Record Demo

Record a demo of $ARGUMENTS using VHS.

1. Check VHS is installed: Run which vhs. If not found, tell the user to install it with brew install vhs.

2. Create a .tape file in demos/ (create the directory if needed). Use this template:

   # Demo: <description>
   Output demos/<name>.gif    # Always use .gif format
   
   Set Shell "zsh"
   Set FontSize 16
   Set Width 1200
   Set Height 600
   Set Theme "Catppuccin Mocha"
   Set TypingSpeed 75ms
   Set Padding 20
   
   Type "<command>"
   Sleep 500ms
   Enter
   Sleep 3s
   

3. VHS Tape DSL reference: For the full command reference, see vhs-reference.md.

4. Tips for good demos:

   • Add Sleep after commands to let output render and be readable
   • Use Hide/Show to run setup commands invisibly
   • Keep demos short and focused (under 30 seconds)
   • Add a Sleep 3s at the end so viewers can see final output
   • Always add a Sleep 500ms pause after each Type line (before Enter) to mimic a human pause
   • For this project, use ./bin/slack directly as the CLI binary path (do NOT export PATH)
   • When demoing from an app directory, use Hide to cd into the app, then use ../bin/slack as the binary path
   • Prefer passing app IDs directly (e.g. --app A12345) to avoid interactive prompts when the ID is known

5. Run the recording: Execute vhs <filename>.tape to generate the output file.

6. Review: Open the demos/ directory with open demos/ so the user can review the output.
