name: fable-setup

description: Optional one-time setup for Claude Fable 5.1 in Claude Code. The plugin already injects the always-on prompting rules at every session start through a hook, so nothing needs to be edited for the defaults. Use /fable-setup to choose where the rules live (hook, a separate rules file, or a CLAUDE.md section), switch interactive/unattended mode, pick the effort default, and audit CLAUDE.md for conflicting rules. Triggers: "/fable-setup", "fable 세팅", "환경 점검", "무인 모드로", "apply the Fable guide", "set up for Fable 5.1", "unattended mode", "rules file".

# fable-setup · choose delivery, mode, effort; audit conflicts

Blocks: `${CLAUDE_PLUGIN_ROOT}/hooks/always-on.md` (+ `autonomy-unattended.md` for unattended mode).

Guide reference: `${CLAUDE_PLUGIN_ROOT}/skills/fable-prompt/references/prompt-blocks.md`.

Three layers: per request → `/fable-prompt`; always-on rules → delivered by this skill's choice (hook by

default); settings → mode, effort, and an admin checklist.

## Arguments (skip the matching question)

`auto` | `interactive` | `unattended` (mode) · `medium` | `high` (effort) · `remove` (undo everything, see Step 6).

## Step 1 · Detect (one batch of reads, silent)

`./CLAUDE.md`, `./.claude/CLAUDE.md`, `~/.claude/CLAUDE.md`, `~/.claude/settings.json`, `./.claude/settings.json`,

`~/.claude/oh-my-fable.json`, `./.claude/oh-my-fable.json`, `~/.claude/rules/`, `./.claude/rules/`,

`claude --version`, and the environment variable `CLAUDE_CODE_EFFORT_LEVEL`.

## Step 2 · Questions: one AskUserQuestion call with up to three questions

Bundle questions 1 to 3 into a single AskUserQuestion call (it supports several questions at once), each with

one-line options and the recommended one marked. No preamble, no explanation paragraphs. The goal is zero manual

steps for the user, so prefer asking over leaving something for them to do by hand.

1. **Where should the rules live?**

2. **How do you mostly work?**

- `Auto (recommended)` · detects per session: unattended for headless/SDK/agent runs, interactive in the terminal or IDE

- `Interactive` · always as if you watch and steer

- `Unattended` · always adds "the user is not watching", even in the terminal

3. **Effort default?**

- `medium (recommended)` · Fable 5 quality at lower cost; raise per task with `/effort high`

- `high` · Anthropic's guide default

- `keep current` · shown with the current value from Step 1

Ask afterwards, only when relevant, one more call:

4. **Scope?** (only when the current directory is a git repo with its own CLAUDE.md)

- `All projects (recommended)` · global files under `~/.claude`

- `This project only` · files under `./.claude`

5. **Fix the conflicting rules for you?** (only when Step 4 finds conflicts; ask after showing the table)

- `Yes, apply the suggested edits` · edits CLAUDE.md, needs approval outside auto mode

- `No, just show me` · you edit by hand

Ask in the user's language.

## Step 3 · Apply

**Config** (always, global `~/.claude/oh-my-fable.json` or project `./.claude/oh-my-fable.json`):

```json

{"enabled": true, "mode": "auto", "delivery": "hook"}

```

If the write is refused, print the JSON and path; defaults apply without a file.

**Rules text** = `always-on.md`, with `autonomy-unattended.md` inserted after the heading when unattended. English

- `claude-md`: insert or replace between `<!-- oh-my-fable:start v1 -->` and `<!-- oh-my-fable:end -->` in the

chosen CLAUDE.md with the Edit tool; touch nothing else. Set `"delivery": "claude-md"`. If refused, do not retry

with another tool: say it needs a session outside auto mode, keep `hook`, and show the section for manual paste.

**Effort**: `high` or `medium` → set `effortLevel` in `~/.claude/settings.json` (merge, keep other keys; valid

values are low, medium, high, xhigh). An approval prompt may appear; that is expected. If a

`modelSettings.<model>.effortLevel` or the env var `CLAUDE_CODE_EFFORT_LEVEL` overrides it, say which one wins

in one line. If the write is refused, show the one-line change instead.

**Copies are snapshots.** A rules file or CLAUDE.md section is the text at install time. After a plugin update,

run `/fable-setup` again to refresh it; the hook delivery always uses the current text.

## Step 4 · Audit (one table, then question 5)

Rule found → verdict → one-line suggestion. Edit CLAUDE.md only if the user chose "Yes" in question 5; if

the edit is refused, show the exact replacement text once and move on.

Conflicts to flag: narration suppression ("hold findings for the final response", "no closing recap"),

anti-formatting rules ("no bullets", "no headers"), "ask before every step". Same-meaning rules → "already covered".

## Step 5 · Verify and close

Hook: run `bash "${CLAUDE_PLUGIN_ROOT}/hooks/session-start.sh"` with `CLAUDE_PROJECT_DIR` set and confirm the

> Done. Rules: <delivery>, mode: <mode>, effort: <effort>. They apply automatically from the next Claude Code

> session. To use them in this session right now: if the plugin was installed in this session, type

> `/reload-plugins` first, then `/clear` (one per line; the rules are injected on session start, /clear, and

> compaction). Ask as usual; for short or vague requests use `/fable-prompt <request>`. Add "just the prompt"

> to preview only.

One status line: DONE, DONE_WITH_CONCERNS, or NEEDS_CONTEXT.

## Step 6 · `/fable-setup remove`

Undo everything this skill may have written, then tell the user to run `claude plugin uninstall oh-my-fable@oh-my-fable`:

- delete `~/.claude/oh-my-fable.json` and `./.claude/oh-my-fable.json`

- delete `~/.claude/rules/oh-my-fable.md` and `./.claude/rules/oh-my-fable.md`

- remove the `<!-- oh-my-fable:start` … `<!-- oh-my-fable:end -->` section (and its heading line) from any CLAUDE.md

- `effortLevel` in settings.json is left as is; say so in one line
