llm.log: Skill for Claude Code

.agents/skills/frontend-design/SKILL.md

frontend-design is a skill for Claude Code, Codex from lanesket/llm.log. It costs 47 tokens per session (1,990 once invoked), scanned A, a copy of frontend-design, MIT.

A workflow for creating polished web pages, components, posters, and applications. It requires knowing the intended audience, use cases, and visual tone before design work begins.

In plain words
What is it for?
Use it when building frontend interfaces or other visual web artifacts. It helps shape the layout, appearance, and implementation around a confirmed design context.
Why use it?
It reduces generic-looking interfaces by grounding design choices in the product and its users. It also encourages production-ready code and attention to visual detail.

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents).

This is lanesket/llm.log's own configuration. It tells Claude Code and Codex how to work on llm.log itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything llm.log configures →

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

frontend-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 8d 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 — 147 lines — stays where its author put it; the contents beside it link to each section on GitHub.

This skill guides creation of distinctive, production-grade frontend interfaces that avoid generic "AI slop" aesthetics. Implement real working code with exceptional attention to aesthetic details and creative choices.

Context Gathering Protocol

Design skills produce generic output without project context. You MUST have confirmed design context before doing any design work.

Required context — every design skill needs at minimum:

  • Target audience: Who uses this product and in what context?
  • Use cases: What jobs are they trying to get done?
  • Brand personality/tone: How should the interface feel?

Individual skills may require additional context — check the skill's preparation section for specifics.

CRITICAL: You cannot infer this context by reading the codebase. Code tells you what was built, not who it's for or what it should feel like. Only the creator can provide this context.

Gathering order:

  1. Check current instructions (instant): If your loaded instructions already contain a Design Context section, proceed immediately.
  2. Check .impeccable.md (fast): If not in instructions, read .impeccable.md from the project root. If it exists and contains the required context, proceed.
  3. Run teach-impeccable (REQUIRED): If neither source has context, you MUST run the teach-impeccable skill NOW before doing anything else. Do NOT skip this step. Do NOT attempt to infer context from the codebase instead.

Design Direction

Commit to a BOLD aesthetic direction:

  • Purpose: What problem does this interface solve? Who uses it?
  • Tone: Pick an extreme: brutally minimal, maximalist chaos, retro-futuristic, organic/natural, luxury/refined, playful/toy-like, editorial/magazine, brutalist/raw, art deco/geometric, soft/pastel, industrial/utilitarian, etc. There are so many flavors to choose from. Use these for inspiration but design one that is true to the aesthetic direction.
  • Constraints: Technical requirements (framework, performance, accessibility).
  • Differentiation: What makes this UNFORGETTABLE? What's the one thing someone will remember?

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.
