Run mutation tests on the specified crate (default: ccswarm):
# Install if needed
cargo mutants --version || cargo install cargo-mutants
# List mutants
cargo mutants --list -p $ARGUMENTS | head -50
# Run mutation tests
cargo mutants -p ${1:-ccswarm} --timeout 120 -j 4
# Report results
echo "=== Caught ===" && wc -l mutants.out/caught.txt
echo "=== Missed ===" && cat mutants.out/missed.txt
echo "=== Timeout ===" && wc -l mutants.out/timeout.txt
Focus on missed mutants in business logic - these indicate insufficient test coverage.
