# jackin-dev (https://jackin.tailrocks.com/reference/crates/jackin-dev/)



{/* GENERATED from crates/jackin-dev/README.md — edit the README, not this file */}

The `jackin-dev` PR-verification and contributor tooling binary — installed locally and used to prepare an isolated checkout for reviewing/verifying a PR (`jackin-dev pr sync`, `jackin-dev pr path`, env setup). A developer/agent tool, not part of the jackin❯ runtime.

## What this crate owns [#what-this-crate-owns]

* The `jackin-dev` CLI (`main`): PR-sync, PR-path resolution, env-script emission, and related contributor workflows.
* Its own unit tests (`tests`).

## Architecture tier and allowed dependencies [#architecture-tier-and-allowed-dependencies]

**Standalone binary (tooling).** No workspace dependencies — it bootstraps an environment *before* the workspace is necessarily built, so it must not depend on jackin❯ runtime crates. Third-party deps are kept minimal.
