-## Skill File Format
-
-Each skill follows this structure:

----
-
-# Skill Title
-
-## Quick Start / Quick Reference
-## Main Content Sections
-## Troubleshooting
-## Reference Files
-```
-
-### YAML Frontmatter
-
-Required fields:
-- `name`: kebab-case identifier matching directory name
-- `description`: Detailed description for AI agent matching (trigger keywords)
-
-## Documentation Conventions
-
-- Use tables for command references and parameters
-- Include code blocks with language specifiers (`typescript`, `bash`)
-- Cross-reference related skills and reference files
-- Use bilingual content (Chinese/English) for HarmonyOS context
-- Structure: Quick Reference first, then detailed sections
-
-## File Organization
-
-- Main skill definition: `SKILL.md` (uppercase)
-- Code templates: `assets/*.ets`
-- Reference documentation: `references/*.md`
-- All filenames: kebab-case
-
-## Common Patterns
-
-### State Management Decorators
-
-| Decorator | Direction | Usage |
-|-----------|-----------|-------|
-| `@State` | Internal | Component's own mutable state |
-| `@Prop` | Parent → Child | One-way binding (child copy) |
-| `@Link` | Parent ↔ Child | Two-way binding (pass with `$var`) |
-| `@Provide/@Consume` | Ancestor → Descendant | Cross-level state sharing |
-
-### Layout Components
-
-```typescript
-Column({ space: 10 }) { }  // Vertical layout
-Row({ space: 10 }) { }     // Horizontal layout
-Stack() { }                 // Overlay layout
-List({ space: 10 }) { }    // Scrollable list
-```
-
-### ForEach Pattern
-
-Always provide explicit types and key generator:
+### ForEach -- always provide types and a key generator
 
 ```typescript
 ForEach(this.items, (item: ItemType) => {
   ListItem() { Text(item.title) }
-}, (item: ItemType) => item.id)  // Key generator for efficient updates
+}, (item: ItemType) => item.id)
 ```
+
+## Skill File Format
+
+Every skill directory contains a `SKILL.md` with YAML frontmatter:
+
+```markdown
+---
+name: skill-name          # kebab-case, matches directory name
+description: ...          # Detailed description for agent matching
+---
+# Skill Title
+## Quick Start / Quick Reference
+## Detailed Sections
+## Troubleshooting
+## Reference Files
+```
+
+### File Organization Rules
+
+- Main definition: `SKILL.md` (uppercase)
+- Code templates: `assets/*.ets`
+- Reference docs: `references/*.md`
+- All filenames: **kebab-case**
+
+## Documentation Conventions
+
+- Use **tables** for command references and parameter lists.
+- Use **fenced code blocks** with language specifiers (`typescript`, `bash`).
+- Structure content as: Quick Reference first, then detailed sections.
+- Cross-reference related skills and reference files by relative path.

+## Quick Deploy
+
+Use [skills.sh](https://skills.sh/) to deploy skills to your project with a single command.
+
+### Install all skills
+
+```bash
+npx skills add FadingLight9291117/arkts_skills
+```
+
+### Install a single skill
+
+You can install a specific skill from this repo using the `--skill` flag:
+
+```bash
+npx skills add https://github.com/FadingLight9291117/arkts_skills --skill harmonyos-build-deploy
+npx skills add https://github.com/FadingLight9291117/arkts_skills --skill arkts-development
+```
+
+Or search for skills on [skills.sh](https://skills.sh/) and run the corresponding install command:
+
+```bash
+npx skills add <owner/repo>
+```
+
+Once installed, the skill is automatically configured for your AI agent (supports Cursor, Claude Code, Copilot, and other major agents).
+
+> No additional CLI installation required — `npx` downloads and runs it automatically. To disable anonymous telemetry, set the environment variable `DISABLE_TELEMETRY=1`.

+# ArkGuard Code Obfuscation Guide
+
+ArkGuard is the officially recommended code obfuscation tool for HarmonyOS, designed to enhance application security and prevent reverse engineering.
+
+## Requirements
+
+- **DevEco Studio**: Version 5.0.3.600 or above
+- **Project Model**: Stage model only
+- **Effective Mode**: Only active in Release mode
+
+## Enabling Obfuscation
+
+Configure in the module's `build-profile.json5`:
+
+```json
+{
+  "arkOptions": {
+    "obfuscation": {
+      "ruleOptions": {
+        "enable": true,
+        "files": ["./obfuscation-rules.txt"]
+      },
+      "consumerFiles": ["./consumer-rules.txt"]
+    }
+  }
+}
+```
+
+## Obfuscation Rules Configuration
+
+Create `obfuscation-rules.txt` in the project root directory:
+
+```text
+# Enable property obfuscation
+-enable-property-obfuscation
+
+# Enable top-level scope name obfuscation
+-enable-toplevel-obfuscation
+
+# Enable filename obfuscation
+-enable-filename-obfuscation
+
+# Enable import/export name obfuscation
+-enable-export-obfuscation
+```
+
+## Whitelist Configuration
+
+Certain names must not be obfuscated (e.g., dynamic property names, API fields, database fields):
+
+```text
+# Keep property names
+-keep-property-name apiKey
+-keep-property-name userId
+-keep-property-name responseData
+
+# Keep global names
+-keep-global-name AppConfig
+
+# Keep file names
+-keep-file-name MainPage
+-keep-file-name LoginPage
+```
+
+## Configuration Files
+
+| Config File | Purpose | Editable | Scope |
+|-------------|---------|:--------:|-------|
+| `obfuscation-rules.txt` | Obfuscation rules applied when building this module | ✓ | Current module |
+| `consumer-rules.txt` | Obfuscation rules applied when this module is used as a dependency (recommended: keep rules only) | ✓ | Modules depending on this module |
+| `obfuscation.txt` | HAR/HSP build artifact, auto-generated | ✗ | Dependent modules |
+
+## Common Obfuscation Options
+
+| Option | Description |
+|--------|-------------|
+| `-enable-property-obfuscation` | Obfuscate object property names |
+| `-enable-toplevel-obfuscation` | Obfuscate top-level scope variable and function names |
+| `-enable-filename-obfuscation` | Obfuscate file names |
+| `-enable-export-obfuscation` | Obfuscate import/export names |
+| `-disable-obfuscation` | Temporarily disable obfuscation (for debugging) |
+
+## Whitelist Options
+
+| Option | Description |
+|--------|-------------|
+| `-keep-property-name <name>` | Preserve specified property name from obfuscation |
+| `-keep-global-name <name>` | Preserve specified global name from obfuscation |
+| `-keep-file-name <name>` | Preserve specified file name from obfuscation |
+
+## Troubleshooting
+
+### Diagnostic Steps
+
+1. **Confirm obfuscation is the cause**: Temporarily add `-disable-obfuscation` and check if the issue disappears
+2. **Locate the problematic field**: Identify the obfuscated field from crash logs
+3. **Add to whitelist**: Add the problematic field to the `-keep-property-name` whitelist
+
+### Common Scenarios Requiring Whitelisting
+
+- **Network requests**: Request parameter field names, response data field names
+- **Database operations**: Table field names
+- **System APIs**: System callback parameters
+- **Third-party library interfaces**: Field names required by third-party libraries
+
+### Example: Preserving Network Request Fields
+
+```text
+# API request/response fields
+-keep-property-name code
+-keep-property-name message
+-keep-property-name data
+-keep-property-name token
+-keep-property-name userId
+```
+
+## Verifying Obfuscation Results
+
+1. Switch to **Release** mode and build
+2. Inspect the build artifacts
+3. Use decompilation tools to verify that class/method/property names are obfuscated
+4. Test that the application functions correctly

+## Output
 
-- 解析结果输出到 `-o` 指定目录，文件以原始 crash 文件名加 `_` 前缀命名
-- 不指定 `-o` 时：
-  - 使用 `-i` 输入：输出到 crashDir 目录
-  - 使用 `-c` 输入：直接输出到控制台
+- Parsed results are written to the directory specified by `-o`, with filenames prefixed by `_` followed by the original crash filename
+- When `-o` is not specified:
+  - With `-i` input: output to the crashDir directory
+  - With `-c` input: output directly to console

-### 解析步骤
+### Resolution Steps
 
-1. **根据路径信息找到 sourcemap**
-   - 从路径 `entry|har|1.0.0|src/main/ets/...` 在 entry 模块 sourcemap 中查找对应字段
+1. **Find the sourcemap based on path information**
+   - From the path `entry|har|1.0.0|src/main/ets/...`, look up the corresponding field in the entry module's sourcemap
 
-2. **利用 sourcemap 还原路径和行列号**
-   - 根据 `sources` 和 `mappings` 字段解析
-   - 如包含 `package-info`，可进行二次解析获取更准确的源码位置
+2. **Restore path and line/column numbers using sourcemap**
+   - Parse using the `sources` and `mappings` fields
+   - If `package-info` is included, perform a secondary parse for more accurate source locations
 
-3. **利用 nameCache 还原方法名**
-   - 查找混淆后方法名对应的所有条目
-   - 根据还原后的行号范围匹配正确的源码方法名
+3. **Restore method names using nameCache**
+   - Find all entries matching the obfuscated method name
+   - Match the correct source method name based on the restored line number range
