 Run test specifications. Returns a test report object. Takes [`config`](https://doc-detective.com/reference/schemas/config.html) as input. Parses paths in the `config.input` for test specifications to perform.
 
+## Debug Mode
+
+Doc Detective Core supports a debug step-through mode that allows you to run tests one step at a time, waiting for user input before proceeding to the next step. This is particularly useful for:
+
+- Debugging test failures
+- Understanding test execution flow
+- Manually verifying each step during development
+
+### Enabling Debug Mode
+
+Enable step-through debug mode by setting the `debug` configuration option:
+
+```javascript
+const { runTests } = require("doc-detective-core");
+
+const config = {
+  input: "path/to/your/tests",
+  debug: true  // or debug: "stepThrough"
+};
+
+const results = await runTests(config);
+```
+
+### Debug Features
+
+**Step-Through Mode**: When enabled, the test execution will pause before each step and display:
+- Current context and step information
+- Step description and action type
+- Interactive prompt for user input
+
+**Interactive Controls**: During debug pauses, you can:
+- Press `c` or type `continue` to proceed to the next step
+- Press `q` or type `quit` to stop test execution
+
+**Non-Interactive Support**: In non-interactive environments (CI/CD, scripts), debug mode will automatically continue without pausing, allowing tests to run normally while still logging debug information.
+
+### Example Debug Session
+
+```
+--- DEBUG STEP-THROUGH MODE ---
+⏸️  Step-through mode: Paused before next step
+Context: my-test-context
+Step ID: step-1
+Step Description: Click the login button
+Step Action: click
+
+Options:
+  [c] Continue to next step
+  [q] Quit execution
+Choice: c
+```
+
+### Future Enhancements
+
+The debug system is designed to support additional features in future releases:
+- **Breakpoints**: Pause at specific step IDs
+- **Break on Fail**: Automatically pause when a step fails
+- **Variable Inspection**: View step outputs and variables
+
+*Note: Advanced debug features require schema updates in doc-detective-common*
+

 **Step-Through Mode**: When enabled, the test execution will pause before each step and display:
 - Current context and step information
 - Step description and action type
+- Step variables that will be set (if any)
 - Interactive prompt for user input
 
+**Auto-Break on Failure**: Debug mode automatically pauses when a step fails, allowing you to inspect the failure before continuing.
+
+**Sequential Execution**: Debug mode forces `concurrentTests` to 1 for sequential execution to ensure proper step-through behavior.
+
 **Interactive Controls**: During debug pauses, you can:
 - Press `c` or type `continue` to proceed to the next step
 - Press `q` or type `quit` to stop test execution
+- Press `v` or type `view` to display available variables and their values
+- Press `e` or type `evaluate` to interactively evaluate expressions with current context
+- Press `s` or type `set` to set environment variables for testing
+
+**Variable Inspection**: View and interact with the test execution context:
+- Environment variables (with truncated display for long values)
+- Meta values and hierarchical test structure
+- Step outputs from previous actions
+- Interactive expression evaluation using Doc Detective's expression syntax
 
 **Non-Interactive Support**: In non-interactive environments (CI/CD, scripts), debug mode will automatically continue without pausing, allowing tests to run normally while still logging debug information.

-### Future Enhancements
+### Current Features
 
-The debug system is designed to support additional features in future releases:
-- **Breakpoints**: Pause at specific step IDs
-- **Break on Fail**: Automatically pause when a step fails
-- **Variable Inspection**: View step outputs and variables
+The debug system includes these implemented features:
+- **Step-Through Mode**: Pause before each step execution
+- **Auto-Break on Failure**: Automatically pause when steps fail
+- **Variable Inspection**: View environment variables, meta values, and step outputs
+- **Expression Evaluation**: Test expressions interactively with current context
+- **Environment Variable Setting**: Modify variables during debugging sessions
+- **Sequential Execution**: Forces single-threaded execution for predictable debugging
+
+### Future Enhancements
 
-*Note: Advanced debug features require schema updates in doc-detective-common*
+Additional features planned for future releases:
+- **Breakpoints**: Pause at specific step IDs or conditions
