The expression &self.buffer.clone() creates a reference to a temporary value. While this may compile in some cases due to temporary lifetime extension, it is an anti-pattern and can be confusing or lead to bugs. It's much clearer and safer to bind the cloned String to a variable first and then take references to it.

Additionally, cloning the entire buffer on each call to parse_incremental can be inefficient, especially for large inputs. If possible, consider a refactor that would allow you to modify the buffer in-place (e.g., using drain()) to improve performance.

Passing &mut false to helpers::reset_current_tool_state will cause a compilation error, as it's not possible to create a mutable reference to a literal false.

To fix this, you should declare a local mutable variable and pass a reference to it instead. This issue also suggests a potential design flaw, as the helper function seems to have different requirements than what this parser provides (i.e., this parser doesn't use current_tool_name_sent).

This Glm47MoeParser is almost an exact copy of Glm4MoeParser, with the only significant difference being the func_detail_extractor regex. This approach introduces a large amount of duplicated code, which will make maintenance more difficult and error-prone.

I strongly recommend refactoring to avoid this duplication. A better approach would be to create a single, generic GlmParser struct that can be initialized with the specific regex pattern required for a given GLM version. This would centralize the parsing logic and make it easier to support future versions.

For example, you could have a generic parser and instantiate it in factory.rs like so:

// In factory.rs
registry.register_parser("glm4_moe", || Box::new(GlmParser::new(r"(?s)<tool_call>([^
]*)
(.*)</tool_call>")));
registry.register_parser("glm47_moe", || Box::new(GlmParser::new(r"(?s)<tool_call>\s*([^<\s]+)\s*(.*?)</tool_call>")));

This would eliminate nearly 300 lines of duplicated code.

The Mermaid diagrams on lines 59 and 69 are inconsistent with the implementation, as they depict GLM47 as a separate parser. Since glm47 uses the glm45 parser, it would be clearer to either remove the GLM47 entries from the diagrams or show it as an alias for GLM45 to avoid confusion.

This documentation is inconsistent with the implementation in reasoning_parser/factory.rs, which maps the glm47 model pattern to the existing glm45 parser. A new glm47 parser is not actually introduced. To avoid confusion, I recommend merging the glm47 information into the glm45 description.

This mapping should point to glm45, as the factory maps the glm47 pattern to the glm45 parser.

This new function is now a generic constructor that takes a regex pattern. To create a safer and cleaner public API, consider making this function private to the crate (pub(crate) fn new(...)) and only exposing the specific glm4() and glm47() factory methods. This would prevent users from providing invalid regex patterns that could cause a panic at runtime due to the .expect() call.

This type alias can be confusing. It suggests that Glm47MoeParser is a distinct type, but it's just an alias for Glm4MoeParser. This allows for confusing calls like Glm47MoeParser::glm4().

To improve clarity, I'd recommend removing this alias and using Glm4MoeParser directly in all places, including the new test file tests/tool_parser_glm47_moe.rs. The parser's behavior is determined by the factory method used (glm4() vs. glm47()), and relying on that is clearer than using a type alias.
