The change enhances readability and visual presentation with CSS adjustments, aligning with documentation standards and reducing potential user confusion.

April 2025 performance summary across the codeql-action and vscode-codeql repositories. Delivered robustness improvements, expanded static analysis coverage for GitHub Actions, and enhanced CI/CD telemetry, delivering measurable business value and technical excellence. Key features delivered: - github/codeql-action: CI/CD improvements and observability enhancements, including telemetry for CodeQL analysis, bump of ruby/setup-ruby action, and updated checks/CHANGELOG to reflect bug fixes. - github/vscode-codeql: GitHub Actions Sample Databases Mapping added to the skeleton wizard to provide relevant sample databases for Actions workflows; expanded CodeQL analysis coverage to include .github/workflows and .github/actions directories. Major bugs fixed: - Robust artifact bundling: Ignore missing ENOENT files during debug artifact creation to prevent crashes and improve reliability when expected files are absent (commit a8be43c24e13329b9e2174ec1941e06e03636dcc). Overall impact and accomplishments: - Increased reliability of artifact bundling, reducing crashes in CI artifacts. - Improved observability and performance insights for CodeQL analysis via telemetry enhancements. - Broadened static analysis coverage for GitHub Actions workflows, enhancing security and quality assurance for Action-based repos. - Clearer user value through better sample data mapping and documentation of fixes. Technologies/skills demonstrated: - TypeScript (skeleton-query-wizard.ts), CodeQL configuration (codeql-config.yml), YAML-based CI tooling, and Ruby tooling (setup-ruby) integration. - Telemetry instrumentation and observability practices, along with robust error handling patterns. Commit highlights: - ENOENT fix: a8be43c24e13329b9e2174ec1941e06e03636dcc - CI/CD/telemetry: dd78aab4078b17a672a66d6a80a990beb672ede1, c0cffae5340e8730067141b1b63834e3c3e69bba, 3ca9a8894139ab39e4f3fdd6a5e2d0ca9474e822 - Actions sample DB mapping: 39dc154e9516f8b6951357a48b1bfc9063d5ec9c - Expanded CodeQL coverage: 5262dfd8a1eb6d098646fd756734894fe446338f, 3882e93f672c981d66efc7e8baa5f81ff2a2ce9d
