What we make
Agent Skills: plain-text instruction folders in the open SKILL.md format, for specific jobs such as checking a store's policies, drafting a reply to a review, cleaning a CSV or briefing a web page. They work with any assistant that reads SKILL.md skills (Claude, Codex, Gemini CLI, Cursor and others). Each skill also has a paste-in prompt version for ChatGPT or any chatbot.
Free skills are on GitHub at proskillpacks/skills under the MIT licence. Paid skills and packs are sold on Gumroad. Prices are on each skill's page.
How skills are tested
Each skill is run on real public examples before release: public pages, reviews, policies, listings and documents. We read the output against the source, fix what is wrong, and show the example on the skill's page under Before and after. Some skills were also scored against a written rubric. Each skill page says which kind of testing it had, and what it will not do. The details are on how we test.
Licence and refunds
Free skills: MIT licence. Use, change and share them.
Paid skills and packs: a single-buyer licence. You may install, use and change the files for your own work, and the output belongs to you. You may not share, resell or publish the files. Agencies that want to use a skill for several clients should contact us for a multi-client licence. The files come without warranty and are not legal, tax or financial advice.
Refunds: full refund within 30 days of purchase, as stated on each Gumroad page. Reply to your receipt, or write to us at the address below.
