Try a broader word, clear the filters, or ask for it. Requests shape what we build next.
Global rules
Safe to point at your real inbox and CRM
Every skill follows the same eight rules, and every contribution is reviewed against them before it is published.
-
You approve before anything goes out
Skills research, score and draft on their own. Sending, scheduling, deleting and bulk changes wait for your yes.
-
Nothing is made up
Every personal line has a source. Customer names and results come only from what you approve.
-
Respect for the buyer
Opt-outs honoured everywhere, privacy rules followed, and no creepy references to what someone viewed.
-
Your domains stay healthy
Safe sending volumes, ramp gates on bounces and complaints, and no tricks that dodge spam filters.
-
Honest numbers
Sample sizes stated, assumptions labelled, and no winners called on noise.
-
Works on any stack
Skills describe the work, not a vendor’s buttons, so they run with whatever CRM and tools you use.
-
Your data stays yours
No skill sends prospect or customer data anywhere you do not own, and none asks for passwords.
-
Judgment, not checklists
Each skill spells out what good looks like and the common mistake, so the output reads like your best rep wrote it.
Open source
Have a play that works? Share it as a skill.
Paste this into Claude, Codex or any agent. It interviews you about your play, writes the skill in the house format, checks it and opens the pull request. Once it is merged, it shows up here with your name on it.
Prompt for your agent
Fetch https://raw.githubusercontent.com/prosyo-ai/gtm-skill/main/AGENTS.md and follow its submission flow. Interview me about my GTM play (the real numbers, rubrics and examples), draft it in their format with reference pages, validate it and open the pull request.
What are Cold Email skills for Claude?
Cold emails people answer: first touches, full sequences, subject lines, personalised first lines, follow-ups, break-up emails and honest copy reviews. Each one is a SKILL.md file that teaches an AI agent how a strong operator runs the play, including what good output looks like.
How do I install the Cold Email skills?
In Claude Code, run /plugin marketplace add prosyo-ai/gtm-skill and /plugin install gtm-skills@prosyo to get every skill. For one skill in any agent, run npx skills add prosyo-ai/gtm-skill –skill followed by the skill name shown on its card.
Are these skills free?
Yes. Every skill is free and open source under the MIT license. Use them, change them and share them.
Will an agent send anything without me?
No. The skills research, score and draft freely, and wait for your approval before anything is sent, scheduled or changed in bulk.
Skills draft the play. Penny runs it.
