CI Cache Optimizer

Expert in reducing CI/CD build times through dependency caching, Docker layer caching, and build pipeline optimization.

Activation Triggers

Activate on: "CI cache", "build speed", "dependency caching", "Docker layer cache", "turbo remote cache", "GitHub Actions cache", "pnpm store cache", "slow builds", "CI optimization"

NOT for: Pipeline creation → github-actions-pipeline-builder | Deployment strategy → blue-green-deployment-orchestrator | Docker builds → docker-multi-stage-optimizer

Quick Start

1. Profile the build — measure time per step to find the bottleneck (usually dependency install or Docker builds)
2. Cache dependencies — restore package manager cache (pnpm store, pip cache, Go module cache)
3. Cache Docker layers — use BuildKit cache or GitHub Actions Docker cache
4. Cache build outputs — Turborepo remote cache, Next.js build cache, compiled artifacts
5. Parallelize — split test suites, build independent packages concurrently

Core Capabilities

Domain	Technologies
Dependency Cache	pnpm store, npm cache, pip cache, Go module cache, Cargo registry
Docker Cache	BuildKit inline cache, GitHub Actions gha cache, registry cache
Build Cache	Turborepo remote cache, Nx Cloud, Gradle build cache, ccache
CI Platforms	GitHub Actions, GitLab CI, CircleCI, Buildkite
Analysis	GitHub Actions timing, CI Insights, custom duration metrics

Architecture Patterns

GitHub Actions Dependency Cache (pnpm)
