Hermes Memory GitHub Sync (macOS)

Automatically backs up ~/.hermes/memories/, ~/.hermes/skills/, and ~/.hermes/config.yaml to a private GitHub repo every 30 minutes via launchd.

Key Pitfalls (Learned from Experience)

• NEVER use git add -A inside ~/.hermes — it will stage 10,000+ files from .venv/ and hermes-agent/
• Always use explicit paths: git add memories/ skills/ config.yaml SOUL.md .gitignore
• The hermes-agent/ subdirectory is a nested git repo — must be in .gitignore
• The .venv/ virtual environment is huge — must be in .gitignore
• GitHub token is already stored in ~/.git-credentials — no need to create a new one

---

Step 1: Extract GitHub Token

TOKEN=$(grep github ~/.git-credentials | sed 's/.*:\(ghp_[^@]*\)@.*/\1/')
echo "Token: ${TOKEN:0:10}..."

Step 2: Create Private GitHub Repo via API

curl -s -X POST \
  -H "Authorization: token $TOKEN" \
  -H "Accept: application/vnd.github.v3+json" \
  https://api.github.com/user/repos \
  -d '{"name":"hermes-memory","private":true,"description":"Hermes Agent memory sync"}' \
  | python3 -c "import sys,json; d=json.load(sys.stdin); print(d.get('clone_url','ERROR:'+str(d.get('message',d))))"

Step 3: Init Git Repo in ~/.hermes

cd ~/.hermes
git init
git config user.name "yourname"
git config user.email "[e-mail]"
git remote add origin "https://USERNAME:${TOKEN}@github.com/USERNAME/hermes-memory.git"

Step 4: Create .gitignore

Write to ~/.hermes/.gitignore:

# Large directories — DO NOT sync
.venv/
hermes-agent/
sessions/
logs/
cron/
plugins/
__pycache__/

# Temp / sensitive files
*.lock
*.log
*.db
*.db-shm
*.db-wal
.env
auth.json
.DS_Store
.update_check
.hermes_history
.skills_prompt_snapshot.json

Step 5: First Commit & Push

cd ~/.hermes
# IMPORTANT: use explicit paths, not git add -A
git add .gitignore memories/ skills/ config.yaml SOUL.md
git status --short | wc -l   # should be ~400-500 files, not 10000+
git commit -m "init: sync memories, skills and config"
git branch -M main
git push -u origin main

Step 6: Create Sync Script

Write to ~/.hermes/hermes-sync.sh:

#!/bin/bash
set -euo pipefail

HERMES_DIR="$HOME/.hermes"
LOG_FILE="$HERMES_DIR/logs/hermes-sync.log"
DATE=$(date '+%Y-%m-%d %H:%M:%S')

mkdir -p "$HERMES_DIR/logs"
cd "$HERMES_DIR"

if [ ! -d ".git" ]; then
    echo "[$DATE] ERROR: not a git repo" >> "$LOG_FILE"
    exit 1
fi

# Stage only the important files
git add memories/ skills/ config.yaml SOUL.md .gitignore 2>/dev/null || true

# Skip if nothing changed
if git diff --cached --quiet; then
    echo "[$DATE] 没有变化，跳过提交" >> "$LOG_FILE"
    exit 0
fi

git commit -m "sync: auto backup at $DATE" >> "$LOG_FILE" 2>&1

if git push origin main >> "$LOG_FILE" 2>&1; then
    echo "[$DATE] 推送成功" >> "$LOG_FILE"
else
    echo "[] 推送失败（网络问题？），下次再试" >> 
     0



 -500  >  &&   

chmod +x ~/.hermes/hermes-sync.sh

Step 7: Create launchd Plist

Write to ~/Library/LaunchAgents/com.USERNAME.hermes-sync.plist:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN"
  "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>Label</key>
    <string>com.USERNAME.hermes-sync</string>

    <key>ProgramArguments</key>
    <array>
        <string>/bin/bash</string>
        <string>/Users/USERNAME/.hermes/hermes-sync.sh</string>
    </array>

    <!-- Every 30 minutes -->
    <key>StartInterval</key>
    <integer>1800</integer>

    <!-- Run once immediately on load -->
    <key>RunAtLoad</key>
    <true/>

    <!-- PATH is required or git won't be found -->
    <key>EnvironmentVariables</>
    
        PATH
        /usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/homebrew/bin
        HOME
        /Users/USERNAME
    

    StandardOutPath
    /Users/USERNAME/.hermes/logs/hermes-sync-launchd.log
    StandardErrorPath
    /Users/USERNAME/.hermes/logs/hermes-sync-launchd.log

    ThrottleInterval
    60

Step 8: Load & Verify

launchctl load ~/Library/LaunchAgents/com.USERNAME.hermes-sync.plist

# Check it's running (should show com.USERNAME.hermes-sync)
launchctl list | grep hermes

# Wait a few seconds, check the log
sleep 5 && cat ~/.hermes/logs/hermes-sync.log

Expected output: [2026-04-10 17:21:05] 没有变化，跳过提交 (or a push success message)

---

Management Commands

# View sync log
cat ~/.hermes/logs/hermes-sync.log

# Manually trigger sync now
~/.hermes/hermes-sync.sh

# Stop the service
launchctl unload ~/Library/LaunchAgents/com.USERNAME.hermes-sync.plist

# Reload after editing plist
launchctl unload ~/Library/LaunchAgents/com.USERNAME.hermes-sync.plist
launchctl load ~/Library/LaunchAgents/com.USERNAME.hermes-sync.plist

# Check what's tracked in git
cd ~/.hermes && git status --short

Notes

• The launchd service survives reboots automatically (it's in LaunchAgents/, not LaunchDaemons/)
• If git push fails (no network), the script exits cleanly and retries next cycle
• Token is embedded in the remote URL — if token rotates, update with:

  cd ~/.hermes && git remote set-url origin "https://USERNAME:[e-mail]/USERNAME/hermes-memory.git"
  

• To sync a second Mac: git clone https://USERNAME:[e-mail]/USERNAME/hermes-memory.git ~/.hermes then set up the same launchd service
