blockwatch is a cross-file drift checker written in Rust by mennanov, licensed MIT. You mark blocks in code comments, or in a blockwatch.toml for files that cannot hold comments such as JSON, and state which blocks must change together, for example a port number repeated in settings, a Dockerfile and a config. If they fall out of sync, a pre-commit hook or CI run fails. The README says it supports 37 languages and ships its own agent skill: you run blockwatch skill and an agent installs it and annotates the project. We would suggest it for repositories where docs, configs and constants are copied by hand. The limit is that someone has to write and maintain the block rules, and the Homebrew line we list installs the binary, not the skill. The repository was last pushed on 9 November 2026, as read on 11 November. We have not run it ourselves.
