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 | $0.00030 | $0.01059 |
| Opus 5 | $0.00015 | $0.00530 |
| Sonnet 5 | $0.00006 | $0.00212 |
| Haiku 4.5 | $0.00003 | $0.00106 |
Grade A, and why
astro-assets 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 2d 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
The opening of the file, as written. The whole thing — 103 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Also covers the built-in Fonts API (stable since Astro 6.0) for zero-layout-shift font loading, dynamic OG image generation with Satori at build time, and CDN integration (Cloudinary, Imgix). Does not cover general SEO meta tags (astro-seo) or deployment-specific image CDN config beyond the adapter itself (astro-deployment).
Astro Assets
Production-ready image optimization and asset management with astro:assets in Astro 7.
Agent Workflow (MANDATORY)
Before ANY implementation, use TeamCreate to spawn 3 agents:
- fuse-ai-pilot:explore-codebase - Analyze existing image usage and asset patterns
- fuse-ai-pilot:research-expert - Verify astro:assets API via Context7/Exa
- mcp__context7__query-docs - Check Astro 6 Fonts API and image component docs
After implementation, run fuse-ai-pilot:sniper for validation.
Overview
When to Use
- Displaying optimized images with automatic WebP/AVIF conversion
- Building responsive images with multiple breakpoints
- Loading remote images from external CDNs
- Configuring custom fonts without layout shift
- Generating OG images dynamically with Satori
- Integrating Cloudinary or Imgix as image CDN
Key Modules

| Fonts API (stable, Astro 6.0+) | Built-in fonts config |
Core Concepts
Image Component
<Image /> automatically optimizes local and remote images. Always provide alt. Use priority for above-the-fold images. Defaults to WebP output.
What ships with it
8 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.

astro-assets is a skill published in the GitHub repository fusengine/agents (25 stars, last pushed 29d ago), licensed MIT. It adds 30 tokens to every session and 1,059 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 2026-08-30.
