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 | $0.00138 | $0.05814 |
| Opus 5 | $0.00069 | $0.02907 |
| Sonnet 5 | $0.00028 | $0.01163 |
| Haiku 4.5 | $0.00014 | $0.00581 |
Grade C, and why
magento2-hyva-dev scanned grade C with 2 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 6d 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.

Magento 2 Hyvä Developer
Hyvä is a modern Magento 2 frontend framework with dramatically simplified JavaScript and CSS. This skill covers Hyvä-specific patterns.
Related Skills
REQUIRED BACKGROUND: Load magento2-dev-core first — it defines the PHP/backend patterns (DI, escaping, repositories) this skill assumes for any ViewModel or backend code behind a Hyvä template.
Hyvä and Luma (magento2-frontend-dev) are mutually exclusive theme stacks — check the theme's theme.xml parent (Hyva/default/Hyva/reset vs Magento/blank) and composer.json for hyva-themes/* packages before assuming either applies. Hybrid projects (e.g. dual-stack) keep both: app/design/frontend/<Vendor>/hyva_* → this skill, app/design/frontend/<Vendor>/luma_child → magento2-frontend-dev. Pair with govard-magento for the container/CLI side.
Detect the project's actual setup first
On DSH: call
hyva_theme_inspect {classes:["<class-from-diff>"]}— returns{themes[],tailwind:{major,...},hyvaPackages[]}grounded from theme.xml + package.json + tailwind.config/hyva.config + composer.lock. If any field null, check notes and downgrade to a question. Otherwise: read theme.xml parent, /web/tailwind/package.json, tailwind.config.js or tailwind-source.css+hyva.config.json, and composer.lock — verify, don't memorize table (verified 2026-08-26).
Hyvä/Tailwind conventions vary a lot by project age — check before applying a pattern:
- Tailwind version: v4 uses CSS-based config and
hyva.config.jsondesign tokens; v2/v3 usetailwind.config.js. Checkweb/tailwind/package.json. - CSP build:
Hyva/default-cspvs the plainHyva/default/Hyva/resetparent intheme.xml. Applying CSP-only nonce patterns to a non-CSP theme (or vice versa) wastes effort. - Parent theme:
Hyva/reset(built from scratch) vsHyva/default(full starter) changes how much markup/CSS already exists to extend rather than rewrite.
Hyvä vs Luma Comparison
| Aspect | Luma | Hyvä |
|---|---|---|
| JavaScript | ~200 resources (RequireJS/Knockout) | 2 resources (Alpine.js) |
| CSS | LESS-based | Tailwind CSS |
| Bundle Size | 500KB+ | <50KB |
| Core Web Vitals | Challenging | Optimized |
| Learning Curve | Steep | Gentle |
| Maintenance | Complex | Simple |
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.

It adds 138 tokens to every session and 5,814 once invoked, about $0.0007 per session on Opus 5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
