- Environment
- Claude Code 2.x + Python
Handled mixed date formats, duplicate keys and unit inconsistencies in a 60k-row export, with a change log of every transformation.
Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works
- Installs cleanly 5/5
- Triggers reliably 4/5
- Output vs. baseline 9/10
- Docs & honesty 4/5
What it does
Deduplication, type coercion, format normalization — with a change log so you can verify nothing was silently mangled. The audit trail is what separates this from ad-hoc cleaning.
Install
Copy the skill folder into ~/.claude/skills/ and attach the messy file.
Skills live in ~/.claude/skills/ (global) or .claude/skills/
(per-project). Restart Claude Code after installing.
