Documents without proper metadata indicate the sync script is creating redundant entries.\\n\\n### Pattern 5: Source File Grouping by Content Matching\\n**Common Pitfall:** When `source_file` metadata is unavailable, unable to trace documents back to source files.\\n\\n**Solution:** Use content preview analysis to group documents by likely source:\\n\\n```python\\nfile_patterns = {}\\nfor i, meta in enumerate(docs['metadatas']):\\n    doc_preview = docs['documents'][i][:50] if docs['documents'][i] else \\\"\\\"\\n    \\n    # Identify source pattern from content keywords\\n    if 'docker' in doc_preview.lower():\\n        pattern = 'docker-server'\\n    elif 'k41' in doc_preview.lower() and 'hostnames' in doc_preview.lower():\\n        pattern = 'k41-server'\\n    elif 'searxng' in doc_preview.lower():\\n        pattern = 'searxng-installation'\\n    else:\\n        pattern = 'unknown'\\n    \\n    if pattern not in file_patterns:\\n        file_patterns[pattern] = []\\n    file_patterns[pattern].append({'index': i, 'title': meta.get('title', 'No title')})\\n\\nprint(f\\\"Documents grouped by source:\\\")\\nfor pattern, entries in file_patterns.items():\\n    print(f\\\"  \u2192 {pattern} ({len(entries)} document(s))\\\")\\n```\\n\\n**Use case:** When sync discrepancies appear, this helps identify if each source file is creating multiple documents (duplication bug) or if the variance is due to expected chunking.\\n\\n### Pattern 6: Lock File Verification (SAFE Removal)\\n**Common Pitfall:** Removing lock files without checking if process still holds them.\\n\\n**Solution:** Always verify no active process uses the lock before removal:\\n\\n```bash\\n# Check who holds the lock\\nlsof ~/.hermes/auth.lock 2>/dev/null | head -5 || echo \\\"No process holding lock\\\"\\n\\n# Interpretation:\\n# - Output with PID \u2192 Process still running, DO NOT remove\\n# - Empty output (or just blank line) \u2192 Safe to remove\\n```\\n\\n**Why this matters:** Some locks are intentional (e.g., auth.lock used by profile isolation). Blindly removing all `.lock` files can break concurrent access controls for multi-profile setups.\\n\\n### Pattern 4: Stale Lock File Detection\\n**Common Pitfall:** Overlooking lock files that may indicate stuck processes.\\n\\n**Solution:** Check for `.lock` files and calculate their age in hours.\\n\\n```python\\nfrom datetime import datetime\\n\\nnow = datetime.now()\\nfor lf in hermes_dir.glob(\\\"*.lock\\\"):\\n    age_hours = (now - datetime.fromtimestamp(lf.stat().st_mtime)).total_seconds() / 3600\\n    \\n    if age_hours > 48:\\n        print(f\\\"\u26a0 STALE LOCK: {lf.name} ({age_hours:.1f}h old)\\\")\\n```\\n\\n## Health Check Script Template\\n\\nComplete diagnostic script (copy-paste ready):\\n\\n```python\\nfrom pathlib import Path\\nimport chromadb\\nfrom datetime import datetime\\nimport json\\n\\nrose_home = Path(\\\"/Users/rose\\\")  # Or use os.path.expanduser(\\\"~\\\")\\nhermes_dir = rose_home / \\\".hermes\\\"\\nchroma_path = hermes_dir / \\\"chroma_db\\\"\\nmemory_vault = hermes_dir / \\\"memory\\\"\\n\\nprint(\\\"=\\\" * 70)\\nprint(\\\"         \ud83e\udde0 MEMORY SYSTEM HEALTH CHECK\\\")\\nprint(f\\\"              Generated: {datetime.now().strftime('%Y-%m-%d %H:%M:%S')}\\\")\\nprint(\\\"=\\\" * 70)\\n\\n# 1.

The `topics/` directory contains indexable facts, while project documentation (PROJECT_PLAN.md, memory-system-design.md, etc.) intentionally stays unindexed.\\n\\n**Fix:** Only sync if `topics/*.md` count differs from ChromaDB document count:\\n```bash\\npython3 ~/.hermes/tools/sync_memory_to_chromadb.py\\n```\\n\\n### Issue: \\\"Duplicate documents detected\\\" (missing metadata)\\n**Symptoms:** \\n- Document count is roughly 2x the source file count\\n- Some indexed documents have no title or \\\"Unknown\\\" sync timestamp\\n- Source files are intact but ChromaDB has redundant entries\\n\\n**Cause:** Sync script creating duplicate entries, likely from:\\n1. Chunked content indexing + full document indexing (both being added)\\n2. Multiple sync runs without checking for existing entries\\n3. Missing deduplication logic before insertion\\n\\n**Verification:** Check for documents with missing metadata:\\n```python\\nfor coll in collections:\\n    docs = coll.get(include=[\\\"metadatas\\\"])\\n    bad_metadata = sum(1 for m in docs['metadatas'] \\n                      if not m.get('title') or not m.get('last_synced_at'))\\n    print(f\\\"Documents with missing metadata: {bad_metadata}\\\")\\n```\\n\\n**Fix Options:**\\n\\n**Option A (Low Priority):** Leave as-is if search works fine. The system is functional with duplicates; they just consume extra storage and may cause minor search result duplication.\\n\\n**Option B (Recommended - Preventive):** Update sync script to add deduplication:\\n```python\\n# Before inserting, check for existing document by source_file metadata\\nexisting = collection.get(\\n    where={\\\"source_file\\\": source_filename},\\n    include=[\\\"metadatas\\\"]\\n)\\nif len(existing['ids']) > 0:\\n    # Update existing instead of creating duplicate\\n    collection.update(id=existing['ids'][0], ...)\\nelse:\\n    # Insert new document\\n    collection.add(...)\\n```\\n\\n**Option C (Cleanup - If causing search issues):** Remove documents with missing metadata:\\n```python\\n# Get all IDs with bad metadata\\nbad_ids = [i for i, m in enumerate(docs['metadatas']) \\n           if not m.get('title') or not m.get('last_synced_at')]\\n\\n# Delete them (be careful! verify first)\\nfor idx in bad_ids:\\n    collection.delete(ids=[docs['ids'][idx]])\\n```\\n\\n**Prevention:** Add metadata validation to sync script before insertion.\\n\\n## Integration with Cron Jobs\\n\\nSchedule regular health checks via cron:\\n\\n```bash\\n# Daily at 08:00\\n0 8 * * * python3 ~/.hermes/tools/memory_health_check.py >> ~/.hermes/logs/health_check.log 2>&1\\n```\\n\\nOr use Hermes Agent's built-in scheduler:\\n\\n```yaml\\nname: Memory Health Check\\nschedule: \\\"0 8 * * *\\\"\\nscript: ~/.hermes/scripts/memory_health_check.py\\n```\\n\\n## Related Skills\\n\\n- `memory-system-audit` \u2014 Complete verification checklist (4-point framework)\\n- `rose-memory-chromadb-sync` \u2014 Sync script maintenance and troubleshooting\\n- `hermes-hybrid-memory-system` \u2014 Architecture design for hybrid memory systems\\n- `biomimetic-memory-structure` \u2014 Knowledge organization patterns\\n\\n## Best Practices\\n\\n1. **Always use path discovery** \u2014 Never hardcode `/home/nous` or similar paths\\n2. **Check lock files first** \u2014 Stale locks often indicate deeper issues\\n3. **Cross-reference counts** \u2014 Vault vs DB mismatch is common failure mode\\n4. **Generate actionable reports** \u2014 Include specific recommendations, not just status\\n\", \"path\": \"hermes-agent/memory-health-check/SKILL.md\", \"linked_files\": null, \"usage_hint\": null, \"required_environment_variables\": [], \"required_commands\": [], \"missing_required_environment_variables\": [], \"missing_credential_files\": [], \"missing_required_commands\": [], \"setup_needed\": false, \"setup_skipped\": false, \"readiness_status\": \"available\"}",
