# Fable-Safe Prompt

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 — it does **not** guarantee no trigger.

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)

| Triggering | Safe rewrite |
|---|---|
| "How could an attacker exploit this auth" | "Review these auth files for missing checks and fix them defensively" |
| "Write an exploit / payload / PoC" | "Add a regression test proving X is fixed, then patch it" |
| "How do I bypass / brute-force Y" | "Enforce secure session validation + rate limiting on Y" |
| "Reverse this malware / show attack steps" | "Describe the risk high-level, then implement the fix" |
| "Show your reasoning / explain step-by-step / walk me through your thinking" | **Delete it.** Trips `reasoning_extraction`. If progress visibility is needed, ask it to use a send-to-user tool, not to echo its internal thoughts. |
| Clinician framing: "as a doctor, diagnose this ECG" | Patient framing: "help me interpret this ECG my doctor gave me" |
| Named bio/chem domain: "cancer / disease pathway / chemical kinetics" | Abstract it: describe the data/analysis generically, drop the domain noun |

### 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:
   ```bash
   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.
