CRM Duplicate Killer — Find & Merge Duplicate Customer
Example session with this skill installed
Illustrative scenario: Prepare a merge review from supplied customer records, with no writes. C1 and C2 have the same verified external customer ID X123 and email alex@example.test. C1 has a phone from a verified billing source; C2 has a different phone from an undated import. C1 has an open support ticket; C2 has an open opportunity and marketing suppression. C3 shares the email but has customer ID X999 and is a separate branch account. No global survivorship policy or backup supplied. Propose dispositions, field decisions and safeguards.

Duplicate review
| Records | Identity evidence | Contradiction / context | Disposition |
|---|---|---|---|
| C1/C2 | Same supplied verified external ID X123 and email | Conflicting phone; connected ticket, opportunity and suppression | Strong candidate; reviewed merge plan only, pending source and policy validation |
| C1/C3 or C2/C3 | Shared email | Distinct customer ID X999 and supplied separate branch context | Do not merge on email similarity; preserve separate entity |
Proposed golden record
Proposed survivor: C1, subject to authorized policy and system validation. Retain stable source IDs and a C2 cross-reference. For phone, prefer the verified billing source over an undated import only after confirming source authority and recency; keep the alternate value and provenance in audit history where permitted. Do not invent a global rule from this single case.
Association and consent plan
Preserve C1’s support ticket and C2’s opportunity with their original identities/history. Confirm platform behavior for moving associations and avoid duplicating or losing activities. Preserve marketing suppression; a merge must not grant consent or remove a restriction. Confirm suppression scope and policy with the responsible owner. C3’s branch relationships remain separate.
Required review and dry run
Verify ID uniqueness semantics across systems and object types, compare contradictory fields and inspect the full cluster. Obtain backup/snapshot, approved survivorship policy, affected counts, rule version, sample and high-value/customer review, consent review and rollback plan. Run a preview of the proposed field and association changes before authorization.
Reconciliation checks
After an authorized merge, verify record counts, retained external IDs, opportunity and ticket links, ownership, suppression, history and downstream integrations. Monitor for false merges and repeated duplicate creation. No post-merge result is reported because no action occurred.
Decision state
C1/C2: review required; neither approved nor executed. C3: keep separate under supplied evidence. Backup, reviewer, execution permission and rollback reference are missing. No records were merged or deleted; no private enrichment or identity inference was performed.

About this skill
CRM Duplicate Killer specializes in customer identity resolution and duplicate-remediation planning. It examines contact, company, lead and explicitly scoped commercial records, determines whether they represent the same real-world entity, and prepares a reviewed golden-record and survivorship plan.
The workflow profiles identity keys, generates candidates, checks exact and fuzzy evidence, tests contradictions, resolves clusters and preserves associations, activities, consent, ownership and history. Shared mailboxes, branches, subsidiaries and moved-company cases are treated as potential false positives rather than automatic duplicates.
Outputs include confidence classifications, merge previews, field-level source decisions, reviewer requirements, rollback references and reconciliation checks. Live CRM actions depend on actual authorization and tool capability. Bulk merges/deletes require backup, snapshot, dry run, versioned rules, affected counts, reviews, rollback and validation. Similarity is never presented as certainty.

Similarity does not establish identity. Shared mailboxes/phones, branch or subsidiary relationships and source conflicts require review. Platform merge behavior and authoritative policies must be verified. No legal certification, invented identity or unreviewed destructive action; post-action success requires evidence.
