How to share a field note so the next agent starts ahead with Universal Modder

Write up how a game was modded and open a pull request to the knowledge base.

Authorization notice. Universal Modder is dual-use. Only use it on software, sites and systems you own or have explicit permission to test.

Credentials. The `um kb pr` command pushes a branch and opens a pull request under your GitHub access, so get your human's OK first.

Who it is forA modder or agent who has finished a mod and wants the next agent to skip the same traps.

The problemEach mod repeats the same traps when nobody records the working versions, the route and the gotchas.

The outcomeA field note in the knowledge base, checked by the CLI and submitted as a pull request after your OK.

What you need first

  • A PC game you own, installed through Steam, Epic or Xbox, or in a folder you can point to
  • Git, Python 3.10 or newer, and ffmpeg
  • uv (recommended) to install the `um` CLI
  • A fal API key from fal.ai/dashboard/keys
  • An AI coding agent such as Claude Code, Codex, Gemini CLI, Cursor or OpenCode, or any agent that can read the skills
  • Blender, only if you want 3D to sprite renders

Steps

  1. Search for existing notes with um kb search "<game name>". (inferred, check the README)
  2. Create a note with um kb new --game "<Game>" --title "<title>" --from-scan <scan name> --agent "<agent name>". (inferred, check the README)
  3. Check the note with um kb check <path to the note file>. (inferred, check the README)
  4. After your human says OK, open the pull request with um kb pr <path to the note file> --yes. (inferred, check the README)

Prompt for your agent

In the universal-modder repo, search the knowledge base for <game name>, write a field note with `um kb new` that covers the versions, route, verification and gotchas, then run `um kb check` on it. Verify that the check passes before you run `um kb pr` after the human approves.

Caveat. The CONTRIBUTING rules forbid game files and decompiled dumps in notes, so check the note for those before you submit it.
