Overview

# Fable God Mode

Two installable Claude Code skills that spend your premium model where it earns its keep and push the verbose middle of every task onto cheaper models. God Mode runs on a Claude subscription alone. Super God Mode adds an independent, second-lineage Codex reviewer (default model gpt-5.6-sol) through a paid ChatGPT plan you may already have. Installation is agent-driven: you clone the repo and tell Claude to set it up, and nothing on your machine is touched without an explicit OK.

## Two modes

| | Fable God Mode | Fable Super God Mode | |---|---|---| | **Needs** | A Claude subscription | God Mode + a paid ChatGPT plan (Plus and up) + Codex CLI | | **Core idea** | The 10-80-10 loop: Fable 5 plans (10%) and reviews (10%); cheaper Claude subagents (Opus/Sonnet/Haiku) do the verbose middle 80% | Everything in God Mode, plus a Codex reviewer (default gpt-5.6-sol, fallback gpt-5.5) as a deterministic specialist and independent reviewer | | **Reviews** | Fable 5 reviews its own delegated work | Adds the Codex reviewer: backend/algorithmic critique, plan critique, diff review, debugging second opinion | | **Stale-config audit** | Yes — report-only by default, reversible archival | Same | | **Sends code off your machine** | No | Only with explicit consent (see Data disclosure) |

Both modes converge on the same operating discipline; Super God Mode is a strict superset.

## What's new in v0.3.0

- **`session-handoff`** (new, standalone): end a heavy session at a natural pause and restart clean — audited handoff doc + one paste-able resume one-liner. See `skills/session-handoff/SKILL.md`. Works without Codex (the audit falls back to a local clean-context subagent and says so; the cross-model audit runs only with established data-egress consent). Install: `/plugin install session-handoff@fable-god-mode` — or copy the folder to `~/.claude/skills/session-handoff/`. The agent-driven INSTALLER covers the two orchestration skills only; session-handoff
