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 | $0.00036 | $0.00249 |
| Opus 5 | $0.00018 | $0.00125 |
| Sonnet 5 | $0.00007 | $0.00050 |
| Haiku 4.5 | $0.00004 | $0.00025 |
Grade A, and why
design-stack 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 2d 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.
What it actually says
Design stack
Read premium-ui-craft every design turn. Then read one winner. Do not load all five.
| Work | Winner (also Read) |
|---|---|
| In-app product, shadcn dashboard, sidebar, couple/app UX | premium-ui-craft only |
| New marketing / landing / campaign page | landing-page-design |
| Audit/polish of an existing site or app | redesign-existing-projects |
| New chrome (rail, dock, shell) and you need live examples | ux-web-research after premium-ui-craft |
Paths: ~/.cursor/skills/<name>/SKILL.md.
Never Scandinavian, Nordic, Japandi, or hygge (no parchment, oatmeal, linen, sage-cream, pale wood). Elaya marketing (Geist, 700ms, Phosphor, island nav) does not override a locked product theme unless Mario is shipping a landing page.
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.

design-stack is a skill published in the GitHub repository kleosr/kleosrules (2 stars, last pushed 3d ago), licensed MIT. It adds 36 tokens to every session and 249 once invoked, about $0.0002 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.
