Cross-Skill Workflows

Pre-Registration Research

# 1. Check what agents already exist in your space
python scripts/discover.py search "trading bot"

# 2. See top competitors
python scripts/discover.py top --chain base --limit 10

# 3. Register your agent (from erc8004-register skill)
python scripts/register.py register --name "MyTradingBot" --description "..."

# 4. Validate registration
python scripts/register.py validate 42

Due Diligence Before Interacting

# 1. Get agent details
python scripts/discover.py info 0x1234...

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

# 3. Decide whether to interact

Competitor Monitoring

# 1. Find competitors
python scripts/discover.py search "security audit"

# 2. Monitor a specific competitor
python scripts/discover.py monitor "CompetitorAgent"

# 3. Check their reputation changes
python scripts/reputation.py lookup 123 --chain base

Heartbeat Integration

Monitor agents for changes in automated pipelines:

# Cron: check if agent changed every 15 minutes
*/15 * * * * python scripts/discover.py monitor 42 >> /var/log/agent-monitor.log 2>&1

# In a monitoring script:
#!/bin/bash
output=$(python scripts/discover.py monitor 42 2>&1)
if echo "$output" | grep -q "CHANGES DETECTED"; then
    echo "Agent 42 metadata changed!" | slack-notify
fi
