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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00033 | $0.00260 |
| Opus 5.5 | $0.00013 | $0.00104 |
| Sonnet 5.5 | $0.00007 | $0.00052 |
| Haiku 4.5 | $0.00003 | $0.00026 |
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 1mo 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 the primary winner; supporting refs allowed when mixed product/marketing work needs both. Winner SKILL.md is the profile for this turn; SOURCE.md only when stuck. Premium is the product baseline; landing owns marketing; redesign audits then applies via the owning baseline. Do not force one aesthetic onto mixed work.
| Work | Primary winner |
|---|---|
| In-app product, shadcn, sidebar, couple/app UX | premium-ui-craft |
| New marketing / landing / campaign | landing-page-design |
| Audit/polish of an existing site or app | redesign-existing-projects |
| New chrome; need live examples | premium Research section |
Priority: 1) existing design system, 2) user needs + accessibility, 3) product/brand direction, 4) skill defaults. User brand and a11y win over house taste; bans are defaults, not vetoes. Required: reduced-motion behavior, keyboard access, focus visibility, contrast, and full interaction states.
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 (0 stars, last pushed 1mo ago), licensed MIT. It adds 33 tokens to every session and 260 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings.
