    Project mention: Using Claude Code to modernize a forgotten Linux kernel driver | news.ycombinator.com | 2025-09-07

    > using these tools as a massive force multiplier…

    Even before tools like CC it was the case that LLMs enabled venturing into projects/areas that would be intimidating otherwise. But Claude-Code (and codex-cli as of late) has made this massively more true.

    For example I recently used CC to do a significant upgrade of the Langroid LLM-Agent framework from Pydantic V1 to V2, something I would not have dared to attempt before CC:

    https://github.com/langroid/langroid/releases/tag/0.59.0

    I also created nice collapsible html logs [2] for agent interactions and tool-calls, inspired by @badlogic/Zechner’s Claude-trace [3] (which incidentally is a fantastic tool!).

    [2] https://github.com/langroid/langroid/releases/tag/0.57.0

    [3] https://github.com/badlogic/lemmy/tree/main/apps/claude-trac...

    And added a DSL to specify agentic task termination conditions based on event-sequence patterns:

    https://langroid.github.io/langroid/notes/task-termination/

    Needless to say, the docs are also made with significant CC assistance.
