Three-Step User Flow

Beast Computer distills a complex AI workspace into three steps:

Login — Premium dark login page, username/password auth with session cookies
Connect Claude — One-click OAuth flow, full-screen onboarding overlay
Chat — Type a message, Claude works on it, see live output in terminal panel

After OAuth, the computer auto-starts. The user never sees internal state names like "created" or "stopped".

Tech Stack

Backend

  • Go + Cobra CLI framework
  • HTMX for interactivity (no React build)
  • WebSocket terminal via xterm.js
  • SSE for live chat delivery
  • Cookie session auth
  • File-based JSON state (roster, tasks, experts)
  • Markdown as agent mind (charter, playbook, kanban)

Shipped Phases

  • Phase 0 — Foundation (login, dashboard, terminal)
  • Phase 5.0 — Agent Identity (roster, CLAUDE.md gen)
  • Phase 5.1 — Task Model (JSON + kanban.md)
  • Phase 5.2 — Agent Bus (messages, inbox/outbox)
  • Phase 5.3 — Delegation (task graph, subtasks)
  • Phase 5.4 — Learning System (playbook.md)
  • Phase 5.5 — Agent Templates (catalog + install)
  • Phase 5.6 — Agent Humanization (home dirs, auto-approve)
  • Phase 5.7 — Expert Agent Store (expertise, knowledge, store)

4 UX Quality Assessment

Design System Consistency

Strengths

  • Consistent dark theme with brand color accents
  • Glass card effect with backdrop blur throughout

Areas for Improvement

  • No loading skeletons for HTMX fragment swaps
  • Sidebar panels could benefit from transition animations
  • Empty states in some panels lack illustrations

Summary

Beast Computer delivers a clean, focused product: a personal cloud computer powered by Claude AI. The three-step flow (Login → Connect → Chat) achieves genuine simplicity. The design system is consistent with premium dark theme, glass effects, and smooth animations. The agent management system (roster, tasks, knowledge, expert store) provides depth without complexity. All 20 feature areas have UI + API + E2E coverage. Three code quality issues were found and fixed during audit. Security boundaries are tested (XSS, path traversal, auth). Mobile layout works with bottom tab bar. The codebase is clean Go with no external JS framework dependencies.
