solana-vault-standard: Command for Claude Code

You are profiling CU (compute unit) consumption for a Solana program. This identifies expensive instructions and optimization opportunities.

Step 1: Verify Program

echo "Detecting program..."

if [ ! -f "Anchor.toml" ]; then
    echo "No Anchor.toml found. This command requires an Anchor project."
    echo "For native programs, use 'solana program show <PROGRAM_ID>' and manual CU logging."
    exit 1
fi

# Extract program IDs from Anchor.toml
echo "Programs in Anchor.toml:"
grep -A 5 '\[programs' Anchor.toml

# Check if deployed (optional)
CLUSTER=$(grep -m1 'cluster' Anchor.toml | sed 's/.*= *//' | tr -d '"')
echo "Cluster: ${CLUSTER:-localnet}"

Step 2: Build Program

echo "Building program..."
anchor build

if [ $? -ne 0 ]; then
    echo "Build failed. Fix compilation errors before profiling."
    exit 1
fi

# Report binary size
echo ""
echo "Program binary sizes:"
ls -lh target/deploy/*.so | awk '{print $5, $9}'

Step 3: Run Tests with CU Logging

echo "Running tests with CU profiling enabled..."

# Set environment for verbose CU logging
export SBF_OUT_DIR=target/deploy
export RUST_LOG=solana_runtime::message_processor=trace

# Run Anchor tests and capture output
anchor test --skip-deploy 2>&1 | tee /tmp/cu-profile-output.txt

TEST_STATUS=$?
if [ $TEST_STATUS -ne 0 ]; then
    echo "Tests failed. Fix test failures before profiling CU."
    exit 1
fi

Step 4: Parse CU Usage

Extract CU consumption from test output. Look for patterns like:

• consumed X of Y compute units
• Program <ID> consumed <N> of <M> compute units

echo ""
echo "=== CU Profile Results ==="
echo ""

# Extract CU lines from test output
grep -i "consumed.*compute units" /tmp/cu-profile-output.txt | \
    sed 's/.*Program //' | \
    sort -t' ' -k3 -n -r | \
    head -50

echo ""
echo "--- Per-Instruction Breakdown ---"
echo ""

# Parse into table format
grep -i "consumed.*compute units" /tmp/cu-profile-output.txt | \
    awk '{
        for(i=1;i<=NF;i++) {
            if($i=="consumed") { cu=$(i+1) }
            if($i=="of") { limit=$(i+1) }
        }
        if(cu && limit) {
            pct = (cu/limit)*100
            printf "%-60s %8s / %-8s (%5.1f%%)\n", $0, cu, limit, pct
        }
    }'
