What problem does it solve?

This Skill eliminates the common, costly pitfalls of unmanaged AWS CDK workflows, including inconsistent stack design, skipped deployment reviews, and unsafe infrastructure-as-code practices that lead to failed deployments, permanent data loss, or critical security misconfigurations.

Core Features & Use Cases

• Standardized Project Structure: Enforces the recommended bin/ + lib/ layout with lifecycle-aligned stack separation (network, data, compute, etc.) to limit blast radius and avoid hitting CloudFormation's 500-resource limit.
• Construct & Workflow Best Practices: Guides selection of L1/L2/L3 constructs, proper use of IAM grant methods, and strict adherence to the synth → diff → deploy flow with mandatory security delta review.
• Failure Troubleshooting: Provides actionable steps for common CDK/CloudFormation failures including ROLLBACK_COMPLETE stacks, cross-stack reference deadlocks, and configuration drift.
• Use Case: For a team building a multi-tier AWS application, this Skill ensures stateful database stacks are isolated from churny compute stacks so a routine app redeploy cannot accidentally delete production data, and forces review of IAM changes before any production deployment.

Quick Start

Invoke this Skill when working on CDK code to validate your stack structure, construct choices, and pre-deploy diff before applying changes to AWS.
