Its official documentation frames it as a tool for pre-commit hooks, CI checks, and incremental adoption in existing Python repositories. ### Project history The public GitHub repository was created in January 2024, and the project presents itself as a Rust-written tool for Python dependency and interface enforcement. The official docs describe `tach.toml` as the root project configuration and `tach.domain.toml` as an optional per-domain configuration file for teams that want ownership closer to module code. ### Adoption history Tach's adoption story is centered on normal developer-tool channels: pip installation, Homebrew packaging, pre-commit hooks, CI, and VS Code integration. The repository metadata and documentation emphasize incremental adoption, which matters for large Python codebases where architecture checks must coexist with existing imports before being tightened. ### How it is used Typical use starts with `tach init`, then `tach check` in local workflows or CI. Other commands visualize dependency graphs, synchronize configuration with observed imports, check external package dependencies, generate dependency maps, and run impacted tests. ### Why package nerds care Package-manager users care about Tach because it turns package/module boundaries into a checked artifact that can travel with a repository. It sits in the same practical space as linters and type checkers: installable as a CLI, cheap enough for hooks, and useful for enforcing dependency contracts before packaging or deployment. ### Timeline - 2024: Public GitHub repository created. - 2024: Official docs describe Tach as open source, pip-installable, CI-friendly, and incrementally adoptable. - 2026: Homebrew formula metadata lists `tach` as a package-manager-distributed CLI. ### Related projects - Tach relates to Python linters, import-boundary checkers, pre-commit hooks, CI dependency checks, and monorepo tooling. ### Sources - - - - - source_facts.package-manager ## Security Notes No matching local secret-handling manifest was found for tach.
