AgentHub (also known as Maestro) is an Electron desktop application that orchestrates a virtual software development team of 46 AI agents powered by Claude Code CLI. The system enforces a 'Harness Engineering' methodology: Skills (standardized slash commands), Hooks (pre/post tool interceptors), Gates (quality checkpoints G0–G6), and FileWatchers (auto-sync markdown files to database). The GUI is intentionally limited to monitoring and three core operations—most workflow is driven by slash commands within Claude Code sessions. Architecture follows a three-layer pattern: Vue 3 + TypeScript renderer communicates via Electron IPC (contextBridge) to a main process with ~16 singleton services (session-manager, task-manager, gate-keeper, hook-manager, etc.). Persistence uses sql.js (SQLite in-memory) with a debounced disk save and 13 migrations. The source of truth is markdown files in `.knowledge/` and `.tasks/` directories, which are watched by chokidar and synced to the database. The app supports bilingual UI (zh-TW/en) and runs on Windows, macOS, and Linux. Key features include: sprint-based project management with task dependency tracking, interactive terminal sessions (xterm.js + node-pty), cost tracking per session, Git integration, a gate pipeline with review workflows, and a skill/hook management system with hash-based idempotent deployment. The codebase is well-structured with reusable components and services, though it shows some technical drift (alpha dependencies, brand name mismatch, Windows-specific paths) and high complexity from the extensive agent definitions and knowledge base.
