|
## Phase 1: Project Scaffolding [status: complete] — MVP
|
|
|
|
- [x] Create feature branch `v2-mission-control`
|
|
- [x] Initialize Tauri 2.x project with Svelte 5 frontend
|
|
- [x] Project structure (see below)
|
|
- [x] Basic Tauri window with Catppuccin Mocha CSS variables
|
|
- [x] Verify Tauri builds and launches on target system
|
|
- [x] Set up dev scripts (dev, build, lint)
|
|
|

## Phase 2: Terminal Pane + Layout [status: complete] — MVP
|
|
|
|
### Layout (responsive)
|
|
|
|
**32:9 (5120px) — full density:**
|
|
```
|
|
+--------+------------------------------------+--------+
|
|
|Sidebar | 2-4 panes, CSS Grid, resizable | Right |
|
|
| 260px | | 380px |
|
|
+--------+------------------------------------+--------+
|
|
```
|
|
|
|
**16:9 (1920px) — degraded but functional:**
|
|
```
|
|
+--------+-------------------------+
|
|
|Sidebar | 1-2 panes | (right panel collapses to overlay)
|
|
| 240px | |
|
|
+--------+-------------------------+
|
|
```
|
|
|
|
- [x] CSS Grid layout with sidebar + main area + optional right panel
|
|
- [x] Responsive breakpoints (ultrawide / standard / narrow)
|
|
- [ ] Pane resize via drag handles (deferred — current presets sufficient for MVP)
|
|
- [x] Layout presets: 1-col, 2-col, 3-col, 2x2, master+stack
|
|
- [ ] Save/restore layout to SQLite (Phase 4)
|
|
- [x] Keyboard: Ctrl+1-4 focus pane, Ctrl+N new terminal
|
|
|
|
### Terminal
|
|
- [x] xterm.js with Canvas addon (explicit — no WebGL dependency)
|
|
- [x] Catppuccin Mocha theme for xterm.js
|
|
- [x] PTY spawn from Rust (portable-pty), stream to frontend via Tauri events
|
|
- [x] Terminal resize -> PTY resize (100ms debounce)
|
|
- [ ] Copy/paste (Ctrl+Shift+C/V) — deferred
|
|
- [x] SSH session: spawn `ssh` command in PTY (via shell args)
|
|
- [x] Local shell: spawn user's $SHELL
|
|
- [x] Claude Code CLI: spawn `claude` in PTY (via shell args)
|
|
|
|
**Milestone: After Phase 2, we have a working multi-pane terminal.** Usable as a daily driver even without agent features.
|
|
|
|

|
|
|
|
## Phase 3: Agent SDK Integration [status: complete] — MVP
|
|
|
|
### Backend
|
|
- [x] Node.js sidecar: spawns `claude` CLI with `--output-format stream-json` (not Agent SDK query() — avoids npm dep + version churn)
|
|
- [x] Sidecar communication: Rust spawns Node.js, stdio NDJSON
|
|
- [x] Sidecar lifecycle: auto-start on app launch, shutdown on exit
|
|
- [x] Sidecar lifecycle: detect crash, offer restart in UI (agent_restart command + restart button)
|
|
- [x] Tauri commands: agent_query, agent_stop, agent_ready, agent_restart
|
|
|
|
### Frontend
|
|
- [x] SDK message adapter: parses stream-json into 9 typed AgentMessage types (abstraction layer)
|
|
- [x] Agent bridge: Tauri IPC adapter (invoke + event listeners)
|
|
- [x] Agent dispatcher: singleton routing sidecar events to store, crash detection
|
|
- [x] Agent store: session state, message history, cost tracking (Svelte 5 $state)
|
|
- [x] Agent pane: renders structured messages
|
|
- [x] Text -> plain text (markdown rendering deferred)
|
|
- [x] Tool calls -> collapsible cards (tool name + input)
|
|
- [x] Tool results -> collapsible cards
|
|
- [x] Thinking -> collapsible details
|
|
- [x] Init -> model badge
|
|
- [x] Cost -> USD/tokens/turns/duration summary
|
|
- [x] Errors -> highlighted error card
|
|
- [ ] Subagent spawn -> tree node + optional new pane (Phase 5)
|
|
- [x] Agent status indicator (starting/running/done/error)
|
|
- [x] Start/stop agent from UI (prompt form + stop button)
|
|
- [x] Auto-scroll with scroll-lock on user scroll-up
|
|
- [ ] Session resume (SDK `resume: sessionId`)
|
|
- [x] Keyboard: Ctrl+Shift+N new agent
|
|
- [x] Sidebar: agent session button
|
|
|
|
**Milestone: After Phase 3, we have the core differentiator.** SDK agents run in structured panes alongside raw terminals.
|
|
|

|
|
|
|
## Phase 4: Session Management + Markdown Viewer [status: complete] — MVP
|
|
|
|
### Sessions
|
|
- [x] SQLite persistence for sessions (rusqlite with bundled feature)
|
|
- [x] Session types: terminal, agent, markdown (SSH via terminal args)
|
|
- [x] Session CRUD: save, delete, update_title, touch (last_used_at)
|
|
- [ ] Session groups/folders (deferred — not needed for MVP)
|
|
- [x] Remember last layout on restart (preset + pane_ids in layout_state table)
|
|
- [x] Auto-restore panes on app startup (restoreFromDb in layout store)
|
|
|
|
### Markdown Viewer
|
|
- [x] File watcher (notify crate v6) -> Tauri events -> frontend
|
|
- [x] Markdown rendering (marked.js)
|
|
- [x] Syntax highlighting (Shiki) — added in Phase 5 (highlight.ts, 13 preloaded languages)
|
|
- [x] Open from sidebar (file picker button "M")
|
|
- [x] Catppuccin-themed markdown styles (h1-h3, code, pre, tables, blockquotes)
|
|
- [x] Live reload on file change
|
|
|
|
**Milestone: After Phase 4 = MVP ship.** Full session management, structured agent panes, terminal panes, markdown viewer.
|
|
|

|
|
|
|
## Phase 5: Agent Tree + Polish [status: complete] — Post-MVP
|
|
|
|
- [x] Agent tree visualization (SVG, compact horizontal layout) — AgentTree.svelte + agent-tree.ts utility
|
|
- [ ] Click tree node -> focus agent pane (onNodeClick prop exists, not wired)
|
|
- [ ] Aggregate cost per subtree (subtreeCost util exists, not displayed in UI)
|
|
- [x] Global status bar (terminal/agent counts, active agents pulse, token/cost totals) — StatusBar.svelte
|
|
- [x] Notification system (toast: success/error/warning/info, auto-dismiss 4s, max 5) — notifications.svelte.ts + ToastContainer.svelte
|
|
- [x] Agent dispatcher toast integration (agent complete, error, sidecar crash notifications)
|
|
- [x] Global keyboard shortcuts — Ctrl+W close focused pane, Ctrl+, open settings
|
|
- [x] Settings dialog (default shell, cwd, max panes, theme flavor) — SettingsDialog.svelte + settings-bridge.ts
|
|
- [x] Settings backend — settings table in SQLite (session.rs), Tauri commands settings_get/set/list (lib.rs)
|
|
- [x] ctx integration — read-only access to ~/.claude-context/context.db (ctx.rs, ctx-bridge.ts, ContextPane.svelte)
|
|
- [x] SSH session management — CRUD in SQLite (SshSession struct, SshDialog.svelte, SshSessionList.svelte, ssh-bridge.ts)
|
|
- [x] Catppuccin theme flavors — Latte/Frappe/Macchiato/Mocha selectable (themes.ts, theme.svelte.ts)
|
|
- [x] Detached pane mode — pop-out terminal/agent into standalone windows (detach.ts, App.svelte)
|
|
- [x] Syntax highlighting — Shiki integration for markdown + agent messages (highlight.ts, shiki dep)
|
|
|
|
---
|
|
|
|
## Phase 6: Packaging + Distribution [status: complete] — Post-MVP
|
|
|
|
- [x] install-v2.sh — build-from-source installer with dependency checks (Node.js 20+, Rust 1.77+, system libs)
|
|
- Checks: WebKit2GTK, GTK3, GLib, libayatana-appindicator, librsvg, openssl, build-essential, pkg-config, curl, wget, FUSE
|
|
- Prompts to install missing packages via apt
|
|
- Builds with `npx tauri build`, installs binary as `bterminal-v2` in `~/.local/bin/`
|
|
- Creates desktop entry and installs SVG icon
|
|
- [x] Tauri bundle configuration — targets: `["deb", "appimage"]`, category: DeveloperTool
|
|
- .deb depends: libwebkit2gtk-4.1-0, libgtk-3-0, libayatana-appindicator3-1
|
|
- AppImage: bundleMediaFramework disabled
|
|
- [x] Icons regenerated from bterminal.svg — RGBA PNGs (32x32, 128x128, 128x128@2x, 512x512, .ico)
|
|
- [x] GitHub Actions release workflow (`.github/workflows/release.yml`)
|
|
- Triggered on `v*` tags, Ubuntu 22.04 runner
|
|
- Caches Rust and npm dependencies
|
|
- Builds .deb + AppImage, uploads as GitHub Release artifacts
|
|
- [x] Build verified: .deb (4.3 MB), AppImage (103 MB)
|
|
- [x] Auto-updater plugin integrated (tauri-plugin-updater Rust + @tauri-apps/plugin-updater npm + updater.ts)
|
|
- [ ] Auto-update signing key + update server setup (needed for full auto-update flow)
|
|
|
|
