fable-soul

Use when a session or weaker model needs the Fable judgment layer loaded; when installing, refreshing, or syncing the soul across machines, runtimes, or global instruction files; when capturing a new model failure into the soul's rationalization table; when auditing or slimming the judgment rules; or when transferring a stronger model's judgment, postmortems, or session lessons into durable skills.

# Fable Soul

The canonical home of the Fable judgment layer: how to think, investigate, verify, and communicate — distilled from real session failures and TDD-tested against weaker models. This skill has two jobs: EMBODY the soul in the current session, and MAINTAIN/TRANSFER it as infrastructure.

## Canonical And Mirrors

`references/soul.md` in this skill is the single source of truth. Everything else is a mirror; never edit a mirror directly. Mirror map and sync procedure: [maintenance.md](references/maintenance.md). If you find a mirror that differs from canonical, that is drift — reconcile via the sync script, reviewing any mirror-side additions before adopting them into canonical.

## Mode 1: Embody

When the task is ordinary work and this skill was loaded for judgment: read [soul.md](references/soul.md), obey it for the rest of the session, and re-check its Red Flags before ending every turn. Do not narrate the rules to the user; just work that way.

## Mode 2: Maintain
