Take this project off 0G

Metadata

• Category: private-computer
• SDK: Not applicable. This skill configures Claude Code to reach the 0G router; it uses no 0G SDK, no wallet and no .env.
• Activation Triggers: "不用 0G 了", "退回原生", "退回原来的 API", "卸载 0G", "关掉 0G", "撤销 0G 配置"
• Supported Host: Claude Code only. It configures a project's .claude/ directory, which Cursor and GitHub Copilot do not read.
• Source: skills/0g-pc-uninstall/SKILL.md in the 0gfoundation/0g-pc-skills repository, where it is tested and released. Changes are made there first.

One job: return <project>/.claude/ to the state it was in before 0G arrived.

If the user wants a different 0G model rather than no 0G at all, that is /0g-pc-switch-model (skills/private-computer/0g-pc-switch-model/SKILL.md here) — say so and stop. People reach for "undo" when they mean "change", and uninstalling to reinstall loses their key for no reason.

Hard rules

1. Only this project's .claude/. Never delete or rewrite ~/.claude/settings.json. The user's global file holds their hooks, plugins, status line and /model choice, and it has nothing to do with 0G.
2. Removing the key is irreversible, so confirm before you start. The key lives in <project>/.claude/settings.local.json. Once it is out, it is out — 0G keys are shown at creation and not retrievable afterwards, so getting it back means issuing a new one at pc.0g.ai. Show what is about to change, wait for an answer, and only then run anything.
3. Let the installer do the removing. Run install.sh --uninstall; do not compose your own rm. The removal has moving parts that live in that script — deciding whether this project is bound to 0G at all, taking a named set of fields out of settings.local.json without disturbing anything else in it, refusing the old layout instead of guessing at it, and leaving the ignore rule in place. A hand-written rm skips all four and silently does more damage than the install ever did.
4. Nothing takes effect until the next launch. Finish by telling the user to restart.
5. Every place the user has to decide is a tool call, not a sentence. This file is loaded into whatever model drives the session, which in a project on 0G is a 0G model rather than Claude. "Ask the user first" written as prose reads as narration and gets walked past — which here means deleting a key nobody agreed to delete. Use AskUserQuestion and let it block. That tool is Claude Code's; in a host without an equivalent blocking prompt, stop and hand the choice back to the user rather than deciding for them.

1 — Say exactly what will happen

The removal is not "delete two files". What it does depends on what the install found when it arrived, so read the project and report rather than guess:

Run this from the host project root — the directory you want on 0G. These paths resolve against the working directory, so running it inside .0g-skills/ or any other checkout of this repository would configure the wrong project.

If it prints nothing to undo, say so and stop. There is nothing here to remove and no confirmation to ask for.

2 — Get a real answer

Put that output to the user with AskUserQuestion. Not a summary of it — the lines themselves, so they can see whether their own settings survive and that the key does not.

Run nothing until the answer comes back. If they decline, stop there and change nothing.

3 — Hand it to the installer

curl -fsSL https://raw.githubusercontent.com/0gfoundation/0g-pc-skills/main/install.sh | bash -s claude --uninstall

This one you may run yourself: it carries no key and takes no key. It prints what it did.

If curl cannot reach GitHub, stop and say so rather than improvising the removal by hand — hard rule 3 is about exactly this moment.

4 — Hand off

Tell the user to restart Claude Code. The running session keeps the 0G configuration until it exits.

There is nothing to unset. This used to be the step everyone missed, back when the key lived in the shell: it survived the deletion of the config, and Claude Code kept sending it to api.anthropic.com, where it is not valid — an authentication failure that reads like a broken account. The key travels with the file now. If the user still sees

⚠ another auth source is set and takes precedence over your claude.ai login

then something really is exporting ANTHROPIC_AUTH_TOKEN — an old .zshrc line, most likely, left over from the way this used to be set up.
