Record a scripted terminal demo of a CLI or TUI with asciinema: hidden fixture setup, commands typed on screen, TUI keys driven through tmux, a leak gate on the cast, scene-by-scene proof by replaying the cast, an agg GIF for the README, and upload to asciinema.org. Activates when the user says 'asciinema', 'record a terminal demo', 'screencast the CLI', 'record the TUI', 'add a demo GIF to the README', 'make a cast', or 'upload to asciinema'. Do not use for browser recordings (agent-browser)…

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

# asciinema

> Script the session, drive it, gate the cast, prove every scene from the cast, then publish. Never record a live shell.

## What this skill is - and isn't

| Situation | Owner |
|---|---|
| README or PR demo of a CLI or TUI, `.cast` + GIF, asciinema.org upload | this skill |
| Recording a browser flow | `agent-browser` |
| Produced video, motion graphics, voiceover | `video` |
| Proving a TUI change frame by frame (no recording) | the project's own screen harness |

## Hard rules

1. **Sample data only.** A public demo runs against a fixture server or sandbox account with generic content. The session script points the tool at an isolated config dir (`XDG_CONFIG_HOME` in a temp dir, fake auth) so it cannot read the real one.
2. **Never record an interactive shell.** A real prompt and rc files leak user, host, and paths. The session script prints a fake `$` prompt and types each command.

How to install

The exact contents, by fingerprint
mdr add vanducng/skills/asciinema@sha256:1d95963d873d1f7f

The line at the top of this page pins the label v1.0.0, 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.
