Check your CRM board's health and clean up messy data — run a scored health check (missing fields, stalled deals, abandoned columns, automation gaps) as a report, or fix data in bulk (phone formats, missing emails, country codes, unowned deals, stale dates). Use when someone says "clean my CRM", "fix my data", "normalize my phone numbers", "fill in missing owners", "run a board health check", "audit my CRM board", "what's broken in my CRM", "what are the data gaps on my board", "board is messy", or "clean up before my kickoff call".

From the source SKILL.md

Two jobs in one skill for the recurring "my CRM is messy" pain (Sidekick's #1 negative-sentiment JTBD): - Health check (report-only): a scored structural audit of a CRM board — missing-data patterns, stalled groups, abandoned columns, automation gaps, and a 0–100 data-quality score — published as a diagnosis doc. No writes. - Cleanup (fix): audit the board for data gaps, let the user pick which to fix, then run a bounded, idempotent write loop.

What this skill does

Data Cleanup is a community-contributed Claude Code skill in the automation sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/data-cleanup/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use when someone says "clean my CRM", "fix my data", "normalize my phone numbers", "fill in missing owners", "run a board health check", "audit my CRM board", "what's broken in my CRM", "what are the data gaps on my board", "board is messy", or "clean up before my kickoff call".
