What it does
CLI Demo Generator is an agent skill from daymade/claude-code-skills. Generates professional animated CLI demos as GIFs using VHS terminal recordings. Use to create terminal demos, record CLI workflows as GIFs, generate animated documentation, build demo tapes for README files, or showcase any command-line tool visually: record terminal / VHS tape / demo GIF / animate my CLI.
Its SKILL.md is about 1.7k tokens, which your agent loads only when the skill is triggered. The skill folder holds 15 other files, including scripts, reference files and assets (for example `assets/examples/batch-config.yaml`, `references/advanced_patterns.md` and `references/best_practices.md`).
It sits in Development. The repository describes itself as: Professional Claude Code skills marketplace featuring production-ready skills for enhanced development workflows. The licence is MIT.
When your agent uses it
- Create terminal demos
- Record CLI workflows as GIFs
- Generate animated documentation
- Build demo tapes for README files
Example prompts
- “Use the cli-demo-generator skill to generate professional animated CLI demos as GIFs using VHS terminal recordings”
- “/cli-demo-generator”
Requirements
- Python 3
- Node.js
- A Bash shell
Workflow steps
4 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 3c268d6. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 3 files in scripts/ (Python and Shell), which the agent can run.
Shell commands in SKILL.md call:
python3brewbashffmpeg
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
CLI Demo Generator loads about 1.7k tokens when it runs, and up to ~6.1k if it reads all its reference files. Until then it costs about 82 tokens; SKILL.md has 475 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

- Generates professional animated CLI demos as GIFs using VHS terminal recordings. Use to create terminal demos, record CLI workflows as GIFs, generate animated documentation, build demo tapes for README files, or showcase any command-line tool visually: record terminal / VHS tape / demo GIF / animate my CLI.
CLI Demo Generator
Create professional animated CLI demos. Four approaches, from fully automated to pixel-precise manual control.
Quick Start
Simplest path — give commands, get GIF:
python3 ${CLAUDE_SKILL_DIR}/scripts/auto_generate_demo.py \
-c "npm install my-package" \
-c "npm run build" \
-o demo.gifSelf-bootstrapping demo — for repeatable recordings that clean their own state:
python3 ${CLAUDE_SKILL_DIR}/scripts/auto_generate_demo.py \
-c "npm install my-package" \
-c "npm run build" \
-o demo.gif \
--bootstrap "npm uninstall my-package 2>/dev/null" \
--speed 2Critical: VHS Parser Limitations
VHS Type strings cannot contain $, \", or backticks. These cause parse errors:
# FAILS — VHS parser rejects special chars
Type "echo \"hello $USER\""
Type "claude() { command claude \"$@\"; }"Workaround: base64 encode the command, decode at runtime:
# 1. Encode your complex command
echo 'claude() { command claude "$@" 2>&1 | grep -v "noise"; }' | base64
# Output: Y2xhdWRlKCkgey4uLn0K
# 2. Use in tape
Type "echo Y2xhdWRlKCkgey4uLn0K | base64 -d > /tmp/wrapper.sh && source /tmp/wrapper.sh"This pattern is essential for output filtering, function definitions, and any command with shell special characters.
Approaches
1. Automated Generation (Recommended)
python3 ${CLAUDE_SKILL_DIR}/scripts/auto_generate_demo.py \
-c "command1" -c "command2" \
-o output.gif \
--title "My Demo" \
--theme "Catppuccin Latte" \
--font-size 24 \
--width 1400 --height 600| Flag | Default | Description |
|---|---|---|
-c | required | Command to include (repeatable) |
-o | required | Output GIF path |
--title | none | Title shown at start |
--theme | Dracula | VHS theme name |
--font-size | 16 | Font size in pt |
--width | 1400 | Terminal width px |
--height | 700 | Terminal height px |
--bootstrap | none | Hidden setup command (repeatable) |
--filter | none | Regex pattern to filter from output |
--speed | 1 | Playback speed multiplier (uses gifsicle) |
--no-execute | false | Generate .tape only |
Smart timing: install/build/test/deploy → 3s, ls/pwd/echo → 1s, others → 2s.
2. Batch Generation
Create multiple demos from one config:
# demos.yaml
demos:
- name: "Install"
output: "install.gif"
commands: ["npm install my-package"]
- name: "Usage"
output: "usage.gif"
commands: ["my-package --help", "my-package run"]python3 ${CLAUDE_SKILL_DIR}/scripts/batch_generate.py demos.yaml --output-dir ./gifs3. Interactive Recording
Record a live terminal session:
bash ${CLAUDE_SKILL_DIR}/scripts/record_interactive.sh output.gif --theme "Catppuccin Latte"
# Type commands naturally, Ctrl+D when doneRequires asciinema (brew install asciinema).
4. Manual Tape File
For maximum control, write a tape directly. Templates in assets/templates/:
basic.tape— simple command sequenceinteractive.tape— typing simulationself-bootstrap.tape— self-cleaning demo with hidden setup (recommended for repeatable demos)
Advanced Patterns
These patterns come from production use. See references/advanced_patterns.md for full details.
Self-Bootstrapping Demos
Demos that clean previous state, set up environment, and hide all of it from the viewer:
Hide
Type "cleanup-previous-state 2>/dev/null"
Enter
Sleep 2s
Type "clear"
Enter
Sleep 500ms
Show
Type "the-command-users-see"
Enter
Sleep 3sThe Hide → commands → clear → Show sequence is critical. clear wipes the terminal buffer so hidden commands don't leak into the GIF.
Output Noise Filtering
Filter noisy progress lines from commands that produce verbose output:
# Hidden: create a wrapper function that filters noise
Hide
Type "echo <base64-encoded-wrapper> | base64 -d > /tmp/w.sh && source /tmp/w.sh"
Enter
Sleep 500ms
Type "clear"
Enter
Sleep 500ms
Show
# Visible: clean command, filtered output
Type "my-noisy-command"
Enter
Sleep 3sFrame Verification
After recording, verify GIF content by extracting key frames:
# Extract frames at specific positions
ffmpeg -i demo.gif -vf "select=eq(n\,100)" -frames:v 1 /tmp/frame.png -y 2>/dev/null
# View the frame (Claude can read images)
# Use Read tool on /tmp/frame.png to verify contentShow full SKILL.md (192 more words)Show less
Post-Processing Speed-Up
Use gifsicle to speed up recordings without re-recording:
# 2x speed (halve frame delay)
gifsicle -d2 original.gif "#0-" > fast.gif
# 1.5x speed
gifsicle -d4 original.gif "#0-" > faster.gifTemplate Placeholder Pattern
Keep tape files generic with placeholders, replace at build time:
# In tape file
Type "claude plugin marketplace add MARKETPLACE_REPO"
# In build script
sed "s|MARKETPLACE_REPO|$DETECTED_REPO|g" template.tape > rendered.tape
vhs rendered.tapeTiming & Sizing Reference
| Context | Width | Height | Font | Duration |
|---|---|---|---|---|
| README/docs | 1400 | 600 | 16-20 | 10-20s |
| Presentation | 1800 | 900 | 24 | 15-30s |
| Compact embed | 1200 | 600 | 14-16 | 10-15s |
| Wide output | 1600 | 800 | 16 | 15-30s |
See references/best_practices.md for detailed guidelines.
Troubleshooting
| Problem | Solution |
|---|---|
| VHS not installed | brew install charmbracelet/tap/vhs |
| gifsicle not installed | brew install gifsicle |
| GIF too large | Reduce dimensions, sleep times, or use --speed 2 |
| Text wraps/breaks | Increase --width or decrease --font-size |
VHS parse error on $ or \" | Use base64 encoding (see Critical section above) |
| Hidden commands leak into GIF | Add clear + Sleep 500ms before Show |
| Commands execute before previous finishes | Increase Sleep duration |
Tape File Syntax
references/vhs_syntax.md is the full VHS tape-file reference — every command,
setting, and key name, with the argument forms each accepts. Read it when writing
a tape by hand, when a tape parses but behaves unexpectedly, or when you need a
command this SKILL.md does not show an example of.
Dependencies
Required: VHS (brew install charmbracelet/tap/vhs)
Optional: gifsicle (speed-up), asciinema (interactive recording), ffmpeg (frame verification), PyYAML (batch YAML configs)
