Use case overview

The author writes lots of little agents, for instance inside their music player, noting they are trivial as code.

Reported experience

  1. What they did

    The author says they write lots of small agents instead of another coding agent, one of them inside their music player. They argue a useful agent's core takes very little code, so these are trivial as code artifacts. The comment gives no mechanics beyond that.

  2. How it went

    The source states no results or numbers. It only says these little agents are easy to build, in contrast to competitive coding agents, which it calls tricky.

  3. Worth knowing

    Skip building a general coding agent, since Codex and Claude are big RL targets; small purpose-built agents are the easy part.

Example prompts

Try with Claude Code
Help me build a small agent inside [app I use, e.g. my music player or note app] that does one job: [e.g. suggest the next song based on my mood, or tag my library]. Keep it under [number] lines, use [language] and [LLM API], and explain how to run it. Finished means I can run it once on sample data and see the result.
