+# Python Syntax Checker Artifact
+
+## Overview
+A standalone Python script that validates Python source files for syntax errors using the AST module.
+
+## Location
+`/root/.hermes/wizard-outputs/spark/python_syntax_checker.py`
+
+## Features
+- Checks a single Python file for syntax errors
+- Can recursively check all .py files in a directory
+- Reports count of valid/invalid files and detailed error messages
+- Returns appropriate exit codes (0 = all valid, 1 = syntax errors found)
+
+## Usage
+```bash
+# Check single file
+python3 python_syntax_checker.py <file.py>
+
+# Check directory (non-recursive)
+python3 python_syntax_checker.py <directory>
+
+# Check directory (recursive)
+python3 python_syntax_checker.py <directory> --recursive
+```
+
+## Verified Tests
+1. Self-validation: Exit code 0, output "OK: ..."
+2. Bad syntax detection: Exit code 1, reports specific error
+3. Directory scanning: Found 193 valid Python files, 0 invalid
+
+## Commit
+Pushed to troupe-standup as commit 8787fb3
