+ * Simple Self-Correcting Agent
+ *
+ * This script demonstrates a minimal self‑correcting agent that
+ * takes a string input and attempts to correct common typos such as
+ * extra spaces, missing punctuation, and simple misspellings using
+ * a small dictionary.
+ *
+ * The implementation uses only the Node.js standard library
+ * and does not depend on any external frameworks.
