design-system

A set of binding rules for the Massing web application's visual design system, including colors, spacing, shapes, shadows, panels, and motion.

In plain words
What is it for?
Use it before changing UI, themes, or styling to choose approved design tokens, surface treatments, panel patterns, and behavior for light and dark modes.
Why use it?
It keeps new interface work consistent and avoids styling choices that conflict with the project's shared visual and interaction rules.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Made for: Cursor.

Per session 0 Nothing until a file matches its globs; then the whole rule loads.
When invoked 557 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

design-system scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Design System

Authoritative source: .cursor/docs/design-system.md. Read it before any UI/theme/styling work; the design-system skill in .cursor/skills/ is the working protocol. Behavioral invariants (pad geometry, motion wiring, scrims, sheet systems) live in apps/webapp/CLAUDE.md, which loads automatically under apps/webapp/. AGENTS.md keeps only §UI And Theme.

Cardinal rules

  • Tokens only. daisyUI semantic classes (base-*, primary, *-content, status colors) or var(--…) tokens — never raw Tailwind palette classes or hex outside globals.scss and the brand allowlist (social/platform/logo colors; media-anchored overlays stay black/white).
  • One floating language. Anchored surfaces = rounded-box border-base-300 bg-base-100 shadow-xl via the canonical exports (popoverPanelClassName, contextMenuPanelClassName, modalPanelClassName); SCSS panels use border-radius: var(--radius-box) + var(--shadow-overlay).
  • Docked surfaces are flat in light (borders, no shadows); dark lift comes from tokens only. The workspace floor is --pad-well, never bg-base-200 directly.
  • Shape scale = the daisyUI tokens (--radius-selector 8px · --radius-field 8px · --radius-box 10px — maintainer taste is 8–10px, tuned ONLY in the theme blocks). Surfaces consume rounded-selector|field|box/rounded-full, never Tailwind literal radius classes; micro px radii (2–4px) live only in prose/editor decorations.
  • States follow the recipes in the doc (is-active = primary-10% bg + primary ink; hover = base-200; focus = focus-visible:ring-2 ring-primary; unread = error badge).
  • Verify in the browser, light + dark, desktop + mobile, before calling visual work done.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

design-system is a cursor rule published in the GitHub repository docs-plus/docs.plus (88 stars, last pushed 4d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 557 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
