Cogento is an open-source AI-powered coding agent built for VS Code. It combines a conversational chat interface with direct workspace interactions, allowing you to build, debug, and refactor code with the power of LLMs.
🚀 Features
Multi-Provider Support: Switch seamlessly between OpenAI (GPT-4o), Anthropic (Claude 3.5), and Google Gemini (featuring the latest Gemini 3 Pro/Flash Preview models).
Workspace Context Awareness: Cogento automatically indexes your project structure and tech stack on startup, providing the LLM with immediate architectural context.
Advanced Agentic Architecture: Cogento acts like a real developer:
Surgical Code Editing: Uses search-and-replace block tracking to apply targeted AST diffs without regenerating massive files.
Live Diagnostics: Automatically runs linting checks against the VS Code syntax engine after editing a file, reading warning and error traces to self-correct its own code.
Deep Workspace Indexing: Leverages native VS Code findFiles and regex text parsing for whole-project structural awareness.
AST Symbol Navigation: Taps into the Language Server Protocol to instantly find Definitions and References in the editor.
Visual Terminal Control: Spawns visible Pseudo-TTY vscode.window instances to safely run dev servers, builds, and bash scripts.
Interactive Chat:
Copy Code: One-click copy for all generated blocks via inline icons.
Auto-complete Mentions: Type @ to suggest and include workspace files and folders in your prompt.
Restore & Retry: Quickly edit previous messages, or use the robust "Retry Request" recovery button if a complex LLM generation times out.
Top-Bar Controls: Instantly access your API keys and provider configurations via the new Header Settings gear icon.
Multimodal Support: Attach images to your prompts for visual context.
Clean UI: A borderless, theme-aware layout that fits perfectly into your VS Code workspace with real-time "Working..." and chronological Tool Action statuses.
Conversation History: Persistent chat history with multi-chat management.
