k2f.dev Observed source

Editorial interest 82/100 Selection signal · not a rating of the site

K2F is a proposed document format that separates semantic content from styling and locks the rendered result into a portable file.

Landing page captured for the 2026-09-01 issue.

Field notes

K2F models documents as a semantic tree plus a separate theme, with examples covering headings, body text, warnings, typography, and color palettes. Its advertised package includes manifest.json, content/root.json, styles/theme.json, and a generated .K2F.lock file intended to preserve rendering. The homepage also exposes an npx skill installation path for Cursor, Claude Code, Codex, and similar agents, while labeling the project v0.1 under an Apache 2.0 license.
