📦 Ci Pipeline Optimizer — Ci 流水线 优化器

CI 流水线 优化器

Make CI/CD 流水线s faster and cheaper. Analyzes 工作流 files to find 机器人tlenecks, missing 缓存s, serial steps that can 运行 in parallel, unnecessary work, and oversized Docker builds.

Use when: "CI is too slow", "优化 our 流水线", "reduce build time", "CI costs too much", "speed up GitHub Actions", "流水线 taking 20 minutes", or doing CI/CD mAIntenance.

Commands

• analyze — Full 流水线 Analysis

扫描 all CI configuration files and identify optimization opportunities.
