+description: Export instincts for sharing with teammates or other projects
+command: /instinct-export
+---
+
+# Instinct Export Command
+
+Exports instincts to a shareable format. Perfect for:
+- Sharing with teammates
+- Transferring to a new machine
+- Contributing to project conventions
+
+## Usage
+
+```
+/instinct-export                           # Export all personal instincts
+/instinct-export --domain testing          # Export only testing instincts
+/instinct-export --min-confidence 0.7      # Only export high-confidence instincts
+/instinct-export --output team-instincts.yaml
+```
+
+## What to Do
+
+1. Read instincts from `~/.claude/homunculus/instincts/personal/`
+2. Filter based on flags
+3. Strip sensitive information:
+   - Remove session IDs
+   - Remove file paths (keep only patterns)
+   - Remove timestamps older than "last week"
+4. Generate export file
+
+## Output Format
+
+Creates a YAML file:
+
+```yaml
+# Instincts Export
+# Generated: 2025-01-22
+# Source: personal
+# Count: 12 instincts
+
+version: "2.0"
+exported_by: "continuous-learning-v2"
+export_date: "2025-01-22T10:30:00Z"
+
+instincts:
+  - id: prefer-functional-style
+    trigger: "when writing new functions"
+    action: "Use functional patterns over classes"
+    confidence: 0.8
+    domain: code-style
+    observations: 8
+
+  - id: test-first-workflow
+    trigger: "when adding new functionality"
+    action: "Write test first, then implementation"
+    confidence: 0.9
+    domain: testing
+    observations: 12
+
+  - id: grep-before-edit
+    trigger: "when modifying code"
+    action: "Search with Grep, confirm with Read, then Edit"
+    confidence: 0.7
+    domain: workflow
+    observations: 6
+```
+
+## Privacy Considerations
+
+Exports include:
+- ✅ Trigger patterns
+- ✅ Actions
+- ✅ Confidence scores
+- ✅ Domains
+- ✅ Observation counts
+
+Exports do NOT include:
+- ❌ Actual code snippets
+- ❌ File paths
+- ❌ Session transcripts
+- ❌ Personal identifiers
+
+## Flags
+
+- `--domain <name>`: Export only specified domain
+- `--min-confidence <n>`: Minimum confidence threshold (default: 0.3)
+- `--output <file>`: Output file path (default: instincts-export-YYYYMMDD.yaml)
+- `--format <yaml|json|md>`: Output format (default: yaml)
+- `--include-evidence`: Include evidence text (default: excluded)
