Features

🔀 Mode Selector

Switch between specialized agent modes inspired by Kilo Code:

Mode Description Icon
Architect Plan system architecture and create project roadmaps 🏗️
Code Implementation, refactoring, and production-ready code 💻
Debug Trace issues, read error logs, and suggest fixes 🐛
Ask Query and explain existing codebases without modifying ❓
Proactive Proactive always-on mode — background analysis on file saves ⚡

🐝 Swarm Coordinator

Dispatch parallel tasks to specialized agents:

  • Explore — Codebase patterns, file structures, ast-grep
  • Librarian — Remote repos, official docs, GitHub examples
  • Oracle — Architecture, debugging, complex logic
  • Artistry — Non-conventional problems, different approaches

🐛 BUDDY Gamification

A pet companion in your status bar that:

  • Levels up on commits (+25 XP)
  • Celebrates test passes (+15 XP)
  • Reacts to errors and failures with mood changes
  • Shows XP, level, and last action on hover

🧠 Memory Consolidation

Automatic context loading from:

  • AGENTS.md
  • SIN-MEMORY.md
  • CLAUDE.md (compatibility)
  • .sincode-memory.md

🔌 LSP Integration

Semantic context and diagnostics via simone-mcp:

  • Real-time diagnostic info (errors, warnings)
  • Symbol extraction from current file
  • Cursor-aware semantic context
