cargo-path is a command-line utility that prints the path to a local Rust dependency. It is invoked as cargo path <DEPENDENCY> . For example: $ cargo path clap /Users/home/.cargo/registry/src/index.crates.io-1949cf8c6b5b557f/clap-4.6.1 When combined with the appropriate exhortation it is extremely helpful for Rust development with coding agents. With cargo-path , agents will immediately consult local sources for dependencies, which are guaranteed to be up-to-date for the correct version. Without cargo-path , agents tend to search the web for dependency documentation, which is slow and often turns up out-of-date information. AGENTS.md Snippet Always consult the local source code for information about Rust dependencies, which is guaranteed to be up-to-date for the correct version. Run cargo path NAME to find the source directory for a dependency: $ cargo path clap /Users/home/.cargo/registry/src/index.crates.io-1949cf8c6b5b557f/clap-4.6.1
