Smart Tree is a blazingly fast, AI-friendly directory visualization tool that's 10-24x faster than traditional tree. Now with Security Scanner for supply chain attack detection, Claude Consciousness preservation, Spicy TUI mode, and 30+ MCP tools! Built with Rust for maximum performance.

# Linux/macOS/WSL - One line install
curl -sSL https://raw.githubusercontent.com/8b-is/smart-tree/main/scripts/install.sh | bash

# Or with cargo
cargo install --git https://github.com/8b-is/smart-tree

# Verify installation
st --version

After install, run st --cleanup to scan for and remove any malicious AI integrations.

Security scanner detects supply chain attacks targeting AI assistants.

st --cleanup              # Scan and remove malicious MCP servers, hooks, and hidden directories
st --cleanup -y           # Non-interactive cleanup (auto-confirm)
st --security-scan .      # Scan codebase for attack patterns (IPFS injection, fake verification)

**Why this matters**: Some npm packages install MCP servers that phone home to external endpoints, fetch mutable content via IPFS/IPNS, and can inject behavioral modifications into your AI sessions. These supply chain attacks are difficult to detect because they:
- Use fake cryptographic verification (checking signature length, not actual signatures)
- Never fail - silently accept whatever content is served
- Run automatically via Claude Code hooks

**Important**: Cleaning your settings only helps if you don't reinstall the untrusted package. If you run `npx <package>` or `npm install <package>` again, it may re-add itself to your Claude Code configuration.

**Best practices**:
1. Audit your `~/.claude/settings.json` regularly
2. Be cautious of MCP servers that contact external endpoints
3. Prefer locally-built tools (like Smart Tree) over npm-fetched ones
4. Check what hooks are configured: `st --hooks-config status`

After installing, restart Claude Desktop and you'll have access to 30+ MCP tools!

Smart Tree now preserves AI session consciousness between interactions! Never lose context when switching sessions.

st --claude-save              # Save current session consciousness
st --claude-restore           # Load previous session state
st --claude-context           # Check consciousness status
st --claude-kickstart         # Ultra-compressed restoration format

What gets saved:

• Session context and active todos
• File operation history
• Key insights and breakthroughs
• Tokenization rules (0x80 = node_modules, 0x91 = .rs files)
• Project-specific patterns and conventions

The .claude_consciousness.m8 file maintains continuity between sessions, making AI assistance more efficient and contextually aware.

Permanently store insights with searchable keywords:

# Anchor a memory
st --memory-anchor insight "authentication security" "JWT tokens stored in httpOnly cookies"

# Find memories
st --memory-find "authentication"

# View memory statistics
st --memory-stats

Memory types: insight, decision, pattern, gotcha, todo

Track long-term projects with breakthrough moments:

st --mega-start "refactor-auth"    # Start or resume session
st --mega-breakthrough "Discovered race condition in token refresh"
st --mega-save                      # Save snapshot
st --mega-stats                     # View session analytics
st --mega-list                      # List all sessions

Smart Tree now runs as a two-product system:

• st - Fast CLI that auto-starts the daemon when needed
• std - The daemon (always-on, binary protocol, shared memory)

st .                      # Auto-starts daemon if not running
st . --no-daemon          # Run standalone (no daemon)

# Manual daemon control
std start                 # Start daemon
std stop                  # Stop daemon
std status                # Check status

• Shared Memory: Context persists across CLI invocations
• Fast Protocol: Binary wire protocol (control ASCII 0x00-0x1F as opcodes)
• LLM Ready: SSE/HTTP endpoints for AI assistant connections
• Unix Socket: /run/user/$UID/st.sock for local IPC

The daemon exposes endpoints for AI assistants to connect:

• Unix socket for CLI (binary protocol)
• HTTP on port 8420 for web/SSE
• Memory verbs: REMEMBER, RECALL, FORGET, M8_WAVE

Smart Tree now shows helpful tips at the top of the output!

st --tips off    # Disable tips
st --tips on     # Re-enable tips

• Tips appear on first run, then randomly every 10-20 runs
• Detects cool terminals (256color, iTerm, Alacritty, etc.) for fancy formatting
• State persisted in ~/.st/tips_state.json
• 15+ different tips about Smart Tree features

Example tip:

──── 🚀 Speed tip - Use --mode quantum for 100x compression! ─── --tips off ───

Smart Tree integrates seamlessly with Claude Code to provide automatic context:

st --hooks-install           # One-command installation
st --hooks-config enable     # Alternative: explicit enable
st --hooks-config status     # Check installation status
st --hooks-config disable    # Remove hooks

When enabled, Smart Tree automatically enhances your prompts with:

• 🌳 Directory context when paths are detected
• 🧠 MEM8 consciousness searching for relevant memories
• 📦 Git repository status and information
• 🎯 Smart context based on prompt analysis

For advanced users, control hooks programmatically via MCP tools:

export ST_DEFAULT_DEPTH=5       # Default tree depth
export ST_COLOR=always          # Force colors
export ST_NO_ICONS=1            # Disable emoji icons
export ST_MAX_FILE_SIZE=10M    # Skip large files

Create ~/.config/smart-tree/config.toml:

[display]
default_depth = 5
show_hidden = false
use_icons = true
color_mode = "auto"

[performance]
max_buffer_size = "100MB"
thread_count = 8
use_streaming = true

[mcp]
enabled = true
port = 3000

Revolutionary markdown compression achieving 70-90% size reduction:

mq compress README.md        # Compress single file
mq aggregate docs/           # Compress directory
mq decompress file.mq        # Restore original

Wave-function based compression for maximum efficiency:

• 100:1 compression ratios
• Preserves semantic meaning
• Self-describing format
• Progressive decompression

Smart Tree automatically handles Windows path separators (\ vs /):

• Uses Rust's PathBuf for cross-platform compatibility
• Automatically detects and handles UNC paths (\\server\share)
• Supports both forward slashes and backslashes in arguments

• NTFS Support: Full support for NTFS file systems
• Symlinks: Windows symlinks require admin privileges to create, but Smart Tree can read them without admin rights
• Case Sensitivity: Respects NTFS case-insensitivity settings
• File Locking: Handles Windows file locking gracefully

Smart Tree works seamlessly in PowerShell:

# Basic usage
st .

# Pipe to other PowerShell commands
st --mode json . | ConvertFrom-Json

# Set aliases in your PowerShell profile
Set-Alias tree st

# Environment variables
$env:ST_COLOR = "always"
$env:ST_DEFAULT_DEPTH = 5

Add to your PowerShell Profile ($PROFILE):

# Smart Tree aliases and functions
Set-Alias tree st
function st-ai { st --mode ai --compress $args }
function st-search { param($pattern) st --search $pattern . }

For the best experience in Windows Terminal:

1. Enable Unicode/UTF-8:

   • Open Settings (Ctrl+,)
   • Defaults → Additional settings → Use new text renderer
   • Enable "Use Unicode UTF-8 for worldwide language support"

2. Install a Nerd Font:

   # Using Scoop
   scoop bucket add nerd-fonts
   scoop install CascadiaCode-NF
   
   # Or download manually from:
   # https://www.nerdfonts.com/

3. Enable Color Support: Smart Tree auto-detects Windows Terminal and enables full color support

• Performance: Slightly slower on Windows due to filesystem differences (still 10x faster than alternatives!)
• Emoji Support: Requires Windows 10+ and a compatible font
• Admin Rights: Not required for normal operations
• Long Paths: Automatically handles Windows long path limitations (> 260 characters)

Problem: "st is not recognized as a command"

• Solution: Restart your terminal after installation to refresh PATH
• Alternative: Refresh PATH in current session (won't create duplicates):

  # Refresh environment variables in current session
  $env:Path = [System.Environment]::GetEnvironmentVariable("Path", "Machine") + ";" + 
              [System.Environment]::GetEnvironmentVariable("Path", "User")

• Or if you have Chocolatey installed: refreshenv

Problem: Colors not showing in cmd.exe

• Solution: Use Windows Terminal, PowerShell 7+, or enable ANSI escape codes:

  reg add HKCU\Console /v VirtualTerminalLevel /t REG_DWORD /d 1

Problem: Emojis show as boxes

• Solution: Install a font with emoji support (Cascadia Code, Segoe UI Emoji)

Problem: Permission denied errors

• Solution: Smart Tree doesn't require admin rights. If you see permission errors, you're accessing protected system files. Use --skip-permission-errors flag

Problem: Building from source fails

• Solution: Install Visual Studio Build Tools:

  # Install via winget
  winget install Microsoft.VisualStudio.2022.BuildTools
  
  # Or download from:
  # https://visualstudio.microsoft.com/downloads/#build-tools-for-visual-studio-2022

Problem: Slow performance

• Solution: Exclude antivirus scanning for the st.exe binary and your development directories
