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 | $0.00099 | $0.05112 |
| Opus 5 | $0.00049 | $0.02556 |
| Sonnet 5 | $0.00020 | $0.01022 |
| Haiku 4.5 | $0.00010 | $0.00511 |
Grade A, and why
dev-specialisms:frontend-vibes 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 — 469 lines — stays where its author put it; the contents beside it link to each section on GitHub.
This skill guides creation of distinctive, emotionally expressive frontend interfaces that balance technical precision with organic imperfection. Build React + TypeScript + Tailwind applications with faux-ASCII aesthetics, warm dark palettes, spring-based motion, and Anthropic-adjacent design sensibility.
Core Identity: Technical Precision Meets Organic Imperfection
The essence of this aesthetic lives in a productive tension: technical precision meets organic imperfection. The grid exists, but something breaks out of it. Type is clean, but rendered in dots or blocks. Palettes are restrained, but punctuated with jarring accents that make everything sing.
Expressive by Design: Create interfaces that make users feel something. Research shows expressive design helps users spot key elements 4x faster while inspiring emotional connection through strategic use of color, shape, size, motion, and containment. Balance emotional engagement with functional clarity—never sacrifice core usability for visual appeal.
The Feeling: Confidence of someone who knows what they're doing, expressed through restraint rather than excess. Technical but not cold. Modern but referencing history. Clean but with texture. Serious but with moments of play.
When to Use: Creative portfolios, developer tools, design systems, technical documentation, AI/LLM interfaces, anything wanting a distinctive voice. The constraint (faux-ASCII, warm palettes, spring motion) becomes the style.
Design Elements Framework
Map Material Design's five expressive elements to this distinctive aesthetic:
1. Color as Expression Strategic color use draws attention and conveys emotion. Prefer dark foundations (warm blacks with olive/brown undertones) punctuated by vibrant accents (electric orange, coral, neon green). The 90/10 rule: 90% restrained background, 10% vibrant accent doing all the emotional work.
2. Shape as Identity Distinctive forms create visual memory. Employ faux-ASCII shapes (block letterforms built from rectangles, pixelated figures, geometric patterns), scanline overlays, dot matrix compositions, and technical construction lines that reveal the design process.
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.

dev-specialisms:frontend-vibes is a skill published in the GitHub repository aaronbassett/agent-foundry (4 stars, last pushed 25d ago), licensed MIT. It adds 99 tokens to every session and 5,112 once invoked, about $0.0005 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 2026-08-31.
