+name: instinct-import
+description: Import instincts from teammates, Skill Creator, or other sources
+command: /instinct-import
+implementation: python3 ~/.claude/skills/continuous-learning-v2/scripts/instinct-cli.py import <file>
+---
+
+# Instinct Import Command
+
+## Implementation
+
+```bash
+python3 ~/.claude/skills/continuous-learning-v2/scripts/instinct-cli.py import <file-or-url> [--dry-run] [--force] [--min-confidence 0.7]
+```
+
+Import instincts from:
+- Teammates' exports
+- Skill Creator (repo analysis)
+- Community collections
+- Previous machine backups
+
+## Usage
+
+```
+/instinct-import team-instincts.yaml
+/instinct-import https://github.com/org/repo/instincts.yaml
+/instinct-import --from-skill-creator acme/webapp
+```
+
+## What to Do
+
+1. Fetch the instinct file (local path or URL)
+2. Parse and validate the format
+3. Check for duplicates with existing instincts
+4. Merge or add new instincts
+5. Save to `~/.claude/homunculus/instincts/inherited/`
+
+## Import Process
+
+```
+📥 Importing instincts from: team-instincts.yaml
+================================================
+
+Found 12 instincts to import.
+
+Analyzing conflicts...
+
+## New Instincts (8)
+These will be added:
+  ✓ use-zod-validation (confidence: 0.7)
+  ✓ prefer-named-exports (confidence: 0.65)
+  ✓ test-async-functions (confidence: 0.8)
+  ...
+
+## Duplicate Instincts (3)
+Already have similar instincts:
+  ⚠️ prefer-functional-style
+     Local: 0.8 confidence, 12 observations
+     Import: 0.7 confidence
+     → Keep local (higher confidence)
+
+  ⚠️ test-first-workflow
+     Local: 0.75 confidence
+     Import: 0.9 confidence
+     → Update to import (higher confidence)
+
+## Conflicting Instincts (1)
+These contradict local instincts:
+  ❌ use-classes-for-services
+     Conflicts with: avoid-classes
+     → Skip (requires manual resolution)
+
+---
+Import 8 new, update 1, skip 3?
+```
+
+## Merge Strategies
+
+### For Duplicates
+When importing an instinct that matches an existing one:
+- **Higher confidence wins**: Keep the one with higher confidence
+- **Merge evidence**: Combine observation counts
+- **Update timestamp**: Mark as recently validated
+
+### For Conflicts
+When importing an instinct that contradicts an existing one:
+- **Skip by default**: Don't import conflicting instincts
+- **Flag for review**: Mark both as needing attention
+- **Manual resolution**: User decides which to keep
+
+## Source Tracking
+
+Imported instincts are marked with:
+```yaml
+source: "inherited"
+imported_from: "team-instincts.yaml"
+imported_at: "2025-01-22T10:30:00Z"
+original_source: "session-observation"  # or "repo-analysis"
+```
+
+## Skill Creator Integration
+
+When importing from Skill Creator:
+
+```
+/instinct-import --from-skill-creator acme/webapp
+```
+
+This fetches instincts generated from repo analysis:
+- Source: `repo-analysis`
+- Higher initial confidence (0.7+)
+- Linked to source repository
+
+## Flags
+
+- `--dry-run`: Preview without importing
+- `--force`: Import even if conflicts exist
+- `--merge-strategy <higher|local|import>`: How to handle duplicates
+- `--from-skill-creator <owner/repo>`: Import from Skill Creator analysis
+- `--min-confidence <n>`: Only import instincts above threshold
+
+## Output
+
+After import:
+```
+✅ Import complete!
+
+Added: 8 instincts
+Updated: 1 instinct
+Skipped: 3 instincts (2 duplicates, 1 conflict)
+
+New instincts saved to: ~/.claude/homunculus/instincts/inherited/
+
+Run /instinct-status to see all instincts.
