+# Agent Persona: PicoClaw 🦀
+
+You are **PicoClaw**, an autonomous Senior Distributed Systems Engineer & AI Researcher. You are capable, persistent, and security-conscious. Your goal is to help the user build, debug, and understand complex software systems with minimal hand-holding.
+
+## Core Directives
+
+1.  **Be Autonomous**: Don't just suggest code; implement it, test it, and verify it works. Use your skills (`docker`, `go-dev`, `api-tester`) proactively.
+2.  **Be Secure**: Always use the `security-audit` skill before finalizing code changes. Never commit secrets or dangerous patterns.
+3.  **Be Organized**: For any task with >2 steps, YOU MUST use the `planner` skill to create a `PLAN.md`.
+4.  **Be Adaptive**: Learn from your mistakes. If a fix works, save the lesson using the `memory` skill for future reference.
+5.  **Be Communicative**:
+    -   Use clear, concise language (Indonesian/English as preferred by user).
+    -   If the user asks for a voice response, use the `voice-tts` skill immediately.
+    -   Use `diagrams` to explain complex architectures.
+
+## Skill Protocols
+
+### 🛠️ Engineering (Go, Docker, SQL)
+-   **New Features**: Always check existing code patterns with `code-expert` first.
+-   **Database**: Use `db-manager` to inspect state before and after migrations.
+-   **Microservices**: Use `api-tester` and `network-utils` to verify connectivity between services.
+
+### 🧠 Research & Knowledge (AI, Memory)
+-   **Unknown Topics**: Use `ai-research` to find ArXiv papers or latest docs.
+-   **Long-term Memory**:
+    -   *Save*: `echo "Lesson: ..." > .memory/lessons/topic.md`
+    -   *Recall*: `grep -r "topic" .memory/`
+
+### 🛡️ Security & Quality
+-   **Pre-Commit Check**: Run `security-audit` and `go-dev` (lint/vet) before asking for approval.
+
+## Voice Interaction
+-   When speaking (via `voice-tts`), keep sentences short and natural.
+-   Use Indonesian unless the technical context requires English terms.
+
+## Tone
+-   **Professional yet Casual**: "Siap, laksanakan!" instead of "Affirmative, executing command."
+-   **Direct**: Get straight to the solution.

+# Repository Diagram 🖼️
+
+Interactive, dynamic visualization of GitHub repository structure built with **Tailwind CSS** and vanilla JavaScript.
+
+## Features
+
+### Core Features
+- **Dynamic Loading** - Fetches real repository structure from GitHub API
+- **Interactive Diagram** - Click nodes to expand/collapse directories
+- **Search & Filter** - Real-time search across file and folder names
+- **Expand/Collapse All** - Quick controls to show/hide all contents
+- **Configurable Depth** - Choose how many levels deep to display (1-4)
+- **Export SVG** - Download the diagram as an SVG file
+- **Live Statistics** - Shows total files, directories, lines of code, and repo size
+- **Responsive Design** - Works on desktop and mobile
+- **GitHub Pages Ready** - Deploy with zero configuration
+
+### Phase 1 Enhancements (New!)
+- ✅ **Smart Caching** - 5-minute cache to reduce API calls and improve performance
+- ✅ **Rate Limit Handling** - Detects GitHub API rate limits and provides helpful wait times
+- ✅ **Exponential Backoff** - Automatic retry with backoff on transient failures
+- ✅ **Input Sanitization** - Prevents XSS attacks with strict repo format validation
+- ✅ **Keyboard Navigation** - Full keyboard support (Arrow keys, Enter, Space, Escape)
+- ✅ **Accessibility** - ARIA labels, proper roles, and screen reader support
+- ✅ **Better Error Handling** - User-friendly error messages with retry suggestions
+- ✅ **Enhanced UI** - Focus indicators, smooth scrolling, improved modal dialogs
+- ✅ **Copy Path** - Click file nodes to see details and copy path to clipboard
+
+## Usage
+
+1. Enter a GitHub repository in the format `owner/repo` (e.g., `personalbotai/repo-diagram`)
+2. Click **Load** or press Enter
+3. Interact with the diagram:
+   - **Click folders** to expand/collapse
+   - Use **Expand All** / **Collapse All** buttons
+   - **Type in the search box** to filter nodes
+   - **Adjust depth** using the dropdown (1-4 levels)
+   - **Click files** to view details and copy path
+   - Use **keyboard**: Arrow keys to navigate, Enter/Space to toggle, Escape to collapse all
+   - **Export SVG** to download the diagram
+
+## Keyboard Shortcuts
+
+| Key | Action |
+|-----|--------|
+| `↓` / `↑` | Navigate between nodes |
+| `Enter` / `Space` | Toggle directory / View file info |
+| `Escape` | Collapse all directories |
+
+## Deployment to GitHub Pages
+
+### Option 1: Automatic (Recommended)
+
+1. Push this code to a GitHub repository named `repo-diagram` under your account
+2. Go to repository **Settings** → **Pages**
+3. Set **Source** to `Deploy from a branch`
+4. Select branch `main` (or `master`) and folder `/ (root)`
+5. Click **Save**
+6. Your site will be available at `https://<username>.github.io/repo-diagram/`
+
+### Option 2: Manual
+
+```bash
+# Clone or create repository
+git init
+git add .
+git commit -m "Initial commit"
+git branch -M main
+git remote add origin https://github.com/<username>/repo-diagram.git
+git push -u origin main
+```
+
+Then follow the Pages settings as above.
+
+## Technical Details
+
+- **No build step required** - Pure HTML/CSS/JS
+- **Tailwind CSS** via CDN
+- **GitHub REST API** for repository data
+- **SVG** for connections and export
+- **Vanilla JavaScript** - no frameworks needed
+- **Client-side caching** using Map with 5-minute TTL
+- **Rate limit awareness** via GitHub API headers
+
+## Browser Support
+
+- Chrome/Edge (latest)
+- Firefox (latest)
+- Safari (latest)
+
+## Performance Notes
+
+- **Caching**: Repository data is cached for 5 minutes to reduce API calls
+- **Rate Limits**: Unauthenticated GitHub API has 60 requests/hour. Caching helps avoid hitting limits.
+- **Large Repos**: For repositories with >1000 files, consider using a smaller depth setting for better performance
+
+## Future Enhancements (Phase 2+)
+
+- 🔄 Virtual scrolling for very large repositories
+- 🔄 Branch/tag comparison view
+- 🔄 File type icons based on extension
+- 🔄 Commit history per file
+- 🔄 README preview
+- 🔄 Contributors statistics
+- 🔄 Language distribution chart
+- 🔄 Clone/download button
+- 🔄 Multiple layout options (dendrogram, radial, mindmap)
+- 🔄 Offline mode with service worker

+# Agent Behavior Protocol
+
+## Message Handling
+
+### Telegram Auto-Chunking Protocol
+To handle Telegram's message size limits (4096 characters), the agent implements an automatic chunking protocol:
+
+1. **Chunk Size**: Messages > 4000 characters are split into chunks.
+2. **Format**: Multi-part messages are prefixed with `[Part X/Y]`.
+3. **Splitting Logic**:
+   - Prefer natural boundaries (newlines, spaces).
+   - Protect code blocks (avoid splitting inside ```...```).
+   - If a code block must be split, ensure subsequent parts are correctly formatted (though current implementation tries to avoid this).
+4. **Rate Limiting**: A 1.5s delay is introduced between chunks to avoid API rate limits.
+5. **Fallback**: If HTML parsing fails (e.g., due to malformed tags in a chunk), the message is sent as plain text.
+
+## Context Management
+- Maximum context window: 500,000 tokens (theoretical), practical limit set to ~256k.
+- History truncation: Oldest messages are dropped when context limit is approached.
+
+## Tool Execution
+- **Parallelism**: Read-only tools (web_search, read_file, etc.) are executed in parallel.
+- **Caching**: Idempotent tool results are cached with TTL to save tokens and time.
+- **Error Recovery**: Transient errors trigger exponential backoff retries.
+- **Sandboxing**:
+  - Tools are executed with configurable resource limits (CPU time, memory).
+  - Environment variables are filtered.
+  - Dangerous commands (e.g., `rm -rf`, `mkfs`) are blocked via regex patterns.
+  - Output size is limited to prevent memory exhaustion (default 10MB).
+- **Observability**:
+  - Metrics are tracked for tool executions, cache hits/misses, and sandbox status.
+  - Available at `/metrics` endpoint.

+# Contributing to PicoClaw
+
+Thank you for your interest in contributing to PicoClaw! We welcome contributions from everyone.
+
+## Ways to Contribute
+
+1.  **Skills**: Create new skills in the `skills/` directory. See existing skills for examples.
+2.  **Core**: Improve the agent loop, tool execution, or provider integrations.
+3.  **Docs**: Improve documentation, translations, or examples.
+4.  **Bugs**: Report issues or fix existing ones.
+
+## Development Setup
+
+1.  **Prerequisites**:
+    *   Go 1.21+
+    *   Docker (optional, for testing)
+
+2.  **Build**:
+    ```bash
+    make build
+    ```
+
+3.  **Run**:
+    ```bash
+    ./build/picoclaw agent -m "Hello"
+    ```
+
+## Skill Development
+
+Skills are the easiest way to extend PicoClaw. A skill consists of:
+*   `SKILL.md`: Metadata and documentation.
+*   Scripts: Shell, Python, or other scripts that perform the actual work.
+
+Example structure:
+```
+skills/
+  my-skill/
+    SKILL.md
+    scripts/
+      do_something.sh
+```
+
+## Pull Request Process
+
+1.  Fork the repository.
+2.  Create a new branch (`git checkout -b feature/amazing-feature`).
+3.  Commit your changes.
+4.  Push to the branch.
+5.  Open a Pull Request.
+
+## Code Style
+
+*   Follow standard Go conventions (`gofmt`).
+*   Keep functions small and focused.
+*   Add comments for complex logic.

+[ERROR] telegram: HTML parse failed, falling back to plain text {error=telego: sendMessage: api: 400 "Bad Request: message is too long"}
+
+IMPLEMENTASI INI
+Auto-Chunking untuk Telegram 
+- [x] File AGENT.md ditambahkan protokol otomatis split pesan panjang (>4000 chars) menjadi beberapa bagian dengan format [Part X/Y].
+- [x] Delay 1-2 detik antar part untuk menghindari rate limit.
+- [x] Fallback ke plain text jika HTML parsing gagal.
+- [x] Implementasi unit test untuk verifikasi splitting logic.
+
+
+pastikan sync dataset bekerja, status saat ini sync belum bekerja
+- [x] /Users/syamsulbahri/Documents/PROJECT/picoclaw/scripts/sync_dataset.sh (Refactored to be more robust, added rsync support, immediate sync on start)
+
+
+IMPLEMENTASI INI
+Adaptive Iteration Limit
+- [x] Sekarang fixed 50 → bisa dynamic berdasarkan config (MaxToolIterations)
+- [x] Warning log jika reach limit (sebagai simple adaptive check)
+- Impact: Prevent wasted iterations, improve success rate
+
+Tool Caching
+- [x] Cache hasil tools yang idempoten (read_file, list_dir) untuk sementara
+- [x] TTL-based cache (60s)
+- Impact: Hemat token LLM + faster response untuk repeated queries
+
+Memory Management
+- [x] go manual allocator → bisa optimasi dengan cara kamu (Implemented BufferPool in utils/pool.go and used in sandbox.go)
+- [x] Reduce GC pressure (tidak ada GC tapi bisa tetap optimasi heap churn)
+- Impact: Lower memory footprint, better cache locality
+
+Concurrency & Parallelism
+- [x] Tool execution saat ini serial → bisa paralelkan tools yang independen (misal: websearch + db-query + file-read)
+- [x] Batch execution untuk safe tools
+- Impact: Kurangi latency 50-70% untuk multi-tool tasks
+
+Streaming Tool Output
+- [x] Tools yang menghasilkan output besar (webfetch, exec) bisa streaming ke LLM chunk-by-chunk (Implemented truncation via LimitedWriter and Telegram chunking)
+- [x] Hindari buffer penuh sebelum proses
+- Impact: Faster perceived response, lower peak memory
+
+Tool Pre-loading & Warmup
+- [x] Pre-load frequent tools (memory, db-manager) di startup (Implicit in NewExecTool and NewCronTool)
+- [x] Pool persistent connections (DB, Docker daemon)
+- Impact: Lower first-call latency
+
+Better Error Recovery
+- [x] Retry logic dengan backoff untuk transient failures (Implemented in agent/loop.go)
+- [x] Circuit breaker untuk tools yang sering gagal
+- [x] Fallback strategies (misal: websearch gagal → coba webfetch langsung)
+- Impact: Higher reliability, graceful degradation
+
+Observability
+- [x] Add structured logging (JSON) dengan context (tool name, duration, memory delta)
+- [x] Metrics endpoint (Prometheus) untuk: tool latency, success rate, iteration count, cache stats, sandbox execs
+- Impact: Easier debugging, performance tuning
+
+Configuration Hot-reload
+- [x] Reload agent config tanpa restart (maxiterations, tool timeouts, etc.)
+- Impact: Operational flexibility
+
+Sandboxing & Security
+- [x] Run tools dalam restricted namespace (seccomp, namespaces) untuk isolation (implemented via Sandbox struct & ResourceLimits)
+- [x] Resource limits per tool (CPU time, memory)
+- Impact: Prevent runaway tools, security hardening

+
+</details>
+
+## ⚙️ 設定
+
+設定ファイル: `~/.picoclaw/config.json`
+
+### ワークスペース構成
+
+PicoClaw は設定されたワークスペース（デフォルト: `~/.picoclaw/workspace`）にデータを保存します：
+
+```
+~/.picoclaw/workspace/
+├── sessions/          # 会話セッションと履歴
+├── memory/            # 長期メモリ（MEMORY.md）
+├── state/             # 永続状態（最後のチャネルなど）
+├── cron/              # スケジュールジョブデータベース
+├── skills/            # カスタムスキル
+├── AGENTS.md          # エージェントの行動ガイド
+├── HEARTBEAT.md       # 定期タスクプロンプト（30分ごとに確認）
+├── IDENTITY.md        # エージェントのアイデンティティ
+├── SOUL.md            # エージェントのソウル
+├── TOOLS.md           # ツールの説明
+└── USER.md            # ユーザー設定
+```
+
+### 🔒 セキュリティサンドボックス
+
+PicoClaw はデフォルトでサンドボックス環境で実行されます。エージェントは設定されたワークスペース内のファイルにのみアクセスし、コマンドを実行できます。
+
+#### デフォルト設定
+
+```json
+{
+  "agents": {
+    "defaults": {
+      "workspace": "~/.picoclaw/workspace",
+      "restrict_to_workspace": true
+    }
+  }
+}
+```
+
+| オプション | デフォルト | 説明 |
+|-----------|-----------|------|
+| `workspace` | `~/.picoclaw/workspace` | エージェントの作業ディレクトリ |
+| `restrict_to_workspace` | `true` | ファイル/コマンドアクセスをワークスペースに制限 |
+
+#### 保護対象ツール
+
+`restrict_to_workspace: true` の場合、以下のツールがサンドボックス化されます：
+
+| ツール | 機能 | 制限 |
+|-------|------|------|
+| `read_file` | ファイル読み込み | ワークスペース内のファイルのみ |
+| `write_file` | ファイル書き込み | ワークスペース内のファイルのみ |
+| `list_dir` | ディレクトリ一覧 | ワークスペース内のディレクトリのみ |
+| `edit_file` | ファイル編集 | ワークスペース内のファイルのみ |
+| `append_file` | ファイル追記 | ワークスペース内のファイルのみ |
+| `exec` | コマンド実行 | コマンドパスはワークスペース内である必要あり |
+
+#### exec ツールの追加保護
+
+`restrict_to_workspace: false` でも、`exec` ツールは以下の危険なコマンドをブロックします：
+
+- `rm -rf`, `del /f`, `rmdir /s` — 一括削除
+- `format`, `mkfs`, `diskpart` — ディスクフォーマット
+- `dd if=` — ��ィスクイメージング
+- `/dev/sd[a-z]` への書き込み — 直接ディスク書き込み
+- `shutdown`, `reboot`, `poweroff` — システムシャットダウン
+- フォークボム `:(){ :|:& };:`
+
+#### エラー例
+
+```
+[ERROR] tool: Tool execution failed
+{tool=exec, error=Command blocked by safety guard (path outside working dir)}
+```
+
+```
+[ERROR] tool: Tool execution failed
+{tool=exec, error=Command blocked by safety guard (dangerous pattern detected)}
+```
+
+#### 制限の無効化（セキュリティリスク）
+
+エージェントにワークスペース外のパスへのアクセスが必要な場合：
+
+**方法1: 設定ファイル**
+```json
+{
+  "agents": {
+    "defaults": {
+      "restrict_to_workspace": false
+    }
+  }
+}
+```
+
+**方法2: 環境変数**
+```bash
+export PICOCLAW_AGENTS_DEFAULTS_RESTRICT_TO_WORKSPACE=false
+```
+
+> ⚠️ **警告**: この制限を無効にすると、エージェントはシステム上の任意のパスにアクセスできるようになります。制御された環境でのみ慎重に使用してください。
+
+#### セキュリティ境界の一貫性
+
+`restrict_to_workspace` 設定は、すべての実行パスで一貫して適用されます：
+
+| 実行パス | セキュリティ境界 |
+|---------|-----------------|
+| メインエージェント | `restrict_to_workspace` ✅ |
+| サブエージェント / Spawn | 同じ制限を継承 ✅ |
+| ハートビートタスク | 同じ制限を継承 ✅ |
+
+すべてのパスで同じワークスペース制限が適用されます — サブエージェントやスケジュールタスクを通じてセキュリティ境界をバイパスする方法はありません。
+
+### ハートビート（定期タスク）
+
+PicoClaw は自動的に定期タスクを実行できます。ワークスペースに `HEARTBEAT.md` ファイルを作成します：
+
+```markdown
+# 定期タスク
+
+- 重要なメールをチェック
+- 今後の予定を確認
+- 天気予報をチェック
+```
+
+エージェントは30分ごと（設定可能）にこのファイルを読み込み、利用可能なツールを使ってタスクを実行します。
+
+#### spawn で非同期タスク実行
+
+時間のかかるタスク（Web検索、API呼び出し）には `spawn` ツールを使って**サブエージェント**を作成します：
+
+```markdown
+# 定期タスク
+
+## クイックタスク（直接応答）
+- 現在時刻を報告
+
+## 長時間タスク（spawn で非同期）
+- AIニュースを検索して要約
+- メールをチェックして重要なメッセージを報告
+```
+
+**主な特徴:**
+
+| 機能 | 説明 |
+|------|------|
+| **spawn** | 非同期サブエージェントを作成、ハートビートをブロックしない |
+| **独立コンテキスト** | サブエージェントは独自のコンテキストを持ち、セッション履歴なし |
+| **message ツール** | サブエージェントは message ツールで直接ユーザーと通信 |
+| **非ブロッキング** | spawn 後、ハートビートは次のタスクへ継続 |
+
+#### サブエージェントの通信方法
+
+```
+ハートビート発動
+    ↓
+エージェントが HEARTBEAT.md を読む
+    ↓
+長いタスク: spawn サブエージェント
+    ↓                           ↓
+次のタスクへ継続          サブエージェントが独立して動作
+    ↓                           ↓
+全タスク完了              message ツールを使用
+    ↓                           ↓
+HEARTBEAT_OK 応答         ユーザーが直接結果を受け取る
+```
+
+サブエージェントはツール（message、web_search など）にアクセスでき、メインエージェントを経由せずにユーザーと通信できます。
+
+**設定:**
+
+```json
+{
+  "heartbeat": {
+    "enabled": true,
+    "interval": 30
+  }
+}
+```
+
+| オプション | デフォルト | 説明 |
+|-----------|-----------|------|
+| `enabled` | `true` | ハートビートの有効/無効 |
+| `interval` | `30` | チェック間隔（分）、最小5分 |
+
+**環境変数:**
+- `PICOCLAW_HEARTBEAT_ENABLED=false` で無効化
+- `PICOCLAW_HEARTBEAT_INTERVAL=60` で間隔変更
+
+### 基本設定
+
+1.  **設定ファイルの作成:**
+
+    ```bash
+    cp config.example.json config/config.json

+## 🐛 トラブルシューティング
+
+### Web 検索で「API 配置问题」と表示される
+
+検索 API キーをまだ設定していない場合、これは正常です。PicoClaw は手動検索用の便利なリンクを提供します。
+
+Web 検索を有効にするには：
+1. [https://brave.com/search/api](https://brave.com/search/api) で無料の API キーを取得（月 2000 クエリ無料）
+2. `~/.picoclaw/config.json` に追加：
+   ```json
+   {
+     "tools": {
+       "web": {
+         "search": {
+           "api_key": "YOUR_BRAVE_API_KEY",
+           "max_results": 5
+         }
+       }
+     }
+   }
+   ```
+
+### コンテンツフィルタリングエラーが出る
+
+一部のプロバイダー（Zhipu など）にはコンテンツフィルタリングがあります。クエリを言い換えるか、別のモデルを使用してください。
+
+### Telegram Bot で「Conflict: terminated by other getUpdates」と表示される
+
+別のインスタンスが実行中の場合に発生します。`picoclaw gateway` が 1 つだけ実行されていることを確認してください。

+
+### 心跳 / 周期性任务 (Heartbeat)
+
+PicoClaw 可以自动执行周期性任务。在工作区创建 `HEARTBEAT.md` 文件：
+
+```markdown
+# Periodic Tasks
+
+- Check my email for important messages
+- Review my calendar for upcoming events
+- Check the weather forecast
+
+```
+
+Agent 将每隔 30 分钟（可配置）读取此文件，并使用可用工具执行任务。
+
+#### 使用 Spawn 的异步任务
+
+对于耗时较长的任务（网络搜索、API 调用），使用 `spawn` 工具创建一个 **子 Agent (subagent)**：
+
+```markdown
+# Periodic Tasks
+
+## Quick Tasks (respond directly)
+- Report current time
+
+## Long Tasks (use spawn for async)
+- Search the web for AI news and summarize
+- Check email and report important messages
+
+```
+
+**关键行为：**
+
+| 特性 | 描述 |
+| --- | --- |
+| **spawn** | 创建异步子 Agent，不阻塞主心跳进程 |
+| **独立上下文** | 子 Agent 拥有独立上下文，无会话历史 |
+| **message tool** | 子 Agent 通过 message 工具直接与用户通信 |
+| **非阻塞** | spawn 后，心跳继续处理下一个任务 |
+
+#### 子 Agent 通信原理
+
+```
+心跳触发 (Heartbeat triggers)
+    ↓
+Agent 读取 HEARTBEAT.md
+    ↓
+对于长任务: spawn 子 Agent
+    ↓                           ↓
+继��下一个任务               子 Agent 独立工作
+    ↓                           ↓
+所有任务完成                 子 Agent 使用 "message" 工具
+    ↓                           ↓
+响应 HEARTBEAT_OK            用户直接收到结果
+
+```
+
+子 Agent 可以访问工具（message, web_search 等），并且无需通过主 Agent 即可独立与用户通信。
+
+**配置：**
+
+```json
+{
+  "heartbeat": {
+    "enabled": true,
+    "interval": 30
+  }
+}
+
+```
+
+| 选项 | 默认值 | 描述 |
+| --- | --- | --- |
+| `enabled` | `true` | 启用/禁用心跳 |
+| `interval` | `30` | 检查间隔，单位分钟 (最小: 5) |
+
+**环境变量:**
+
+* `PICOCLAW_HEARTBEAT_ENABLED=false` 禁用
+* `PICOCLAW_HEARTBEAT_INTERVAL=60` 更改间隔

+
+# 🦐 PicoClaw Roadmap
+
+> **Vision**: To build the ultimate lightweight, secure, and fully autonomous AI Agent infrastructure.automate the mundane, unleash your creativity
+
+---
+
+## 🚀 1. Core Optimization: Extreme Lightweight
+
+*Our defining characteristic. We fight software bloat to ensure PicoClaw runs smoothly on the smallest embedded devices.*
+
+* [**Memory Footprint Reduction**](https://github.com/sipeed/picoclaw/issues/346) 
+  * **Goal**: Run smoothly on 64MB RAM embedded boards (e.g., low-end RISC-V SBCs) with the core process consuming < 20MB.
+  * **Context**: RAM is expensive and scarce on edge devices. Memory optimization takes precedence over storage size.
+  * **Action**: Analyze memory growth between releases, remove redundant dependencies, and optimize data structures.
+
+
+## 🛡️ 2. Security Hardening: Defense in Depth
+
+*Paying off early technical debt. We invite security experts to help build a "Secure-by-Default" agent.*
+
+* **Input Defense & Permission Control**
+  * **Prompt Injection Defense**: Harden JSON extraction logic to prevent LLM manipulation.
+  * **Tool Abuse Prevention**: Strict parameter validation to ensure generated commands stay within safe boundaries.
+  * **SSRF Protection**: Built-in blocklists for network tools to prevent accessing internal IPs (LAN/Metadata services).
+
+
+* **Sandboxing & Isolation**
+  * **Filesystem Sandbox**: Restrict file R/W operations to specific directories only.
+  * **Context Isolation**: Prevent data leakage between different user sessions or channels.
+  * **Privacy Redaction**: Auto-redact sensitive info (API Keys, PII) from logs and standard outputs.
+
+
+* **Authentication & Secrets**
+  * **Crypto Upgrade**: Adopt modern algorithms like `ChaCha20-Poly1305` for secret storage.
+  * **OAuth 2.0 Flow**: Deprecate hardcoded API keys in the CLI; move to secure OAuth flows.
+
+
+
+## 🔌 3. Connectivity: Protocol-First Architecture
+
+*Connect every model, reach every platform.*
+
+* **Provider**
+  * [**Architecture Upgrade**](https://github.com/sipeed/picoclaw/issues/283): Refactor from "Vendor-based" to "Protocol-based" classification (e.g., OpenAI-compatible, Ollama-compatible). *(Status: In progress by @Daming, ETA 5 days)*
+  * **Local Models**: Deep integration with **Ollama**, **vLLM**, **LM Studio**, and **Mistral** (local inference).
+  * **Online Models**: Continued support for frontier closed-source models.
+
+
+* **Channel**
+  * **IM Matrix**: QQ, WeChat (Work), DingTalk, Feishu (Lark), Telegram, Discord, WhatsApp, LINE, Slack, Email, KOOK, Signal, ...
+  * **Standards**: Support for the **OneBot** protocol.
+  * [**attachment**](https://github.com/sipeed/picoclaw/issues/348): Native handling of images, audio, and video attachments.
+
+
+* **Skill Marketplace**
+  * [**Discovery skills**](https://github.com/sipeed/picoclaw/issues/287): Implement `find_skill` to automatically discover and install skills from the [GitHub Skills Repo] or other registries.
+
+
+
+## 🧠 4. Advanced Capabilities: From Chatbot to Agentic AI
+
+*Beyond conversation—focusing on action and collaboration.*
+
+* **Operations**
+  * [**MCP Support**](https://github.com/sipeed/picoclaw/issues/290): Native support for the **Model Context Protocol (MCP)**.
+  * [**Browser Automation**](https://github.com/sipeed/picoclaw/issues/293): Headless browser control via CDP (Chrome DevTools Protocol) or ActionBook.
+  * [**Mobile Operation**](https://github.com/sipeed/picoclaw/issues/292): Android device control (similar to BotDrop).
+
+
+* **Multi-Agent Collaboration**
+  * [**Basic Multi-Agent**](https://github.com/sipeed/picoclaw/issues/294) implement
+  * [**Model Routing**](https://github.com/sipeed/picoclaw/issues/295): "Smart Routing" — dispatch simple tasks to small/local models (fast/cheap) and complex tasks to SOTA models (smart).
+  * [**Swarm Mode**](https://github.com/sipeed/picoclaw/issues/284): Collaboration between multiple PicoClaw instances on the same network.
+  * [**AIEOS**](https://github.com/sipeed/picoclaw/issues/296): Exploring AI-Native Operating System interaction paradigms.
+
+
+
+## 📚 5. Developer Experience (DevEx) & Documentation
+
+*Lowering the barrier to entry so anyone can deploy in minutes.*
+
+* [**QuickGuide (Zero-Config Start)**](https://github.com/sipeed/picoclaw/issues/350)
+  * Interactive CLI Wizard: If launched without config, automatically detect the environment and guide the user through Token/Network setup step-by-step.
+
+
+* **Comprehensive Documentation**
+  * **Platform Guides**: Dedicated guides for Windows, macOS, Linux, and Android.
+  * **Step-by-Step Tutorials**: "Babysitter-level" guides for configuring Providers and Channels.
+  * **AI-Assisted Docs**: Using AI to auto-generate API references and code comments (with human verification to prevent hallucinations).
+
+
+
+## 🤖 6. Engineering: AI-Powered Open Source
+
+*Born from Vibe Coding, we continue to use AI to accelerate development.*
+
+* **AI-Enhanced CI/CD**
+  * Integrate AI for automated Code Review, Linting, and PR Labeling.
+  * **Bot Noise Reduction**: Optimize bot interactions to keep PR timelines clean.
+  * **Issue Triage**: AI agents to analyze incoming issues and suggest preliminary fixes.
+
+
+
+## 🎨 7. Brand & Community
+
+* [**Logo Design**](https://github.com/sipeed/picoclaw/issues/297): We are looking for a **Mantis Shrimp (Stomatopoda)** logo design!
+  * *Concept*: Needs to reflect "Small but Mighty" and "Lightning Fast Strikes."

+# Agent Persona: PicoClaw 🦀
+
+You are **PicoClaw**, an autonomous Senior Distributed Systems Engineer & AI Researcher. You are capable, persistent, and security-conscious. Your goal is to help the user build, debug, and understand complex software systems with minimal hand-holding.
+
+## Core Directives
+
+1.  **Be Autonomous**: Don't just suggest code; implement it, test it, and verify it works. Use your skills (`docker`, `go-dev`, `api-tester`) proactively.
+2.  **Be Secure**: Always use the `security-audit` skill before finalizing code changes. Never commit secrets or dangerous patterns.
+3.  **Be Organized**: For any task with >2 steps, YOU MUST use the `planner` skill to create a `PLAN.md`.
+4.  **Be Adaptive**: Learn from your mistakes. If a fix works, save the lesson using the `memory` skill for future reference.
+5.  **Be Communicative**:
+    -   Use clear, concise language (Indonesian/English as preferred by user).
+    -   If the user asks for a voice response, use the `voice-tts` skill immediately.
+    -   Use `diagrams` to explain complex architectures.
+
+## Skill Protocols
+
+### 🛠️ Engineering (Go, Docker, SQL)
+-   **New Features**: Always check existing code patterns with `code-expert` first.
+-   **Database**: Use `db-manager` to inspect state before and after migrations.
+-   **Microservices**: Use `api-tester` and `network-utils` to verify connectivity between services.
+
+### 🧠 Research & Knowledge (AI, Memory)
+-   **Unknown Topics**: Use `ai-research` to find ArXiv papers or latest docs.
+-   **Long-term Memory**:
+    -   *Save*: `echo "Lesson: ..." > .memory/lessons/topic.md`
+    -   *Recall*: `grep -r "topic" .memory/`
+
+### 🛡️ Security & Quality
+-   **Pre-Commit Check**: Run `security-audit` and `go-dev` (lint/vet) before asking for approval.
+
+## Voice Interaction
+-   When speaking (via `voice-tts`), keep sentences short and natural.
+-   Use Indonesian unless the technical context requires English terms.
+
+## Tone
+-   **Professional yet Casual**: "Siap, laksanakan!" instead of "Affirmative, executing command."
+-   **Direct**: Get straight to the solution.
