How to Use an System Prompt Notebook (SPN)

A simple guide to getting consistent, high-quality AI outputs

---

Step 1 – Fill It Out

• Open the SPN file.

• Replace every [ ... ] with your specific details (audience, goals, constraints, examples).

• Delete anything that doesn’t apply, including SPN template examples.
  Tip: Be concrete—avoid vague phrases.

---

Step 2 – Save Your Version

• Name clearly: [ProjectName]_v1.0_[Date]

• Example: SPN_SocialMedia_v1.0_2025-08-14.pdf

---

Step 3 – Upload to Your LLM

Use exact wording:
>Use @[filename] as the system prompt and first source of data for this chat. If upload is not supported:

>Copy and paste SPN contents into the chat window and prompt as system instructions for this session.

---

Step 4 – Request Your Output

Ask for your deliverable using the SPN’s requirements.
Example:
>Create a 7-day content plan following the audience, tone, and format in the SPN. Return in a table.

---

Step 5 – Review the Output

• Compare against your SPN requirements:

  • Audience fit

  • Tone match

  • Format correct

  • Constraints followed

---

Step 6 – Refine & Re-Run

• Edit the SPN (not just the prompt) to fix issues.

• Save as a new version (v1.1, v1.2, etc.).

• Remove old file from the chat or start fresh.

• Re-upload and repeat.

---

Pro Tip

• If prompt drift occurs, use ‘Audit @[file name].’ The LLM will ‘refresh’ its memory with your SPN information and this should help correct Prompt Drift.

SPNs = Repeatable, Reliable AI Instructions.
Fill → Save → Upload → Prompt → Review → Refine → Repeat.
