    Automated TDD enforcement for Claude Code

    I have been using Claude Code with TDD through hooks, which significantly improved my workflow for production code.

    Watching the ChatGPT 5 demo yesterday, I noticed most of the code seemed oriented towards one-off scripts rather than maintainable codebases which limits its value for me.

    Does anyone know if ChatGPT 5 or Copilot have similar extensibility to enforce practices like TDD?

    For context on the approach: https://github.com/nizos/tdd-guard

    I use pre/post operation commands to enforce TDD rules.

  3. claude-code-router

    Use Claude Code as the foundation for coding infrastructure, allowing you to decide how to interact with the model while enjoying updates from Anthropic.

  4. avante.nvim

    Use your Neovim like using Cursor AI IDE!

    I've been using codecompanion.nvim[0] combined with mcp-hub.nvim[1]. Code Companion works well for interactive chat but falls short for agentic coding. It's limited to some pre-configured and user-defined "workflows" which are basically templated steps with prompts, actions, and loops.

    I've been meaning to give avante.nvim[2] a try since it aims to provide a "Cursor like" experience, but for now I've been alternating between Code Companion for simple prompts and Claude CLI (in a tmux pane next to Neovim) for agentic stuff.
