A toolkit for building software in Rust, a programming language focused on speed and control over memory. It covers coding practices, code review, performance work, and asynchronous Rust, which handles tasks that wait for things like network responses.

Use it to develop Rust applications, review Rust code, optimize performance, and build asynchronous features.

It gives Rust developers guidance for reviewing code, improving speed, and working with programs that handle many waiting tasks.

Security

Grade A, and why

rust-dev 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.
