Three cloud-native batteries — k8s (kubectl + ctx/ns + knstoggle), docker (run/compose + dprune/dsh), tofu (opentofu-or-terraform auto-fallback).

Estante shell-package stdlib — eight frost-and-vanilla compatible batteries: prelude / fs / git / prompt / modern-unix / fp / types / test. Frost-free out of the box: every battery sources from POSIX bash/zsh. The test battery ships an RSpec-style describe/it/expect framework with 14 matchers.

Four batteries for structured-data + plaintext wrangling — json (jq), yaml (yq), csv (qsv/xsv), text (awk/sort/uniq shortcuts).

Five fzf-powered pickers — fzf (file/dir + defaults), fzf-history (Ctrl-R), fzf-cd (zoxide/dirstack), fzf-kill (process), fzf-git (branch/log/file/stash). Fail-soft on absent fzf or companion tools.

Daily-driver helpers for the pleme-io fleet — caixa workflows (feira), frost-lisp dev loop, estante-dev (cache + build), fleet (krio/kpd kubectl + pangea-reconcile + akeyless + git-stack).
