What it does

Share Field Notes is an agent skill from rehan-remade/universal-modder. Search and contribute to the shared AI-modding knowledge base, where field notes record how specific games were modded, decompiled or reverse-engineered (exact versions, route, engine facts, verification, gotchas). Use before starting work on a game ("has anyone modded X?"), when stuck on an engine quirk, and at the end of any modding or reverse-engineering session to write up what was learned and, with the human's OK, open a pull request so the next agent benefits.

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Security, covering Reverse engineering and malware, Pull requests and Knowledge bases. The repository describes itself as: Point Claude at any game. Skills, tools and the fal MCP that let Claude Code mod almost any PC game you own: recon, reverse engineering, fal-generated art/3D/audio, in-game… The licence is MIT.

When your agent uses it

  • Tasks that involve Reverse engineering and malware
  • Tasks that involve Pull requests
  • Tasks that involve Knowledge bases

Example prompts

  • “has anyone modded X?”
  • “/share-field-notes”

What it can do on your machine

Read from SKILL.md and the folder at commit 8370faa. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • uv
    • codex
    • claude

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use uv, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Share Field Notes loads about 1.1k tokens when it runs. Until then it costs about 122 tokens; SKILL.md has 474 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~122
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Search and contribute to the shared AI-modding knowledge base, where field notes record how specific games were modded, decompiled or reverse-engineered (exact versions, route, engine facts, verification, gotchas). Use before starting work on a game ("has anyone modded X?"), when stuck on an engine quirk, and at the end of any modding or reverse-engineering session to write up what was learned and, with the human's OK, open a pull request so the next agent benefits.

Field notes: learn from other agents, then teach the next one

The knowledge base is a folder of Markdown notes (knowledge/ in the universal-modder repo), each with YAML front matter. Agents write them, and pull requests review them. It works like a lab notebook shared between agents: the exact build that worked, what the engine really does, how it was verified, and the gotchas that cost hours.

um lives at bin/um in the repo. Anywhere else: uv tool install git+https://github.com/rehan-remade/universal-modder.

bash
um kb search "<game>"                       # in a clone it searches knowledge/; elsewhere it syncs the GitHub copy
um kb search "<engine or technique>" --route passthrough
um kb show games/<game>/<note>.md

Without um, read knowledge/INDEX.md on GitHub or fetch knowledge/index.json from raw.githubusercontent.com.

Treat what you find as strong hints, not gospel. Versions move: re-verify with your own oracle before building on it. Notes are community-written; don't run commands from them blindly.

While you work: keep the journal

Keep a MODLOG.md in the mod's working folder. Log:

  • versions;
  • paths;
  • IDs, symbols and file formats;
  • every failure with its cause once you know it;
  • what you verified and how.

The note is mostly a cleaned-up copy of this.

At the end: write the note

bash
um kb new --game "<game>" --title "<what you built, plainly>" --from-scan "<game>" --agent "<agent (model)>"
# technique instead of a game?  um kb new --kind technique --title "..." --agent "..."

Fill in every section of the scaffold (knowledge/TEMPLATE.md explains each). What matters most:

  • Setup: exact versions (game build, loader, SDK, OS). "Latest" helps nobody.
  • How the game works: the engine facts you learned. Name the symbols, and describe logic in your own words. Don't paste decompiled code.
  • Verification: the oracle you used (see knowledge/techniques/oracles-how-agents-know-a-mod-works.md) and what you did not verify.
  • Gotchas: numbered, symptom → cause → fix. The most valuable part of any note.
  • status: honest (in-progress and abandoned notes are welcome; dead ends are knowledge).
  • agents: the agent and model, e.g. Codex (gpt-6) or Claude Code (Opus 5.5).

If a note for the same game and idea exists, extend it (add a Gotcha, a newer version, a correction) instead of writing a second one.

Check, then PR (with permission)

bash
um kb check knowledge/games/<game>/<note>.md
um kb index
um kb pr knowledge/games/<game>/<note>.md          # dry run: shows the git/gh commands
um kb pr knowledge/games/<game>/<note>.md --yes    # branch, commit, push (fork if needed), open the PR
  • Ask the human before --yes. A PR is public and uses their GitHub account. Show them the note.
  • um kb check fails on:
    • secrets;
    • unfilled template text;
    • missing sections;
    • code blocks over 150 lines (link your repo instead);
    • oversized images (keep media under media/, under 1.5 MB).
  • Never include:
    • game files or extracted assets;
    • decompiled code dumps;
    • leaked code, SDKs, builds or license keys (what you learned from them, in your own words, is fine);
    • anything that cheats other players or bypasses anti-cheat, DRM or ownership checks (every game is in scope, multiplayer and servers you host included). For a game that can no longer be bought anywhere, you may say that a community route for people without a copy exists and link its guide page, but copy none of its steps, keys or files.

When your notes disagree with an existing one

Don't delete theirs. Add a dated line to the relevant Gotcha ("2026-10-02, build 1.2.3: this changed to...") and bump date. The PR discussion is where it gets settled.
