This skill should be used when the user names Charmbracelet VHS, asks to use the `vhs` CLI, wants a terminal recording, terminal GIF, terminal MP4/WebM, `.tape` file, scripted terminal demo, or a reproducible command-line screencast.

Prompt
I need a terminal tape file script to generate a clean demo GIF of our command-line tool `fastpack`. The script should silently set up a temporary test workspace, run `fastpack build`, and wait until it finishes before finishing the recording.

VHS Terminal Recorder
When to use
Use this skill only when vhs or Charmbracelet VHS is actually the right surface:
user says vhs, Charmbracelet VHS, .tape, terminal GIF, terminal recording, command-line screencast, or scripted terminal demo
docs need a reproducible recording of CLI behavior
an existing VHS tape needs authoring, validation, rendering, or debugging
Do not use it for arbitrary desktop capture, browser product tours, video editing, or one-off interactive work that cannot be made deterministic. Use a video/screen-capture workflow instead when the subject is not a terminal.
Mental model
VHS runs a tape file in a pseudo-terminal and renders the terminal session to GIF, MP4, or WebM. Treat a tape like a small executable test:
the tape must create or point at deterministic state
commands shown to viewers should be short and intentional
setup belongs behind Hide / Show
vhs validate checks tape syntax but does not prove the commands work
vhs <file> executes the tape and can mutate files, hit the network, or run project commands
This skill is not the VHS language reference. For exact syntax, generate or inspect live docs:
vhs --help
vhs manual
vhs new /tmp/example.tape
vhs validate /tmp/example.tape
