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".
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
# 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. 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) …

How to install
mdr add richkuo/rk-skills/fable-advisor@sha256:bdb7d35e377324f3The line at the top of this page pins the label git:20261006.4c6da76, 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.
