+### Agent Skills
+
+The **MS-Agent Skill Module** is **Implementation** of [Anthropic-Agent-Skills](https://platform.claude.com/docs/en/agents-and-tools/agent-skills) Protocol.
+
+#### 🔍 Intelligent Skill Retrieval
+- **Hybrid Search**: Combines FAISS dense retrieval with BM25 sparse retrieval
+- **LLM-based Filtering**: Uses LLM to filter and validate skill relevance
+- **Query Analysis**: Automatically determines if skills are needed for a query
+
+#### 📊 DAG-based Execution
+- **Dependency Management**: Builds execution DAG based on skill dependencies
+- **Parallel Execution**: Runs independent skills concurrently
+- **Input/Output Linking**: Automatically passes outputs between dependent skills
+
+#### 🧠 Progressive Skill Analysis
+- **Two-phase Analysis**: Plan first, then load resources
+- **Incremental Loading**: Only loads required scripts/references/resources
+- **Context Optimization**: Minimizes token usage while maximizing understanding
+- **Auto Bug Fixing**: Analyzes errors and attempts automatic fixes
+
+#### 🔒 Secure Execution Environment
+- **Docker Sandbox**: Isolated execution using [ms-enclave](https://github.com/modelscope/ms-enclave) containers
+- **Local Execution**: Controlled local execution with RCE prevention
+- **Security Checks**: Pattern-based detection of dangerous code
+
+#### 🔄 Self-Reflection & Retry
+- **Error Analysis**: LLM-based analysis of execution failures
+- **Auto-Fix**: Attempts to fix code based on error messages
+- **Configurable Retries**: Up to N retry attempts with fixes
+
+
+For more details, please refer to [**MS-Agent Skills**](ms_agent/skill/README.md).
