How does it improve workflow efficiency?

By consolidating checks into a single phase, it prevents mid-process failures that often require manual cleanup, complex rollbacks, or wasted compute time.

What categories of checks does this skill support?

It supports five main categories: Environment (tools/variables), Access (permissions/tokens), State (resource availability), Input (formatting), and Dependencies (upstream services).

What is the 'fail fast' principle in this skill?

The fail-fast principle ensures that errors are identified during an initial validation gate phase before any actual work is performed, preventing operations from failing halfway through and leaving systems in an inconsistent state.

Can I use this for Kubernetes deployments?

Yes, it is highly effective for checking cluster contexts, namespace existence, RBAC permissions, and resource availability before applying YAML configurations.

Deployment & DevOps

Consolidates all pre-execution validation into a structured gate phase to ensure tool, permission, and resource readiness.

About

This skill implements a structured 'check-before-act' pattern for Claude Code, allowing developers to centralize validation logic into a dedicated phase before any deployment or automation task begins. By evaluating environment variables, access permissions, system states, and dependencies upfront, the skill helps Claude identify potential failures early, preventing partial executions and reducing system instability. It is particularly valuable for complex DevOps workflows, database migrations, and CI/CD pipeline management where 'failing fast' saves significant time and compute resources.
