Berne Campbell enhanced the semgrep/semgrep-rules repository by expanding rule metadata to include Kubernetes and LLM Top 10 references, broadening detection of security misconfigurations beyond the OWASP Top 10. Using Scala and YAML, Berne developed new validation logic to recognize additional category prefixes, supporting more comprehensive static analysis. To improve signal quality, Berne refined the tainted-sql-string rule by introducing an exclusion for exception handling, reducing false positives and increasing rule precision. This work combined rule development, security auditing, and regular expressions to deliver more actionable alerts and maintainable rule governance, demonstrating thoughtful depth in both technical implementation and problem coverage.
