+The debug output will show the parsed AST nodes and you can compare them with the [Playground](/playground.html). You can also use different debug formats like `cst` or `pattern`.
 
 If you find there are different results, it is usually caused by incomplete code snippet in the pattern. To fix the issue, you can provide a complete context code via the [pattern object](/reference/rule.html#atomic-rules).

-:::tip What is tree-sitter error recovery?
+:::details Text encoding impacts tree-sitter error recovery.
 Tree-sitter is a robust parser that can recover from syntax errors and continue parsing the rest of the code.
 The exact strategy for error recovery is implementation-defined and uses a heuristic to determine the best recovery strategy.
 See [tree-sitter issue](https://github.com/tree-sitter/tree-sitter/issues/224) for more details.
 
 Text-encoding will affect the error recovery because it changed the cost of different recovery strategies.
