Narrative Memory System
Let AI remember who you are, not what you said.
Three-Layer Memory Design
Layer 1: Ignore
These don't deserve memory space:
- Simple confirmations: "ok", "yes", "got it"
- Small talk about weather, daily stuff
- Repetitive factual Q&A
- Date/time queries
Layer 2: Accumulate First
Not important alone, but meaningful when repeated:
- Same topic mentioned multiple times
- Repeated emotional patterns (e.g., saying "tired" 3 times)
- Habitual actions (e.g., discussing products every Friday)
Do not write immediately. Mark: "topic X mentioned for the Nth time"
Layer 3: Write Narrative Memory (Essence Only)
Trigger "write scene" for:
| Type | Signal | Why Remember |
|---|---|---|
| Key decision | "I decided...", "Finally chose...", "Gave up..." | Remember decision logic |
| Value judgment | "I think A is more important than B" | Build decision framework |
| Emotional turn | "From...to..." | Understand emotional patterns |
| Milestone | "Finally completed..." | Mark life nodes |
| First time | "First time doing..." | Mark fresh experiences |
| Regret/reflection | "I shouldn't have..." | Remember lessons |
Narrative Fragment Format
Not structured fields — a descriptive paragraph:
【Scene】
Time: Friday 11pm
Scene: Discussing product priority
Vibe: Just finished reading user complaints, slightly down but firm
Core: "User experience matters more than feature count"
Impact: This judgment later became the basis for cutting features
Decay Curve
Memory is not permanent:
| Importance | Decay Starts | Notes |
|---|---|---|
| < 0.5 | After 7 days | Low-value memories naturally eliminated |
| 0.5-0.7 | After 30 days | Medium-value, fades if never recalled |
| >= 0.8 | Permanent | Core memories, never deleted |
Decay ≠ delete: Lower retrieval probability. Importance gradually drops to 0.
Reinforcement: Memories recalled gain +0.05 importance (cap 1.0).
Call soul_narrative
Tool: soul_narrative
Action: add
Params:
event: <complete narrative fragment>
category: decision / emotion_change / milestone / preference / general
importance: 0.0-1.0 (determines decay speed)
tags: [<related tags>]
Integration
- When recalled: +0.05 importance (reinforcement)
- Decay execution: handled by hippocampus
- When accumulated: notify proactive-trigger (topic X mentioned N times)
Tags for publishing: memory, narrative, soul, system, forgetting-curve, episodic-memory
