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 | $0.00041 | $0.00370 |
| Opus 5 | $0.00020 | $0.00185 |
| Sonnet 5 | $0.00008 | $0.00074 |
| Haiku 4.5 | $0.00004 | $0.00037 |
Grade A, and why
astro-ssr 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 9d 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
Astro Expert
Astro 4+ — the web framework for content-driven websites. Islands architecture for optimal performance.
Core Concepts
| Concept | Description |
|---|---|
| Islands Architecture | Interactive components as isolated "islands" in static HTML |
| Zero JS by Default | Ship no JavaScript unless explicitly needed |
| Content Collections | Type-safe content management with schemas |
| View Transitions | Built-in page transitions (MPA) |
| Hybrid Rendering | Mix SSG + SSR + prerendering per route |
Framework Integration
Astro supports multiple UI frameworks in the same project:
---
import ReactComponent from './React.tsx'
import VueComponent from './Vue.vue'
import SvelteComponent from './Svelte.svelte'
---
<ReactComponent client:load />
<VueComponent client:visible />
<SvelteComponent client:idle />
Client Directives
| Directive | When JS Loads |
|---|---|
client:load |
Immediately |
client:idle |
When browser is idle |
client:visible |
When component enters viewport |
client:media |
When media query matches |
client:only |
Skip SSR, client-side only |
Anti-Patterns
| ❌ Don't | ✅ Do |
|---|---|
| Make everything interactive | Use islands only where needed |
| Use SSR for static content | Use prerendering for static pages |
| Skip content collections | Use typed collections for content |
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.

astro-ssr is a skill published in the GitHub repository hoangatg/ai-agent-toolkit (1 stars, last pushed 5mo ago), licensed MIT. It adds 41 tokens to every session and 370 once invoked, about $0.0002 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.
