CI/CD Pipelines

Quick Guide: GitHub Actions for CI/CD. Affected detection for monorepo optimization (e.g., Turborepo --affected or --filter=...[origin/main]). Dependency and build output caching for fast CI. Quality gates: lint + type-check + test + build + coverage as required status checks. Multi-environment deployments with build promotion. OIDC authentication for cloud providers. Pin all action and runtime versions.

CRITICAL: Before Using This Skill

All code must follow project conventions in CLAUDE.md (kebab-case, named exports, import ordering, import type, named constants)

(You MUST use affected/changed-package detection for PR builds - NEVER run full test suite on PRs)

(You MUST cache package manager dependencies and build outputs - CI without caching wastes 70% of runtime)

(You MUST pin action versions (actions/checkout@v6, oven-sh/setup-bun@v2, actions/cache@v5) - NEVER use @main or unversioned)

(You MUST implement quality gates (lint + type-check + test + build) as required status checks - block merge on failures)
