# AWS Billing Intelligence - Printing Press CLI ## Prerequisites: Install the CLI This skill drives the `aws-billing-cli` binary. **You must verify the CLI is installed before invoking any command from this skill.** If it is missing, install it first: 1. Install via the Printing Press installer: ```bash npx -y @mvanhorn/printing-press-library install aws-billing --cli-only ``` 2. Verify: `aws-billing-cli --version` 3. Ensure `$GOPATH/bin` (or `$HOME/go/bin`) is on `$PATH`. If the `npx` install fails (no Node, offline, etc.), fall back to a direct Go install (requires Go 1.26.3 or newer): ```bash go install github.com/mvanhorn/printing-press-library/library/cloud/aws-billing/cmd/aws-billing-cli@latest ``` If `--version` reports "command not found" after install, the install step did not put the binary on `$PATH`. Do not proceed with skill commands until verification succeeds. A self-contained Go binary (native AWS SDK, no aws CLI needed) that pulls your bill, breaks it down per-account and per-service with month-over-month deltas, hunts real waste (idle instances, orphaned volumes, data-transfer bleed) instead of nagging you to buy Reserved Instances, and posts a smart HTML/PDF report to Slack. The headline feature is the part everyone else skips: a tiered least-privilege IAM setup (copy-paste policy, one-click CloudFormation, or admin bootstrap) so you can actually share it with a colleague. ## When to Use This CLI Reach for this CLI when someone asks what
