# cardano-cli-plutus-scripts-operator
> **OPERATOR SKILL**: Executes Plutus script transactions. Requires explicit human invocation due to collateral risk.
## When to use
- When ready to spend from a script address
- After reviewing guidance from `cardano-cli-plutus-scripts`
## Operating rules (must follow)
- **ALWAYS verify collateral UTxO is ADA-only**
- Confirm script hash matches expected
- Validate datum/redeemer JSON before use
- **REQUIRE explicit confirmation before submit**
- Test on preprod/preview before mainnet
## Pre-flight checklist
```
[ ] Network: ___________
[ ] Script file (.plutus) verified
[ ] Script hash matches on-chain
[ ] Datum JSON validated
[ ] Redeemer JSON validated
[ ] Collateral UTxO selected (ADA-only!)
[ ] Protocol parameters fresh
```
## Execution workflow
### Step 1: Verify script
```bash
# Get script hash
cardano-cli conway transaction policyid \
--script-file script.plutus
# Derive script address
cardano-cli conway address build \
--payment-script-file script.plutus \
--testnet-magic 1 \
--out-file script.addr
```
### Step 2: Query script UTxO
```bash
cardano-cli conway query utxo \
--address $(cat script.addr) \
--testnet-magic 1
```
### Step 3: Prepare collateral
```bash
# Must be ADA-only UTxO at your payment address
cardano-cli conway query utxo \
--address <payment-addr> \
--testnet-magic 1
# Select one with only ADA (no tokens)
```
### Step 4: Build script spend
```bash
cardano-cli conway transaction build \
--testnet-magic 1 \
--tx-in <script-utxo>#<index> \
--tx-in-script-file script.plutus \
--tx-in-inline-datum-present \
--tx-in-redeemer-file redeemer.json \
--tx-in-collateral <collateral-utxo>#<index> \
--tx-out <recipient>+<amount> \
--change-address <payment-addr> \
--out-file tx.unsigned
```
### Step 5: Sign and submit
```bash
# Sign (collateral signer required)
cardano-cli conway transaction sign \
--tx-file tx.unsigned \
--signing-key-file payment.skey \
--testnet-magic 1 \
--out-file tx.signed
# ⚠️ CONFIRM before submit
echo "=== SCRIPT SPEND CONFIRMATION ==="
echo "Script: $(cat script.addr | head -c 20)..."
echo "Spending UTxO: <script-utxo>"
echo "Collateral: <collateral-utxo>"
echo "Output to: <recipient>"
cardano-cli conway transaction submit \
--testnet-magic 1 \
--tx-file tx.signed
```
## Debugging failed scripts
```bash
# If script fails, check execution units
cardano-cli conway transaction build \
... \
--calculate-plutus-script-cost cost.json
# Review cost.json for budget issues
cat cost.json | jq .
```
## Safety / key handling
- Collateral is at risk if script fails unexpectedly
- Use minimal collateral (1-5 ADA typically sufficient)
- Keep datum/redeemer free of secrets
- Verify script logic on testnet first
