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 | $0.00034 | $0.01135 |
| Opus 5 | $0.00017 | $0.00567 |
| Sonnet 5 | $0.00007 | $0.00227 |
| Haiku 4.5 | $0.00003 | $0.00113 |
Grade A, and why
astro-7 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 — 102 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Covers initial project setup and migration from Astro 5/6, including breaking changes and Node 22.12+ requirements. Does not cover Content Layer API details (astro-content), Server Actions (astro-actions), Islands hydration directives (astro-islands), UI framework integrations (astro-integrations), or deployment adapters (astro-deployment) — those live in their own skills.
Astro 7 Expert
Production-ready web framework for content-driven sites with unified dev runtime and Islands Architecture.
Agent Workflow (MANDATORY)
Before ANY implementation, use TeamCreate to spawn 3 agents:
- fuse-ai-pilot:explore-codebase - Analyze existing routes, layouts, and config
- fuse-ai-pilot:research-expert - Verify latest Astro 7 docs via Context7/Exa
- mcp__context7__query-docs - Check breaking changes v6→v7
After implementation, run fuse-ai-pilot:sniper for validation.
Overview
When to Use
- Building new content-driven websites or blogs
- Migrating from Astro 6 to version 7
- Configuring static, server, or hybrid output modes
- Setting up middleware for auth or redirects
- Leveraging the new Rust compiler for large sites
- Implementing Content Security Policy (CSP) headers
Why Astro 7
| Feature | Benefit |
|---|---|
| Unified Dev Runtime | Dev matches production — fewer "works in dev, breaks in prod" bugs |
| Vite Environment API (Vite 8) | Exact production runtime during development |
| Single Rust Compiler | Go compiler removed — one Rust compiler for .astro files, with strict HTML parsing (unclosed tags now error instead of being silently auto-corrected) |
| Live Content Collections | Real-time data from external sources |
| Built-in Fonts API (stable) | Zero-config font loading with performance optimization |
| CSP Support (stable) | Built-in Content Security Policy nonce management |
| Cloudflare Workers | First-class support with workerd runtime in dev |
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-7 is a skill published in the GitHub repository fusengine/agents (25 stars, last pushed 29d ago), licensed MIT. It adds 34 tokens to every session and 1,135 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.
