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.

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 | $0.00047 | $0.00892 |
| Opus 5 | $0.00023 | $0.00446 |
| Sonnet 5 | $0.00009 | $0.00178 |
| Haiku 4.5 | $0.00005 | $0.00089 |
Grade A, and why
frontend-design-direction 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 yesterday.
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.
This is a copy
88% identical to frontend-design-direction — 28 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 94 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Frontend Design Direction
Use this skill when the work is not just making UI function, but making it feel purposeful, polished, and appropriate to the product domain.
Source: salvaged from stale community PR #1659 by linus707.
Note: ECC intentionally does not rebundle the canonical Anthropic
frontend-design skill. Install that from anthropics/skills when you want the
official upstream skill. This skill is the ECC-specific design-direction salvage
of the useful local guidance from #1659.
When to Use
- The user asks to build a web page, app, dashboard, artifact, component, or UI.
- The user asks to make an interface more polished, distinctive, beautiful, or less generic.
- The implementation needs visual hierarchy, typography, color, motion, layout, and interaction choices.
- The current UI works but reads as flat, generic, templated, or mismatched to the audience.
Design Direction
Before coding, choose a specific direction:
- Purpose: what job does the interface do?
- Audience: who repeats this workflow, and what do they need to scan first?
- Tone: utilitarian, editorial, playful, industrial, refined, technical, maximal, minimal, dense, calm, or another explicit direction.
- Memorable detail: one design idea that makes the result feel intentional.
- Constraints: framework, accessibility, performance, responsiveness, and existing design system.
Match the direction to the domain. A SaaS operations tool should usually be dense, quiet, and scannable. A portfolio, launch page, game, or editorial piece can be more expressive. Do not force a landing-page composition onto a tool that needs repeated daily use.
Implementation Guidance
- Build the actual usable experience as the first screen unless the user explicitly asks for marketing copy.
- Use existing project components, tokens, icon libraries, and routing patterns before introducing a new visual system.
- Use real or generated visual assets when the interface depends on images, products, places, people, gameplay, charts, or inspectable media.
- Prefer contextual typography and spacing over generic oversized hero text.
- Keep palettes multi-dimensional: avoid a UI dominated by one hue family.
- Use CSS variables or existing design tokens so the direction remains coherent across states.
- Design responsive constraints explicitly: grids, aspect ratios, min/max sizes, stable toolbars, and fixed-format controls should not shift when labels or hover states appear.
- Use motion sparingly but deliberately. Prefer high-signal transitions that clarify state over decorative animation.
- Verify text fit on mobile and desktop. Long labels must wrap or resize cleanly rather than overflowing.
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.

frontend-design-direction is a skill published in the GitHub repository unrealandychan/clean-code-skill (6 stars, last pushed 2d ago), licensed MIT. It adds 47 tokens to every session and 892 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 88% identical to frontend-design-direction, differing in 28 lines, and is treated as a copy.
