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 | $0.00051 | $0.02153 |
| Opus 5 | $0.00026 | $0.01077 |
| Sonnet 5 | $0.00010 | $0.00431 |
| Haiku 4.5 | $0.00005 | $0.00215 |
Grade A, and why
static-assets scanned grade A with 1 finding 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 4d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Cloudflare Static Assets
Serve static files, single-page applications (SPAs), and build hybrid Workers that combine API routes with frontend hosting.
FIRST: Project Setup
Static Assets require a public/ directory and configuration in wrangler.jsonc:
# Create public directory for your build output
mkdir public
# Add your static files
echo "<h1>Hello World</h1>" > public/index.html
When to Use
| Use Case | Description |
|---|---|
| Single-Page Applications | React, Vue, Angular apps with client-side routing |
| Static Sites | HTML/CSS/JS sites, generated static content |
| Hybrid Apps | Worker API routes + frontend in one deployment |
| Framework Integration | Next.js, Vite, Remix build outputs |
Quick Reference
| Task | Configuration |
|---|---|
| Basic static hosting | "assets": { "directory": "./public/" } |
| SPA routing (404 → index) | "not_found_handling": "single-page-application" |
| Custom 404 page | "not_found_handling": "404-page" |
| Custom binding name | "binding": "ASSETS" (default) |
| Access in Worker | env.ASSETS.fetch(request) |
wrangler.jsonc Configuration
Basic Static Hosting
{
"name": "my-static-site",

SPA with Custom 404 Handling

}
not_found_handling options:
"single-page-application"- Routes all 404s to/index.html(default for SPAs)"404-page"- Serves/404.htmlfor missing files"none"- Returns standard 404 responses
Hybrid Worker with Static Assets
Combine API routes with static file serving in a single Worker:
// src/index.ts
interface Env {
ASSETS: Fetcher;
}
export default {
fetch(request, env) {
const url = new URL(request.url);
// Handle API routes in the Worker
if (url.pathname.startsWith("/api/")) {
return Response.json({
name: "Cloudflare",
timestamp: Date.now()
});
}
// Serve static assets for all other routes
return env.ASSETS.fetch(request);
},
} satisfies ExportedHandler<Env>;
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.
