Features

1. File Integrity Monitoring — Detects tampering of system files
2. TOTP Step-Up Auth — Requires OTP for sensitive agent actions

Part 1: File Integrity Monitoring

Requirements

• Go 1.21+ — Install with brew install go
• macOS — Uses launchd for daemon

Quick Setup

# Install via go install
go install github.com/kris-hansen/feelgoodbot/cmd/feelgoodbot@latest

# Initialize baseline snapshot
feelgoodbot init

# Install and start daemon
feelgoodbot daemon install
feelgoodbot daemon start

# Check it's running
feelgoodbot status

Clawdbot Integration (Alerts)

Enable webhooks:

clawdbot config set hooks.enabled true
clawdbot config set hooks.token "$(openssl rand -base64 32)"
clawdbot gateway restart

Configure ~/.config/feelgoodbot/config.yaml:

scan_interval: 5m
alerts:
  clawdbot:
    enabled: true
    webhook: "http://127.0.0.1:18789/hooks/wake"
    secret: "\x3Chooks.token from clawdbot config get hooks.token>"
  local_notification: true

What It Monitors

• System binaries (/usr/bin, /usr/sbin)
• Launch daemons/agents (persistence mechanisms)
• SSH authorized_keys, sudoers, PAM
• Shell configs (.zshrc, .bashrc)
• Browser extensions
• AI agent configs (Claude, Cursor)

Part 2: TOTP Step-Up Authentication

Step-up auth requires the user to enter an OTP code from Google Authenticator before the agent can perform sensitive actions.

Setup (User runs in terminal)

# Initialize TOTP (shows QR code to scan)
feelgoodbot totp init --account "user@feelgoodbot"

# Verify it works
feelgoodbot totp verify

# Check status
feelgoodbot totp status

Configure Protected Actions

# List current protected actions
feelgoodbot totp actions list

# Add actions that require step-up
feelgoodbot totp actions add "send_email"
feelgoodbot totp actions add "payment:*"
feelgoodbot totp actions add "delete:*"
feelgoodbot totp actions add "ssh:*"
feelgoodbot totp actions add "publish:*"
feelgoodbot totp actions add "gateway:*"
feelgoodbot totp actions add "voice_call:*"
feelgoodbot totp actions add "message:external"

# Remove an action
feelgoodbot totp actions remove "send_email"

TOTP Commands

Session Caching

After successful authentication, a session is cached for 15 minutes (configurable). Subsequent actions within this window don't require re-authentication.

Agent Integration (IMPORTANT)

Before performing any sensitive action, the agent MUST check step-up requirements.

Action Mapping

Map your intended actions to step-up patterns:

Step-Up Check Flow

Before executing a sensitive action:

# Check if action requires step-up (non-interactive check)
feelgoodbot totp check \x3Caction>
# Exit code 0 = proceed, Exit code 1 = denied/not authenticated

If session is valid: Command succeeds immediately (exit 0)

If step-up required and no session:

1. Agent sends Telegram message: "🔐 Action \x3Caction> requires step-up. Reply with your OTP code."
2. Wait for user to reply with 6-digit code
3. Validate: feelgoodbot totp verify \x3Ccode>
4. If valid, create session and proceed
5. If invalid, deny action and notify user

Example Agent Flow (Pseudocode)

function performSensitiveAction(action, execute_fn):
    # Check step-up requirement
    result = exec("feelgoodbot totp check " + action)
    
    if result.exit_code == 0:
        # Session valid or action not protected
        execute_fn()
        return success
    
    # Need to prompt user
    send_telegram("🔐 Action '{action}' requires step-up authentication.\
Reply with your OTP code from Google Authenticator.")
    
    code = wait_for_user_reply(timeout=120s)
    
    if code is None:
        send_telegram("⏰ Step-up authentication timed out. Action cancelled.")
        return denied
    
    # Validate the code
    valid = exec("feelgoodbot totp verify " + code)
    
    if valid.exit_code != 0:
        send_telegram("❌ Invalid code. Action cancelled.")
        return denied
    
    # Create session by running check again (it will pass now)
    exec("feelgoodbot totp check " + action)
    
    execute_fn()
    send_telegram("✅ Action completed.")
    return success

Quick Reference for Agent

Check before these actions:

• send_email — Before sending any email
• payment:* — Before any financial transaction
• delete:* — Before deleting files (delete:file, delete:backup, etc.)
• ssh:* — Before SSH connections
• publish:* — Before publishing/deploying
• gateway:* — Before modifying Clawdbot config
• voice_call:* — Before making phone calls
• message:external — Before messaging non-owner contacts
• config:update — Before modifying step-up config

Commands to use:

# Check and prompt (interactive)
feelgoodbot totp check send_email

# Just validate a code
feelgoodbot totp verify 123456

# Check session status
feelgoodbot totp status

File Locations

Troubleshooting

TOTP code always invalid:

• Check system clock is accurate (date)
• Ensure you're using the correct authenticator entry
• Try a backup code

Step-up not prompting:

• Verify action is in protected list: feelgoodbot totp actions list
• Check TOTP is initialized: feelgoodbot totp status

Reset everything:

# Reset TOTP (requires valid code or backup code)
feelgoodbot totp reset

# Or manually remove (loses access without backup codes!)
rm ~/.config/feelgoodbot/totp.json
rm ~/.config/feelgoodbot/totp-session
