Key Innovations in Babs

AST-Guided Context Slicing (@ast-grep/napi): Eliminates context window noise by using tree-sitter AST queries to extract precise function/class subtrees.
Reciprocal Rank Fusion (RRF) Hybrid Retrieval: Combines Lexical (fastGrep), Vector (LanceDB), and AST Code Property Graphs (CogneeGraphMemoryIndex).
Autonomous Self-Correction Loop: Captures tsc:check compiler and eslint diagnostic tracebacks, feeding errors back into LLM multi-turn edits.

Agent mode to autonomously plan, execute, and verify code tasks together with AI.

Interactive side-panel chat to query codebase context and inspect symbols.

In-editor code modification using Myers diffing and vertical diff blocks.

Inline code suggestions as you type.
