Notes on LLM usage

For the initial sketching stage, Crush is used for an agent-centric workflow. Then, at the refining and refactoring stage, VS Code and GitHub Copilot are used for a human-centric workflow. Throughout the process, no "YOLO" or "Always approve" features are enabled.

Commits involving agentic LLMs are highlighted with trailer Assisted-by with model name and provider. Often, the prompt to the LLM is also attached in the commit message.

Commits not marked with Assisted-by are written purely by a human.

An LLM assisted commit is as follows:

    Add responsiveness to narrow screens

    Prompt:

    ```plain-text
    Currently, this page works well on desktop, but layouts awkwardly on mobile.
    Please add responsive layout for mobile; On narrow screens, the Search Input
    Box and Search Button should maintain a 3-to-1 ratio on the same row. Please
    also adapt the link row to narrow screens.

    The Search Button now will wrap on narrow screen. Please stop it from wrapping,
    if needed it is okay to shrink out the Search Bar's space. The tooltip inside
    Search Bar should truncate and show ellipsis (...) if overflowed.
    ```

    Assisted-by: GPT-5.3-Codex (GitHub Copilot)

/AGENTS.md contains the general instructions used throughout the whole process. Each prompt will have this file attached or referenced, depending on the specific agentic tool.

The whole journey took about ~3.5 hours, including the setup of third-party providers, writing prompts and documents, scaffolding, a relaxed lunch, and various manual refactor and correction.
