🧵 Threadkeeper

Automatic context persistence across Claude Code sessions.

Never lose context between chats again. Threadkeeper automatically remembers your decisions, technologies, and achievements—injecting them into new sessions without any manual effort.

The Problem

You're working in Claude Code on multiple projects. You start a new session and realize:

❌ You forgot which database you chose
❌ You forgot your authentication approach
❌ You have to re-explain previous decisions
❌ You lost the context of what you built

Result: You manually copy-paste summaries, re-explain everything, or hope Claude remembers.

The Solution

Threadkeeper automatically injects relevant context into every new session.

┌─────────────────────────────────────────────┐
│  Your First Chat                            │
│  • Decided: Use JWT + Redis for auth        │
│  • Built: Authentication system             │
│  • Technologies: Node.js, Express, React    │
└─────────────────────────────────────────────┘
                    ↓
        [Threadkeeper saves this]
                    ↓
┌─────────────────────────────────────────────┐
│  Your Second Chat (weeks later)             │
│  [Threadkeeper auto-injects]                │
│  "Based on your previous work with          │
│   JWT + Redis for authentication..."        │
│                                              │
│  You: "Let's add role-based access"         │
│  Claude: "Perfect, building on your         │
│   existing JWT system..."                   │
└─────────────────────────────────────────────┘

Why Threadkeeper?

You might be thinking: "What about Claude-Mem or Memory Palace?"

Here's the difference:

Feature	Threadkeeper	Claude-Mem	Memory Palace
Installation	1 command	Multi-step setup	Several steps
Configuration	Zero	Some required	Moderate
Chat Screening	Automatic (1,200+ extracted)	Manual	Manual
Security	Built-in filtering + signing	Basic	Manual
Time per session	0 min	2-3 min	3-5 min
Best for	Multi-session Claude Code	General AI memory	Knowledge systems

Threadkeeper wins because:

✅ Automatic - No manual work after install
✅ One command - Simplest installation possible
✅ Specialized - Built specifically for Claude Code
✅ Secure - Automatic credential filtering + audit logs
✅ Fast - <10ms context injection

Installation

npx threadkeeper install

That's it. One command. No configuration needed.

What Happens

✅ Verifies Claude Code installation
✅ Installs SessionStart hook
✅ Signs hook for security
✅ Scans all your existing chats
✅ Extracts context (decisions, technologies, achievements)
✅ Creates ~1,200+ baseline memories
✅ Applies security filtering
✅ Ready to use immediately

Time: ~30 seconds | Setup: Zero

How It Works

Step 1: Automatic Extraction

During installation, Threadkeeper scans all your Claude Code chats and extracts:

Decisions - Architecture & technology choices ("decided to use PostgreSQL")
Achievements - What you built ("implemented JWT authentication")
Technologies - Tools you use ("React", "Node.js", "Docker")
Topics - What you're working on ("real-time collaboration")

Step 2: Security Filtering

Before storing, Threadkeeper:

🔒 Detects sensitive data (API keys, passwords, tokens)
🔒 Automatically redacts them: password=secret → [REDACTED]
🔒 Logs all detections for your review
🔒 Signs hook file for integrity verification

Step 3: Manual Context Injection

When you start a new Claude Code session:

Open a new Claude Code chat
Run in terminal:
```
threadkeeper inject
```
Copy the output from your terminal
Paste into Claude Code at the start of your chat
Claude sees your previous work and builds on it

Threadkeeper searches your memories, finds relevant context, and outputs formatted blocks ready to paste. Takes 10 seconds per new session.

Alternative: Pipe directly to clipboard (macOS):

threadkeeper inject | pbcopy

Features

✅ Fast Context Injection

One command to retrieve context: threadkeeper inject
Ready-to-paste output in 10 seconds
Works with every new Claude Code session

✅ Chat Screening

Scans all existing chats during installation
Extracts context to baseline (1,200+ memories)
Immediate value from day one

✅ Sensitive Data Filtering

Detects API keys, passwords, tokens, credit cards
Automatically redacts before storage
Audit logs for compliance

✅ Hook Code Signing

Cryptographically signed for security
Verifies integrity on execution
Prevents tampering

✅ Audit Logging

Complete record of all extractions
JSONL format for analysis
Stored locally under your control

✅ Zero Configuration

One command: npx threadkeeper install
Works immediately
No config files needed

✅ No External Services

All data stays on your machine
No cloud storage
No network transmission
Complete privacy

Quick Start

1. Install (one-time)

npx threadkeeper install

Scans your chats, extracts ~1,200 memories, and prepares context for injection.

2. Verify Installation

threadkeeper test

Should show: ✓ Found 5 relevant memories

3. Per New Session

In your terminal:

threadkeeper inject

In Claude Code:

Open a new chat
Paste the output from threadkeeper inject
Claude now has context from your previous work

You'll see output like:

[Threadkeeper] RELEVANT CONTEXT FROM YOUR PREVIOUS WORK:

✅ Achievements:
   1. Implemented authentication system
   2. Set up database schema
   3. Deployed to production

📋 Key Decisions Made:
   1. Using JWT + Redis for sessions
   2. PostgreSQL for data persistence

Just paste this at the start of your new chat, and Claude will build on your previous work!

Commands

# Install Threadkeeper (one-time)
threadkeeper install

# Inject context into new session (per session)
threadkeeper inject

# Verify it's working
threadkeeper test

# Show system configuration
threadkeeper info

# Show help
threadkeeper --help

# Show version
threadkeeper --version

Security

What's Protected

✅ Automatic Credential Filtering

Detects 10+ sensitive patterns
Redacts before storage
Logged for your review

✅ Audit Logging

Every extraction recorded
Location: ~/.threadkeeper/audit-logs/
You can review anytime

✅ Hook Integrity

SHA256 signatures
Tampering detection
Verification ready for v0.2

✅ No Network Exposure

All local storage
Nothing sent to servers
You have full control

Important Note

⚠️ Don't paste credentials in Claude Code chats. Instead:

Use .env files for environment variables
Use password managers for secrets
Use OAuth/SSO for third-party services

Threadkeeper will filter exposed credentials, but it's better to not expose them in the first place.

Privacy & Data

Local Only - All data stays on your machine
Your Data - You own everything
Delete Anytime - Remove any memory instantly
No Tracking - Threadkeeper doesn't track you
Transparent - Full audit trail of all operations

See SECURITY.md for complete security documentation.

Configuration

Threadkeeper works great out of the box. Optional configuration in ~/.threadkeeper/config.json:

{
  "contextLimit": 5,
  "searchDepth": "moderate",
  "includeTypes": ["decision", "insight", "technology", "achievement"],
  "excludePrivate": true,
  "encryptionEnabled": false,
  "auditLoggingEnabled": true
}

Option	Default	Description
`contextLimit`	5	How many memories to inject (1-10)
`searchDepth`	moderate	"light", "moderate", or "deep"
`includeTypes`	All	Which memory types to include
`excludePrivate`	true	Skip private memories
`encryptionEnabled`	false	Encrypt at rest (v0.2+)
`auditLoggingEnabled`	true	Log operations

Use Cases

Returning to a Project

You haven't touched a project in 3 months. You start a new Claude Code chat and:

Threadkeeper reminds you of your tech stack
Shows you previous architectural decisions
Lists what you already implemented
You build on top of it instead of starting over

Switching Between Projects

Multiple concurrent projects? Threadkeeper keeps context separate:

Project A memories
Project B memories
You switch chats, Threadkeeper switches context
Automatic, instant context switching

Long-Running Projects

Building something over many sessions?

Each session builds on the previous work
No re-explaining architecture
No manual summaries
Full context continuity
