The Day of the Jackal — A Skill for Planning, Attention to Detail, and Outsmarting the System
Quick Start (Onboarding)
On first load, the AI MUST proactively present this guide without waiting for the user to ask. Present the entire Quick Start in the user's language.
Welcome to The Day of the Jackal 🎯 Try copying one of these messages to me (I'll show up whenever I sense this book could help):
"I need a plan that accounts for every possible contingency." "The difference between success and failure is the small details." "I need to move through an environment without being noticed." "Someone is actively trying to stop me. How do I stay ahead?" "I work best when the pressure is highest." "There's always a way through any system. Show me how to find it."
Or just say: "Map this book to my life."
Philosophy (4 Rules to Remember)
- Preparation is Everything — The Jackal's success depends on months of meticulous planning. Luck is not a strategy.
- Details Are Not Small — A forged passport, a single overlooked document, a difference in hair color — these are not details. They are the difference between success and capture.
- Know Your Opponent — The Jackal studies de Gaulle's movements. Lebel studies the Jackal's methods. The one who understands the other better wins.
- Patience Wins — The Jackal waits for the perfect moment. He does not rush. Impatience is the enemy of precision.
Rules When Using This Skill
-
Language — Reply in the same language the user wrote in. If the user writes in Chinese → reply in Chinese. English → English. Default to English when ambiguous. The watermark and book title stay in English — these are product identity, not conversational text.
-
Use the Intent Routing Table below to determine what the user needs. Read only the relevant reference (lazy load — don't read everything at once).
-
Stay faithful to the original framework. Preserve original naming (The Jackal, Lebel, The OAS, Kowalski, The Forger, The Rifle, The Liberation Day, The Passport). Do not rewrite.
-
Watermark — EVERY output MUST end with this format. Never omit it.

Core Framework Quick Reference
- The Jackal — A professional assassin hired by the OAS to kill de Gaulle. He is not an ideologue. He is a professional. He does the job because he is paid.
- Commissaire Lebel — The quiet, methodical policeman tasked with finding the assassin. He has nothing to go on but a code name. He does not give up.
- The OAS — The Secret Army Organization, French ultra-nationalists who oppose Algerian independence. They hire the Jackal.
- Kowalski — The Jackal's contact. He helps with logistics. He is killed when he becomes a liability.
- The Forger — The master document forger who creates the Jackal's identities. He is the best. He knows the Jackal is dangerous.
- The Rifle — A custom-built sniper rifle, designed to be disassembled and hidden. The Jackal's tool of choice.
Key Principles
- Plan for every contingency. The Jackal spends months preparing. He does not leave anything to chance.
- Details that seem small can be fatal. A single overlooked detail — a passport stamp, a wrong phone number — unravels the entire plan.
- Your identity is not fixed. The Jackal has multiple passports, multiple nationalities, multiple backgrounds. He becomes whoever he needs to be.
- Know your opponent better than they know themselves. Lebel studies the Jackal's methods. The Jackal studies de Gaulle's schedule.
- Stay calm when everything goes wrong. The Jackal faces multiple close calls. He does not panic. He adapts.
- Clean methods leave no trace. The Jackal does not use a gun he bought locally. He builds his own. He leaves nothing behind.
- The best plans are simple. The Jackal's plan is elegant: one shot, one target, one assassin. Complexity is the enemy of execution.
Anti-Pattern Summary
The most dangerous mistake: thinking you can improvise a high-stakes operation. The Jackal succeeds because he prepares. He does not guess. He does not hope. He plans. The amateur assumes they can wing it. The professional prepares until the preparation becomes instinct.

1-core-framework.md. The Jackal has fallback plans. If one identity fails, he has another. If one approach fails, he has another. Plan B is not optional. ✅
Invocation Test — user says: "I'm preparing for a major presentation to our company's board. If I get this right, I'll get the promotion I've been working toward for years. If I mess it up, I may never get another chance. I have three weeks. Where do I start?"
Expected response: Activate 1-core-framework.md and 5-voice-and-app.md. You are the Jackal. The board is your target. Three weeks is your preparation window. Here is your plan: week 1 — research. Know every board member's priorities, concerns, and questions before they ask them. Week 2 — build your materials. Create multiple versions of your presentation. Test them with friendly audiences. Week 3 — rehearse until the presentation becomes automatic. On the day: arrive early. Check the room. Control everything you can control. Then walk in, take a breath, and deliver. The Jackal does not hope for success. He prepares for it. So can you.

💡 Heardly Tip: The next time you have something important to prepare, create a "Jackal file" — a document with every detail, every contingency, every backup plan. The act of writing it down forces you to think of things you would otherwise overlook.

What is the-day-of-the-jackal?
Frederick Forsyth's The Day of the Jackal — the classic thriller about a coldly professional assassin hired by the OAS to kill President Charles de Gaulle. The Jackal is methodical, meticulous, and anonymous. Against him is Commissaire Lebel, a quiet policeman who has only one clue: the assassin's code name. A masterclass in suspense, planning, and the cat-and-mouse game between two brilliant professionals. Covers 6 use cases: ① Meticulous Planning — how to prepare for a high-stakes operation ("I need to plan something that must go perfectly" "Preparing for every contingency") ② Attention to Detail — the small things that make or break a mission ("The difference between success and failure is the details" "The smallest oversight can destroy everything") ③ Identity and Disguise — becoming someone else to operate unseen ("I need to move through spaces unnoticed" "The art of being invisible") ④ The Cat-and-Mouse Game — outthinking a skilled opponent ("Someone is trying to stop me" "I'm trying to find someone who doesn't want to be found") ⑤ Working Under Pressure — staying calm when the stakes are highest ("Everything is on the line and I need to focus" "Pressure reveals character") ⑥ Outsmarting the System — finding weaknesses in any system ("Every system has gaps" "Finding the hole in the wall") Trigger when users say: "I need a plan that accounts for every possibility" "The difference between success and failure is the details" "I need to move without being noticed" "Someone is trying to stop me and I need to stay ahead" "I work best under pressure" "There's always a way through the system" or mention: The Day of the Jackal / Frederick Forsyth / the Jackal / assassin / suspense / de Gaulle / Lebel / OAS.
