OPERATOR SKILL: This skill executes commands including transaction submission. Requires explicit human invocation.

When to use

When ready to build and submit a transaction
After reviewing guidance from cardano-cli-transactions

Operating rules (must follow)

Confirm network before ANY operation
Show full transaction details before signing
REQUIRE explicit "yes" confirmation before submit
Create tx bundle folder for reproducibility
Verify UTxO changes after submit

Pre-flight checklist

[ ] Network confirmed: ___________
[ ] Sender address verified
[ ] Recipient address verified (check first/last 8 chars)
[ ] Amount confirmed: ___________ lovelace
[ ] Signing key path confirmed
[ ] UTxO inputs selected

Execution workflow

Step 1: Setup tx bundle

TX_DIR="tx-$(date +%Y%m%d-%H%M%S)"
mkdir -p "$TX_DIR" && cd "$TX_DIR"

Step 2: Query UTxOs

cardano-cli conway query utxo \
  --address <sender-addr> \
  --testnet-magic 1 \
  --out-file utxos.json

Step 3: Fetch protocol parameters

cardano-cli conway query protocol-parameters \
  --testnet-magic 1 \
  --out-file pparams.json

Step 4: Build transaction

cardano-cli conway transaction build \
  --testnet-magic 1 \
  --tx-in <utxo>#<index> \
  --tx-out <recipient>+<amount> \
  --change-address <sender> \
  --out-file tx.unsigned

Step 5: Sign (show what's being signed)

echo "=== SIGNING TRANSACTION ==="
echo "Inputs: <utxo>"
echo "Output: <recipient> receives <amount> lovelace"
echo "Change: returns to <sender>"

cardano-cli conway transaction sign \
  --tx-file tx.unsigned \
  --signing-key-file <payment.skey> \
  --testnet-magic 1 \
  --out-file tx.signed

Step 6: Submit (REQUIRES CONFIRMATION)

⚠️  CONFIRM SUBMISSION ⚠️
Network: preprod
Sending: X ADA to addr_test1...
From: addr_test1...

Type 'yes' to submit:

cardano-cli conway transaction submit \
  --testnet-magic 1 \
  --tx-file tx.signed

Step 7: Verify

# Get tx hash
cardano-cli conway transaction txid --tx-file tx.signed

# Query recipient UTxO
cardano-cli conway query utxo \
  --address <recipient> \
  --testnet-magic 1

Safety / key handling

Never submit without explicit user confirmation
For mainnet: require double confirmation
Keep tx bundle for audit trail
Recommend small test tx first on mainnet
