What problem does it solve? AI coding agents generate CLI commands that look correct but fail in production due to flag ordering traps, missing safety checks, interactive prompts that hang without a TTY, and silent misconfigurations. This Skill encodes senior-engineer operational knowledge so agents execute CLI tasks safely and correctly. ## Core Features & Use Cases - 23 Expert CLI Guides: Covers AWS, gcloud, Azure, Terraform, Docker, kubectl, Helm, Git, GitHub CLI, jq, curl, SSH, sed, make, npm, pip/uv, psql, redis-cli, Stripe, Sentry, Vercel, Firebase, and flyctl across 9 categories. - Structured Guide Format: Each guide includes Setup & Auth, Core Workflows, Flag Gotchas, Error Patterns, Anti-Patterns, Composability, and Agent Constraints sections with wrong/right command markers. - Token-Efficient Loading: A category sub-index architecture lets the agent load only the single relevant guide (~200-400 lines) instead of the entire library. - Use Case: When an agent needs to sync files to S3, it loads the AWS guide and correctly orders --exclude "*" before --include "*.json", avoiding the silent data-loss bug caused by reversed filter order. ## Quick Start Ask your agent to perform a CLI task such as deploying with Terraform or debugging a Kubernetes pod, and it will load the matching guide from the skills directory before executing commands.
