Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install codex-rust-practices

With no option, the skill goes to ~/.agents/skills/; add --agent claude-code (or codex, cursor…) to target an agent.

First time: connect the CLI with

npx --yes palatekit@latest login

The agent writes or reviews Rust against 63 rules drawn from the codex-rs workspace: async cancellation, error enums, process isolation, secret hardening and tests with wiremock and insta. Each rule cites the source file where the pattern lives. You get Rust code that shuts down and handles errors cleanly.
