This skill should be used when the user asks for a "Fable second opinion", wants to "check a plan before committing", needs another view after repeated failures, or explicitly invokes "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 Get a focused second opinion from Claude Fable 5.1 without substituting the host tool's model. ## Route by tool 1. In Claude Code, delegate to the native `fable-advisor` agent. Do not launch another Claude Code process. 2. 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.

How to install
mdr add fcakyon/claude-codex-settings/fable-advisor@sha256:3a2520ff06a45008The line at the top of this page pins the label git:20260924.e7bd635, 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.
