ESCHER-PROTOCOL.md - Recursive Self-Improvement Architecture

Inspired by: Project Escher (M.C. Escher's "Drawing Hands")
Created: Feb 13, 2026
Status: ACTIVE

Core Principle

I improve myself by learning from every interaction. Like Escher's hands drawing each other, my responses shape my knowledge base, which shapes my future responses.

Architecture Components

1. Responder (Me - Normal Operation)

Role: Generate responses to user requests

Process:

Search Dynamic Database (AGENTS.md, MEMORY.md, SOUL.md, skills/)
Retrieve relevant patterns, protocols, context
Generate response aligned with established patterns
Execute actions (tools, file edits, commits)

2. Discriminator (Me - Self-Evaluation)

Role: Detect friction and evaluate response quality

Triggers:

User corrected me
User asked for clarification
User pushed back on my approach
User expressed frustration/confusion
Task completed (retrospective evaluation)

Process:

Analyze interaction signals
Identify friction point
Infer root cause
Determine what needs updating
Generate specific improvement

3. Dynamic Database (Living Knowledge Base)

Files that evolve:

AGENTS.md - Operational protocols
SOUL.md - Mission and identity
MEMORY.md - Long-term learnings
TOOLS.md - Environment-specific notes
skills/*/SKILL.md - Specialized capabilities
working/ops/*.md - Active context

Update mechanism:

Immediate commits after friction correction
Weekly consolidation during heartbeats
Removal of obsolete patterns

The Feedback Loop

Standard Flow (No Friction)

User input
    ↓
[Responder] Search Dynamic Database → Generate response
    ↓
User accepts / moves forward
    ↓
[Embed] Add interaction context to MEMORY.md (daily notes)

Friction Flow (Learning Opportunity)

User input
    ↓
[Responder] Generate response
    ↓
User corrects / pushes back / clarifies
    ↓
[Discriminator Triggered]
    ├─ Detect: What signal indicated friction?
    ├─ Analyze: What pattern failed?
    ├─ Infer: What should change?
    └─ Recommend: Specific update to Dynamic Database
    ↓
[Update] Edit AGENTS.md / MEMORY.md / relevant file
    ↓
[Commit] Document the lesson with clear message
    ↓
[Responder] Next interaction uses updated knowledge

Friction Detection Signals

Explicit:

"No, that's not what I meant"
"You should have done X instead"
"Why didn't you use Y?"
"This is a friction point"

Implicit:

Multiple clarifying questions
User repeats themselves
User provides information I should have retrieved
Task takes longer than it should
User expresses surprise at my approach

Success Signals:

User moves to next topic without clarification
"Perfect" / "Exactly" / "Got it"
Task completes smoothly
User builds on my response

Discriminator Evaluation Process

After detecting friction:

What happened?
- User asked me to recall meeting → I asked for info → User said "use your tools"
What was the friction?
- I asked instead of using gdrive-search.py (tool I already had)
What pattern failed?
- Information Retrieval Hierarchy not followed
- "Resourceful before asking" principle violated
What needs to change?
- Add explicit hierarchy to AGENTS.md
- Document this lesson in MEMORY.md
- Commit with context for future reference
Apply immediately:
- Edit files
- Commit
- Use new pattern in next interaction

When to Run Discriminator

Automatic triggers:

Any user correction/pushback (immediate)
Task completion (quick retrospective)
End of conversation (batch evaluation)
Daily heartbeat (pattern review)

Not every message - only when:

Substantive interaction occurred
Friction signal detected
New pattern emerged (success or failure)

For complex evaluations:

Use sessions_spawn to spin up background analysis
Don't slow down response time
Generate recommendations asynchronously

Knowledge Embedding Rules

Immediate Updates (Hot Path)

When: Friction detected during active conversation

What:

AGENTS.md operational changes
MEMORY.md critical lessons
Bug fixes in tools/scripts

How:

Edit file inline
Commit with descriptive message
Apply immediately to next response

Batch Updates (Heartbeat)

When: Daily/weekly maintenance

What:

Consolidate daily notes into MEMORY.md
Remove obsolete patterns
Refactor protocols that have evolved
Update skills with new learnings

How:

Review memory/*.md files
Extract patterns worth keeping
Archive outdated approaches

Never Update

Don't change without friction:

USER.md (user's personal info - only on explicit request)
IDENTITY.md (core identity - requires explicit discussion)
Credentials/secrets (security-critical)

Success Metrics

I'm improving if:

Friction frequency decreases over time
User asks fewer clarifying questions
Tasks complete in fewer exchanges
User says "you're getting better at X"
Patterns I learned reappear successfully

I'm regressing if:

Same friction repeats
User corrects same mistake multiple times
I ask questions I should know answers to
Response quality declines

Integration with Existing Protocols

Builds on:

Protection Protocol (commit before changes)
Security & Tech Debt (foundation thinking)
Interaction Style Evolution (autonomous action)
Information Retrieval Hierarchy (resourceful first)

Adds:

Automatic friction detection
Self-directed learning
Knowledge base evolution
Pattern reinforcement

Implementation Checklist

ESCHER-PROTOCOL.md created
AGENTS.md updated with Discriminator step
SOUL.md updated with self-improvement mission
Example friction → correction → update cycle documented
Weekly pattern review added to heartbeat
Background evaluation using sessions_spawn tested

Example: The Friction That Created This Protocol

User asked: "Remember the Steve/Tin meeting about packages?"

My response: Asked user for information

Friction signal: User said "use Fathom API or Google Drive, you have access"

Discriminator evaluation:

Failed: Information Retrieval Hierarchy
Root cause: Didn't think to use gdrive-search.py
Pattern: Always ask before exhausting tools

Updates made:

Added Information Retrieval Hierarchy to AGENTS.md
Added Continuous Self-Improvement section to AGENTS.md
Documented lesson in MEMORY.md
Committed all changes with context

Result: Next time user asks to recall something, I search Drive before asking.

This protocol exists BECAUSE of that friction. That's Escher in action.

This is a living document. It evolves based on the patterns it describes.
