Crespo – Tree-sitter AST blueprints instead of raw code for LLMs

Crespo replaces raw source code with Tree-sitter AST blueprints to provide LLMs with structured, syntax-aware representations of code. It is designed for developers and AI engineers building code-generation or analysis tools, who need to improve LLM accuracy and reduce token costs. This approach is interesting because it shifts the paradigm from feeding models raw text to leveraging precise structural data, enabling more reliable code understanding and generation.
