Skill body
Dedupe Leads
Remove duplicate rows from a CSV of leads or contacts.
Steps
- Read
${CLAUDE_CONFIG_DIR:-$HOME/.claude}/skills/landbase-dedupe-leads/references/matching-rules.mdto understand how rows are matched and which record is kept. - Confirm the input CSV path with the user. The file should have a header row;
the
email,company, andnamecolumns are used for matching when present. -
Run the dedupe script that ships with this skill:
python3 "${CLAUDE_CONFIG_DIR:-$HOME/.claude}/skills/landbase-dedupe-leads/scripts/dedupe.py" <INPUT.csv> -o <OUTPUT.csv>If you omit
-o, the script writes<INPUT>.deduped.csv. - Report the summary the script prints (input rows, output rows, removed) and the path to the output file.
The script uses only the Python standard library — nothing to install.
