+
+This file is written for automated coding agents (for example: Copilot coding agents). It exists to provide a concise operational contract and guardrails for agents working in this repository. It is not the canonical source for design or style rules. Those live in the developer documentation linked below.
+
+## Organization-wide guidelines (required)
+
+- Follow the prioritized shared instructions in [hoverkraft-tech/.github/AGENTS.md](https://github.com/hoverkraft-tech/.github/blob/main/AGENTS.md) before working in this repository.
+
+## Quick Start
+
+This project is a collection of **opinionated GitHub Actions** and **reusable workflows** tailored for Node.js continuous integration pipelines. For comprehensive documentation, see the main [README.md](README.md).
+
+### Key Sections to Reference

+- **[Actions](README.md#actions)** – Catalog of available actions by category
+- **[Reusable Workflows](README.md#reusable-workflows)** – Orchestration workflows for Node.js CI
+- **[Development Workflow](README.md#development-workflow)** – Commands and conventions for local development
+- **[Contributing](README.md#contributing)** – Guidelines for contributing to the project
+
+## Agent-Specific Development Patterns
+
+### Critical Workflow Knowledge
+
+```bash
+# Essential commands for development
+make lint        # Run Super Linter (dockerized)
+make lint-fix    # Auto-fix linting issues
+gh act -W .github/workflows/__test-workflow-continuous-integration.yml  # Optional: exercise reusable workflows locally
+```

-Opinionated GitHub Actions and workflows for continuous integration in Node.js context
+Opinionated GitHub Actions and reusable workflows for Node.js continuous integration pipelines.
 
 ---
 
+## Overview
+
+This repository centralizes the Hoverkraft toolkit for building, testing, and shipping Node.js projects on GitHub. It bundles:
+
+- Composite actions that detect project tooling, manage dependencies, and bootstrap runtimes.
+- Reusable workflows that apply those actions to deliver consistent CI pipelines across repositories.
+
 ## Actions
 
-### - [Get package manager](actions/get-package-manager/README.md)
+### Dependencies
+
+_Actions dedicated to caching and validating Node.js dependencies._
+
+#### - [Dependencies cache](actions/dependencies-cache/README.md)
+
+#### - [Has installed dependencies](actions/has-installed-dependencies/README.md)
+
+### Environment setup
 
-### - [Has installed dependencies](actions/has-installed-dependencies/README.md)
+_Actions focused on discovering and preparing the Node.js environment._
 
-### - [Setup node](actions/setup-node/README.md)
+#### - [Get package manager](actions/get-package-manager/README.md)
 
-## Workflows
+#### - [Setup node](actions/setup-node/README.md)
 
-### - [Continuous Integration](.github/workflows/continuous-integration.md)
+## Reusable Workflows
+
+### Continuous Integration
+
+- [Continuous Integration](.github/workflows/continuous-integration.md) — documentation for the reusable Node.js CI workflow.

+Contributions are welcome! Please review the [contributing guidelines](CONTRIBUTING.md) before opening a PR.
+
+### Action Structure Pattern
+
+All actions follow a consistent layout:
+
+```text
+actions/{category}/{action-name}/
+├── action.yml          # Action definition with inputs/outputs
+├── README.md           # Usage documentation and examples
+└── index.js / scripts  # Optional Node.js helpers (when required)
+```
+
+### Development Standards
+
+#### Action Definition Standards
+
+1. **Consistent branding**: Use `author: hoverkraft` with `color: blue` and a meaningful `icon`.
+2. **Pinned dependencies**: Reference third-party actions via exact SHAs to guarantee reproducibility.
+3. **Input validation**: Validate critical inputs early within composite steps or supporting scripts.
+4. **Idempotent steps**: Ensure actions can run multiple times without leaving residual state in the workspace.
+5. **Multi-platform support**: Test actions in both `ubuntu-latest` and `windows-latest` runners when applicable.
+6. **Cross-platform compatibility**: Uses `actions/github-script` steps for cross-platform compatibility. Avoid `run` steps.
+7. **Logging**: Use structured logs with clear prefixes (`[build-image]`, `[helm-test-chart]`, …) to simplify debugging.
+8. **Security**: Avoid shell interpolation with untrusted inputs; prefer parameterized commands or `set -euo pipefail` wrappers.
+
+#### File Conventions
+
+- **Tests**: Located in `tests/` with fixtures for container builds and chart-testing scenarios.
+- **Workflows**: Reusable definitions live in `.github/workflows/`; internal/private workflows are prefixed with `__`.
+
+#### JavaScript Development Patterns
+
+- Encapsulate reusable logic in modules under the action directory (for example, `actions/my-action/index.js`).
+- Prefer async/await with explicit error handling when interacting with the GitHub API or filesystem.
+- Centralize environment variable parsing and validation to keep composite YAML lean.
+
+### Development Workflow
+
+#### Linting & Testing
+
+```bash
+make lint                 # Run the dockerized Super Linter
+make lint-fix             # Attempt auto-fixes for lint findings
+```
