What it does
ABCoder is an AI-oriented code-processing framework that leverages a Universal Abstract-Syntax-Tree (UniAST) to provide structural, language-independent context to LLMs. It eliminates hallucinations by allowing agents to traverse the exact AST structure of a repository rather than relying on raw text search.
Tools
- get_repo_structure: Returns the high-level architecture of the target repository.
- get_package_structure: Drills down into specific module or package layouts.
- get_file_structure: Lists files and internal organization of a directory.
- get_ast_node: Retrieves precise node details for specific code elements and their dependencies.
