crm-data-cleanup skillA

crm-data-cleanup is agent-read markdown (skill) from onewave-ai/claude-skills: 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 merg.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns 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.
