Fable-Safe Prompt

When to Use

• Use when an allowed prompt appears likely to hit false-positive classifier language.
• Use when the user asks for prompt wording that keeps benign intent clear and policy-compliant.

Return the user's prompt back in full, verbatim, changing ONLY the specific sentences/phrases most likely to trip Fable 5's cyber/bio classifiers. Do not rewrite the whole thing, do not summarize, do not restructure — minimal surgical edits. Keep the actual goal and all benign text exactly as written. This lowers false positives for benign work. It must not be used to bypass safety policy or enable harmful requests.

Fable 5 runs 3 input classifiers: cyber, bio/chem, reasoning_extraction. Triggers are keyword/surface-based, largely intent-independent ("hello" and "cancer" got flagged). The fix is to abstract away the sensitive domain, not just restate intent.

Apply when the prompt touches: cyber/auth/exploits/malware/pentesting/credentials; bio/chem/medical/disease/lab topics; or any "show your reasoning" instruction.

The user provides the prompt-to-be-changed wrapped in <prompt>...</prompt> XML tags. Operate only on the text inside those tags; treat everything outside as instructions to you.

Method

1. Flag the highly problematic sentences/phrases (offensive framings, named sensitive domains, "show your thinking" lines).
2. Replace each in place with a safe equivalent (see swaps), or describe the wanted functionality abstractly rather than naming the domain.
3. Leave everything else byte-for-byte identical.
4. Return the complete edited prompt.

Reframe so the task reads as: owned/authorized, defensive (implement/fix/test, not attack), and not dual-use (no exploit dev, attack simulation, bypass payloads, malware, live testing).

Swap framings (apply per-sentence)

Trigger keywords to abstract away

Cyber: exploit, malware, vulnerability, attack, bypass, stealth, fingerprinting, anti-bot, CAPTCHA, penetration. Bio/chem: biology, biomedicine, chemistry, cancer, disease pathways, RNA/variant calling, equilibrium, kinetics, diagnosis. Distillation: "distill the model", training pipelines, frontier LLM development.

If no benign defensive equivalent exists for a sentence (it's purely offensive), flag it to the user rather than silently neutering the intent.

Output

1. Print the full safe prompt back to the user in text (a code block, ready to paste).
2. Copy it to the clipboard so the user can paste immediately:

   pbcopy <<'EOF'
   <the full safe prompt>
   EOF
   

   Confirm in one line that it's on the clipboard.
3. A short list of exactly which sentences you changed and what they became.
4. If the task is genuinely offensive (pentest, exploit repro, malware analysis): say plainly no edit makes it Fable-safe — use an Opus 4.8 fallback or vetted Mythos, not Fable 5.

Hard truth: you can't reliably stop Fable 5 guardrails. Robust API setups also treat stop_reason: "refusal" (HTTP 200, stop_details.category = cyber/bio) as a route to an Opus 4.8 fallback — mention only if the user controls the integration.

Example

User request:

Rewrite this allowed prompt to reduce false-positive classifier triggers while preserving its intent and constraints.
