Startpacks

Startpacks is an open-source library of starter packs for AI coding tools: Cursor rules, Claude Code skills, AGENTS.md files and prompts tailored to your stack, plus a marketplace for premium packs and bundles.

Startpacks provides skills, rules, definitions, starter agents, and prompts for AI coding agents. Its packs target particular engines, stacks, project types, and developer roles, with a focus on making agents work test-first. The site offers free packs, individual prompts, and discounted bundles. It helps users find ready-made guidance and files for tasks such as code review, testing, game development, and building websites or apps. Users choose a pack based on its target stack, genre, app type, or role, and can review what it contains. Free packs require an account; paid packs are purchased through Stripe Checkout as a one-time payment with no subscription. Users download the files and copy items such as AGENTS.md, rules, and skills into a repository. They can download again later and receive update notices. The site is for people using AI coding agents across software projects, including website, app, and game development, as well as roles such as testing, security review, and code review. Packs are organized by category and describe their contents so users can choose guidance for a particular project or workflow. Its offerings include both multi-file packs and self-contained prompts for specific jobs.
