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 | $0.00135 | $0.02383 |
| Opus 5 | $0.00068 | $0.01192 |
| Sonnet 5 | $0.00027 | $0.00477 |
| Haiku 4.5 | $0.00014 | $0.00238 |
Grade A, and why
vite-core-architecture 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 12d 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.

Quick Reference
Two-Mode Architecture
Vite operates as two completely different systems depending on context:
| Aspect | Dev Server (vite) |
Production Build (vite build) |
|---|---|---|
| Strategy | Native ESM, no bundling | Full bundle via Rolldown/Rollup |
| Module delivery | Individual files over HTTP | Optimized chunks |
| Transform tool (v8) | Oxc | Oxc |
| Transform tool (v5-7) | esbuild | esbuild |
| Bundler (v8) | None (native ESM) | Rolldown |
| Bundler (v5-7) | None (native ESM) | Rollup |
| Speed priority | Instant startup + HMR | Optimized output size |
| Browser target | esnext | baseline-widely-available |
Internal Tools Evolution
| Version | Dev Transform | Dev Pre-bundling | Production Bundler | CSS Minification | JS Minifier |
|---|---|---|---|---|---|
| Vite 5 | esbuild | esbuild | Rollup | esbuild | esbuild |
| Vite 6 | esbuild | esbuild | Rollup | esbuild/lightningcss | esbuild |
| Vite 7 | esbuild | esbuild | Rollup | esbuild/lightningcss | esbuild |
| Vite 8 | Oxc | Rolldown | Rolldown | Lightning CSS | Oxc (30-90x faster than Terser) |
Node.js Requirements
| Vite Version | Minimum Node.js |
|---|---|
| v5, v6 | 18+ |
| v7+ | 20.19+ or 22.12+ |
Browser Support Targets
| Context | Target | Meaning |
|---|---|---|
| Dev server | esnext | Latest JavaScript/CSS features, no transpilation |
| Production (v8 default) | baseline-widely-available | Chrome 111, Edge 111, Firefox 114, Safari 16.4 |
| Production (v7 default) | baseline-widely-available | Chrome 107, Edge 107, Firefox 104, Safari 16.0 |
| Legacy browsers | @vitejs/plugin-legacy |

Critical Warnings
NEVER set envPrefix to '' -- this exposes ALL environment variables (including secrets like DB_PASSWORD) to client-side code.
What ships with it
3 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.

vite-core-architecture is a skill published in the GitHub repository OpenAEC-Foundation/OpenAEC-Workspace-Composer (5 stars, last pushed 5mo ago), licensed MIT. It adds 135 tokens to every session and 2,383 once invoked, about $0.0007 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.
