+# Roadmap 2026 Implementation Summary
+
+**Date:** February 13, 2026  
+**Session:** Continue Roadmap 2026 Implementations  
+**PR Branch:** `copilot/continue-roadmap-2026-implementations`
+
+## Overview
+
+This session implemented high-priority items from the Go Micro Roadmap 2026, focusing on Q2 2026 "Agent Developer Experience" features. We've successfully completed the majority of Q2 deliverables, putting the project **3-4 months ahead of schedule**.
+
+## What Was Implemented
+
+### 1. MCP CLI Commands (Q2 2026 Features)
+
+#### `micro mcp docs` Command
+Generates comprehensive documentation for all MCP tools.
+
+**Features:**
+- Markdown format for human-readable docs
+- JSON format for machine-readable output
+- Extracts descriptions, examples, and scopes from service metadata
+- Save to file with `--output` flag
+
+**Usage:**
+```bash
+micro mcp docs                          # Markdown to stdout
+micro mcp docs --format json            # JSON format
+micro mcp docs --output mcp-tools.md    # Save to file
+```
+
+#### `micro mcp export` Commands
+Exports MCP tools to various agent framework formats.
+
+**Supported Formats:**
+
+1. **LangChain** - Python LangChain tool definitions
+   ```bash
+   micro mcp export langchain --output langchain_tools.py
+   ```
+   - Generates complete Python code with LangChain Tool definitions
+   - Includes HTTP gateway integration code
+   - Ready to use with LangChain agents
+   - Proper function naming and type hints
+
+2. **OpenAPI** - OpenAPI 3.0 specification
+   ```bash
+   micro mcp export openapi --output openapi.json
+   ```
+   - Generates OpenAPI 3.0 spec
+   - Includes security schemes for bearer auth
+   - Tool scopes mapped to security requirements
+   - Compatible with Swagger UI and OpenAI GPTs
+
+3. **JSON** - Raw JSON tool definitions
+   ```bash
+   micro mcp export json --output tools.json
+   ```
+   - Complete tool metadata
+   - Includes descriptions, examples, scopes
+   - Useful for custom integrations
+
+**Implementation:**
+- File: `cmd/micro/mcp/mcp.go` (~500 lines added)
+- Tests: `cmd/micro/mcp/mcp_test.go` (updated)
+- Examples: `cmd/micro/mcp/EXAMPLES.md` (9KB comprehensive guide)
+
+### 2. LangChain Python SDK (High Priority Q2 Feature)

+2. **Authentication & Security**
+   - Bearer token authentication
+   - Configurable SSL verification
+   - Proper error handling for auth failures
+
+3. **Configuration**

+   - Customizable timeout, retry count, retry delay
+   - Gateway URL and auth token management
+
+4. **Error Handling**

+```
+
+#### Usage Examples
+
+**Basic Usage:**
+```python
+from langchain_go_micro import GoMicroToolkit
+from langchain.agents import initialize_agent
+from langchain_openai import ChatOpenAI
+
+# Connect to MCP gateway
+toolkit = GoMicroToolkit.from_gateway("http://localhost:3000")
+
+# Get tools
+tools = toolkit.get_tools()
+
+# Create agent
+llm = ChatOpenAI(model="gpt-4")
+agent = initialize_agent(tools, llm, verbose=True)
+
+# Use agent!
+result = agent.run("Create a user named Alice")
+```
+
+**Advanced Features:**
+```python
+# With authentication
+toolkit = GoMicroToolkit.from_gateway(
+    "http://localhost:3000",
+    auth_token="your-bearer-token"
+)
+
+# Filter by service
+user_tools = toolkit.get_tools(service_filter="users")
+
+# Select specific tools
+tools = toolkit.get_tools(include=["users.Users.Get", "users.Users.Create"])
+
+# Exclude tools
+tools = toolkit.get_tools(exclude=["users.Users.Delete"])
+
+# Call tools directly
+result = toolkit.call_tool("users.Users.Get", '{"id": "user-123"}')
+```
+
+**Multi-Agent Workflows:**
+```python
+# Specialized agents for different services
+user_agent = initialize_agent(
+    toolkit.get_tools(service_filter="users"),
+    ChatOpenAI(model="gpt-4")
+)
+
+order_agent = initialize_agent(
+    toolkit.get_tools(service_filter="orders"),
+    ChatOpenAI(model="gpt-4")
+)
+
+# Coordinate between agents
+user = user_agent.run("Create user Alice")
+order = order_agent.run(f"Create order for {user}")
+```
