4 reviewsI'm not sure why the Semgrep scan passes but the SARIF upload fails, and I want Semgrep reinstated for frontend, Dockerfiles, and workflows.
I'm not sure how to implement the semgrep-sast-pr-gate blueprint, especially the flow file and description block.
I'm uncertain about adding SAST to the reusable workflow, but it could broaden security coverage.
I think integrating CodeQL, Semgrep, and gitleaks into CI is valuable for comprehensive security checks.
