yq
ELI5 — The Vibe Check
yq is to YAML what jq is to JSON — a command-line tool that lets you read and modify YAML files without opening them in an editor. Essential for anyone swimming in Kubernetes manifests, Helm charts, or GitHub Actions workflows. Particularly useful in CI scripts where you need to bump a version number without sed.

jq
Your API returns 400 lines of JSON. You want just the name field from every object in the users array. 'curl url | jq .users[].name' does it in one pipe.
ripgrep
ripgrep (rg) does what grep does but much faster and smarter. It automatically skips node_modules, .git dirs, and anything in your .gitignore.
tmux
tmux lets you have multiple terminal windows inside one terminal, and — crucially — sessions survive if your SSH connection drops.
