What is better-fullstack?

A project starter and development toolkit for building full-stack applications, meaning software with both a user interface and a server. It supports several programming languages and uses an official connection to the Better Fullstack service.

Use it to create Better Fullstack projects and extend them with technologies such as TypeScript, React Native, Rust, Python, Go, Java, Elixir, or .NET.

It gives an AI assistant a defined starting structure and project-specific guidance, reducing the setup work needed before development begins.

Security

Grade A, and why

better-fullstack 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.

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.
