# Changelog All notable changes to the AI Agentic Data Stack Framework - Community Edition will be documented in this file. The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/), and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html). ## [1.1.2] - 2024-07-24 ### 🛠️ Interactive Shell Mode Fixes #### Command Routing Improvements - **Fixed interactive shell command routing**: Resolved critical issue where `*task` commands were not properly routed to active agents - **Fixed `this.getAvailableTasks is not a function` error**: Corrected method name from `getAvailableTasks()` to `listTasks()` in agent-orchestrator.js:73 - **Fixed `this.handleCustomCommand is not a function` error**: Added missing `handleCustomCommand()` method to Agent class for processing custom commands like `*analyze-data`, `*create-dashboard`, `*define-metrics` #### Agent System Enhancements - **Improved command delegation**: Fixed CommandHandler to properly delegate task execution to `this.activeAgent.executeTask()` instead of bypassing agent logic - **Enhanced error handling**: Better error messages when task files are not found, with helpful path information - **Global installation compatibility**: Fixed issues with globally installed package not reflecting local development changes #### Documentation Updates - **Updated agent names**: Changed Sam → Riley (Data Analyst), Alex → Morgan (Data Product Manager) throughout all documentation - **Interactive shell examples**: Updated all command examples to use `agentic-data interactive` and `@agent-name` activation format - **Version alignment**: Updated all version references from 1.1.1 to 1.1.2 across README.md and docs/ #### Technical Improvements - **Command flow validation**: Ensured proper command routing from user input through CommandHandler to Agent execution - **Session persistence**: Improved interactive shell session management and agent context preservation - **Error message clarity**: Enhanced error messages to provide actionable guidance to users ### ✅ **Resolved Issues** - Interactive shell commands (`*task`, `*analyze-data`, `*create-dashboard`) now work correctly in `agentic-data interactive` mode - Agent activation using `@agent-name` format works seamlessly - Task execution properly shows available tasks when no task name provided - Custom agent commands execute successfully without "not a function" errors - Global npm installation now reflects the latest fixes --- ## [1.1.1] - 2024-07-24 ### 🔧 Critical Fixes #### Agent Interaction System - **Fixed `handleCustomCommand is not a function` error**: Added missing method in AgentOrchestrator for processing agent-specific commands like `*analyze-data`, `*build-pipeline`, `*segment-customers` - **Fixed task execution failures**: Enhanced `executeTask` method to handle empty task names and provide helpful task lists - **Fixed template selection**: Improved `createDocument` method to show available templates when no template name provided - **Enhanced workflow execution**: Workflow steps now actually activate agents and execute tasks instead of just marking as completed #### User Experience Improvements - **Better error messages**: More informative error messages with suggestions for available commands and tasks - **Task discovery**: `*task` command now shows list of available tasks when called without arguments - **Template discovery**: `*create-doc` command now shows available templates when called without arguments - **Agent command validation**: Proper validation and routing for all agent-specific commands #### Technical Improvements - **Added `getAvailableTemplates()` method**: Dynamic template discovery for better user experience - **Enhanced error handling**: Graceful error handling in workflow execution with continue/abort options - **Improved command routing**: Better logic for handling custom commands and task execution ### ✅ **Resolved Issues** - Agent commands (`*analyze-data`, `*segment-customers`, etc.) now execute properly - Task execution with empty parameters now shows helpful guidance instead of failing - Template creation process works correctly with proper template selection - Workflow steps now provide meaningful interaction instead of just completing automatically --- ## [1.1.0] - 2024-07-24 ### 🚀 Major Features Added #### Interactive AI Agent System - **Interactive Agent Activation**: New `agentic-data agent ` command for persistent agent sessions -
