23. serena

    22 17 24,975 9.9 Python

    A powerful MCP toolkit for coding, providing semantic retrieval and editing capabilities - the IDE for your agent

    

    Project mention: Ask HN: SoTA of Context Building Methods | news.ycombinator.com | 2026-04-06

    You should add Serena https://github.com/oraios/serena to your list.

    Serena gives you symbol-level navigation, reading, and editing via tree-sitter. So you're already getting much of what CoderLM offers — plus Serena has editing capabilities(replace symbol body, insert before/after symbol, rename). GitNexus goes further with the graph/impact analysis layer on top.

    I personally use Serena and GitNexus.

    The case for using both

      - GitNexus tells you what to change (impact analysis, dependency maps, blast radius)
