Code Review

This pull request significantly improves the documentation for the search_replace tool action's operation_json parameter. The new description is well-structured with clear sections for parameters, examples, and best practices, which greatly enhances usability. I've identified a minor point of confusion in the description of one of the optional parameters and have provided a suggestion to improve its clarity.

[gemini-code-assist]

The description for exact_match_only is slightly misleading. Stating it is "Fixed as true" can be confusing, as it is a configurable parameter. This contradicts the overall action description which mentions flexible and similarity matching features. It would be clearer to state that it defaults to true and explain what happens when it's set to false.

Suggested change

	- exact_match_only (boolean): Fixed as true (default behavior)
	- exact_match_only (boolean): If `false`, enables fuzzy matching. If `true`, only exact matching is used (default: `true`).
