+## T2R & Token Efficiency Enhancements (V2)
+- **AST Node Replacer (␍eplace_ast_node)**: Uses 	ree-sitter to deterministically edit functions and structs without relying on exact line numbers or regex matching, ensuring zero syntax breaking edits.
+- **Semantic Code Search (semantic_code_search)**: Integrates local vector embeddings to execute conceptual code searches instead of blind grep regexes, preventing hallucinated token consumption.
+- **Interactive Terminal Integrations (
+vim_send_to_terminal)**: Proxies shell execution into visible Neovim splits so human operators can watch agents compile code, debug output, and intervene interactively.
+- **Bird's Eye Architecture View (␍ead_directory_architecture)**: Generates a high-level summary of workspace directories using heuristic analysis to prevent LLMs from wasting tokens on reading dozens of files while exploring new repos.
