Developer tooling
Developer tooling here means shipping the thing other engineers touch daily: extensions, installers, mirror switchers, and small CLIs. BidiMD covers editor RTL workflows; apt-mirror-pro covers APT mirror selection; cargo-dist notes cover cross-platform Rust installers; upstream PRs (Biome and others) close false-positive loops. The pattern is the same: reduce friction in a specific environment, document the failure mode, and leave a reproducible path — not a generic “best practices” essay.
