+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+This repository contains shared GitHub Actions for automating common development workflows. The primary action is `simple-commit-and-push` which safely commits and pushes changes only when they exist.
+
+## Architecture
+
+- `.github/actions/simple-commit-and-push/` - Main reusable action for committing and pushing changes
+- `.github/workflows/` - CI workflows for testing and validation
+- `Taskfile.yml` - Task runner configuration with development commands
+- `mise.toml` - Tool management configuration
+
+## Common Commands
+
+This project uses [Task](https://taskfile.dev/) as the task runner. Install tools first:
+
+```bash
+task setup
+```
+
+### Development Tasks
+
+- `task check` - Run all checks (markdown linting and GitHub Actions validation)
+- `task md:check` - Check and fix markdown files
+- `task md:lint` - Lint markdown files with markdownlint
+- `task md:lint-fix` - Auto-fix markdown linting issues
+- `task github:validate-workflow` - Validate GitHub Actions workflows with actionlint
+
+### Tool Requirements
+
+The project uses mise for tool management:
+
+- `markdownlint-cli` - For markdown linting
+- `actionlint` - For GitHub Actions workflow validation
+
+## GitHub Actions Structure
+
+### simple-commit-and-push Action
+
+Located in `.github/actions/simple-commit-and-push/action.yml`, this composite action:
+
+- Checks for changes using `git status --porcelain`
+- Only commits and pushes if changes exist
+- Configures git user settings
+- Uses token authentication for pushing
+- Supports configurable commit messages and user details
+
+**Inputs:**
+
+- `github-token` (required) - GitHub token for authentication
+- `commit-message` (optional) - Commit message, defaults to "Auto commit"
+- `user-email` (optional) - Git user email, defaults to "<action@github.com>"
+- `user-name` (optional) - Git user name, defaults to "GitHub Action"
+
+### Testing
+
+The action is thoroughly tested in `test-simple-commit-and-push.yml` workflow with three test scenarios:
+
+1. Default inputs test
+2. Custom inputs test
+3. No changes test (ensures no commit when no changes exist)
