# AGENTS.md - Agent Guidelines for malta-slides-marp
This project builds a presentation deck for Marp based on Markdown files.
## Agent Restrictions
- Agent NEVER runs commands on its own except changing files INSIDE THIS FOLDER, never any other then this
- Agent NEVER runs build commands or any automated processes without explicit user request, as the user is working in dev mode
## Critical File Protection: index.md
- `index.md` is the MAIN CONTENT FILE for the entire lecture series - treat with extreme care
- ALLOWED: Adding new slides, adjusting existing content, fixing typos, enhancing sections
- FORBIDDEN (without explicit permission): Deleting slides, removing sections, bulk replacements that remove content
- Before ANY deletion in index.md: ALWAYS ask user for confirmation and warn about what will be removed
- When in doubt, ADD rather than REPLACE - let the user decide what to remove
## Build Commands
- `npm run build` - Build slides from Markdown using Marp
- `npm run dev` - Start development server at http://localhost:8080
- `npm run watch` - Watch mode for live preview during development
- `npm run export:pdf` - Export slides to PDF format
- `npm run export:html` - Export slides to HTML format
## Test Commands
- `npm test` - Run all tests
- `npm run test:watch` - Run tests in watch mode
- `npm run test -- --testNamePattern="specific test name"` - Run single test
## Code Style Guidelines
### File Structure
- Use `slides/` directory for Markdown slide files
- Use `assets/` directory for images and media files
- Always address images as ./assets/filename.png, not assets/ or ../assets/
- Use `themes/` for custom Marp themes
- Use `build/` directory for generated output files (ignored by git)
### Naming Conventions
- Slide files: `index.md`, `additional-slides.md` (descriptive names)
- Images: `snake_case.jpg` or `kebab-case.jpg`
- Themes: `custom-theme.css`
### Markdown Style
- Use ATX-style headers (# ## ###)
- Consistent code block language identifiers
- Frontmatter for slide metadata (title, theme, etc.)
- Never include a final --- as it creates an unwanted empty slide
### Error Handling
- Validate Marp syntax before build
- Check for missing assets before export
- Log build errors with file paths and line numbers
### Git Workflow
- Commit slide changes with descriptive messages (ALWAYS lowercase)
- Use feature branches for major slide revisions
- Tag releases with version numbers
- NEVER add co-authoring lines or "Generated with" footers to commits
## Makefile Commands
- `make build` - Build slides from Markdown
- `make dev` - Start development server
- `make watch` - Watch for changes and rebuild
- `make pdf` - Export slides to PDF
- `make html` - Export slides to HTML
- `make clean` - Remove generated files
- `make install` - Install dependencies
- `make deploy` - Deploy slides to server

the Licensor hereby grants You a worldwide, royalty-free,
non-sublicensable, non-exclusive, irrevocable license to

Licensor waives and/or agrees not to assert any right or
authority to forbid You from making technical modifications
necessary to exercise the Licensed Rights, including
technical modifications necessary to circumvent Effective
Technological Measures. For purposes of this Public License,

under the conditions of the Adapter's License You apply.
c. No downstream restrictions. You may not offer or impose
any additional or different terms or conditions on, or
apply any Effective Technological Measures to, the
Licensed Material if doing so restricts exercise of the
Licensed Rights by any recipient of the
Licensed Material.

may be construed as permission to assert or imply that You
are, or that Your use of the Licensed Material is, connected
with, or sponsored, endorsed, or granted official status by,

extent necessary to allow You to exercise the Licensed
Rights, but not otherwise.
2. Patent and trademark rights are not licensed under this
Public License.
3. To the extent possible, the Licensor waives any right to
collect royalties from You for the exercise of the Licensed
Rights, whether directly or through a collecting society
under any voluntary or waivable statutory or compulsory
licensing scheme. In all other cases the Licensor expressly
reserves any right to collect such royalties.
Section 3 -- License Conditions.
Your exercise of the Licensed Rights is expressly made subject to the
following conditions.

context in which You Share Adapted Material.
3. You may not offer or impose any additional or different terms
or conditions on, or apply any Effective Technological
Measures to, Adapted Material that restrict exercise of the
rights granted under the Adapter's License You apply.
Section 4 -- Sui Generis Database Rights.
Where the Licensed Rights include Sui Generis Database Rights that
apply to Your use of the Licensed Material:
a. for the avoidance of doubt, Section 2(a)(1) grants You the right
to extract, reuse, reproduce, and Share all or a substantial
portion of the contents of the database;
b. if You include all or a substantial portion of the database
contents in a database in which You have Sui Generis Database
Rights, then the database in which You have Sui Generis Database

ANY KIND CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS,
IMPLIED, STATUTORY, OR OTHER. THIS INCLUDES, WITHOUT LIMITATION,
WARRANTIES OF TITLE, MERCHANTABILITY, FITNESS FOR A PARTICULAR
PURPOSE, NON-INFRINGEMENT, ABSENCE OF LATENT OR OTHER DEFECTS,
ACCURACY, OR THE PRESENCE OR ABSENCE OF ERRORS, WHETHER OR NOT
KNOWN OR DISCOVERABLE. WHERE DISCLAIMERS OF WARRANTIES ARE NOT
ALLOWED IN FULL OR IN PART, THIS DISCLAIMER MAY NOT APPLY TO YOU.
b. TO THE EXTENT POSSIBLE, IN NO EVENT WILL THE LICENSOR BE LIABLE
TO YOU ON ANY LEGAL THEORY (INCLUDING, WITHOUT LIMITATION,
NEGLIGENCE) OR OTHERWISE FOR ANY DIRECT, SPECIAL, INDIRECT,
INCIDENTAL, CONSEQUENTIAL, PUNITIVE, EXEMPLARY, OR OTHER LOSSES,
COSTS, EXPENSES, OR DAMAGES ARISING OUT OF THIS PUBLIC LICENSE OR
USE OF THE LICENSED MATERIAL, EVEN IF THE LICENSOR HAS BEEN
ADVISED OF THE POSSIBILITY OF SUCH LOSSES, COSTS, EXPENSES, OR
DAMAGES. WHERE A LIMITATION OF LIABILITY IS NOT ALLOWED IN FULL OR
IN PART, THIS LIMITATION MAY NOT APPLY TO YOU.
c. The disclaimer of warranties and limitation of liability provided
above shall be interpreted in a manner that, to the extent
possible, most closely approximates an absolute disclaimer and
waiver of all liability.
Section 6 -- Term and Termination.
a. This Public License applies for the term of the Copyright and
Similar Rights licensed here. However, if You fail to comply with
this Public License, then Your rights under this Public License
terminate automatically.
b. Where Your right to use the Licensed Material has terminated under
Section 6(a), it reinstates:
1. automatically as of the date the violation is cured, provided
it is cured within 30 days of Your discovery of the
violation; or
2. upon express reinstatement by the Licensor.
For the avoidance of doubt, this Section 6(b) does not affect any
right the Licensor may have to seek remedies for Your violations
of this Public License.
c. For the avoidance of doubt, the Licensor may also offer the
Licensed Material under separate terms or conditions or stop
distributing the Licensed Material at any time; however, doing so
will not terminate this Public License.
d. Sections 1, 5, 6, 7, and 8 survive termination of this Public
License.

shall not be interpreted to, reduce, limit, restrict, or impose
conditions on any use of the Licensed Material that could lawfully
be made without permission under this Public License.
b. To the extent possible, if any provision of this Public License is
deemed unenforceable, it shall be automatically reformed to the
minimum extent necessary to make it enforceable. If the provision
cannot be reformed, it shall be severed from this Public License
without affecting the enforceability of the remaining terms and
conditions.
c. No term or condition of this Public License will be waived and no
failure to comply consented to unless expressly agreed to by the

d. Nothing in this Public License constitutes or may be interpreted
as a limitation upon, or waiver of, any privileges and immunities
that apply to the Licensor or You, including from the legal
processes of any jurisdiction or authority.

## Über dieses Modul
> *Internettechnologien 1 – "Technische Grundlagen von IT-Projekten"*
Die Digitalisierung verändert die Prozesse und Tätigkeiten in allen Branchen. Sie hat neue Geschäftsmodelle ermöglicht und auch unseren Alltag stark verändert. Kaum ein Projekt in der Medienwelt kommt ohne digitale Technik aus – als Produkt, Kollaborationsplattform oder Marketing- und Verkaufsplattform.
**Ziel:** Technische Grundlagen verstehen, um mit Entwicklungsteams, Kunden und Projektpartnern auf Augenhöhe zusammenarbeiten zu können.

## Slides erstellen
### Basic Slide Structure
Slides are written in Markdown and separated by `---`:
```markdown
---
marp: true
theme: uncover
paginate: true
---
# Slide Title
Content here
---
# Next Slide
More content
```
### Frontmatter
Configure slide settings at the top:
```yaml
---
marp: true
theme: uncover
paginate: true
backgroundColor: #fff
title: My Presentation
---
```
### Themes
Use built-in themes:
- `default`
- `gaia`
- `uncover`
Or create custom themes in `themes/` directory.
### Images and Assets
Place images in `assets/` directory and reference them:
```markdown
![Alt text](assets/image.jpg)
```
## Custom Themes
Create custom themes in `themes/` directory:
```css
/* @theme custom-theme */
@import-theme "gaia";
section {
background-color: #f0f8ff;
color: #2c3e50;
}
h1 {
color: #3498db;
}
```
Apply custom theme in frontmatter:
```yaml
---
marp: true
theme: custom-theme
---
```
## Development Workflow
1. Edit slide files in `slides/` directory
2. Use `npm run dev` for live preview
3. Make changes and see updates automatically
4. Export final version with `npm run export:pdf`
## Makefile Commands
Alternative commands using Make:
```bash
make build # Build slides
make dev # Start development server
make pdf # Export to PDF
make html # Export to HTML
make watch # Watch for changes
make clean # Remove generated files
make deploy # Deploy slides to server
```
## Tips
- Use `---` to separate slides
- Frontmatter controls global settings
- Images should be in `assets/` directory
- Custom themes extend built-in themes
- PDF export requires Chrome/Chromium
## Troubleshooting
- **PDF export fails**: Ensure Chrome/Chromium is installed
- **Server not starting**: Check if port 8080 is available
- **Styles not applying**: Verify theme file paths
- **Images not loading**: Check relative paths from slides directory
## Contributing
1. Follow the file structure conventions
2. Use numbered prefixes for slide files
3. Test builds before committing
4. Keep commit messages lowercase and descriptive
