Getting started
Create a packed .K2F. Two paths: ask an agent, or write the JSON and pack it yourself.
To look at a file first, open the Playground or a sample in the Gallery.
Use an agent
npx skills add suzheng/k2f --skill k2f
pip install k2f
Works with Cursor, Claude Code, Codex, and other agents that support npx skills. pip install k2f puts the CLI on PATH; the skill scripts call it. If npx skills is not available, copy skills/core/k2f into your agent skills path as k2f/ (skills/README.md).
Then ask for a document, for example Write a one-page monthly report. The agent follows K2F Skill.
Write JSON yourself
1. Install the CLI
pip install k2f
Python 3.9+. This installs the k2f CLI and the Python SDK. Optional: cargo install k2f for a CLI without Python. Install @openk2f/k2f only when you embed the web viewer.
2. Get the skill folder
Starter package, catalog shapes, and helper scripts live in skills/core/k2f in k2f. Clone or copy that folder. Run the Python scripts from it (k2f must be on PATH).
3. Create a package
python scripts/init_package.py --workspace ./out/doc --title "Hello K2F" --page a4
Writes ./out/doc/source/ (empty content/root.json, starter theme, Roboto) and ./out/doc/tmp/ for preview PNGs.
4. Add content
Edit source/content/root.json. Keep id: "root" and paste catalog nodes into children. Do not replace root.json with a fragment. Start with ex_heading.json.
5. Pack and preview
python scripts/pack_verify.py ./out/doc/source -o ./out/doc/doc.K2F --render preview.png
Expect UNSIGNED. Open ./out/doc/tmp/preview.png. If the bottom third of the PNG is blank paper, you are not done — see visual check.
Export from the lock (optional):
k2f export-pdf ./out/doc/doc.K2F -o ./out/doc/doc.pdf
k2f export-pptx ./out/doc/doc.K2F -o ./out/doc/doc.pptx
k2f export-docx ./out/doc/doc.K2F -o ./out/doc/doc.docx
k2f export-idml ./out/doc/doc.K2F -o ./out/doc/doc
Guides: Export — PDF (fillable AcroForm), PowerPoint, Word, InDesign.
Existing file
k2f unpack existing.K2F -o ./out/doc/source
Do not pass --include-lock. Then the same edit / pack loop.
