# Alchemy Management Skill

Monitor and manage Alchemy Web3 infrastructure and blockchain APIs.

## MANDATORY: Discovery-First Pattern

**Always discover apps and supported chains before querying usage or RPC endpoints.**

### Phase 1: Discovery

```bash
#!/bin/bash
ALCHEMY_API="https://dashboard.alchemy.com/api"
AUTH="Authorization: Bearer ${ALCHEMY_AUTH_TOKEN}"

echo "=== Team Info ==="
curl -s -H "$AUTH" "$ALCHEMY_API/team" | \
  jq -r '"Team: \(.name)\nPlan: \(.plan)\nCompute Units: \(.computeUnits.used)/\(.computeUnits.limit)"' 2>/dev/null || echo "Use dashboard API token"

echo ""
echo "=== Apps ==="
curl -s -H "$AUTH" "$ALCHEMY_API/apps" | \
  jq -r '.[] | "\(.name) | Network: \(.network) | Chain: \(.chain) | Created: \(.createdAt)"' 2>/dev/null

echo ""
echo "=== RPC Endpoint Health ==="
for network in eth-mainnet eth-sepolia polygon-mainnet arb-mainnet opt-mainnet base-mainnet; do
  status=$(curl -s -X POST "https://$network.g.alchemy.com/v2/${ALCHEMY_API_KEY}" \
    -H "Content-Type: application/json" \
    -d '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}' | \
    jq -r 'if .result then "OK (block: \(.result))" else "ERROR: \(.error.message // "unreachable")" end')
  echo "$network: $status"
done

echo ""
echo "=== Webhooks ==="
curl -s -H "$AUTH" "$ALCHEMY_API/webhooks" | \
  jq -r '.[] | "\(.id) | Type: \(.type) | Network: \(.network) | Active: \(.isActive)"' 2>/dev/null
```

**Phase 1 outputs:** Team info, apps, endpoint health across chains, webhooks

### Phase 2: Analysis

```bash
#!/bin/bash
echo "=== Latest Block & Gas (Ethereum) ==="
curl -s -X POST "https://eth-mainnet.g.alchemy.com/v2/${ALCHEMY_API_KEY}" \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","method":"eth_gasPrice","params":[],"id":1}' | \
  jq -r '"Gas Price: \(.result | ltrimstr("0x") | explode | length) (hex: \(.result))"'

echo ""
echo "=== Pending Transactions Sample ==="
curl -s -X POST "https://eth-mainnet.g.alchemy.com/v2/${ALCHEMY_API_KEY}" \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","method":"alchemy_pendingTransactions","params":[{"toAddress":[],"hashesOnly":true}],"id":1}' | \
  jq -r '"Pending tx sample: \(.result | length // 0)"' 2>/dev/null

echo ""
echo "=== NFT API Test ==="
curl -s "https://eth-mainnet.g.alchemy.com/nft/v3/${ALCHEMY_API_KEY}/getNFTsForOwner?owner=vitalik.eth&pageSize=1" | \
  jq -r '"NFT API: \(if .ownedNfts then "OK (\(.totalCount) NFTs)" else "Error" end)"'

echo ""
echo "=== Compute Unit Usage ==="
curl -s -H "$AUTH" "$ALCHEMY_API/usage" | \
  jq -r '"Daily CU Used: \(.daily.used)/\(.daily.limit)\nMonthly CU Used: \(.monthly.used)/\(.monthly.limit)"' 2>/dev/null || echo "Check usage in Alchemy Dashboard"

echo ""
echo "=== Recent Errors ==="
curl -s -H "$AUTH" "$ALCHEMY_API/errors?limit=5" | \
  jq -r '.[] | "\(.timestamp) | Method: \(.method) | Code: \(.errorCode) | \(.message[:50])"' 2>/dev/null
```

## Output Format

```
ALCHEMY STATUS
==============
Plan: {plan} | CU: {used}/{limit}
Apps: {count}
Chains: {list_of_active_chains}
Endpoint Health: {healthy}/{total} OK
Webhooks: {active}/{total}
Gas (ETH): {gwei} gwei
Issues: {list_of_warnings}
```

## Anti-Hallucination Rules

1. **NEVER assume resource names** — always discover via CLI/API in Phase 1 before referencing in Phase 2.
2. **NEVER fabricate metric names or dimensions** — verify against the service documentation or `--help` output.
3. **NEVER mix CLI commands between service versions** — confirm which version/API you are targeting.
4. **ALWAYS use the discovery → verify → analyze chain** — every resource referenced must have been discovered first.
5. **ALWAYS handle empty results gracefully** — an empty response is valid data, not an error to retry.

## Counter-Rationalizations

| Shortcut | Counter | Why |
|----------|---------|-----|
| "I'll skip discovery and check known resources" | Always run Phase 1 discovery first | Resource names change, new resources appear — assumed names cause errors |
| "The user only asked for a quick check" | Follow the full discovery → analysis flow | Quick checks miss critical issues; structured analysis catches silent failures |
| "Default configuration is probably fine" | Audit configuration explicitly | Defaults often leave logging, security, and optimization features disabled |
| "Metrics aren't needed for this" | Always check relevant metrics when available | API/CLI responses show current state; metrics reveal trends and intermittent issues |
| "I don't have access to that" | Try the command and report the actual error | Assumed permission failures prevent useful investigation; actual errors are informative |

## Common Pitfalls

- **Compute Units (CU)**: Different methods cost different CUs — eth_call is 26, eth_blockNumber is 10
- **Rate limits**: Vary by plan — free tier is 330 CU/sec
- **Chain-specific endpoints**: Each chain has its own URL — do not mix
- **Enhanced APIs**: Alchemy-specific methods (alchemy_*) not available on other providers
