brain-init

The user wants to initialize their Claude Brain sync network.

Parse arguments:

• If arguments contain "--encrypt", enable encryption
• The first non-flag argument is the Git remote URL

Arguments provided: $ARGUMENTS

Steps

1. First, check dependencies by running:

`` "${CLAUDE_PLUGIN_ROOT}/scripts/common.sh" && echo "OK" `` If jq and git are missing, tell the user what to install.

1. Validate the remote URL for security:

``bash source "${CLAUDE_PLUGIN_ROOT}/scripts/common.sh" validate_remote_url "$ARGUMENTS" `` If the URL is detected as pointing to a PUBLIC repository, STOP and warn the user:

• "WARNING: This repository appears to be PUBLIC. Your brain data (memory, skills, settings, and potentially sensitive information) will be visible to anyone."
• "Please use a PRIVATE repository."
• Ask the user if they want to continue anyway.

1. Show the user their current brain inventory by running:

`` bash "${CLAUDE_PLUGIN_ROOT}/scripts/status.sh" ``

1. IMPORTANT: Show the user a security notice before proceeding:

Tell the user:

• "Brain sync will export the following to the Git remote:"
• " - CLAUDE.md, rules, skills, agents (your instructions and workflows)"
• " - Auto memory and agent memory (learned patterns from your sessions)"
• " - Settings (hooks, permissions — NOT env vars)"
• " - MCP server configurations (command/args only — env vars with API keys are STRIPPED)"
• " - Keybindings"
• ""
• "What is NEVER exported: OAuth tokens, API keys in env vars, ~/.claude.json, session transcripts"
• ""
• "Note: Memory files may contain information from your conversations. Review ~/.claude/projects/*/memory/ if concerned."

1. Ask the user to confirm they want to initialize brain sync with the provided remote.

1. Run the initialization sequence:

```bash # Parse arguments for encryption flag ENABLE_ENCRYPTION=false REMOTE_URL="" for arg in $ARGUMENTS; do case "$arg" in --encrypt) ENABLE_ENCRYPTION=true ;; *) if [ -z "$REMOTE_URL" ]; then REMOTE_URL="$arg"; fi ;; esac done

# Create brain repo directory mkdir -p ~/.claude/brain-repo

# Initialize git repo cd ~/.claude/brain-repo git init git remote add origin "$REMOTE_URL" 2>/dev/null || git remote set-url origin "$REMOTE_URL"

# Create directory structure mkdir -p machines consolidated meta

# Initialize meta files echo '{"entries":[]}' > meta/merge-log.json

# Set up encryption if requested if [ "$ENABLE_ENCRYPTION" = "true" ]; then echo "Setting up age encryption..."

# Check if age is installed if ! command -v age-keygen &>/dev/null; then echo "ERROR: age not found. Install it from https://github.com/FiloSottile/age" echo "On macOS: brew install age" echo "On Ubuntu/Debian: apt install age" exit 1 fi

# Generate age keypair source "${CLAUDE_PLUGIN_ROOT}/scripts/common.sh" IDENTITY_FILE="${HOME}/.claude/brain-age-key.txt" RECIPIENTS_FILE="${HOME}/.claude/brain-repo/meta/recipients.txt" generate_age_keypair "$IDENTITY_FILE" "$RECIPIENTS_FILE"

echo "Age encryption configured:" echo " Private key: $IDENTITY_FILE" echo " Public key: $RECIPIENTS_FILE" fi

# Register this machine (with encryption settings) if [ "$ENABLE_ENCRYPTION" = "true" ]; then bash "${CLAUDE_PLUGIN_ROOT}/scripts/register-machine.sh" "$REMOTE_URL" --encrypt else bash "${CLAUDE_PLUGIN_ROOT}/scripts/register-machine.sh" "$REMOTE_URL" fi

# Export initial brain snapshot MACHINE_ID=$(cat ~/.claude/brain-config.json | jq -r '.machine_id') mkdir -p "machines/${MACHINE_ID}" bash "${CLAUDE_PLUGIN_ROOT}/scripts/export.sh" --output "machines/${MACHINE_ID}/brain-snapshot.json"

# Copy as initial consolidated brain cp "machines/${MACHINE_ID}/brain-snapshot.json" consolidated/brain.json

# Commit and push (specific paths, not -A) git add machines/ consolidated/ meta/ git commit -m "Initialize brain: $(hostname)" git branch -M main git push -u origin main ```

1. Confirm success and show the user:
2. Their machine ID and name
3. The remote URL
4. Instructions: "Install claude-brain on your other machines and run: /brain-join $ARGUMENTS"
5. Reminder: "Auto-sync is enabled. Brain syncs silently on every session start/end."

If any step fails, show the error and suggest fixes (e.g., create the remote repo first on GitHub).
