## Outcome Deliver one coherent Rust CLI command change that preserves the application's established grammar and boundaries, implements authorized effects safely, updates the user-visible contract, and reports focused and end-to-end verification without disturbing unrelated work. ## Compatibility Portable across Claude Code, Codex, and OpenCode. Follow the target repository's parser, sync/async dispatch, Rust toolchain, MSRV, edition, lockfile, features, targets, and CI policy; Edition 2024 examples require Rust 1.85 or newer. Network access for current primary sources is optional; when it is unavailable, report the freshness gap. Native-client compatibility remains unverified until a dated report records the client version and exact source commit. ## Use this skill when - Adding one new command, subcommand, subject, option, or command behavior to an established Rust CLI. - Changing one command's grammar, dispatch, domain request, filesystem/network effect, rendering, exit behavior, docs, and tests as one vertical slice. - Repairing a single command whose parser-to-domain integration or public process contract is broken. ## Do not use this skill when - Designing a new CLI or coordinating a multi-command architecture, output, config, or grammar redesign; use `rust-cli-application-design`. - The task is solely a reusable Rust library operation with no command-line change. - The requested change spans several independent commands or lacks a coherent existing CLI owner
