Duplicate Record Review
Purpose
Identify likely duplicate profiles or companies using available record evidence.
When to use this skill
- De-duplicating a merged or re-scraped list
- Catching the same company under different names
- Preventing double outreach to one contact
- Producing a reviewable merge plan
When not to use this skill
- The records share no comparable identifiers
- You need an irreversible automatic merge (always review)
- The list is already known to be unique
Required inputs
- A list of company or profile records
Optional inputs
- Match keys to prioritize (domain, email)
- A confidence threshold
- Fields that must match exactly
Rules
- Describe matches as likely unless an exact deterministic key matches.
- Report match confidence and the evidence behind it.
- Never auto-merge; recommend and flag for review.
- List conflicting fields explicitly.
- Prefer the most complete record as the survivor.
Process
- Compare records on available keys.
- Group likely duplicates.
- Assess confidence and list matching/conflicting fields.
- Recommend a survivor and merges.
- Set manual-review status.
Output format
Return one record per duplicate group with the following fields:
- duplicate_group
- match_confidence
- matching_fields
- conflicting_fields
- merge_recommendation
- manual_review_status
Validation
- Confirm only exact key matches are called certain.
- Confirm conflicts are listed for each group.
- Confirm no merge is performed automatically.
Limitations
- Without unique keys, matches are probabilistic.
- Distinct entities can share names; review before merging.
