Tape files define commands, timing, and terminal appearance.\n\n## Required TodoWrite Items\n\n```\n- Locate and validate tape file\n- Check VHS installation status\n- Execute VHS recording\n- Verify output GIF creation\n```\n\n## Module Reference\n\n- See `modules/tape-syntax.md` for VHS tape file directives\n- See `modules/execution.md` for recording workflow details\n\n## Workflow\n\n### Phase 1: Validate Tape File\n\n1. Confirm tape file exists at specified path\n2. Read tape file contents\n3. Verify required directives:\n - `Output` directive specifies GIF destination\n - At least one action command (Type, Enter, etc.)\n\n### Phase 2: Check VHS Installation\n\n```bash\nwhich vhs && vhs --version\n```\n\nIf not installed:\n```bash\n# Linux/WSL\ngo install github.com/charmbracelet/vhs@latest\n\n# macOS\nbrew install charmbracelet/tap/vhs\n\n# Also requires ttyd and ffmpeg\n```\n\n### Phase 3: Execute Recording\n\n```bash\nvhs \n```\n\nVHS will:\n1. Parse tape file directives\n2. Launch virtual terminal (ttyd)\n3. Execute commands with timing\n4. Capture frames\n5. Encode to GIF using ffmpeg\n\n### Phase 4: Verify Output\n\n1. Check GIF file exists at Output path\n2. Verify file size is non-zero\n3. Report success with output location\n\n## Exit Criteria\n\n- GIF file created at specified Output path\n- File size indicates successful recording (typically >50KB)\n- No error messages from VHS execution\n## Troubleshooting\n\n### Common Issues\n\nIf `vhs` is not found, verify that your Go bin directory is in your `PATH` (typically `~/go/bin`). If the recording fails to start, ensure `ttyd` and `ffmpeg` are installed, as VHS depends on them for terminal emulation and video encoding. For \"permission denied\" errors when writing the GIF, check that the output directory exists and is writable.\n\nFile v1.9.19:_meta.json\n\n{\n \"ownerId\": \"kn7d107jg9jv602h9ytsegydq184a42s\",\n \"slug\": \"nm-scry-vhs-recording\",\n \"version\": \"1.9.19\",\n \"publishedAt\": 1787750581870\n}\n\nFile v1.9.19:modules/execution.md\n\n# VHS Execution Guide\n\n## Pre-flight Checks\n\n### VHS Installation\n\n```bash\n# Check if installed\nwhich vhs\n\n# Check version\nvhs --version\n```\n\n### Dependencies\n\nVHS requires:\n- **ttyd**: Terminal emulator for web\n- **ffmpeg**: Video/image encoding\n\n```bash\n# Verify dependencies\nwhich ttyd ffmpeg\n```\n\n### Installation\n\n```bash\n# Go (recommended)\ngo install github.com/charmbracelet/vhs@latest\n\n# macOS\nbrew install charmbracelet/tap/vhs\n\n# Arch Linux\nyay -S vhs\n\n# Nix\nnix-env -iA nixpkgs.vhs\n```\n\n### Tape File Validation\n\nCheck tape file before execution:\n\n```bash\n# Verify file exists\ntest -f tape-file.tape && echo \"Found\" || echo \"Missing\"\n\n# Check for Output directive\nrg -q \"^Output\" tape-file.tape && echo \"Has output\" || echo \"No output directive\"\n# fallback: grep -q \"^Output\" tape-file.tape\n\n# Validate syntax (dry run)\nvhs validate tape-file.tape\n```\n\n## Environment Setup\n\n### Terminal Environment\n\nVHS creates an isolated terminal. Set environment variables in the tape:\n\n```tape\nSet Env \"HOME\" \"/home/user\"\nSet Env \"PATH\" \"/usr/local/bin:/usr/bin:/bin\"\nSet Env \"TERM\" \"xterm-256color\"\n```\n\n### Working Directory\n\nVHS runs from the directory containing the tape file. For different directories:\n\n```tape\nHide\nType \"cd /path/to/project\"\nEnter\nSleep 500ms\nShow\n```\n\n## Running VHS\n\n### Basic Execution\n\n```bash\nvhs tape-file.tape\n```\n\n### With Options\n\n```bash\n# Publish to vhs.charm.sh (public)\nvhs tape-file.tape --publish\n\n# Output to specific location\nvhs tape-file.tape -o custom-output.gif\n```\n\n### Batch Recording\n\n```bash\n# Record all tape files\nfor tape in *.tape; do\n vhs \"$tape\"\ndone\n```\n\n## Error Handling\n\n### Common Issues\n\n**ttyd not found**\n```bash\n# Install ttyd\ngo install github.com/aspect-build/aspect-cli/pkg/ttyd@latest\n# Or via package manager\n```\n\n**ffmpeg errors**\n```bash\n# validate ffmpeg is installed with required codecs\nffmpeg -version\n```\n\n**Permission denied**\n```bash\n# Check write permissions for output directory\nls -la \"$(dirname output.gif)\"\n```\n\n**Empty output**\n- Verify commands produce visible output\n- Increase Sleep times after commands\n- Check terminal dimensions fit content\n\n### Debug Mode\n\n```bash\n# Verbose output\nVHS_DEBUG=1 vhs tape-file.tape\n```\n\n## WSL2 Considerations\n\n### Graphics Support\n\nVHS in WSL2 may require:\n- WSLg enabled (Windows 11+)\n- X server for older Windows 10\n\n### Path Handling\n\nUse Linux-style paths in tape files:\n```tape\n# Correct\nOutput /home/user/output.gif\n\n# Avoid Windows paths\n# Output C:\\Users\\...\n```\n\n### Performance\n\nWSL2 disk I/O to Windows filesystem is slow. Keep tapes and outputs on Linux filesystem:\n\n```bash\n# Good: Linux filesystem\n/home/user/recordings/\n\n# Slow: Windows mount\n/mnt/c/Users/...\n```\n\n### Font Availability\n\nInstall fonts in WSL2:\n```bash\nsudo apt install fonts-jetbrains-mono\nfc-cache -fv\n```\n\n## Output Verification\n\nAfter recording:\n\n```bash\n# Check file exists and has content\nls -la output.gif\n\n# Verify file type\nfile output.gif\n\n# Check dimensions (requires ImageMagick)\nidentify output.gif | head -1\n```\n\n## Integration with Documentation\n\nMove outputs to documentation directories:\n\n```bash\n# Move to docs\nmv output.gif docs/images/\n\n# Update markdown references\n# ![Demo](images/output.gif)\n```\n\nFile v1.9.19:modules/tape-syntax.md\n\n# VHS Tape Syntax Reference\n\n## Metadata Comments\n\nCustom metadata annotations for documentation integration:\n\n```tape\n# @title: Command Demo\n# @description: Demonstrates the CLI workflow\n# @step: 1\n# @docs-brief: Quick overview for documentation\n# @book-detail: Extended explanation for book chapters\n```\n\n## Output Directive\n\nSpecifies the output file path (required):\n\n```tape\nOutput demo.gif\n```\n\nSupported formats: `.gif`, `.mp4`, `.webm`\n\n## Set Directives\n\nConfigure terminal appearance and behavior:\n\n```tape\n# Typography\nSet FontSize 14\nSet FontFamily \"JetBrains Mono\"\n\n# Dimensions\nSet Width 1200\nSet Height 600\n\n# Appearance\nSet Theme \"Dracula\"\nSet Padding 20\nSet Margin 10\nSet MarginFill \"#674EFF\"\nSet BorderRadius 8\n\n# Timing\nSet TypingSpeed 50ms\nSet Framerate 60\n\n# Environment\nSet Env \"TERM\" \"xterm-256color\"\nSet Env \"PS1\" \"$ \"\n\n# Window\nSet Shell \"bash\"\nSet WindowBar Colorful\nSet WindowBarSize 40\n```\n\n## Action Commands\n\n### Type\n\nTypes text into the terminal:\n\n```tape\nType \"echo 'Hello World'\"\nType@50ms \"slower typing\"\n```\n\n### Enter\n\nSends Enter key (execute command):\n\n```tape\nEnter\n```\n\n### Sleep\n\nPause for duration:\n\n```tape\nSleep 500ms\nSleep 2s\n```\n\n### Key Combinations\n\n```tape\nCtrl+C\nCtrl+D\nCtrl+L\nEscape\nTab\nBackspace\nUp\nDown\nLeft\nRight\nSpace\n```\n\n### Screenshot\n\nCapture a still frame:\n\n```tape\nScreenshot output.png\n```\n\n### Hide/Show\n\nControl visibility of actions:\n\n```tape\nHide\nType \"secret setup commands\"\nEnter\nShow\n```\n\n## Best Practices\n\n### Echo vs Commands\n\n**NEVER use `echo` to simulate or replace real command output.** Echo should only be used for:\n\n- Printing explanatory messages or headers\n- Simple text output demonstrations\n- Comments that need to appear in the terminal\n\n**ALWAYS prefer actual commands** that demonstrate functionality:\n\n```tape\n# BAD: Simulating output with echo\nType \"echo 'tool-a, tool-b, tool-c'\"\nEnter\n\n# GOOD: Using the actual command\nType \"my-cli --list-tools\"\nEnter\n```\n\nIf a command doesn't exist to show what you need, consider:\n1. Adding a flag or subcommand to the CLI being demonstrated\n2. Using the actual data source (file, API, etc.)\n3. Rethinking what the demo should show\n\n**Rationale**: Tutorials should demonstrate real functionality. Echoing data teaches users nothing about the actual tool and may become stale as the tool evolves.\n\n### MCP Tool Demonstrations\n\nWhen demonstrating MCP (Model Context Protocol) functionality, show how tools are used within the host environment (e.g., Claude Code) rather than calling CLI equivalents:\n\n```tape\n# POOR: Using CLI instead of MCP\nType \"skrills metrics\"\n\n# BETTER: Explain MCP tool usage\nType \"# In Claude Code, ask: 'Show me skill statistics'\"\nType \"# Claude calls the skill-metrics MCP tool automatically\"\n```\n\n## Advanced Features\n\n### Split Panes\n\nCreate multi-pane layouts:\n\n```tape\nSplit\nType@left \"echo 'Left pane'\"\nEnter@left\nType@right \"echo 'Right pane'\"\nEnter@right\n```\n\n### Source\n\nInclude other tape files:\n\n```tape\nSource common-setup.tape\n```\n\n### Require\n\nvalidate programs are available:\n\n```tape\nRequire echo\nRequire git\n```\n\n## Complete Example\n\n```tape\n# @title: Git Status Demo\n# @description: Shows git status workflow\n# @step: 1\n\nOutput git-demo.gif\n\nSet FontSize 16\nSet Width 1000\nSet Height 400\nSet Theme \"Catppuccin Mocha\"\nSet TypingSpeed 75ms\n\nHide\nType \"cd ~/project\"\nEnter\nSleep 500ms\nShow\n\nType \"git status\"\nSleep 500ms\nEnter\nSleep 2s\n\nType \"git add .\"\nSleep 500ms\nEnter\nSleep 1s\n\nType \"git commit -m 'Update docs'\"\nSleep 500ms\nEnter\nSleep 2s\n```\n\nFile v1.9.19:skill-card.md\n\n## Description:\n\nGenerates terminal recordings using VHS tape scripts and produces GIF outputs.\n\nThis skill is ready for commercial/non-commercial use.\n\n## Publisher:\n\n[athola](https://clawhub.ai/user/athola)\n\n### License/Terms of Use:\n\nMIT-0\n\n## Use Case:\n\nDevelopers and documentation authors use this skill to validate VHS tape files, run terminal recording workflows, and produce GIF demos for CLI documentation and tutorials.\n\n### Deployment Geography for Use:\n\nGlobal\n\n## Known Risks and Mitigations:\n\nRisk: VHS tape files can execute terminal commands and include other Source files.\n\nMitigation: Review each tape and included Source file before running it, and avoid untrusted tapes.\n\nRisk: Terminal recordings can expose secrets, environment values, or sensitive command output.\n\nMitigation: Use disposable demo projects where practical and sanitize terminal output before sharing recordings.\n\nRisk: Using the publish option can make recordings public.\n\nMitigation: Use --publish only for recordings that are intended to be publicly accessible.\n\nRisk: Mutable install examples can change the installed tool behavior over time.\n\nMitigation: Review the toolchain before use and prefer pinned dependency versions for repeatable production workflows.\n\n## Reference(s):\n\n- [ClawHub skill page](https://clawhub.ai/athola/skills/nm-scry-vhs-recording)\n- [Project homepage](https://github.com/athola/claude-night-market/tree/master/plugins/scry)\n- [VHS execution guide](modules/execution.md)\n- [VHS tape syntax reference](modules/tape-syntax.md)\n\n## Skill Output:\n\n**Output Type(s):** [shell commands, guidance, files]\n\n**Output Format:** [Markdown guidance with bash and tape code blocks]\n\n**Output Parameters:** [1D]\n\n**Other Properties Related to Output:** [Produces or verifies GIF outputs from VHS tape execution when the required local tools are installed.]\n\n## Skill Version(s):\n\n1.9.19 (source: server release evidence; artifact frontmatter says 1.9.8)\n\n## Ethical Considerations:\n\nUsers should evaluate whether this skill is appropriate for their environment, review any generated or modified files before relying on them, and apply their organization's safety, security, and compliance requirements before deployment.\n\nArchive v1.9.17: 5 files, 6316 bytes\n\nFiles: modules/execution.md (3225b), modules/tape-syntax.md (3513b), skill-card.md (2007b), SKILL.md (2887b), _meta.json (141b)\n\nFile v1.9.17:SKILL.md\n\n---\nname: vhs-recording\ndescription: Generates terminal recordings using VHS tape scripts and produces GIF outputs\nversion: 1.9.8\ntriggers:\n - vhs\n - terminal\n - recording\n - gif\n - demo\n - tutorial\n - creating demo GIFs or documenting CLI workflows for tutorials\nmetadata: {\"openclaw\": {\"homepage\": \"https://github.com/athola/claude-night-market/tree/master/plugins/scry\", \"emoji\": \"\\ud83e\\udd9e\"}}\nsource: claude-night-market\nsource_plugin: scry\n---\n\n> **Night Market Skill** — ported from [claude-night-market/scry](https://github.com/athola/claude-night-market/tree/master/plugins/scry).

Confirm tape file exists at specified path\n2. Read tape file contents\n3. Verify required directives:\n - `Output` directive specifies GIF destination\n - At least one action command (Type, Enter, etc.)\n\n### Phase 2: Check VHS Installation\n\n```bash\nwhich vhs && vhs --version\n```\n\nIf not installed:\n```bash\n# Linux/WSL\ngo install github.com/charmbracelet/vhs@latest\n\n# macOS\nbrew install charmbracelet/tap/vhs\n\n# Also requires ttyd and ffmpeg\n```\n\n### Phase 3: Execute Recording\n\n```bash\nvhs \n```\n\nVHS will:\n1. Parse tape file directives\n2. Launch virtual terminal (ttyd)\n3. Execute commands with timing\n4. Capture frames\n5. Encode to GIF using ffmpeg\n\n### Phase 4: Verify Output\n\n1. Check GIF file exists at Output path\n2. Verify file size is non-zero\n3. Report success with output location\n\n## Exit Criteria\n\n- GIF file created at specified Output path\n- File size indicates successful recording (typically >50KB)\n- No error messages from VHS execution\n## Troubleshooting\n\n### Common Issues\n\nIf `vhs` is not found, verify that your Go bin directory is in your `PATH` (typically `~/go/bin`). If the recording fails to start, ensure `ttyd` and `ffmpeg` are installed, as VHS depends on them for terminal emulation and video encoding. For \"permission denied\" errors when writing the GIF, check that the output directory exists and is writable.\n\nFile v1.9.14:_meta.json\n\n{\n \"ownerId\": \"kn7d107jg9jv602h9ytsegydq184a42s\",\n \"slug\": \"nm-scry-vhs-recording\",\n \"version\": \"1.9.14\",\n \"publishedAt\": 1782842825693\n}\n\nFile v1.9.14:modules/execution.md\n\n# VHS Execution Guide\n\n## Pre-flight Checks\n\n### VHS Installation\n\n```bash\n# Check if installed\nwhich vhs\n\n# Check version\nvhs --version\n```\n\n### Dependencies\n\nVHS requires:\n- **ttyd**: Terminal emulator for web\n- **ffmpeg**: Video/image encoding\n\n```bash\n# Verify dependencies\nwhich ttyd ffmpeg\n```\n\n### Installation\n\n```bash\n# Go (recommended)\ngo install github.com/charmbracelet/vhs@latest\n\n# macOS\nbrew install charmbracelet/tap/vhs\n\n# Arch Linux\nyay -S vhs\n\n# Nix\nnix-env -iA nixpkgs.vhs\n```\n\n### Tape File Validation\n\nCheck tape file before execution:\n\n```bash\n# Verify file exists\ntest -f tape-file.tape && echo \"Found\" || echo \"Missing\"\n\n# Check for Output directive\nrg -q \"^Output\" tape-file.tape && echo \"Has output\" || echo \"No output directive\"\n# fallback: grep -q \"^Output\" tape-file.tape\n\n# Validate syntax (dry run)\nvhs validate tape-file.tape\n```\n\n## Environment Setup\n\n### Terminal Environment\n\nVHS creates an isolated terminal.

Tape files define commands, timing, and terminal appearance.\n\n## Required TodoWrite Items\n\n```\n- Locate and validate tape file\n- Check VHS installation status\n- Execute VHS recording\n- Verify output GIF creation\n```\n\n## Module Reference\n\n- See `modules/tape-syntax.md` for VHS tape file directives\n- See `modules/execution.md` for recording workflow details\n\n## Workflow\n\n### Phase 1: Validate Tape File\n\n1. Confirm tape file exists at specified path\n2. Read tape file contents\n3. Verify required directives:\n - `Output` directive specifies GIF destination\n - At least one action command (Type, Enter, etc.)\n\n### Phase 2: Check VHS Installation\n\n```bash\nwhich vhs && vhs --version\n```\n\nIf not installed:\n```bash\n# Linux/WSL\ngo install github.com/charmbracelet/vhs@latest\n\n# macOS\nbrew install charmbracelet/tap/vhs\n\n# Also requires ttyd and ffmpeg\n```\n\n### Phase 3: Execute Recording\n\n```bash\nvhs \n```\n\nVHS will:\n1. Parse tape file directives\n2. Launch virtual terminal (ttyd)\n3. Execute commands with timing\n4. Capture frames\n5. Encode to GIF using ffmpeg\n\n### Phase 4: Verify Output\n\n1. Check GIF file exists at Output path\n2. Verify file size is non-zero\n3. Report success with output location\n\n## Exit Criteria\n\n- GIF file created at specified Output path\n- File size indicates successful recording (typically >50KB)\n- No error messages from VHS execution\n## Troubleshooting\n\n### Common Issues\n\nIf `vhs` is not found, verify that your Go bin directory is in your `PATH` (typically `~/go/bin`). If the recording fails to start, ensure `ttyd` and `ffmpeg` are installed, as VHS depends on them for terminal emulation and video encoding. For \"permission denied\" errors when writing the GIF, check that the output directory exists and is writable.\n\nFile v1.9.12:_meta.json\n\n{\n \"ownerId\": \"kn7d107jg9jv602h9ytsegydq184a42s\",\n \"slug\": \"nm-scry-vhs-recording\",\n \"version\": \"1.9.12\",\n \"publishedAt\": 1781839242578\n}\n\nFile v1.9.12:modules/execution.md\n\n# VHS Execution Guide\n\n## Pre-flight Checks\n\n### VHS Installation\n\n```bash\n# Check if installed\nwhich vhs\n\n# Check version\nvhs --version\n```\n\n### Dependencies\n\nVHS requires:\n- **ttyd**: Terminal emulator for web\n- **ffmpeg**: Video/image encoding\n\n```bash\n# Verify dependencies\nwhich ttyd ffmpeg\n```\n\n### Installation\n\n```bash\n# Go (recommended)\ngo install github.com/charmbracelet/vhs@latest\n\n# macOS\nbrew install charmbracelet/tap/vhs\n\n# Arch Linux\nyay -S vhs\n\n# Nix\nnix-env -iA nixpkgs.vhs\n```\n\n### Tape File Validation\n\nCheck tape file before execution:\n\n```bash\n# Verify file exists\ntest -f tape-file.tape && echo \"Found\" || echo \"Missing\"\n\n# Check for Output directive\nrg -q \"^Output\" tape-file.tape && echo \"Has output\" || echo \"No output directive\"\n# fallback: grep -q \"^Output\" tape-file.tape\n\n# Validate syntax (dry run)\nvhs validate tape-file.tape\n```\n\n## Environment Setup\n\n### Terminal Environment\n\nVHS creates an isolated terminal. Set environment variables in the tape:\n\n```tape\nSet Env \"HOME\" \"/home/user\"\nSet Env \"PATH\" \"/usr/local/bin:/usr/bin:/bin\"\nSet Env \"TERM\" \"xterm-256color\"\n```\n\n### Working Directory\n\nVHS runs from the directory containing the tape file.

Tape files define commands, timing, and terminal appearance.\n\n## Required TodoWrite Items\n\n```\n- Locate and validate tape file\n- Check VHS installation status\n- Execute VHS recording\n- Verify output GIF creation\n```\n\n## Module Reference\n\n- See `modules/tape-syntax.md` for VHS tape file directives\n- See `modules/execution.md` for recording workflow details\n\n## Workflow\n\n### Phase 1: Validate Tape File\n\n1. Confirm tape file exists at specified path\n2. Read tape file contents\n3. Verify required directives:\n - `Output` directive specifies GIF destination\n - At least one action command (Type, Enter, etc.)\n\n### Phase 2: Check VHS Installation\n\n```bash\nwhich vhs && vhs --version\n```\n\nIf not installed:\n```bash\n# Linux/WSL\ngo install github.com/charmbracelet/vhs@latest\n\n# macOS\nbrew install charmbracelet/tap/vhs\n\n# Also requires ttyd and ffmpeg\n```\n\n### Phase 3: Execute Recording\n\n```bash\nvhs \n```\n\nVHS will:\n1. Parse tape file directives\n2. Launch virtual terminal (ttyd)\n3. Execute commands with timing\n4. Capture frames\n5. Encode to GIF using ffmpeg\n\n### Phase 4: Verify Output\n\n1. Check GIF file exists at Output path\n2. Verify file size is non-zero\n3. Report success with output location\n\n## Exit Criteria\n\n- GIF file created at specified Output path\n- File size indicates successful recording (typically >50KB)\n- No error messages from VHS execution\n## Troubleshooting\n\n### Common Issues\n\nIf `vhs` is not found, verify that your Go bin directory is in your `PATH` (typically `~/go/bin`). If the recording fails to start, ensure `ttyd` and `ffmpeg` are installed, as VHS depends on them for terminal emulation and video encoding. For \"permission denied\" errors when writing the GIF, check that the output directory exists and is writable.\n\nFile v1.0.1:_meta.json\n\n{\n \"ownerId\": \"kn7d107jg9jv602h9ytsegydq184a42s\",\n \"slug\": \"nm-scry-vhs-recording\",\n \"version\": \"1.0.1\",\n \"publishedAt\": 1778077330988\n}\n\nFile v1.0.1:modules/execution.md\n\n# VHS Execution Guide\n\n## Pre-flight Checks\n\n### VHS Installation\n\n```bash\n# Check if installed\nwhich vhs\n\n# Check version\nvhs --version\n```\n\n### Dependencies\n\nVHS requires:\n- **ttyd**: Terminal emulator for web\n- **ffmpeg**: Video/image encoding\n\n```bash\n# Verify dependencies\nwhich ttyd ffmpeg\n```\n\n### Installation\n\n```bash\n# Go (recommended)\ngo install github.com/charmbracelet/vhs@latest\n\n# macOS\nbrew install charmbracelet/tap/vhs\n\n# Arch Linux\nyay -S vhs\n\n# Nix\nnix-env -iA nixpkgs.vhs\n```\n\n### Tape File Validation\n\nCheck tape file before execution:\n\n```bash\n# Verify file exists\ntest -f tape-file.tape && echo \"Found\" || echo \"Missing\"\n\n# Check for Output directive\nrg -q \"^Output\" tape-file.tape && echo \"Has output\" || echo \"No output directive\"\n# fallback: grep -q \"^Output\" tape-file.tape\n\n# Validate syntax (dry run)\nvhs validate tape-file.tape\n```\n\n## Environment Setup\n\n### Terminal Environment\n\nVHS creates an isolated terminal. Set environment variables in the tape:\n\n```tape\nSet Env \"HOME\" \"/home/user\"\nSet Env \"PATH\" \"/usr/local/bin:/usr/bin:/bin\"\nSet Env \"TERM\" \"xterm-256color\"\n```\n\n### Working Directory\n\nVHS runs from the directory containing the tape file. For different directories:\n\n```tape\nHide\nType \"cd /path/to/project\"\nEnter\nSleep 500ms\nShow\n```\n\n## Running VHS\n\n### Basic Execution\n\n```bash\nvhs tape-file.tape\n```\n\n### With Options\n\n```bash\n# Publish to vhs.charm.sh (public)\nvhs tape-file.tape --publish\n\n# Output to specific location\nvhs tape-file.tape -o custom-output.gif\n```\n\n### Batch Recording\n\n```bash\n# Record all tape files\nfor tape in *.tape; do\n vhs \"$tape\"\ndone\n```\n\n## Error Handling\n\n### Common Issues\n\n**ttyd not found**\n```bash\n# Install ttyd\ngo install github.com/aspect-build/aspect-cli/pkg/ttyd@latest\n# Or via package manager\n```\n\n**ffmpeg errors**\n```bash\n# validate ffmpeg is installed with required codecs\nffmpeg -version\n```\n\n**Permission denied**\n```bash\n# Check write permissions for output directory\nls -la \"$(dirname output.gif)\"\n```\n\n**Empty output**\n- Verify commands produce visible output\n- Increase Sleep times after commands\n- Check terminal dimensions fit content\n\n### Debug Mode\n\n```bash\n# Verbose output\nVHS_DEBUG=1 vhs tape-file.tape\n```\n\n## WSL2 Considerations\n\n### Graphics Support\n\nVHS in WSL2 may require:\n- WSLg enabled (Windows 11+)\n- X server for older Windows 10\n\n### Path Handling\n\nUse Linux-style paths in tape files:\n```tape\n# Correct\nOutput /home/user/output.gif\n\n# Avoid Windows paths\n# Output C:\\Users\\...\n```\n\n### Performance\n\nWSL2 disk I/O to Windows filesystem is slow. Keep tapes and outputs on Linux filesystem:\n\n```bash\n# Good: Linux filesystem\n/home/user/recordings/\n\n# Slow: Windows mount\n/mnt/c/Users/...\n```\n\n### Font Availability\n\nInstall fonts in WSL2:\n```bash\nsudo apt install fonts-jetbrains-mono\nfc-cache -fv\n```\n\n## Output Verification\n\nAfter recording:\n\n```bash\n# Check file exists and has content\nls -la output.gif\n\n# Verify file type\nfile output.gif\n\n# Check dimensions (requires ImageMagick)\nidentify output.gif | head -1\n```\n\n## Integration with Documentation\n\nMove outputs to documentation directories:\n\n```bash\n# Move to docs\nmv output.gif docs/images/\n\n# Update markdown references\n# ![Demo](images/output.gif)\n```\n\nFile v1.0.1:modules/tape-syntax.md\n\n# VHS Tape Syntax Reference\n\n## Metadata Comments\n\nCustom metadata annotations for documentation integration:\n\n```tape\n# @title: Command Demo\n# @description: Demonstrates the CLI workflow\n# @step: 1\n# @docs-brief: Quick overview for documentation\n# @book-detail: Extended explanation for book chapters\n```\n\n## Output Directive\n\nSpecifies the output file path (required):\n\n```tape\nOutput demo.gif\n```\n\nSupported formats: `.gif`, `.mp4`, `.webm`\n\n## Set Directives\n\nConfigure terminal appearance and behavior:\n\n```tape\n# Typography\nSet FontSize 14\nSet FontFamily \"JetBrains Mono\"\n\n# Dimensions\nSet Width 1200\nSet Height 600\n\n# Appearance\nSet Theme \"Dracula\"\nSet Padding 20\nSet Margin 10\nSet MarginFill \"#674EFF\"\nSet BorderRadius 8\n\n# Timing\nSet TypingSpeed 50ms\nSet Framerate 60\n\n# Environment\nSet Env \"TERM\" \"xterm-256color\"\nSet Env \"PS1\" \"$ \"\n\n# Window\nSet Shell \"bash\"\nSet WindowBar Colorful\nSet WindowBarSize 40\n```\n\n## Action Commands\n\n### Type\n\nTypes text into the terminal:\n\n```tape\nType \"echo 'Hello World'\"\nType@50ms \"slower typing\"\n```\n\n### Enter\n\nSends Enter key (execute command):\n\n```tape\nEnter\n```\n\n### Sleep\n\nPause for duration:\n\n```tape\nSleep 500ms\nSleep 2s\n```\n\n### Key Combinations\n\n```tape\nCtrl+C\nCtrl+D\nCtrl+L\nEscape\nTab\nBackspace\nUp\nDown\nLeft\nRight\nSpace\n```\n\n### Screenshot\n\nCapture a still frame:\n\n```tape\nScreenshot output.png\n```\n\n### Hide/Show\n\nControl visibility of actions:\n\n```tape\nHide\nType \"secret setup commands\"\nEnter\nShow\n```\n\n## Best Practices\n\n### Echo vs Commands\n\n**NEVER use `echo` to simulate or replace real command output.** Echo should only be used for:\n\n- Printing explanatory messages or headers\n- Simple text output demonstrations\n- Comments that need to appear in the terminal\n\n**ALWAYS prefer actual commands** that demonstrate functionality:\n\n```tape\n# BAD: Simulating output with echo\nType \"echo 'tool-a, tool-b, tool-c'\"\nEnter\n\n# GOOD: Using the actual command\nType \"my-cli --list-tools\"\nEnter\n```\n\nIf a command doesn't exist to show what you need, consider:\n1. Adding a flag or subcommand to the CLI being demonstrated\n2. Using the actual data source (file, API, etc.)\n3. Rethinking what the demo should show\n\n**Rationale**: Tutorials should demonstrate real functionality. Echoing data teaches users nothing about the actual tool and may become stale as the tool evolves.\n\n### MCP Tool Demonstrations\n\nWhen demonstrating MCP (Model Context Protocol) functionality, show how tools are used within the host environment (e.g., Claude Code) rather than calling CLI equivalents:\n\n```tape\n# POOR: Using CLI instead of MCP\nType \"skrills metrics\"\n\n# BETTER: Explain MCP tool usage\nType \"# In Claude Code, ask: 'Show me skill statistics'\"\nType \"# Claude calls the skill-metrics MCP tool automatically\"\n```\n\n## Advanced Features\n\n### Split Panes\n\nCreate multi-pane layouts:\n\n```tape\nSplit\nType@left \"echo 'Left pane'\"\nEnter@left\nType@right \"echo 'Right pane'\"\nEnter@right\n```\n\n### Source\n\nInclude other tape files:\n\n```tape\nSource common-setup.tape\n```\n\n### Require\n\nvalidate programs are available:\n\n```tape\nRequire echo\nRequire git\n```\n\n## Complete Example\n\n```tape\n# @title: Git Status Demo\n# @description: Shows git status workflow\n# @step: 1\n\nOutput git-demo.gif\n\nSet FontSize 16\nSet Width 1000\nSet Height 400\nSet Theme \"Catppuccin Mocha\"\nSet TypingSpeed 75ms\n\nHide\nType \"cd ~/project\"\nEnter\nSleep 500ms\nShow\n\nType \"git status\"\nSleep 500ms\nEnter\nSleep 2s\n\nType \"git add .\"\nSleep 500ms\nEnter\nSleep 1s\n\nType \"git commit -m 'Update docs'\"\nSleep 500ms\nEnter\nSleep 2s\n```\n\nArchive v1.0.0: 4 files, 5176 bytes\n\nFiles: modules/execution.md (3225b), modules/tape-syntax.md (3513b), SKILL.md (2815b), _meta.json (140b)\n\nFile v1.0.0:SKILL.md\n\n---\nname: vhs-recording\ndescription: Generate terminal recordings using VHS tape files, produces GIF outputs\nversion: 1.8.2\ntriggers:\n - vhs\n - terminal\n - recording\n - gif\n - demo\n - tutorial\nmetadata: {\"openclaw\": {\"homepage\": \"https://github.com/athola/claude-night-market/tree/master/plugins/scry\", \"emoji\": \"\\ud83e\\udd9e\"}}\nsource: claude-night-market\nsource_plugin: scry\n---\n\n> **Night Market Skill** — ported from [claude-night-market/scry](https://github.com/athola/claude-night-market/tree/master/plugins/scry).

Report success with output location\n\n## Exit Criteria\n\n- GIF file created at specified Output path\n- File size indicates successful recording (typically >50KB)\n- No error messages from VHS execution\n## Troubleshooting\n\n### Common Issues\n\nIf `vhs` is not found, verify that your Go bin directory is in your `PATH` (typically `~/go/bin`). If the recording fails to start, ensure `ttyd` and `ffmpeg` are installed, as VHS depends on them for terminal emulation and video encoding. For \"permission denied\" errors when writing the GIF, check that the output directory exists and is writable."},{"path":"_meta.json","content":"{\n \"ownerId\": \"kn7d107jg9jv602h9ytsegydq184a42s\",\n \"slug\": \"nm-scry-vhs-recording\",\n \"version\": \"1.9.19\",\n \"publishedAt\": 1787750581870\n}"},{"path":"modules/execution.md","content":"# VHS Execution Guide\n\n## Pre-flight Checks\n\n### VHS Installation\n\n```bash\n# Check if installed\nwhich vhs\n\n# Check version\nvhs --version\n```\n\n### Dependencies\n\nVHS requires:\n- **ttyd**: Terminal emulator for web\n- **ffmpeg**: Video/image encoding\n\n```bash\n# Verify dependencies\nwhich ttyd ffmpeg\n```\n\n### Installation\n\n```bash\n# Go (recommended)\ngo install github.com/charmbracelet/vhs@latest\n\n# macOS\nbrew install charmbracelet/tap/vhs\n\n# Arch Linux\nyay -S vhs\n\n# Nix\nnix-env -iA nixpkgs.vhs\n```\n\n### Tape File Validation\n\nCheck tape file before execution:\n\n```bash\n# Verify file exists\ntest -f tape-file.tape && echo \"Found\" || echo \"Missing\"\n\n# Check for Output directive\nrg -q \"^Output\" tape-file.tape && echo \"Has output\" || echo \"No output directive\"\n# fallback: grep -q \"^Output\" tape-file.tape\n\n# Validate syntax (dry run)\nvhs validate tape-file.tape\n```\n\n## Environment Setup\n\n### Terminal Environment\n\nVHS creates an isolated terminal. Set environment variables in the tape:\n\n```tape\nSet Env \"HOME\" \"/home/user\"\nSet Env \"PATH\" \"/usr/local/bin:/usr/bin:/bin\"\nSet Env \"TERM\" \"xterm-256color\"\n```\n\n### Working Directory\n\nVHS runs from the directory containing the tape file. For different directories:\n\n```tape\nHide\nType \"cd /path/to/project\"\nEnter\nSleep 500ms\nShow\n```\n\n## Running VHS\n\n### Basic Execution\n\n```bash\nvhs tape-file.tape\n```\n\n### With Options\n\n```bash\n# Publish to vhs.charm.sh (public)\nvhs tape-file.tape --publish\n\n# Output to specific location\nvhs tape-file.tape -o custom-output.gif\n```\n\n### Batch Recording\n\n```bash\n# Record all tape files\nfor tape in *.tape; do\n vhs \"$tape\"\ndone\n```\n\n## Error Handling\n\n### Common Issues\n\n**ttyd not found**\n```bash\n# Install ttyd\ngo install github.com/aspect-build/aspect-cli/pkg/ttyd@latest\n# Or via package manager\n```\n\n**ffmpeg errors**\n```bash\n# validate ffmpeg is installed with required codecs\nffmpeg -version\n```\n\n**Permission denied**\n```bash\n# Check write permissions for output directory\nls -la \"$(dirname output.gif)\"\n```\n\n**Empty output**\n- Verify commands produce visible output\n- Increase Sleep times after commands\n- Check terminal dimensions fit content\n\n### Debug Mode\n\n```bash\n# Verbose output\nVHS_DEBUG=1 vhs tape-file.tape\n```\n\n## WSL2 Considerations\n\n### Graphics Support\n\nVHS in WSL2 may require:\n- WSLg enabled (Windows 11+)\n- X server for older Windows 10\n\n### Path Handling\n\nUse Linux-style paths in tape files:\n```tape\n# Correct\nOutput /home/user/output.gif\n\n# Avoid Windows paths\n# Output C:\\Users\\...\n```\n\n### Performance\n\nWSL2 disk I/O to Windows filesystem is slow. Keep tapes and outputs on Linux filesystem:\n\n```bash\n# Good: Linux filesystem\n/home/user/recordings/\n\n# Slow: Windows mount\n/mnt/c/Users/...\n```\n\n### Font Availability\n\nInstall fonts in WSL2:\n```bash\nsudo apt install fonts-jetbrains-mono\nfc-cache -fv\n```\n\n## Output Verification\n\nAfter recording:\n\n```bash\n# Check file exists and has content\nls -la output.gif\n\n# Verify file type\nfile output.gif\n\n# Check dimensions (requires ImageMagick)\nid"},{"path":"modules/tape-syntax.md","content":"# VHS Tape Syntax Reference\n\n## Metadata Comments\n\nCustom metadata annotations for documentation integration:\n\n```tape\n# @title: Command Demo\n# @description: Demonstrates the CLI workflow\n# @step: 1\n# @docs-brief: Quick overview for documentation\n# @book-detail: Extended explanation for book chapters\n```\n\n## Output Directive\n\nSpecifies the output file path (required):\n\n```tape\nOutput demo.gif\n```\n\nSupported formats: `.gif`, `.mp4`, `.webm`\n\n## Set Directives\n\nConfigure terminal appearance and behavior:\n\n```tape\n# Typography\nSet FontSize 14\nSet FontFamily \"JetBrains Mono\"\n\n# Dimensions\nSet Width 1200\nSet Height 600\n\n# Appearance\nSet Theme \"Dracula\"\nSet Padding 20\nSet Margin 10\nSet MarginFill \"#674EFF\"\nSet BorderRadius 8\n\n# Timing\nSet TypingSpeed 50ms\nSet Framerate 60\n\n# Environment\nSet Env \"TERM\" \"xterm-256color\"\nSet Env \"PS1\" \"$ \"\n\n# Window\nSet Shell \"bash\"\nSet WindowBar Colorful\nSet WindowBarSize 40\n```\n\n## Action Commands\n\n### Type\n\nTypes text into the terminal:\n\n```tape\nType \"echo 'Hello World'\"\nType@50ms \"slower typing\"\n```\n\n### Enter\n\nSends Enter key (execute command):\n\n```tape\nEnter\n```\n\n### Sleep\n\nPause for duration:\n\n```tape\nSleep 500ms\nSleep 2s\n```\n\n### Key Combinations\n\n```tape\nCtrl+C\nCtrl+D\nCtrl+L\nEscape\nTab\nBackspace\nUp\nDown\nLeft\nRight\nSpace\n```\n\n### Screenshot\n\nCapture a still frame:\n\n```tape\nScreenshot output.png\n```\n\n### Hide/Show\n\nControl visibility of actions:\n\n```tape\nHide\nType \"secret setup commands\"\nEnter\nShow\n```\n\n## Best Practices\n\n### Echo vs Commands\n\n**NEVER use `echo` to simulate or replace real command output.** Echo should only be used for:\n\n- Printing explanatory messages or headers\n- Simple text output demonstrations\n- Comments that need to appear in the terminal\n\n**ALWAYS prefer actual commands** that demonstrate functionality:\n\n```tape\n# BAD: Simulating output with echo\nType \"echo 'tool-a, tool-b, tool-c'\"\nEnter\n\n# GOOD: Using the actual command\nType \"my-cli --list-tools\"\nEnter\n```\n\nIf a command doesn't exist to show what you need, consider:\n1. Adding a flag or subcommand to the CLI being demonstrated\n2. Using the actual data source (file, API, etc.)\n3. Rethinking what the demo should show\n\n**Rationale**: Tutorials should demonstrate real functionality. Echoing data teaches users nothing about the actual tool and may become stale as the tool evolves.\n\n### MCP Tool Demonstrations\n\nWhen demonstrating MCP (Model Context Protocol) functionality, show how tools are used within the host environment (e.g., Claude Code) rather than calling CLI equivalents:\n\n```tape\n# POOR: Using CLI instead of MCP\nType \"skrills metrics\"\n\n# BETTER: Explain MCP tool usage\nType \"# In Claude Code, ask: 'Show me skill statistics'\"\nType \"# Claude calls the skill-metrics MCP tool automatically\"\n```\n\n## Advanced Features\n\n### Split Panes\n\nCreate multi-pane layouts:\n\n```tape\nSplit\nType@left \"echo 'Left pane'\"\nEnter@left\nType@right \"echo 'Right pane'\"\nEnter@right\n```\n\n### Source\n\nInclude other tape files:\n\n```tape\nSource common-setup.tape\n```\n\n### R"},{"path":"skill-card.md","content":"## Description:\n\nGenerates terminal recordings using VHS tape scripts and produces GIF outputs.\n\nThis skill is ready for commercial/non-commercial use.\n\n## Publisher:\n\n[athola](https://clawhub.ai/user/athola)\n\n### License/Terms of Use:\n\nMIT-0\n\n## Use Case:\n\nDevelopers and documentation authors use this skill to validate VHS tape files, run terminal recording workflows, and produce GIF demos for CLI documentation and tutorials.\n\n### Deployment Geography for Use:\n\nGlobal\n\n## Known Risks and Mitigations:\n\nRisk: VHS tape files can execute terminal commands and include other Source files.\n\nMitigation: Review each tape and included Source file before running it, and avoid untrusted tapes.\n\nRisk: Terminal recordings can expose secrets, environment values, or sensitive command output.\n\nMitigation: Use disposable demo projects where practical and sanitize terminal output before sharing recordings.\n\nRisk: Using the publish option can make recordings public.\n\nMitigation: Use --publish only for recordings that are intended to be publicly accessible.\n\nRisk: Mutable install examples can change the installed tool behavior over time.\n\nMitigation: Review the toolchain before use and prefer pinned dependency versions for repeatable production workflows.\n\n## Reference(s):\n\n- [ClawHub skill page](https://clawhub.ai/athola/skills/nm-scry-vhs-recording)\n- [Project homepage](https://github.com/athola/claude-night-market/tree/master/plugins/scry)\n- [VHS execution guide](modules/execution.md)\n- [VHS tape syntax reference](modules/tape-syntax.md)\n\n## Skill Output:\n\n**Output Type(s):** [shell commands, guidance, files]\n\n**Output Format:** [Markdown guidance with bash and tape code blocks]\n\n**Output Parameters:** [1D]\n\n**Other Properties Related to Output:** [Produces or verifies GIF outputs from VHS tape execution when the required local tools are installed.]\n\n## Skill Version(s):\n\n1.9.19 (source: server release evidence;
