  "account": "ThinkRail is an open source, innovative IDE developed by JetBrains. It is designed to learn and improve as you use it, providing a more intelligent coding experience. When you open a repository in ThinkRail, it creates a separate git-worktree workspace for that project. This allows multiple agents to run in parallel, each with its own branch and context, ensuring that the main branch remains clean.\n\nThinkRail operates on a spec-first principle, meaning that your projects are structured around a connected graph of spec files. This spec graph lives alongside the code and is maintained by the agent using specialized tools. The agent's intent, or the overall purpose of the project, remains consistent even when you close and reopen the workspace.\n\nA project in ThinkRail is simply any local git repository, while a workspace is a git worktree that is cut from the project. Creating a workspace is as easy as one click, and you can list and manage workspaces in the rail interface. The workspace is completely isolated from the project, making it easy to dispose of without any hassle.\n\nThe ThinkRail interface allows you to watch the agent in action, either working alongside you or independently. This real-time interaction provides a unique, immersive coding experience. ThinkRail is powered by the pi coding agent, which runs within the IDE and manages models, skills, compaction, and cost. All of this information is stored in a SPEC.md file with frontmatter that links it into the spec graph.\n\nThe bundled pi-spec-graph extension provides the agent with specialized tools to search, navigate, and maintain the spec graph. The Specs tab displays a live graph of your worktree, making it easy to understand an area of the codebase and formulate the next task based on that knowledge. The agent ensures that the specs are kept up-to-date and accurate as the code evolves.\n\nTo get started with ThinkRail, extract the provided archive and run the installer. Make sure your system meets the native library requirements. Then, run the local launcher and open the browser UI by executing the \"thinkrail\" command. Keep in mind that ThinkRail requires git and an authenticated pi provider for full functionality.",
