# Install to pi skills
pi skill add pi-agent-id ~/.pi/agent/skills/pi-agent-id/bin/pi-agent-id

# Or install globally
sudo cp ~/.pi/agent/skills/pi-agent-id/bin/pi-agent-id /usr/local/bin/
```

### Usage Examples

```bash
# Create HD wallet with mnemonic
pi-agent-id create --name mywallet --hd --password "secure-pass"

# Import from private key
pi-agent-id import --name imported --key 0xabc123... --password "pass"

# List all wallets
pi-agent-id list

# Sign a message
pi-agent-id sign --address 0x123... --message "Hello" --password "pass"

# Check balance
pi-agent-id balance --address 0x123... --rpc https://eth.llamarpc.com

# Send transaction
pi-agent-id send --from 0x123... --to 0x456... --amount 1000000000000000000 \
  --rpc https://eth.llamarpc.com --password "pass"

# Export wallet
pi-agent-id export --name mywallet --password "pass" --private-key

# Recover from mnemonic
pi-agent-id recover --mnemonic "word1 word2 ... word12" --name recovered --password "pass"
```

### Security Features

- **Encryption**: AES-256-GCM with PBKDF2 (100,000 iterations)
- **Storage**: Wallet files are encrypted at rest
- **Permissions**: Files created with 0600 permissions (owner-only)
