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 | $0.00019 | $0.01089 |
| Opus 5 | $0.00010 | $0.00544 |
| Sonnet 5 | $0.00004 | $0.00218 |
| Haiku 4.5 | $0.00002 | $0.00109 |
Grade A, and why
frontend-design-fix 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 6d 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.

Frontend Design Fix Skill
Overview
This orchestrator skill diagnoses generic design patterns and applies targeted aesthetic upgrades across five design dimensions. Fixes are tech-agnostic (principles) but reference framework-specific implementation skills.
The 5 Dimensions:
- Typography – Replace generic fonts, fix weight hierarchies, aggressive size jumps
- Color & Theme – Remove predictable palettes, introduce CSS variables, add dominant + accent strategy
- Motion – Add orchestrated page loads, staggered reveals, hover surprises
- Spatial Composition – Break centered layouts, introduce asymmetry, adjust spacing strategy
- Backgrounds & Details – Layer gradients, add geometric patterns, create atmospheric depth
Quick Diagnosis
"What's wrong with my design?"
It looks like a template → See ./sub-skills/audit.md
Font choices feel default → See ./sub-skills/typography-fixes.md
Color palette is predictable → See ./sub-skills/color-fixes.md
Everything's static and boring → See ./sub-skills/motion-fixes.md
Layout is centered and uniform → See ./sub-skills/spatial-fixes.md
Backgrounds are flat/plain → See ./sub-skills/background-fixes.md
5-Phase Fix Process
Phase 1: Audit
Identify generic elements, score anti-patterns, assess brand context
→ See ./sub-skills/audit.md
Phase 2: Assess Brand & Context
Understand emotional intent, target audience, competitive differentiation
Phase 3: Apply Dimension-Based Fixes
- Typography fixes (typeface, weights, size jumps)
- Color fixes (palette strategy, CSS variables, accents)
- Motion fixes (orchestration, scroll triggers, hover)
- Spatial fixes (asymmetry, overlap, diagonal flow)
- Background fixes (gradients, patterns, depth)
→ See specific sub-skills below
Phase 4: Validate Improvements
- Visual hierarchy strengthened?
- Brand personality evident?
- Accessibility maintained (WCAG AA+)?
- Performance acceptable?
What ships with it
7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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-fix is a skill published in the GitHub repository matteocervelli/llms (25 stars, last pushed 3mo ago), licensed MIT. It adds 19 tokens to every session and 1,089 once invoked, about $0.0001 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.
