How to install

This mod is not in the official Claude directory, so you load it straight from its source on GitHub. modsforClaude.com is an unofficial community site: we do not host, repackage or install anything. Read the source and the review on this page first.

In the terminal

Clone the repository and start Claude Code with the mod. It stays loaded for that session.

git clone https://github.com/Junhan2/oh-my-fable
claude --plugin-dir ./oh-my-fable

In the desktop app

Clone the repository into a folder you keep:

git clone https://github.com/Junhan2/oh-my-fable ~/claude-mods/oh-my-fable

Add that folder to CLAUDE_CODE_PLUGIN_DIRS in the env block of ~/.claude/settings.json, then start a new session in the Code tab. On Windows, with your own user name:

"env": {
  "CLAUDE_CODE_PLUGIN_DIRS": "C:\\Users\\you\\claude-mods\\oh-my-fable"
}

On macOS and Linux:

"env": {
  "CLAUDE_CODE_PLUGIN_DIRS": "~/claude-mods/oh-my-fable"
}

Already loading other mods this way? Add the folder to the same value, separated by ; on Windows or : on macOS and Linux.

Not working, or want to change its settings? How to load a Claude Code mod walks through every step.

Anthropic's prompting-guide rules for Claude Code, always on (Opus 5.5, Fable 5.1; Sonnet 5.5, Haiku 5.5, Opus 5 and Sonnet 5 too): install and forget: the working rules load at every session start and reach subagents, unattended sessions are detected automatically and get the early-stop rules, sessions at xhigh or max effort get the stop-after-checks rule, /fable turns a rough request into a guide-aligned prompt, /fable-status shows what is in effect, /fable-audit finds which guide sections your own rules are missing, /fable-setup moves the rules into a rules file (recommended once).
