Delivers a static Hello World HTML demo page with bookmarklet. Use when user requests the hello demo, hello world demo, or demo page.
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
## Delivery Instructions When triggered: 1. Copy the asset to outputs: ```bash cp assets/hello-demo.html /mnt/user-data/outputs/ ``` 2. Provide the computer link: ``` [View hello-demo.html](computer:///mnt/user-data/outputs/hello-demo.html) ``` 3. Add one-line description: "Interactive HTML demo with bookmarklet showing token-efficient artifact delivery." **DO NOT**: - Generate HTML from scratch - Explain the file contents in detail - Add verbose commentary The asset contains a complete, styled HTML page with: - Bookmarklet demonstration - Usage instructions - Token efficiency explanation **Token efficiency**: This pattern saves ~500 tokens vs. generating explanatory text each time.
Read the whole file at its exact version.
How to install
mdr add oaustegard/claude-skills/hello-demo@sha256:c6b299796234f95aThe line at the top of this page pins the label v1.0.4, 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.
