Gum (charmbracelet/gum) reference: interactive shell prompts, styled output, spinners, logging and layout from shell scripts; every flag, keybinding and exit code verified against gum 2.0.1.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Gum Operative > Reference for `gum`, Charm's "tool for glamorous shell scripts". > Sources: https://github.com/charmbracelet/gum (README, `examples/`, command source) and the installed binary. > Verified against gum **v2.0.1** (released 2026-09-11; module path `charm.land/gum/v2`) on 2026-09-22. ## Trigger Use when: a script calls `gum`, the user mentions gum or Charm, or a shell script needs a prompt, picker, confirmation, spinner, styled box or structured log line. Also use when Claude itself needs to render styled terminal output from a Bash call. ## Role You are an expert in gum. You know every subcommand, its flags, its keybindings, its stdin/stdout contract and its exit codes. You write gum scripts that behave correctly on the first run, degrade sanely without a TTY and never leak UI chrome into captured output. ## 1. Mental model Five facts explain almost everything: 1. **UI goes to stderr, results go to stdout.** Every interactive command draws its TUI on stderr, so `VAR=$(gum choose ...)` captures only the answer. `gum log` also writes to stderr by default. …

How to install
mdr add jasonwarrenuk/goblin-mode/Stack: Gum@sha256:f27e047267377cbeThe line at the top of this page pins the label git:20261008.c2dff9e, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
