A guide for choosing and applying one consistent visual direction to a user interface, terminal tool, command-line program, or desktop app. It covers choices such as colors, type, spacing, density, and motion.

Use it when starting UI work, defining design tokens, or correcting an interface that looks like default framework output.

It helps replace generic or inconsistent interface decisions with a deliberate set of rules. It also checks that the direction fits the named runtime and different surfaces.

NVIDIA SkillSpector warn 7 Sept 2026

SkillSpector: 1 finding, up to medium

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

medium Excessive Agency · line 83
Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.

Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00046	$0.02402
Opus 5	$0.00023	$0.01201
Sonnet 5	$0.00009	$0.00480
Haiku 4.5	$0.00005	$0.00240

Security

Grade A, and why

design 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 3d 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.

Design

Contract

Field	Bound contract
Trigger	Starting UI work, defining palettes or design tokens, correcting AI-generic, vibe-coded, or default-framework design, or persisting an approved design system to DESIGN.md.
Authority	Reversible local: writes only local UI direction, token, and implementation artifacts; persist mode also writes DESIGN.md, CLAUDE.md pointers, and preview artifacts. Rollback is version control. No remote mutation.
Side effect	Local writes to the picked mode's artifacts only, bounded to the current project directory.
Done	Implement mode: one defensible direction is implemented consistently across palette, typography, spacing, density, and motion, and the audit passes clean. Persist mode: an approved design system is persisted in DESIGN.md.

Inputs

Mode: implement (direction and token implementation) or persist (propose, preview, and persist an approved system to DESIGN.md). Required; default implement when unstated.
The surface being designed (landing, dashboard, settings, docs, one-screen tool, TUI, CLI, desktop app). Required.
The runtime or framework in use (vanilla CSS/HTML, React/Tailwind/shadcn, Bubble Tea/Ratatui/Textual, clap/cobra/cmdliner/typer, Tauri/Slint/egui/Iced, Qt/QML). Required before step 6 in implement mode.
Primary user and density target. Required for framing; state assumptions if not supplied.
Existing project context (PRD, brand brief, design tokens, component library, an existing DESIGN.md to extend). Optional; load when present.
Persist mode only: user approval is the in-loop gate. No design system is persisted until the user approves it.

Procedure

Direction precedes tokens; tokens precede code. The picked direction is the contract. Restraint is the default; reach for decoration only when a named surface goal demands it. Balance, not maximalism, not minimalism.

Frame the surface. Identify register first: brand (marketing, landing, campaign, long-form, portfolio; design IS the product) or product (app UI, admin, dashboard, tool; design SERVES the product). Detection rule, first match wins: (a) cue in the task ("landing page" / "campaign hero" → brand; "dashboard" / "settings panel" → product); (b) surface in focus or route segment (/marketing/* vs /app/*); (c) register field in project context. Then capture surface, primary user, density target, and motion budget in ms. Write one sentence of physical scene (who, where, ambient light, mood) that forces the dark/light decision; category names alone do not force the answer. Mode persist: read any existing DESIGN.md, tokens, and brand guidance first; name missing context rather than inventing it. Done when: register is named, the four framing fields are captured, and the dark/light sentence is written.

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 is a skill published in the GitHub repository OutlineDriven/outline-driven-development (52 stars, last pushed 3d ago), licensed Apache-2.0. It adds 46 tokens to every session and 2,402 once invoked, about $0.0002 per session on Opus 5. 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 2026-09-03.
