The Lossless Group's theme and mode architecture — two-tier token system, three-mode contract (light/dark/vibrant), theme.css organization, and design system conventions. Use when setting up themes/modes for any Astro Knots site, debugging mode toggles, working with CSS tokens, or when the user mentions "vibrant mode", "two-tier tokens", "theme.css", or design system patterns.
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
# Theme System The Lossless Group's firm-wide conventions for theme architecture, visual modes, and design token systems. **Status:** Initial scaffold (May 2026) — actively developing from astro-knots patterns. ## When to use this skill - Setting up theme/mode architecture for a new site - Debugging mode toggle issues (light/dark/vibrant not working) - Implementing two-tier token systems - Deciding between `theme.css` vs `global.css` organization - Creating `/brand-kit` or `/design-system` reference pages - User mentions "vibrant mode", "two-tier tokens", "mode switcher", "theme architecture" ## Core Principles (WIP) ### 1. Three-Mode Contract (Not Two) Every Lossless site ships with **three modes**, not two: - **Light** — clean, minimal, high readability - **Dark** — code-editor feel, moderate intensity - **Vibrant** — neon energy, loud gradients, glassmorphic surfaces **Why three?** Stakeholder management. Nerds pick dark, traditionalists pick light, design-forward stakeholders pick vibrant. The toggle ends the "which mode" argument before it starts. …

How to install
mdr add lossless-group/lossless-agent-skills/theme-system@sha256:f11088d310ae5b6bThe line at the top of this page pins the label git:20261006.6e47832, 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.
