An expert add-on for Astro 6, a web framework for building fast sites, including sites that render partly on the server and partly in the browser. It also covers Astro content, actions, page transitions, and integration with other web frameworks.

Use it when building or maintaining Astro 6 sites, content collections, server-rendered or static pages, interactive islands, actions, view transitions, or Starlight documentation sites.

It gives an agent focused guidance when working in an Astro project and when Astro is combined with another frontend framework.

Security

Grade A, and why

fuse-astro 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 yesterday.

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.

Changes

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.
