Cargo Watch

Rapid feedback with just watch

Run just watch in the background at the start of any code-editing task. It launches cargo watch -x 'clippy --workspace --all-targets' which automatically re-runs clippy on every .rs file change.

Use Bash with run_in_background: true to start it, then periodically check TaskOutput for compilation errors and clippy warnings as you edit. This catches mistakes early without waiting for a manual clippy run at the end.

Devshell provides all tools

cargo-watch, rustfmt, clippy, and the full Rust toolchain come from the Nix devshell. No manual installs needed. The justfile auto-detects whether you're inside nix develop and wraps commands accordingly.

Workspace-wide checks

Always use --workspace --all-targets flags with clippy/check to cover all crates and all target types (lib, bin, tests, examples).
