Sales Skills by Mutiny is a free set of 8 Claude skills for sales. They learn how you write and sell from your CRM, email and calls, then do the work around every meeting: the prep, the follow-up, the CRM update, the check-in, and the pricing proposal, business case or deal room your buyer asked for. Built by the team at Mutiny.
2-minute install · 10-minute setup · free, no signup
Example
Build my sales profile
You, your voice and how you sell
In email. You’re brief and warm. You open with “Hey Maya,” and close with “Talk soon,”
A line that’s all you. “Want to make this easy to say yes to.”
A bit about your deals
What you sell
A RevOps platform, to RevOps leaders at 200 to 2,000 person software companies
A typical deal
About $70k, about 7 weeks
What’s working
Emails that end on a specific question got a reply 9 of 12 times, against 3 of 14 without one
Fix anything I got wrong, or just say “looks right.”
Nothing to memorize. Talk to Claude like you normally would. These phrases start each one. Click a phrase to copy it.
Around every meeting
Mutiny setup. Run this first Learns how you write and sell from your CRM, calls and email.
Mutiny daily brief. Your day, what changed since yesterday, and what to do first.
Mutiny meeting prep. A 60-second brief for one call: who’s on it, what they want, what you still don’t know.
Mutiny follow-up. Writes the follow-up in your voice and the CRM update from what was said. Nothing goes out until you approve it.
Mutiny check-in. Finds deals going quiet and drafts one short, specific check-in for each. Never “just checking in.”
Customer-ready pages, built from your calls
Mutiny pricing proposal. One or two options inside the budget your buyer named, with rollout, terms and the next step.
Mutiny business case. What your champion takes to their exec: the cost today, the future state, and the math shown.
Mutiny deal room. One page for the whole buying group: what we heard, pricing, security docs and a shared plan.
A plugin adds all 8 skills to Claude at once. There are two parts: connect our marketplace, then add the plugin from it. New skills show up as we ship them.

Can’t add plugins, or use ChatGPT, Copilot or Gemini? The same skills are free as plain files on GitHub. In Claude Code, run claude plugin marketplace add MutinyGTM/mutiny-sales-skills.
1.
In Claude, start a new conversation and type Build my sales profile.
2.
Setup reads your CRM, calls and email, shows you what it learned, and asks a couple of quick questions. About 5 to 10 minutes.
3.
It gives you a few short profile files and walks you through saving them in a Claude project called My Deals. A project is a workspace that keeps files for every chat inside it.
That’s it. Every conversation in My Deals now knows how you sell, how you write, and how your team runs deals. Leading a team? Setup also makes team files your reps can add.
Your first 10 minutes
Don’t stop at the install. After your next call, run one skill on a real deal. The follow-up is the best first test, because you’ll know right away whether it sounds like you.
That’s what setup is for. It reads the emails you sent to buyers and keeps your greeting, your sign-off, your length and the phrases that are yours, with real examples for each situation. Every draft is written from that file. If something sounds off, tell Claude and say “Refresh my sales profile.”
The skills are instructions for Claude, not a pipe to us. Your CRM, email and calls stay connected through Claude’s own connectors. The plugin runs no code and sends nothing to Mutiny, and your sales profile is saved in your own Claude project. Check with your company that your Claude account is set up so Anthropic doesn’t train on your data.
It works from what’s in the tools you connect, and every skill is told to leave out anything it can’t trace to a call, an email or your CRM. Prices come only from your own pricing, and customer stories only from your own website. AI can still get things wrong, so read every draft before it goes to a buyer. Nothing is sent for you.
Any CRM or recorder with a Claude connector: HubSpot, Salesforce, Attio, Gong, Fireflies, Granola and more. You can check yours in Claude’s connector directory. If yours isn’t listed, the skills still run. You’ll paste in the transcript or deal notes.
There’s no catch. It’s free, with no signup or email gate, and you can remove it anytime. We build Mutiny, the sales assistant built for customer-facing work. It does all of this without being asked: it takes notes on every call, drafts the follow-up in your voice, and hosts the pages it builds so you can see who opened them. If these skills are useful to you, you’re who we built Mutiny for, and it’s free to start.
Yes. Each rep adds the plugin and runs setup. A sales leader’s setup also makes team files, so every rep follows one process in their own voice.
Each rep still has to remember to run it. When you want the follow-up, prep and CRM update drafted after every call for every rep, see Mutiny for teams.
Yes. The plugin is for Claude, but the same 8 skills are free as plain files in the GitHub repo. Paste one into a Custom GPT, a Copilot agent or a Gem and use the same phrases.
