rust-basics-practices

rust-basics-practices is a cursor rule for Cursor from wangqiqi/cursor-ai-rules. It costs 0 tokens per session (334 once invoked), scanned A, original, MIT.

Rules for organizing Rust projects and managing their dependencies with Cargo, Rust’s build and package-management tool.

In plain words
What is it for?
Use them when creating or reviewing Rust projects, Cargo configuration, dependencies, tests, examples, benchmarks, and error messages.
Why use it?
They give a consistent project structure and require attention to documentation, error handling, edge cases, and sensitive information.

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.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

rust-basics-practices 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 3d 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.

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.
