[Unreleased]

Added

  • Agent tree visualization: SVG tree of tool calls with horizontal layout, bezier edges, status-colored nodes (AgentTree.svelte + agent-tree.ts) (Phase 5)
  • Global status bar showing terminal/agent pane counts, active agents with pulse animation, total tokens and cost (StatusBar.svelte) (Phase 5)
  • Toast notification system with auto-dismiss (4s), max 5 visible, color-coded by type (notifications.svelte.ts + ToastContainer.svelte) (Phase 5)
  • Agent dispatcher toast integration: notifications on agent complete, error, and sidecar crash (Phase 5)
  • Settings dialog with default shell, working directory, and max panes configuration (SettingsDialog.svelte) (Phase 5)
  • Settings persistence: key-value settings table in SQLite, Tauri commands settings_get/set/list, settings-bridge.ts adapter (Phase 5)
  • Keyboard shortcuts: Ctrl+W close focused pane, Ctrl+, open settings dialog (Phase 5)
  • SQLite session persistence with rusqlite (bundled, WAL mode) — sessions table + layout_state singleton (Phase 4)
  • Session CRUD: save, delete, update_title, touch with 7 Tauri commands (Phase 4)
  • Layout restore on app startup — panes and preset restored from database (Phase 4)
  • File watcher backend using notify crate v6 — watches files, emits Tauri events on change (Phase 4)
  • MarkdownPane component with marked.js rendering, Catppuccin-themed styles, and live reload (Phase 4)
  • Sidebar "M" button for opening markdown/text files via file picker (Phase 4)
  • Session bridge adapter for Tauri IPC (session + layout persistence wrappers) (Phase 4)
  • File bridge adapter for Tauri IPC (watch, unwatch, read, onChange wrappers) (Phase 4)
  • Sidecar crash detection — dispatcher listens for process exit, marks running sessions as error (Phase 3 polish)
  • Sidecar restart UI — "Restart Sidecar" button in AgentPane error bar (Phase 3 polish)
  • Auto-scroll lock — disables auto-scroll when user scrolls up, shows "Scroll to bottom" button (Phase 3 polish)
  • Agent restart Tauri command (agent_restart) (Phase 3 polish)
  • Agent pane with prompt input, structured message rendering, stop button, and cost display (Phase 3)

Fixed

  • Svelte 5 rune stores (layout, agents, sessions) renamed from .ts to .svelte.ts — runes only work in .svelte and .svelte.ts files, plain .ts caused "rune_outside_svelte" runtime error (blank screen)
  • Updated all import paths to use .svelte suffix for store modules
  • Node.js sidecar manager (Rust) for spawning and communicating with agent-runner via stdio NDJSON (Phase 3)
  • Agent-runner sidecar: spawns claude CLI with --output-format stream-json for structured agent output (Phase 3)
  • SDK message adapter parsing stream-json into 9 typed message types: init, text, thinking, tool_call, tool_result, status, cost, error, unknown (Phase 3)
  • Agent bridge adapter for Tauri IPC (invoke + event listeners) (Phase 3)
  • Agent dispatcher routing sidecar events to agent session store (Phase 3)
  • Agent session store with message history, cost tracking, and lifecycle management (Phase 3)
  • Keyboard shortcut: Ctrl+Shift+N to open new agent pane (Phase 3)
  • Sidebar button for creating new agent sessions (Phase 3)
  • Rust PTY backend with portable-pty: spawn, write, resize, kill with Tauri event streaming (Phase 2)
  • xterm.js terminal pane with Canvas addon, FitAddon, and Catppuccin Mocha theme (Phase 2)
  • CSS Grid tiling layout with 5 presets: 1-col, 2-col, 3-col, 2x2, master-stack (Phase 2)
  • Layout store with Svelte 5 $state runes and auto-preset selection (Phase 2)
  • Sidebar with session list, layout preset selector, and new terminal button (Phase 2)
  • Keyboard shortcuts: Ctrl+N new terminal, Ctrl+1-4 focus pane (Phase 2)
  • PTY bridge adapter for Tauri IPC (invoke + event listeners) (Phase 2)
  • PaneContainer component with header bar, status indicator, and close button (Phase 2)
  • Terminal resize handling with ResizeObserver and 100ms debounce (Phase 2)
  • v2 project scaffolding: Tauri 2.x + Svelte 5 in v2/ directory (Phase 1)
  • Rust backend stubs: main.rs, lib.rs, pty.rs, sidecar.rs, watcher.rs, session.rs (Phase 1)

  • Node.js sidecar scaffold with NDJSON communication pattern (Phase 1)
  • v2 architecture planning: Tauri 2.x + Svelte 5 + Claude Agent SDK via Node.js sidecar
  • Research documentation covering Agent SDK, xterm.js performance, Tauri ecosystem, and ultrawide layout patterns
  • Phased implementation plan (6 phases, MVP = Phases 1-4)
  • Error handling and testing strategy for v2
  • Documentation structure in docs/ (task_plan, phases, findings, progress)
  • 17 operational rules in .claude/rules/
  • TODO.md for tracking active work
