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 | $0.00016 | $0.00715 |
| Opus 5 | $0.00008 | $0.00358 |
| Sonnet 5 | $0.00003 | $0.00143 |
| Haiku 4.5 | $0.00002 | $0.00072 |
Grade A, and why
atomic-design 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

Atomic Design — Quick Reference
Level Decision Table
| Level | Folder | Composes | Has State | Fetches Data | Real Content |
|---|---|---|---|---|---|
| Atom | components/ui/ |
Nothing | No | No | No |
| Molecule | components/molecules/ |
2–5 atoms | Maybe | No | No |
| Organism | components/organisms/ |
Molecules + atoms | Yes | Yes | No |
| Template | components/templates/ |
Organisms | No | No | Placeholder |
| Page | (route file) | Templates | No | Yes | Real |
If you can't decide: IF it composes nothing → atom. IF it composes ≤5 atoms → molecule. IF it manages state or fetches data → organism. IF it's a full layout skeleton → template.
Composition Rules
- Atoms: no
composesSpecs, no imports of other atoms - Molecules: 2–5 atom imports, no data fetching, may have internal open/closed state
- Organisms: own breakpoints, document composition in spec
- Templates: CSS Grid or Flexbox only, must match Figma page spec
- Pages: handle all data states — loading, empty, error, populated

Design Tokens
Global tokens (--blue-500, --space-4)
→ Alias tokens (--color-primary, --spacing-component)
→ Component tokens (--button-bg, --card-radius)
Override alias tokens per theme: :root, .dark, .brand-b.
Accessibility by Level
| Level | Required |
|---|---|
| Atom | ARIA role, keyboard focus, contrast, label |
| Molecule | Focus management, error announcements |
| Organism | Landmark roles, skip links, focus trapping |
| Template | Page title, heading hierarchy, main landmark |
| Page | Full WCAG 2.1 AA |
Naming
| Element | Convention | Example |
|---|---|---|
| Components | PascalCase | MetricCard |
| Props | camelCase | isLoading |
| CSS classes | kebab-case | text-muted-foreground |
| Constants | UPPER_SNAKE | MAX_RETRY_COUNT |
| Tokens | path/style | color/primary/500 |
What ships with it
1 file 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.

atomic-design is a skill published in the GitHub repository memi-design/design-skills (7 stars, last pushed 1mo ago), licensed MIT. It adds 16 tokens to every session and 715 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 2026-08-31.
