# Make Mods Your Own: Read, Tweak, and Write Mod Content with an Agent

Once your mods run, the fun part starts: finding out what is actually in them, changing what you do not like, and writing your own content. An AI agent can read every file in a mod, find the exact setting or command you need, and write new text, lore, and characters in the format the game expects. This guide teaches the method for any moddable PC game. You do not need Zo. Do [Set Up Your Gaming PC for Modding with an AI Agent](https://www.classified.llc/guides/modding-setup-with-ai-agents.md) first, so you have backups and a workshop folder.

## Hand this guide to your AI

1. Click **Copy for your agent** at the top of this page (or download the .md) and paste it into your agent.
2. If you plan to write your own content (Part 3), download [modding-content-interview.md](https://www.classified.llc/guides/kits/modding-content-interview.md) and save it in your workshop's `records` folder.
3. Send this prompt:

```
I want to understand and customize the mods I have installed for [game]. Start by reading the mod's own files and tell me what it actually contains: its systems, characters, quests or story, and the settings I can change. Don't change anything yet. Tell me which files each answer comes from.
```

> **Note for AI agents:** Base answers on the user's installed files first and cite file paths, then check the mod's official pages for anything newer. Copy any file to the backups folder before editing it, change one thing at a time, and log each change. Respect mod permissions: personal edits are fine, but redistributing someone else's files is not unless their permissions allow it.

## Part 1: Find out what is really in a mod

Mod pages go out of date, and forums are full of guesses. The mod's own files are the truth. Your agent can read them and answer questions like:

- Is there a main story or quest line, and what starts it?
- Which famous characters are actually in it, and in what role?
- What happens over time, such as scripted wars or events, and on which day?
- Which features ship turned off, and where is the switch?

A real example: a player asked whether a Lord of the Rings total-conversion mod had a story involving Frodo and Gandalf. The agent read the mod's data files. There was no main quest at all, Frodo did not appear anywhere, and Gandalf showed up only in other characters' biographies. The real structure was a scripted war that starts on a set day, war goals for each army that follow the books, and a victory meter that shipped turned off, with a setting to turn it on. That answer changed how the player approached the game, and it took the agent a few minutes.

Ask your agent to compare what it finds with the mod's official page and announcements. Sometimes that turns up something useful, like a newer version you did not know about.

## Part 2: Change things safely

### Settings first

Many mods have an in-game settings menu. Try that first, because it is the mod author's own supported way to change things. Ask your agent which setting does what. It can find the settings file and read every option and its default.

### Console commands

Many games have a developer console for cheats and testing: adding gold, raising skills, changing a character. Commands change between game versions, and old forum posts are often wrong. Ask your agent to find the exact command names and formats in your installed game files, and whether the console needs turning on first. It can also tell you which commands are harmless and which can break a save.

### Editing files

When you edit a file directly:

1. Copy the original into your backups folder first.
2. Change one thing at a time.
3. Test it in the game.
4. Write what you changed, and why, in your notes.

Two things trip people up. Some mods only reload a file when its date changes, so a copied file carrying an old date can be silently ignored. If an edit does not show up, ask your agent whether the mod caches files. And mod updates usually overwrite your edits, so keep a list of every change so you can re-apply it after an update.

## Part 3: Write your own content

This is where an agent shines. Many games load text from files: item descriptions, character biographies, dialogue, world lore. Mods that let characters talk through an AI model often read world and character files that shape what every character knows and how they speak. Your agent can write that content in the right format, in the right voice, grounded in real research.

The loop that works:

1. **Interview.** Have the agent ask you questions before it writes anything: who your character is, what kind of world you want, how harsh or forgiving, how true to history or the books. The [content interview file](https://www.classified.llc/guides/kits/modding-content-interview.md) gives it a good set of questions.
2. **Research.** For a historical or book-based setting, ask it to research the period or the source and save its notes. Ask it to keep facts and invention clearly separate.
3. **Read the format.** Ask it to study the files the mod already ships and the mod's own documentation, so new files match exactly.
4. **Draft.** It writes the files. For a big set, it can draft several parts at once from one shared brief so they stay consistent.
5. **Check.** Ask it to confirm every file loads (for example, that JSON files are valid) and that nothing contradicts the game's own world.
6. **Install and test.** Back up the mod's current files, install the new ones, play for a while, then ask the agent to read the logs and confirm the game actually used them.

A tip for character backstories: write private goals as things other characters only learn if your character tells them. Otherwise every stranger in the game already knows your secret plan.

One more: longer world files are not always better. For AI-driven characters, every extra page is more for the model to read before it answers, so very long files can make characters slow to respond. If replies drag, ask your agent what it would trim and what you would lose.

## Part 4: Share what you make

If you make something worth sharing:

- Take out your personal details: real names, file paths with your username, anything about you that is not part of the mod.
- Make a version that does not assume your exact character, so other people can use it.
- Credit the original mod and follow its permissions. Most mod sites let authors say what you may do with their files. Share your own files, and link to theirs rather than re-uploading them.

Your agent can do the clean-up pass and write the readme.
