When should I use The List Cleaner?

A fresh list export is full of duplicates and stale titles, and reps are about to waste a sequence on it. That's the diagnostic trigger. Once installed, ask Claude for the outcome ("dedupe and flag a raw list before it hits a sequence") and the skill kicks in automatically.

How does The List Cleaner work under the hood?

The List Cleaner is part of the SDR pack in Sid Chaudhary's gtm-skills repo. When invoked, Claude reads the SKILL.md, pulls your shared product-context (ICP, brand voice, scoring model), and produces a structured output. No prompt engineering on your side.

Do I need Claude Code to run The List Cleaner?

Claude Code is the fastest path since it auto-loads local skill folders. The same SKILL.md also runs in Claude Desktop and claude.ai Projects - upload the zip in Capabilities. See the install options below for both paths.

How is The List Cleaner different from just prompting Claude?

A skill is a folder with a SKILL.md file plus reference material - real methodology, frameworks, and benchmarks Claude loads on demand. A prompt is text you paste every time. With The List Cleaner installed, you ask for what you need in plain language and Claude runs the right process without you re-explaining it.

Q: Is The List Cleaner really free?

Yes. The full gtm-skills repo is MIT licensed on GitHub. Clone it, fork it, modify it. Running the install command (npx skills add sidchaudhary/gtm-skills/skills/sdr/the-list-cleaner) pulls it straight from GitHub into your project's .claude/skills/ folder. No signup, no build step, no gated tier.

Part of the SDR pack

This is one of 11 SDR skills. They chain - the order you run them in changes what you get, and running one in isolation usually means re-answering setup another skill already captured. 11 best Claude Code skills for SDRs walks the whole pack in the order the skills actually chain.

Install

Two ways to run it.

Pick your Claude surface. Both paths take under a minute.

Prefer one command? npx skills add sidchaudhary/gtm-skills installs the whole set via the community skills CLI. If you'd rather not run a third-party CLI, use either path below to install the ZIP directly.

claude.ai or Claude Desktop

Upload as a zip in Capabilities

Paid plan

Open Settings, then Capabilities
Turn on code execution if it isn't already on
Upload the .zip you downloaded

Requires a Pro, Max, Team, or Enterprise plan. Not available on the Free plan.

Claude Code

Drop the folder, it auto-loads

Any plan

Unzip the download
Drop the folder into ~/.claude/skills/ (or .claude/skills/ in a project)
Claude Code finds it automatically

Questions about The List Cleaner

Everything you need before installing, plus how the skill actually behaves once Claude picks it up.

Dedupes and flags a raw list - wrong titles, stale roles, wrong companies, broken data - before it goes into a sequence. It's a Claude Agent Skill - a folder with a SKILL.md file and reference material - so Claude loads the methodology on demand when you ask for what you need in plain language, instead of you pasting a template.
