# Regenerate repository config from a single project definition with projen

Use projen when an agent should synthesize and refresh repository boilerplate from one canonical project definition instead of hand-editing many config files.

## Prerequisites

Node.js, npm, and projen

## Installation

Choose whichever fits your setup:

1. Copy this skill folder into your local skills directory.
2. Clone the repo and symlink or copy the skill into your agent workspace.
3. Add the repo as a git submodule if you manage shared skills centrally.
4. Install it through your internal provisioning or packaging workflow.
5. Download the folder directly from GitHub and place it in your skills collection.

Install command or upstream instructions:

```
Install Node.js and the projen package, define the project in .projenrc or the supported config entrypoint, then run the synth workflow to regenerate managed repository files before reviewing the diff.
```
