fable-advisor skillA

fable-advisor is agent-read markdown (skill) from richkuo/rk-skills: Use when the user wants a task executed by the current session model with a persistent Fable 5.1 advisor overseeing it. A read-only Fable 5.1 subagent writes the plan and answers checkpoint consults; a separate fresh Fable 5.1 reviewer issues a binding pre-commit verdict. Accepts a GitHub issue or a prose task. Trigger on "/fable-advisor", "fable-advisor <task or issue>", or "execute this with a fable advisor"..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

What the file says

# fable-advisor

The main agent (the **executor**) builds. A persistent **Fable 5.1 advisor** subagent writes the plan and answers checkpoint consults. A **separate fresh Fable 5.1 reviewer** gives the binding pre-commit verdict, so the plan's author never grades its own build. Never merge the two roles. An issue task runs `work-on-issue`'s pipeline; a prose task takes a lighter path.

## Input

An issue reference (URL, `#<N>`, `<N>`, `owner/repo#N`), a prose task, or both (the issue defines the task, the prose adds constraints). With an issue, the plan and the verdict are also posted as issue comments. Ask what to execute only when none is clear. With no issue, never invent one or post anywhere.

## Model check

If the main agent already runs on Fable 5.1, say the advisor is redundant and ask whether to proceed, run the task directly, or switch to Sonnet first (`/model sonnet`).

## Steps

### 1. Resolve and gate-check the issue (only if one is referenced)
