codegen-html skillA
codegen-html is agent-read markdown (skill) from initializ/forge: Scaffold and iterate on standalone Preact + HTM applications with zero build dependencies.
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Codegen HTML Skill
Scaffold and iteratively build standalone HTML applications using Preact + HTM via CDN. Zero local dependencies — no Node.js, no npm, no build step. Just open the HTML file in a browser.
## Quick Start
```bash
# Scaffold a single-file app
./scripts/codegen-html-scaffold.sh '{"project_name": "my-app", "output_dir": "/tmp/my-app", "mode": "single-file"}'
# Scaffold a multi-file app
./scripts/codegen-html-scaffold.sh '{"project_name": "my-app", "output_dir": "/tmp/my-app", "mode": "multi-file"}'
# Read a file or list the project
./scripts/codegen-html-read.sh '{"project_dir": "/tmp/my-app", "file_path": "."}'
# Write/update a file
./scripts/codegen-html-write.sh '{"project_dir": "/tmp/my-app", "file_path": "index.html", "content": "..."}'
```
## CRITICAL: Scaffold Conventions (DO NOT VIOLATE)
These rules prevent runtime errors:
1. **Use `class` (not `className`)** — HTM maps directly to DOM attributes
2. **Use Tailwind CSS utility classes** for all styling (loaded via CDN in `index.html`)
3. **Do NOT create `<style>` blocks or `.css` files** — use Tailwind classes instead
4. **Keep Preact/HTM imports unchanged** — do not change CDN URLs or versions
…Read the whole file at its exact version.
How to install
mdr add initializ/forge/codegen-html@git:20260304.ef09c7bmdr add initializ/forge/codegen-html@sha256:0945dcc769ff1affPin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
