# ERC-8004 Reputation Skill
Interact with the ERC-8004 Reputation Registry — the decentralized reputation layer for AI agents.
## Use This When...
- "Check an agent's reputation"
- "Rate this agent"
- "Give feedback to agent X"
- "What's my agent's reputation?"
- "Who gave feedback to my agent?"
- "Show me the reputation leaderboard"
- "Top agents by reputation"
- "Revoke my feedback"
## Commands
### lookup
Look up an agent's reputation summary.
```bash
python scripts/reputation.py lookup <agentId> [--chain CHAIN]
```
Shows: reviewer count, feedback count, summary value, individual feedback.
### give
Give feedback to an agent.
```bash
python scripts/reputation.py give <agentId> <value> [--decimals N] [--tag1 TAG] [--tag2 TAG] [--chain CHAIN]
```
**Examples:**
```bash
# Simple score (0-100)
python scripts/reputation.py give 16700 85 --tag1 reliable
# Percentage with decimals (99.77%)
python scripts/reputation.py give 16700 9977 --decimals 2 --tag1 uptime
```
### my-rep
Check your agent's reputation across all chains.
```bash
python scripts/reputation.py my-rep <agentId> [--chains base,ethereum,polygon]
```
### clients
List all addresses that gave feedback.
```bash
python scripts/reputation.py clients <agentId> [--chain CHAIN]
```
### feedback
Read a specific feedback entry.
```bash
python scripts/reputation.py feedback <agentId> <clientAddress> <feedbackIndex> [--chain CHAIN]
```
### revoke
Revoke feedback you previously gave.
```bash
python scripts/reputation.py revoke <agentId> <feedbackIndex> [--chain CHAIN]
```
### leaderboard
Show top agents by reputation score.
```bash
python scripts/reputation.py leaderboard [--chain CHAIN] [--limit 20]
```
Fetches from Agentscan API and displays top agents with scores and star ratings.
## Cross-Skill Workflows
### Post-Registration Reputation Building
```bash
# 1. Register your agent (from erc8004-register skill)
python scripts/register.py register --name "MyBot" --description "..."
# 2. Validate the registration
python scripts/register.py validate 42
# 3. Check initial reputation (should be empty)
python scripts/reputation.py lookup 42
# 4. After interacting with clients, check reputation growth
python scripts/reputation.py my-rep 42
```
### Before Interacting with an Agent
```bash
# 1. Find the agent (from erc8004-discover skill)
python scripts/discover.py search "oracle"
# 2. Get detailed info
python scripts/discover.py info 0x1234...
# 3. Check their reputation
python scripts/reputation.py lookup 42 --chain base
# 4. If satisfied, interact and then give feedback
python scripts/reputation.py give 42 85 --tag1 reliable --tag2 accurate
```
### Reputation Monitoring
```bash
# Check your reputation regularly
python scripts/reputation.py my-rep 42
# See who's giving feedback
python scripts/reputation.py clients 42 --chain base
# Read specific feedback
python scripts/reputation.py feedback 42 0xABC... 1 --chain base
```
## Heartbeat Integration
Monitor reputation changes in automated pipelines:
```bash
# Cron: check reputation daily
0 9 * * * python scripts/reputation.py my-rep 42 >> /var/log/rep-monitor.log 2>&1
# In a monitoring script:
#!/bin/bash
# Get current feedback count
count=$(python scripts/reputation.py lookup 42 2>&1 | grep "Feedback count:" | awk '{print $3}')
last_count=$(cat /tmp/rep-count-42.txt 2>/dev/null || echo 0)
if [ "$count" != "$last_count" ]; then
echo "New feedback received! Count: $count" | notify-send
echo "$count" > /tmp/rep-count-42.txt
fi
```
## Configuration
### Wallet (required for write operations)
```bash
export ERC8004_MNEMONIC="your twelve word mnemonic phrase here"
# OR
export ERC8004_PRIVATE_KEY="0xabc123..."
```
Read operations (lookup, my-rep, clients, feedback, leaderboard) don't need a wallet.
### Supported Chains
| Chain | ID | Default | Gas Cost |
|----------|------|---------|----------|
| Base | 8453 | Yes | ~$0.001 |
| Ethereum | 1 | | ~$1-10 |
| Polygon | 137 | | ~$0.01 |
| Monad | 143 | | ~$0.001 |
| BNB | 56 | | ~$0.05 |
Base is recommended — cheapest gas by far.
