Detect subagent tool_call events (Agent/Task/dispatch_agent), auto-spawn
child agent panes with parent/child navigation. Messages with parentId
are routed to child panes; parent session keeps its own messages.
- agents.svelte.ts: parent/child hierarchy fields, findChildByToolUseId,
getChildSessions, parent-aware createAgentSession/removeAgentSession
- agent-dispatcher.ts: SUBAGENT_TOOL_NAMES detection, toolUseToChildPane
routing map, spawnSubagentPane with auto-grouping under parent title
- AgentPane.svelte: parent link bar (SUB badge), children bar (chips
with status colors), clickable navigation between parent/child
- SessionList.svelte: subagent panes show arrow icon instead of asterisk
Refactor SidecarManager to use SidecarCommand struct abstracting
runtime choice. resolve_sidecar_command() prefers Deno (runs TS
directly, no build step), falls back to Node.js if deno not in PATH.
Both runners bundled in tauri.conf.json resources. Set auto-update
signing pubkey in updater config.
Add group_name column to sessions table with ALTER TABLE migration,
setPaneGroup in layout store, grouped sidebar rendering with Svelte 5
snippets, and right-click to assign group via prompt dialog.
Experimental agent-runner-deno.ts as drop-in replacement for Node.js sidecar.
Uses Deno.Command for claude CLI subprocess, TextLineStream for NDJSON parsing.
Same stdio NDJSON protocol. Compiles to single binary via deno compile.
Not yet integrated with Rust SidecarManager.
Build-from-source installer (install-v2.sh) with dependency checks for
Node.js 20+, Rust 1.77+, and system libraries. Tauri bundle config for
.deb and AppImage targets. GitHub Actions workflow builds and uploads
release artifacts on version tags. Icons regenerated as RGBA PNGs.
Agent tree visualization (SVG) with horizontal layout and bezier edges.
Global status bar with pane counts, active agents pulse, token/cost totals.
Toast notification system with auto-dismiss and agent dispatcher integration.
Settings dialog with SQLite persistence for shell, cwd, and max panes.
Keyboard shortcuts: Ctrl+W close pane, Ctrl+, open settings.
Phase 3 polish: dispatcher listens for sidecar-exited events and marks
running sessions as error. AgentPane shows "Restart Sidecar" button on
error. Auto-scroll disables when user scrolls >50px from bottom with
"Scroll to bottom" button. Added agent_restart Tauri command.
Svelte 5 $state/$derived runes only work in .svelte and .svelte.ts
files. The stores had plain .ts extensions, causing a blank screen with
"rune_outside_svelte" runtime error. Renamed all three store files and
updated import paths across 5 consuming files.
Replace Agent SDK stub with working implementation that spawns
claude CLI with --output-format stream-json, manages multiple
sessions via Map<sessionId, ChildProcess>, and forwards NDJSON
events to Rust backend. Supports query, stop, and graceful shutdown.
