DeltaLens FAQs

Question 1

What programming languages does DeltaLens currently support?

Accepted Answer

DeltaLens currently supports Python, JavaScript, and TypeScript. The roadmap includes plans to expand language support to Go, Rust, Java, C/C++, Ruby, and PHP in the future.

Question 2

What kind of token reduction can I expect with DeltaLens?

Accepted Answer

DeltaLens delivers significant token reduction, typically 15-40x on multi-file changes. This is achieved through a three-layer process involving change classification (interface vs. implementation), scored impact assessment, and token budget allocation (full source, signatures, or summaries).

Question 3

Does DeltaLens update context quickly on large codebases?

Accepted Answer

Yes, DeltaLens is built for speed. It provides sub-second incremental updates even on very large repositories (up to 5,000 files), ensuring your AI assistant always has up-to-date and relevant context without delays.

Question 4

What is DeltaLens and how does it optimize AI coding assistants?

Accepted Answer

DeltaLens is a tool that sits between your codebase and AI coding assistants, providing semantic-diff-aware code intelligence. It optimizes context by using Tree-sitter static analysis and change classification to send only the minimum viable and most precise code context, dramatically improving AI understanding.

Question 5

Which AI coding tools are compatible with DeltaLens?

Accepted Answer

DeltaLens is designed for native integration with Model Context Protocol (MCP) compatible AI tools. This includes popular assistants like Claude Code, Cursor, and Windsurf, allowing seamless context optimization.
