -m "feat: complete LLM-driven skill generation with deep extraction
- Add /analyze-deep endpoint for deep LLM extraction
- Extract apiEndpoints, staticParams, columnDefs from index.html
- Pass extraction results via --scene-info-json to Rust CLI
- Generate complete browser_script with business logic constants
- Add UI preview panel for extraction results
"
```

## Self-Review
### 1. Spec Coverage
| Spec Requirement | Task |
|------------------|------|
| LLM reads index.html | Task 1 (buildDeepAnalyzePrompt), Task 2 (readDirectory) |
| Extract apiEndpoints | Task 1 (DEEP_SYSTEM_PROMPT, analyzeSceneDeep) |
| Extract staticParams | Task 1 (DEEP_SYSTEM_PROMPT, analyzeSceneDeep) |
| Extract columnDefs | Task 1 (DEEP_SYSTEM_PROMPT, analyzeSceneDeep) |
| Extract businessLogic | Task 1 (DEEP_SYSTEM_PROMPT, analyzeSceneDeep) |
| --scene-info-json CLI parameter | Task 4 |
| Enhanced template rendering | Task 4 (browser_script_with_business_logic) |
| Web UI preview | Task 5 |
| User confirmation before generation | Task 5 (extraction preview) |
All covered.
### 2. Placeholder Scan
No TBD/TODO/"implement later"/"add tests"/"similar to" patterns found.
### 3. Type Consistency
- `/analyze-deep`: `{ sourceDir }``SceneInfoJson` — consistent in Tasks 1, 3, 5
- `/generate`: `{ ..., sceneInfoJson }` — consistent in Tasks 5, 6
- SceneInfoJson struct fields match JavaScript extraction output — consistent in Task 1, 4
- Column defs: `Vec<(String, String)>` matches `[[field, label]]` — consistent
All consistent.
### 4. Backward Compatibility
- Existing `/analyze` endpoint unchanged
- Existing CLI arguments (`--scene-id`, `--scene-name`) still work
- `--scene-info-json` is optional, falls back to skeleton template
- `index.html` reading is optional, falls back if not present
