Arm, check, audit or disarm the Fable Method: the PM loop, 12 checkable gates, workflow-first posture and verifier separation, persisted in Commander state. Use when the user says fable on/off/status/audit or wants verification-gated, orchestrated work.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# $ccc-fable — arm the Fable Method

**CC Commander** · $ccc-fable · a session-wide operating contract of checkable gates, so any model produces verified, orchestrated work.

The full doctrine (12 pillars, each with rule, mechanics, gate and failure prevented) lives in [rules/fable-method.md](../../rules/fable-method.md). This skill arms it, records the armed state, reports it, and audits the session against it. The user's selected model is preserved; arming changes posture, not model.

## When to use / when not to

- Use to arm the contract before substantive work (multi-file changes, audits, migrations, research), to check whether it is armed, or to self-audit a session for gate violations.
- Use `audit` before reporting a load-bearing "done" in a long session.
- Do not use it to run a build, review or plan. It governs how those run; `$ccc-orchestrate`, `$ccc-review` and `$ccc-plan` do the work.

## What happens

### 1. Route the argument

`$ARGUMENTS` selects the action. With no argument, ask with AskUserQuestion (Codex: ask the same question in plain text):

```
question: "Fable Method — what do you want to do?"
header: "Fable"
multiSelect: false
options:

How to install

The exact contents, by fingerprint

mdr add kevinzai/commander/ccc-fable@sha256:0767f90913abac86

The line at the top of this page pins the label git:20261013.fbe187d, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
