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 | $0.00108 | $0.01396 |
| Opus 5 | $0.00054 | $0.00698 |
| Sonnet 5 | $0.00022 | $0.00279 |
| Haiku 4.5 | $0.00011 | $0.00140 |
Grade A, and why
truestack-react-frontend 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 9d 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 — 78 lines — stays where its author put it; the contents beside it link to each section on GitHub.
truestack-react-frontend
A professional frontend is two things at once, and most generated UI fails one of them: it either looks templated (generic AI design) or it's pretty but badly built (needless re-renders, no accessibility, data waterfalls). This skill holds both bars — a distinctive, intentional design and clean, fast, accessible React.
Read project memory first (CLAUDE.md + .ai/memory/) for the design language, component
conventions, and stack. If the request is ambiguous, clarify first (same loop as
truestack-architecture-planning) — and for a new build, the planning/scoping step itself
belongs to truestack-architecture-planning; this skill picks up at implementation.
Ground framework claims in the project's actual dependencies (React version, compiler/bundler
config) and current docs — don't assert library behavior from recall.
1. Design with a point of view (don't ship AI slop)
Approach it as the design lead giving this product an identity that couldn't be mistaken for anyone else's. Ground every choice in the actual subject — its world, vocabulary, materials.
- Hero is a thesis — open with the most characteristic thing in the subject's world, not the template (big number + gradient accent).
- Typography carries personality — pair a characterful display face with a clean body face on an intentional scale; not the families you'd reach for on any project.
- One signature element — the single thing the page is remembered by. Spend your boldness there; keep everything else quiet.
- Structure encodes meaning — numbering / eyebrows / dividers only when they reflect something true (a real sequence), never decoration.
- Motion deliberately — one orchestrated moment beats scattered effects; respect
prefers-reduced-motion. Excess animation reads as AI-generated. - Avoid the AI-design clusters — cream-bg + serif + terracotta; near-black + acid accent; broadsheet hairline columns. Legitimate for some briefs, but defaults; don't spend a free axis on them.
What ships with it
2 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.

truestack-react-frontend is a skill published in the GitHub repository adtn0810/truestack (2 stars, last pushed 2mo ago), licensed MIT. It adds 108 tokens to every session and 1,396 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.
