+  summary: Native TOML 1.0 parser and writer for Mojo - Complete + Partial 1.1 🔥
+  description: |
+    mojo-toml is a native TOML 1.0 parser and writer for Mojo, enabling
+    fast and efficient parsing and writing of TOML configuration files with zero
+    Python dependencies.
+
+    Features:
+    - Complete TOML 1.0 specification support
+    - Array of tables [[section]] syntax
+    - Alternative number bases (hex 0xDEAD, octal 0o755, binary 0b1101)
+    - Partial TOML 1.1: \xHH and \e escape sequences
+    - TOML writer with full round-trip fidelity
+    - Nested table structures with proper Dict navigation
+    - Dotted keys for creating nested structures
+    - Duplicate key detection
+    - Clear error messages with line/column context
+    - 168 comprehensive tests (127 parser + 41 writer)
+    - Performance: 24μs for simple parses, 2ms for real-world files
+    - Comprehensive benchmark system
+
+    Perfect for configuration files, build systems, and any Mojo application
+    needing structured configuration.
