Wraps Rust cargo commands and returns structured JSON instead of terminal text. You get build, test, clippy, fmt, and doc operations as typed data, which means no more parsing ANSI codes or locale-specific output when your agent needs to check compilation errors or test results. Part of the broader Pare toolkit that does this for 28 different developer tools. Pare's benchmark shows cargo build output drops from 436 tokens to 138 in structured form, and test results go from 351 to 190. If you're building agents that work with Rust projects and you're tired of regex-ing cargo output, this gives you consistent JSON schemas across platforms and cargo versions.
