Fable Advisor
SkillAI & modelsfable-advisor lets your AI get a second opinion from the Fable model on a plan or decision. Before committing to an approach, your AI can check its thinking with Fable and adjust course if needed. It is especially useful after repeated failed attempts, when a fresh view can break a stalemate.
Available today. Use it from your connected AI after setup.
No other account needed.

Route by tool
-
In Claude Code, delegate to the native
fable-advisoragent. Do not launch another Claude Code process. -
Elsewhere, run this exact shape from this skill's directory so the request reaches standard input:
node scripts/ask_fable.mjs <<'REVIEW' the review request REVIEW
State the decision, the evidence behind it, and any constraint that changes the verdict. Name the paths that matter: the reviewer has read-only access and checks load-bearing claims itself.
Return Fable's answer without rewriting it. If claude is missing or
unauthenticated, surface the error and ask the user to install it or sign in.
Never review in its place.
