Overview
A major release focused on reliability, performance, and user experience. Nexus v5 introduces a deterministic hook system, dramatically improved session continuity, and a streamlined onboarding process.
Key Innovations
🚀 Deterministic Hook System
- Instant startup — Context loads in milliseconds, not seconds
- 100% reliable — System always loads correctly, no more failed initializations
- Safe execution — Prevents problematic commands automatically
- Smart context injection — Only loads what's needed for current state
🔄 Cross-Compaction Continuity
- Resume-context files — Claude dynamically reloads exactly what it needs after context resets
- No more re-explaining — Session continuity survives context window limits
- Progress preserved — Build state, step progress, and learnings persist automatically
📋 Enhanced Build Planning
- Extended discovery phase — More intelligent questioning to capture real requirements
- Mental model review — Pre-mortem, Inversion, JTBD, Pareto applied to every plan
- Existing work detection — Automatically finds and connects to previous builds and files
- Context aggregation — Learns from your existing content, styles, and examples
🎯 Streamlined Onboarding
- Context upload — Drop in existing files, docs, or examples and Claude learns from them
- Goal-focused setup — Quick personalization without lengthy configuration
- Progressive learning — System teaches itself as you work, not through tutorials
🔌 10-Minute Integrations
- Slack, HubSpot, Google (Gmail, Calendar, Drive, Sheets, Docs), Airtable, Langfuse, NotebookLM, HeyReach, Gemini
- Guided setup with API discovery built in
- Add any REST API with
"add integration"
📚 Open Skill Ecosystem

- Drop any skill into
03-skills/and use immediately - Create and share your own workflows
README Rewrite
Complete rewrite focused on clarity:
- Removed marketing fluff, focused on what Nexus actually does
- Added quick example showing full discovery → mental model → execution flow
- Highlighted key differentiators: hooks, continuity, mental models, context upload
