Cleans up CRM data from HubSpot, Salesforce, Pipedrive, Zoho, Close, Attio, or any CRM CSV export. Finds duplicate contacts and companies with fuzzy matching (not just exact email), normalizes emails, phones to E.164, names, domains, states, and countries, flags stale, invalid, role, and test records, finds broken contact-company associations, and produces a reviewable merge plan plus import-ready files without touching the live CRM. Use this skill whenever the user wants to dedupe, find or…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# CRM Data Cleanup This skill turns a messy CRM export into a merge plan a human can check, plus files that are ready to import. It works the same way for any vendor, because every CRM exports CSV. Duplicate cleanup usually fails in one of three ways. Exact-email matching misses most duplicates. Merging on shared inboxes like `info@` fuses different people into one. And a merge overwrites good values with blanks, losing history that can't be recovered. Most CRM merges **can't be undone**, so this skill never merges anything itself. It plans, a human approves, and the CRM's own merge tool does the merging. ## Files - `scripts/dedupe.py`: the dry-run engine: normalize, block, score, cluster, pick a survivor, merge fields. Needs `pandas` and `rapidfuzz`. Uses `phonenumbers` if it's installed. - `scripts/evaluate.py`: scores a run against a labeled truth file (pairwise precision and recall). - `assets/fixture/`: 41 synthetic contacts and 14 companies with planted duplicates, plus `truth.csv`. - `references/field-standards.md`: normalization rules, state and country codes, lifecycle stage mapping, and flag meanings. …

How to install
mdr add onewave-ai/claude-skills/crm-data-cleanup@sha256:227b32ed2dae1163The line at the top of this page pins the label git:20260923.ebdb76d, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
