By name: zdupes description: Find duplicate or highly similar notes in the knowledge base using semantic search
/zdupes - Find Duplicate Notes
Scan S3 Vectors for semantically similar notes that might be duplicates or candidates for consolidation.
Usage
/zdupes # Default 85% threshold
/zdupes --threshold 90 # Custom threshold
Implementation
Run the duplicate detection command with proper AWS credentials:
isengardcli run --account 806230523044 -- bash -c '
export ZETTELKASTEN_BUCKET=zettelkasten-cajias
export ZETTELKASTEN_INDEX=knowledge-index
uvx --from ${CLAUDE_PLUGIN_ROOT} zk-dupes --threshold 85
'
What It Does
- Fetches all vectors from S3 Vectors
- For each vector, queries for similar vectors
- Reports pairs above the similarity threshold
- Groups results by similarity level (99%+, 95-99%, 90-95%, 85-90%)
When to Use
- After bulk imports to find accidental duplicates
- Periodically to consolidate similar knowledge
- When knowledge base feels bloated
- Before major reorganization
Interpreting Results
| Similarity | Meaning |
|---|---|
| 99%+ | Near-exact duplicates - consolidate or delete one |
| 95-99% | Very similar - review for redundancy |
| 90-95% | Related topics - consider linking |
| 85-90% | Thematically connected - may belong in same hub |
