## What it is
Sidecar is a terminal UI application that hosts AI coding agents in embedded interactive terminals alongside split panes for git diffs, file trees, task issues, and Jira/GitHub resources. It consolidates the agentic development workflow—running agents, reviewing changes, and managing tasks—into a single shell.

## Use cases
- run claude code in a terminal with diffs side by side
- monitor ai coding agent sessions across projects
- review git diffs while an agent works
- manage tasks with td next to my coding agent
- open files and issues in split panes from the terminal
- replace my editor with a terminal-based agent workspace

## When to choose
- you use CLI coding agents like Claude Code, Codex, or Gemini daily and want diffs, files, and tasks in one view
- you want to monitor agent sessions across multiple projects
- you prefer terminal-first workflows over IDEs

## When to avoid
- you need a full GUI IDE with rich editor features
- you work on Windows without WSL
- you don't use AI coding agents in your workflow
