-# Gemini Code Assistant Guide: `screeps-deploy-action`
+# Gemini Actions
 
-This document provides a guide for Large Language Models (LLMs) and developers on understanding and interacting with the `screeps-deploy-action` project.
+This repository is maintained by Gemini.
 
-## Project Overview
+## Development Guidelines
 
-`screeps-deploy-action` is a GitHub Action designed to automate the deployment of JavaScript code to the online programming game Screeps. This project is aimed at supporting both GitHub and Gitea workflows, allowing developers to push their code from a Git repository directly to either the official `screeps.com` server or a private server. It utilizes **Gitea Workflows** (located in `.gitea/workflows`), which are largely compatible with GitHub Actions with minor syntax changes, for its continuous integration and deployment needs.
+*   **Test-Driven Development (TDD):** Wherever possible, Test-Driven Development principles should be followed. Write tests before writing the code they are intended to validate.
+*   **Pre-commit Hooks:** Ensure that `pre-commit` hooks are installed and active before making any commits. This can be done by running `pre-commit install` in your local repository.
 
-The action's core logic is in `index.js`. It uses the `screeps-api` library to communicate with the Screeps server. The action is configured via a workflow file (e.g., `.github/workflows/main.yml`) using inputs defined in `action.yaml`.
+## Repository Comparison
 
-### Key Files
+*   On request, this repository should be compared against the rules and guidelines specified in the `README.md` of the reference repository: `https://git.horstenkamp.eu/Philipp/template-git`.
 
--   **`action.yaml`**: The manifest file for the GitHub Action. It defines the inputs, outputs, and execution environment for the action.
+## Testing
--   **`index.js`**: The main entry point for the action. It contains the core logic for reading files, connecting to the Screeps API, and uploading the code.
--   **`package.json`**: Defines the project's metadata and dependencies. The key dependency is `screeps-api`.
--   **`README.md`**: Provides user-facing documentation, including setup and usage examples.
 
-## Core Functionality
+This project uses [Vitest](https://vitest.dev/) for testing. The tests are located in the `__tests__` directory.
 
-The action performs the following steps:
+To run the tests locally, use the following command:
 
-1.  **Reads Inputs**: It reads the configuration provided by the user in their workflow file. This includes server connection details, authentication credentials, and file paths.
+```bash
-2.  **Authentication**: It authenticates with the Screeps server using either a token or a username/password.
+npm test
-3.  **File Processing**:
-    *   It reads all `.js` files from the repository matching the provided `pattern`.
-    *   It can optionally perform placeholder replacements (e.g., `{{gitHash}}`, `{{deployTime}}`) in a specified file (`replace_file`) before deployment.
-4.  **Code Deployment**: It uploads the processed files to the specified `branch` on the Screeps server.
-
-## Usage
-
-To use this action, a developer would create a `.yml` file in their `.github/workflows` directory.
-
-**Example Workflow:**
-
-```yaml
-name: Deploy to Screeps
-on:
-  push:
-    branches:
-      - main
-jobs:
-  deploy:
-    runs-on: ubuntu-latest
-    steps:
-      - uses: actions/checkout@v3
-      - name: Deploy to screeps.com
-        uses: ./
-        with:
-          token: ${{ secrets.SCREEPS_TOKEN }}
-          branch: 'default'
-          pattern: '*.js'
 ```
 
-### Configuration Inputs
+### Testing Pipeline
 
-The action is configured using the `with` key in the workflow step. The available inputs are defined in `action.yaml`:
+The tests are automatically run on every push and workflow dispatch using a Gitea workflow. The workflow is defined in `.gitea/workflows/test.yaml`. All testing for this repository is done via Gitea workflows, not GitHub workflows.
 
--   **`token`**: (Required) The authentication token for the Screeps API. It is recommended to store this as a secret.
+The Gitea workflow does the following:
--   **`protocol`**: The server protocol (`http` or `https`). Defaults to `https`.
--   **`hostname`**: The server hostname. Defaults to `screeps.com`.
--   **`port`**: The server port. Defaults to `443`.
--   **`path`**: The server path. Defaults to `/`.
--   **`username`**: The Screeps username (used if `token` is not provided).
--   **`password`**: The Screeps password (used if `token` is not provided).
--   **`branch`**: The in-game branch to deploy the code to. Defaults to `default`.
--   **`pattern`**: A glob pattern for the files to deploy. Defaults to `*.js`.
--   **`replace_file`**: Path to a file where placeholders like `{{gitHash}}` and `{{deployTime}}` should be replaced.
--   **`source_map_path`**: Path to a `main.js.map` file for Source Map support.
 
-## Modifying the Code
+1.  Checks out the code.
-
+2.  Sets up Node.js.
-When asked to modify the action's behavior, the primary file to edit will almost always be `index.js`.
+3.  Installs the dependencies using `npm install`.
-
+4.  Runs the tests using `npm test`.
--   For changes to the action's inputs or outputs, `action.yaml` must also be updated.
--   The core deployment logic is within the `postCode` function in `index.js`.
--   File reading is handled by `readFilesIntoDict`.
--   Placeholder replacement is handled by `readReplaceAndWriteFiles`.
-
-Before making changes, always review the existing code and the `screeps-api` documentation to understand how it interacts with the Screeps server. After making changes, ensure that any associated tests are updated or added.
