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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00000 | $0.00681 |
| Opus 5.5 | $0.00000 | $0.00272 |
| Sonnet 5.5 | $0.00000 | $0.00136 |
| Haiku 4.5 | $0.00000 | $0.00068 |
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 10d 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.
How it starts
The opening of the file, as written. The whole thing — 40 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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
- The design system is locked and mandatory. Follow
.cursor/docs/design-system.mdas written, including §House language (direction C). Never add or change a token, species, size, radius, shadow, ink step or house-language rule unless the maintainer asked for that exact change in this chat. Updating a catalog row to match approved code is the only routine edit. Never editglobals.scsstheme blocks or tokens on your own. See §Change protocol (locked). - Tokens only. daisyUI semantic classes (
base-*,primary,*-content, status colors) orvar(--…)tokens — never raw Tailwind palette classes or hex outsideglobals.scssand 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-xlvia the canonical exports (popoverPanelClassName,contextMenuPanelClassName,modalPanelClassName); SCSS panels useborder-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, neverbg-base-200directly. - Shape scale = the daisyUI tokens (
--radius-selector8px ·--radius-field8px ·--radius-box10px — maintainer taste is 8–10px, tuned ONLY in the theme blocks). Surfaces consumerounded-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.
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 (95 stars, last pushed yesterday), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 681 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.
