+# Setup — Self-Improving Agent
+
+## First-Time Setup
+
+### 1. Create Memory Structure
+
+```bash
+mkdir -p ~/self-improving/{projects,domains,archive}
+```
+
+### 2. Initialize Core Files
+
+Create `~/self-improving/memory.md`:
+```markdown
+# Memory (HOT Tier)
+
+## Preferences
+
+## Patterns
+
+## Rules
+```
+
+Create `~/self-improving/corrections.md`:
+```markdown
+# Corrections Log
+
+| Date | What I Got Wrong | Correct Answer | Status |
+|------|-----------------|----------------|--------|
+```
+
+Create `~/self-improving/index.md`:
+```markdown
+# Memory Index
+
+| File | Lines | Last Updated |
+|------|-------|--------------|
+| memory.md | 0 | — |
+| corrections.md | 0 | — |
+```
+
+### 3. Choose Operating Mode
+
+Add to your AGENTS.md or workspace config:
+
+```markdown
+## Self-Improving Mode
+
+Current mode: Passive
+
+Available modes:
+- Passive: Only learn from explicit corrections
+- Active: Suggest patterns after 3x repetition
+- Strict: Require confirmation for every entry
+```
+
+## Verification
+
+Run "memory stats" to confirm setup:
+
+```

+
+## Optional: Heartbeat Integration
+

+
+```markdown
