Workbench

Every part of the Dev workbench is interactive: panels resize by dragging separators, collapse with the toggles in the tab bar, and remember their state.

Project selector

Top right of the workbench. It works like a folder picker in a code editor:

  • Recent projects - the last projects you opened, one click to switch back.
  • Quick access roots - home directory, filesystem root, and (under WSL) Windows drives (for example C: mounted in WSL).
  • Browse - a folder browser dialog to navigate the filesystem.
  • Type a path - paste or type any absolute path (for example ~/app, C:\Users\me\proj, or a mounted server path).

Selecting a project sets the workspace scope of the active agent session: the file tree, terminals, diagnostics, git status, and every agent tool operate inside that folder. If no agent session exists yet, one is created automatically with that scope.

Environments detected: Linux, WSL (with Windows interop), macOS, Windows.

Explorer

  • Lazy-loaded file tree of the project.
  • Create, rename, and delete files and folders.
  • Click a file to open it in an editor tab.
  • Collapsible with the panel toggle; resizable by dragging its edge.

Editor

  • CodeMirror-based, with syntax highlighting per language and dark/light themes.
  • Multiple tabs, unsaved-draft indicator, save with the toolbar button or Ctrl/Cmd+S.
  • Inline diagnostics: Python files are checked with Ruff, JSON files with a parser. Errors and warnings are underlined (squiggles) and listed in the status bar. Diagnostics refresh on open and on save.
  • Files mentioned by the agent in chat are clickable and open directly in the editor.

Terminals

  • Real PTY terminals inside the workbench, multiple tabs.
  • Shell picker: bash, sh, zsh when available - and under WSL, Windows interop shells: PowerShell and cmd.exe.
  • Full interactivity (arrows, ctrl-keys, TUI apps), resizable and collapsible panel.
  • The agent's own shell executions stream into the chat; your terminals are yours.

Preview / Browser

  • Built-in preview pane for running web apps (dev servers, etc.).
  • Switch the center area between editor and browser modes; the preview URL is editable and reloadable.
  • Publish (next to Open) exposes the local port through a Cloudflare Quick Tunnel and shows a public *.trycloudflare.com URL. Details: Publish preview.

Mobile preview

  • Center tab Mobile (next to web Preview): live Android screen via adb, logcat, FPS / memory / CPU.
  • Click = tap, drag = swipe; Back / Home / Recents in the toolbar.
  • Start with /mobile android or the Run Mobile button, then Start preview once a device is online.
  • Details: Mobile and the full reference docs/mobile.md.

Agent chat panel

  • Right-hand panel, resizable by dragging the separator and hideable with the panel toggle.
  • Multiple agents: each tab is an independent chat session with its own agent loop, memory, name, and workspace scope. Create with + (you are prompted for a name), rename by double-clicking the tab, close with ×.
  • A green dot marks agents that are currently running.
  • The chat renders the agent's work live: reasoning steps, tool calls, file diffs, and command output as structured blocks in the thread.

Status bar

Bottom of the workbench:

ItemMeaning
EnvironmentWSL, Linux, macOS… detected from the backend
Gitcurrent branch, dirty indicator, ahead/behind counts (refreshes periodically and on save)
Projectactive project name
Active filefilename plus its error/warning counts from diagnostics

Checkpoints

Before every prompt, Navin snapshots the session (conversation + tracked file contents). Use /checkpoint list, /checkpoint restore <name> [all|chat|code], /checkpoint save [note], /checkpoint delete <name>. Checkpoints complement git - they are quick rewind points, not version control.
