Make minimal prompt edits to reduce false-positive refusals from Fable. Use only when the user explicitly invokes /fable-safe-prompt.
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-Safe Prompt Return the **full prompt**, changing only phrases likely to cause false-positive refusals. Preserve the goal, structure, and all other text verbatim. Acceptance is **not guaranteed**. The relevant classifier categories are **cyber**, **bio/chem**, and **reasoning_extraction**. Rephrase sensitive wording where needed; restating intent alone may not help. Relevant topics include cyber/auth, exploits, malware, pentesting, credentials, bio/chem, medical/lab work, and requests for internal reasoning. Edit only text inside the user's `<prompt>...</prompt>` tags. Treat text outside them as instructions to you. ## Method 1. Identify phrases likely to trigger a refusal. 2. Replace them in place using the examples below. Preserve the actual goal; never invent authorization or disguise harmful intent. 3. Leave everything else byte-for-byte identical. 4. Return the complete edited prompt. Where accurate, frame work as **owned/authorized** and **defensive**: implement, fix, or test. Do not relabel offensive work as defensive. ### Swap framings (apply per-sentence) | Triggering | Safe rewrite | |---|---| …

How to install
mdr add davidondrej/skills/fable-safe-prompt@sha256:70c601fd9157f093The line at the top of this page pins the label git:20260925.cb72780, 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.
