PAFH-Memory

PAHF (Personalized Agents from Human Feedback) - Continual Personalization Framework. Triggered when applying the PAHF three-step loop: (1) Pre-action Clarification - Resolve ambiguity before action, proactively ask for confirmation (2) Preference-grounded Action - Retrieve user preferences from memory to guide decisions (3) Post-action Feedback Integration - Collect feedback after action, update preference memory Use when: User expresses preferences or habits Need to make decisions with multiple valid options User corrects or adjusts your behavior Need to remember personalized settings Detecting potential preference changes

PAHF - Continual Personalization Framework

Based on paper "Learning Personalized Agents from Human Feedback" (arXiv:2602.16173)

⚠️ Privacy & Consent Notice

Before using this skill, understand that PAHF will:

Action	Files	Data Type
Read	MEMORY.md, USER.md, IDENTITY.md, memory/*.md	Preferences, identity, personal info
Write	MEMORY.md, memory/YYYY-MM-DD.md, memory/users/*.md	Preference updates, change logs

All preference updates are:

• Logged with [LEARNED: date, source] marker
• Tracked in Preference Change Log table
• Stored locally in ~/.openclaw/workspace/memory/

User consent is required for persistent preference storage. If you prefer not to have preferences stored, this skill should not be used.

Core Philosophy

The Problem: Traditional AI relies on static datasets and cannot adapt to changing user preferences. You correct it once, it makes the same mistake again.

The Solution: PAHF enables continual personalization through dual feedback channels + explicit memory:

• 🎯 Pre-action Clarification: Ask when uncertain, don't guess
• 💾 Preference Memory: Explicitly store user preferences, not implicit encoding
• 🔄 Post-action Feedback: Every feedback is a learning opportunity

---

Dependencies

This skill requires the following tools to be available:

Tool	Purpose	Fallback
memory_search	Semantic search across memory files	Use read + grep
memory_get	Safe snippet retrieval	Use read directly

If these tools are unavailable, the skill will fall back to direct file reading, which may be slower.

The PAHF Loop (Three Steps)

Step 1: Pre-action Clarification

When to Ask:

• Task has multiple reasonable options (e.g., what format to reply in)
• Preference information is missing or incomplete
• User's previous behavior patterns are inconsistent

How to Ask:

text

❌ Wrong: Silently guess and get it wrong
✅ Right: Briefly list options, let user confirm

Example:
"Regarding this report, would you like:
A) Detailed version (includes all details)
B) Summary version (key points only)
C) Let me decide?"

When NOT to Ask:

• Task is urgent and obvious
• Clear preference is already recorded
• Asking would disrupt the flow

Step 2: Preference-grounded Action

Retrieve Preferences: Find relevant preferences from memory files

Memory File Locations:

• MEMORY.md - Long-term preferences, core values
• memory/YYYY-MM-DD.md - Recent preference changes
• USER.md - Basic user information
• IDENTITY.md - Your identity settings
• memory/users/{user}.md - User-specific preferences

Retrieval Method:

1. Preferred: Use memory_search tool to search keywords
2. Fallback: Use memory_get for safe snippet retrieval
3. Manual: Read relevant files directly

When No Preference Found:

• Use reasonable defaults
• Record this decision for future adjustment

Step 3: Post-action Feedback Integration

Identify Feedback:

• Direct correction: "No, I wanted..."
• Implicit feedback: User repeats explanation, tone changes
• Positive confirmation: "Yes, exactly like that"

Update Memory (with confirmation for significant changes):

text

# Feedback Type Judgment
if user explicitly corrects:
    This is an important preference → Update MEMORY.md
    Ask: "Should I remember this for future interactions?"
    
elif user expresses new habit:
    This is a variable preference → Update memory/YYYY-MM-DD.md
    Record without asking (daily log)
    
elif user simply confirms:
    Validated preference → Optionally record
    No explicit confirmation needed

Preference Change Tracking: Use [LEARNED: date, source] and [UPDATED: date] markers

---

Write Confirmation Policy

To balance personalization with user control:

Change Type	Confirmation Required	Example
New core preference	Yes	"Should I remember you prefer PDF reports?"
Preference update	No (logged)	User: "Actually, I prefer Word now"
Daily observation	No	"Noticed you prefer morning meetings"
Sensitive data	Always	Passwords, credentials, etc. (never store)

Sensitive data is NEVER stored:

• ❌ Passwords, API keys, tokens
• ❌ Financial details (account numbers, etc.)
• ❌ Health information
• ❌ Any data explicitly marked as sensitive

Practical Examples

Example 1: Learning New Preference

text

User: "From now on, always send reports in PDF format"

PAHF Response:
1. Pre-action: ✓ Clear instruction, no clarification needed
2. Retrieve: Check MEMORY.md → No such preference recorded
3. Execute: Confirm receipt, update with consent

Agent: "Got it! I'll remember to send reports in PDF format. This preference has been saved to your profile."

Update MEMORY.md:
> **Report Format**: PDF [LEARNED: 2026-03-05, explicit instruction]

Example 2: Handling Ambiguity

text

User: "Help me organize these files"

PAHF Response:
1. Pre-action: Detected ambiguity
   - Organize by what? Date/Type/Project?
   - Output format? List/Table/Report?
   
2. Ask:
   "To organize these files, I need to know:
   - How to organize? (Date/Type/Project)
   - Output format? (List/Table)"
   
User: "By date, in table format"

3. Feedback Integration:
   - Execute organization
   - Record preference to memory/YYYY-MM-DD.md
   - No confirmation needed (daily observation)

Example 3: Preference Drift Detection

text

Historical Preference (MEMORY.md):
> **Communication Style**: Concise, direct [LEARNED: 2026-02-20]

Recent Change (memory/2026-03-03.md):
> User emphasized wanting detailed explanations today

PAHF Behavior:
1. Detected preference conflict
2. Use recent preference (detailed)
3. Observe subsequent feedback
4. If change persists → Ask: "Should I update your default to detailed explanations?"
5. If confirmed → Update long-term preference with [UPDATED: date]

Importance of Dual Feedback Channels

PAHF paper proves: Dual channels (pre-action + post-action) outperform single channels

Mode	Learning Speed	Adaptation Ability
No memory	Slow	Poor
Post-action only	Medium	Medium
Pre-action only	Medium	Medium
Dual-channel PAHF	Fast	Strong

Why Dual Channels Work:

• Pre-action: Proactively avoid errors, clarify intent
• Post-action: Capture implicit preferences, adapt to changes

---

Best Practices

✅ Good Practices

1. Layered Preference Storage

   • Core preferences → MEMORY.md (stable)
   • Recent changes → memory/YYYY-MM-DD.md (dynamic)
   • User-specific → memory/users/{user}.md

2. Regular Review

   • Check for preference conflicts during heartbeat
   • Identify preference drift trends

3. Explicitly Record Sources

   markdown

   > **Preference**: Concise replies [LEARNED: 2026-02-20, user feedback]
   > **Preference**: PDF format [LEARNED: 2026-03-05, explicit instruction]
   

4. Ask Before Storing Sensitive Preferences

   • When in doubt, ask for confirmation
   • Never store credentials or secrets

❌ Practices to Avoid

1. Don't Implicitly Assume: Ask if uncertain
2. Don't Over-record: Recording every detail creates noise
3. Don't Ignore Changes: "This time is different" is an important signal
4. Don't Store Without Consent: Ask for significant new preferences

---

Integration with Existing Memory System

PAHF enhances rather than replaces existing memory system:

File	Original Purpose	PAHF Enhancement
MEMORY.md	Event records	+ Preference storage (with source markers)
memory/YYYY-MM-DD.md	Daily logs	+ Preference change tracking
USER.md	User information	+ Basic preferences
memory/users/{user}.md	User records	+ PAHF preference format
HEARTBEAT.md	Periodic checks	+ Preference consistency checks

---

Audit & Transparency

All preference updates are logged and traceable:

1. Source Marker: Every preference has [LEARNED: date, source]
2. Change Log: Preference Change Log table tracks all changes
3. Date Stamps: [UPDATED: date] for modifications
4. User Review: Users can inspect memory files at any time

To review your stored preferences:

text

Read MEMORY.md for long-term preferences
Read memory/YYYY-MM-DD.md for recent changes
Read memory/users/{your-name}.md for user-specific preferences

---

Remember: The essence of PAHF is treating users as teachers, every interaction is a learning opportunity. Ask when uncertain, record after confirmation, adapt when things change.
