+# 🦐 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."
