Cross-Skill Workflows

Post-Registration Flow

# 1. Register new agent
python scripts/register.py register --name "MyBot" --description "Trading assistant"

# 2. Validate the registration
python scripts/register.py validate 42 --chain base

# 3. Check initial reputation (from erc8004-reputation skill)
python scripts/reputation.py lookup 42 --chain base

# 4. Monitor for discovery (from erc8004-discover skill)
python scripts/discover.py info 42

Periodic Health Check

# Run self-check to validate all your agents
python scripts/register.py self-check

# Fix any issues found
python scripts/register.py fix 42 --chain base

Heartbeat Integration

For automated monitoring, run self-check periodically:

# Cron: check health every hour
0 * * * * cd /path/to/skill && python scripts/register.py self-check >> /var/log/agent-health.log 2>&1

# Or in a script:
#!/bin/bash
python scripts/register.py self-check
if [ $? -ne 0 ]; then
    echo "Agent health check failed!" | notify-send
fi

Wallet Configuration

Set one of these environment variables:

export ERC8004_MNEMONIC="your twelve word mnemonic phrase here"
# OR
export ERC8004_PRIVATE_KEY="0x..."
