RunMaestro/Maestro v0.16.4-RC

v0.16.4-RC | Maestro Cue

on GitHub

🪄 Maestro Cue is a new trigger based cross-agent orchestration capability. Heartbeats, GitHub issues / PRs, file system monitors and other data sources can result in your agents coming to life and passing work between one another.

💻 Major shell upgrade. We now launch a full-featured xterm terminal as a tab alongside your existing AI and file preview tabs. You can open multiple terminals and rename the terminal tabs as well.

Smaller Changes in 0.16.4

• Token-efficient system prompt delivery — Claude Code now receives Maestro context via --append-system-prompt instead of embedding in user messages, reducing token overhead on every spawn 🎯
• Files Pane Icon Theme setting — choose between Default (Lucide) and Rich (Material Icon Theme–style SVGs) for file and folder icons in the right sidebar 🎨
• Publish to Gist button on AI messages — share any AI response as a GitHub Gist directly from the message action bar 📤
• Cue pipeline editor fully conforms to app theme — ~100 hardcoded colors replaced with theme-aware equivalents across 28 components 🎨
• Cue pipeline context menu and settings panel now dismiss on click-outside and Escape 🩹
• Cue node drag stabilized in All Pipelines view — no more pipeline overlap or jump on drag 🩹
• Cue duplicate agents now render as separate nodes in pipeline chains 🔗
• Cue chain edge sources resolved correctly before overwriting sessionToNode mapping 🩹
• Right-click context menu on file references in AI chat with Copy Path and Open actions 📂
• Lightbox image copy-to-clipboard now uses Electron native clipboard API for reliable cross-platform support 📋
• Jump to Nearest Terminal rebound to ⌥⌘J to avoid browser shortcut conflict ⌨️
• File explorer stats bar now honors local ignore patterns and .gitignore 📊
• Silent .catch(() => {}) patterns replaced with error logging for better Sentry visibility 🛡️
• Group chat addParticipant made idempotent and openExternal URL validation hardened 🔒
• Windows system prompt delivery uses temp files to avoid CLI argument length limits 🖥️
• Unique temp file per spawn prevents race conditions on rapid agent respawns 🩹
• Drawfinity added to the Symphony registry 🎵
• Spec-Kit documentation updated with prerequisites and setup instructions 📝
