You'll Need:
- ✅ Windows 10/11 - That's it!
- ✅ Anthropic Claude Subscription (Pro or Team plan required)
What Gets Installed Automatically:
- ✅ WSL with Ubuntu - Windows installs this for you (built-in feature)
- ✅ Node.js - Downloaded from nodejs.org
- ✅ Claude Code CLI - Via npm
All installations ask for your permission with Y/N prompts!
IMPORTANT: Keep a Clean Template Copy!
-
One-time setup - Get your template:
- Download/clone from https://github.com/stefans71/Persistant_Claude
- Save it somewhere safe (e.g.,
C:\Templates\Claude_Template) - NEVER use this template folder for actual projects!
- This is your "master copy" to reuse
-
For EACH new project:
- Copy your clean template folder
- Paste it into your development directory
- Rename it to your project name
- Run
claude-launcher.batinside the renamed folder
-
Why this matters:
- Each project needs a fresh start
- Copying from an existing project would include all that project's files
- Claude would get confused about which project it's working on
- Always copy from your clean template, never from another project
Example Workflow:
INITIAL SETUP (do once):
1. Download from GitHub → Save as "Claude_Template"
2. Keep this template folder clean (never work in it)
CREATING NEW PROJECTS (repeat for each project):
1. Copy "Claude_Template" folder
2. Paste into your dev folder
3. Rename to "Website_Redesign"
4. Run claude-launcher.bat inside "Website_Redesign"
5. Claude opens with isolated context for your website
Next project? Go back to step 1 - copy the clean template again!
That's it! Each copy becomes a new, isolated project with its own persistent Claude session.
To resume work on any project:
- Navigate to that project's folder
- Run
claude-launcher.batagain - Claude automatically resumes your conversation exactly where you left off
Example:
Working on "Website_Redesign" project:
1. Open the "Website_Redesign" folder
2. Double-click claude-launcher.bat
3. Claude resumes with all previous context intact
Switch to "Mobile_App" project:
1. Open the "Mobile_App" folder
2. Double-click claude-launcher.bat
3. Claude switches context to Mobile_App conversation
Key Points:
- Each project folder maintains its own conversation
- Run the launcher to resume - no special commands needed
- You can switch between projects anytime
- Conversations persist even after restarting your computer
- Claude remembers everything from your last session

The EASIEST way to get started with Claude Code on Windows!
This simple batch file handles EVERYTHING:
- ✅ Installs WSL & Ubuntu - Windows' built-in Linux feature (no manual downloads!)
- ✅ Installs Node.js - Required for Claude Code
- ✅ Installs Claude Code CLI - Anthropic's AI coding assistant
- ✅ Sets up conversation persistence - Never lose your work
Perfect for beginners: Just run one file, answer Y/N prompts, done! Perfect for pros: Skip the tedious setup, get coding immediately!
Your conversations persist across sessions - pick up exactly where you left off, even days later!
- TRUE Conversation Persistence: Uses tmux to maintain conversations across sessions
- Resume Mid-Sentence: Pick up exactly where you left off, even after days
- Context Preservation: Includes commands to save context before Claude's memory compacts
- Creates CLAUDE.md files: Permanent context file that survives memory limits
- One-File Solution: Just run claude-launcher.bat
- Fully Automated: Installs everything needed automatically
- Project Isolation: Each project has its own tmux session with separate conversation history
I had Claude Code build this so I don't have to worry about Claude losing context for each of my projects. I hope it helps others with this same issue!
This template contains a batch file that:
- Creates text files (CLAUDE.md and claude.config) in your project
- Launches WSL Ubuntu with tmux for session persistence
- Runs Claude Code CLI with --resume flag to continue previous conversations
Required installations (with your approval):
- WSL Ubuntu (for tmux persistence) - without this, no conversation persistence
- Node.js from nodejs.org (for npm) - without this, can't install Claude
- Claude Code CLI via npm - without this, nothing works
The script asks for permission before each installation via Y/N prompts.
All activities are transparent and visible in the batch file code. No hidden operations or data collection.

Note: If Claude doesn't start automatically, type claude in the terminal
Step 1: Enter Plan Mode to define your project
- Press
Shift+Tabto enter plan mode - Discuss your project idea with Claude
- Work out the details together:
What kind of project do I want to build?
What technologies should I use?
What's the best structure?
What conventions should we follow?
Step 2: Save the plan to CLAUDE.md After planning, tell Claude:
We've finished planning. Please update CLAUDE.md with:
- The project purpose we discussed
- The tech stack we decided on
- The project structure we planned
- Any conventions and standards we agreed on
- Current status and next steps
Exit plan mode and implement these updates to CLAUDE.md
Step 3: Have Claude read the context
Read CLAUDE.md to confirm you have the project context
Now Claude knows your project and will maintain this context!
CLAUDE.md - Your Project's Memory Bank
- Auto-generated with basic project info (name, path)
- YOU ADD: Project details, tech stack, conventions, goals
- PURPOSE: Permanent reference that survives context compaction
- WHEN TO UPDATE: Whenever project scope or approach changes
claude.config - System Configuration
- Auto-generated settings file
- Documents project isolation and paths
- DON'T EDIT - it's for system reference only
- Shows Claude's working directory boundaries
- Run launcher → Claude resumes conversation via tmux
- Continue working → Picks up exactly where you left off
- See percentage indicator? → Run context preservation prompt
- Major changes? → Update CLAUDE.md with new information
Shift+Tab- Enter/exit plan mode (planning before coding)Ctrl+C- Cancel current operationCtrl+D- Exit Claude CLICtrl+L- Clear screenCtrl+B, then D- Detach tmux (keep session running)Up/Down arrows- Navigate command historyTab- Auto-complete file paths
- When to use: Before starting work, when designing features
- What it does: Claude thinks through problems without executing
- Exit plan mode: Shift+Tab again or follow Claude's prompts
Ctrl+B, D- Detach session (keeps running)Ctrl+B, [- Scroll mode (use arrows/PageUp/PageDown)q- Exit scroll modeCtrl+B, ?- Show all tmux shortcuts
Claude Code CLI shows a percentage indicator when context starts filling up:
- Appears around 75-80% full (shows remaining capacity)
- Located in the CLI interface during your session
- When you see "25%" or lower = TIME TO SAVE YOUR CONTEXT!
Just copy and paste this prompt into Claude - it will automatically save everything to CLAUDE.md:
The context indicator is showing [X]% remaining. Create a comprehensive summary NOW:
1. List ALL files we've created or modified with their exact paths and purposes
2. Document ALL solutions we've implemented (working and failed attempts)
3. Record ALL key decisions and technical choices with reasoning
4. Note ALL current bugs, issues, and their status
5. Include ALL important code patterns, approaches, and conventions we're following
6. Save ALL working commands, especially complex ones
7. Document exactly where we are in the project and what's next
8. Include any "gotchas" or things to remember
Format as:
## Context Checkpoint - [use bash: date '+%Y-%m-%d %H:%M:%S']
### Files Modified:
[List each file and what we changed]
### Solutions That Worked:
[What we successfully implemented]
### Failed Attempts (DON'T REPEAT THESE):
[What didn't work and why]
### Key Decisions:
[Technical choices and reasoning]
### Current Issues/Bugs:
[What still needs fixing]
### Working Commands:
[Commands that successfully ran]
### Project State:
[Where we are now and what's working]
### Important Notes:
[Anything special to remember]
Now use the Edit tool to append this entire summary to CLAUDE.md with proper formatting. This preserves our work permanently and automatically.
- Claude analyzes the entire conversation
- Creates a comprehensive summary
- Automatically saves it to CLAUDE.md (no manual work!)
- Your context is preserved forever
That's it! One paste, Claude does everything else.
- No indicator: Plenty of context space
- 75-80%: Indicator appears, start thinking about summary
- 25% or less: SAVE IMMEDIATELY using prompt above
- 10%: Critical - save and consider restarting session
- After saving: Continue working, context is preserved in CLAUDE.md
- Context Management:
- Watch for the percentage indicator in Claude CLI
- Save context at 25% to avoid losing work
- After saving, you can continue OR restart fresh with preserved context
- Tmux Session Controls:
- Detach (keep running):
Ctrl+B, thenD - List sessions:
tmux list-sessions(in WSL) - Kill session:
tmux kill-session -t claude-[project-name](in WSL)
- Detach (keep running):
- Edit CLAUDE.md to add project-specific notes (supplementary context)
- TRUE persistence: Your actual conversation history is maintained by tmux
- Conversations persist through system restarts (tmux + Claude's --resume flag)
- Each project has its own isolated tmux session
- Multiple projects can run simultaneously without interference
- No API keys needed - uses your Claude Pro subscription
- ✅ RESTORED: TRUE conversation persistence via tmux

🔍 OPTIONAL SECURITY VERIFICATION
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Last developer verification: August 15, 2025
Status: Clean - No issues found
For Extra Peace of Mind:
If you'd like to verify the code yourself (it's just one simple batch file!), you can:
- Open this repository in Claude Code
- Copy and paste the comprehensive security audit prompt below
- Claude will thoroughly check all files for any security issues
- Only proceed if you receive a clear "SAFE" verdict
📋 Security Audit Prompt
Copy and paste this entire prompt into Claude Code:
Please perform a static code review of the Persistant_Claude repository (https://github.com/stefans71/Persistant_Claude).
**IMPORTANT LIMITATIONS:** This is a static analysis only. I cannot:
- Execute code to detect runtime behaviors
- Guarantee complete safety
- Replace proper security tools
If using Claude Code: Use available tools (Read, Grep, LS) to examine files.
If using Claude.ai: Review visible source code only.
For complete security, also use proper tools like antivirus scanners, sandboxes, and test in isolated environments.
## SYSTEM SECURITY CHECKS:
1. Registry modifications beyond documented WSL installation
2. Creation of new user accounts or modification of existing ones
3. Scheduled tasks, startup items, or persistence mechanisms
4. Privilege escalation attempts or UAC bypasses
5. Modifications to system files, hosts file, or PATH environment
6. Attempts to disable Windows Defender, antivirus, or firewall
7. PowerShell execution policy changes
## NETWORK & DATA SECURITY:
1. Unauthorized network connections or data exfiltration
2. DNS hijacking or proxy configuration changes
3. Firewall rule modifications
4. Hidden downloads from non-official sources
5. Curl/wget/Invoke-WebRequest to suspicious domains
6. Reverse shells or remote access tools
7. Data collection or telemetry not disclosed
## FILE ANALYSIS - Check ALL files, especially:
- *.bat, *.cmd, *.ps1, *.sh, *.bash files
- Hidden files (starting with .)
- Any embedded or encoded content
## MALICIOUS CODE PATTERNS TO DETECT WITH EXAMPLES:
### 1. EXECUTABLE FILES & BINARIES:
- Look for: .exe, .dll, .com, .scr, .msi, .jar files
- Double extensions: .txt.exe, .pdf.exe, .bat.exe
- Base64 starting with "TVqQAAMAAAA" (MZ header)
- Files with MZ/PE headers regardless of extension
### 2. DANGEROUS JAVASCRIPT:
- javascript:eval() or javascript:alert()
- data:text/html,<script>
- document.write(unescape())
- new Function() with obfuscated strings
- String.fromCharCode() building code
### 3. POWERSHELL ATTACK PATTERNS:
- IEX (New-Object Net.WebClient).DownloadString
- powershell -enc [base64]
- powershell -NoP -NonI -W Hidden -Exec Bypass
- [System.Convert]::FromBase64String
- -ExecutionPolicy Bypass or Unrestricted
### 4. URL THREATS:
- URL shorteners: bit.ly, tinyurl.com, goo.gl
- JavaScript protocols: javascript:, data:, vbscript:
- Direct IP addresses: http://192.168.x.x or http://[IP]
- Typosquatted domains: mircosoft.com, goggle.com
- Suspicious TLDs: .tk, .ml, .ga
### 5. DATA EXFILTRATION:
- curl -X POST --data @sensitive_file
- Invoke-RestMethod -Uri -Method Post -Body
- certutil -urlcache -split -f http://
- bitsadmin /transfer
- DNS tunneling via nslookup or dig
### 6. PERSISTENCE MECHANISMS:
- schtasks /create /tn
- reg add HKLM\Software\Microsoft\Windows\CurrentVersion\Run
- echo malicious >> ~/.bashrc or ~/.profile
- crontab modifications
- WMI Event Subscriptions
### 7. OBFUSCATION TECHNIQUES:
- Variable concatenation: $a='Inv';$b='oke'
- Hex encoding: \x70\x6f\x77\x65\x72
- Unicode escapes: \u0070\u006f\u0077
- Base64 in variables: $code=[System.Text.Encoding]
- Character arrays: [char[]](104,101,108,108,111)
## SPECIFIC FILE VERIFICATION:
1. claude-launcher.bat:
- Creates CLAUDE.md context file
- Creates claude.config settings file
- Launches Claude Code CLI
- Optionally installs Node.js/Claude if needed
2. All .sh scripts:
- Verify no access outside project directory
- Check for hidden background processes (&, nohup, disown)
- Look for suspicious environment modifications
3. Template files:
- Ensure no pre-configured malicious content
- Verify no hidden execution triggers
## ADDITIONAL SECURITY CHECKS:
### 8. PATH TRAVERSAL & FILE ACCESS:
- ../../../Windows/System32
- ..\..\..\..\etc\passwd
- %USERPROFILE%\..\..\..\
- Symbolic links: mklink /D link ..\..\
- Access to: %APPDATA%, %LOCALAPPDATA%, %TEMP% for stealing
### 9. ANTI-ANALYSIS & EVASION:
- Start-Sleep -Seconds 600 (long delays)
- if ($env:COMPUTERNAME -eq "SANDBOX")
- Get-WmiObject Win32_ComputerSystem (VM detection)
- Test-Path "C:\Program Files\VMware"
- Checking for debuggers or analysis tools
### 10. SUPPLY CHAIN ATTACKS:
- Typosquatted packages: "expres" instead of "express"
- Suspicious registries: "registry": "http://evil.com"
- Latest versions without pinning: "package": "latest"
- Unknown or new npm accounts as publishers
### 11. CREDENTIAL & SECRET THEFT:
- Get-Credential or Read-Host -AsSecureString
- Accessing browser password stores
- Reading .git/config or .env files
- Clipboard monitoring: Get-Clipboard
- Keylogger patterns: [System.Windows.Forms.SendKeys]
### 12. WINDOWS SPECIFIC THREATS:
- Alternate Data Streams: file.txt:hidden.exe
- BITS jobs: Start-BitsTransfer
- COM object abuse: New-Object -ComObject
- DLL hijacking setups
- UAC bypass techniques
## RED FLAGS - IMMEDIATE UNSAFE if found:
- Any .exe, .dll, .scr, .com files in the repository
- Any cryptocurrency addresses (bitcoin:, ethereum:, etc.)
- Direct IP addresses in URLs (http://[numbers])
- Heavy obfuscation or encoding without clear purpose
- Attempts to disable Windows Defender or antivirus
- Commands that encrypt files (especially with .locked extensions)
- Network traffic to non-Microsoft/Ubuntu/NPM domains
- JavaScript protocol URLs (javascript:, data:text/html)
- PowerShell download cradles or encoded commands
- Requests for passwords or credentials
- Modifications to system files or registry
- Long sleep/delay commands (evasion tactic)
## REQUIRED OUTPUT FORMAT:
Provide a clear security summary with visual indicators:
### SECURITY AUDIT SUMMARY:
