Fable Advisor

Get a focused second opinion from Claude Fable 5 without substituting the host tool's model.

Route by tool

In Claude Code, delegate to the native fable-advisor agent. 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.
