Install in Cursor

Buy a pack (or the bundle) via Creem checkout above. After payment, download the zip from the confirmation email or delivery page.
Unzip the download. Open the pack folder you need.
Copy .cursorrules and AGENTS.md into your project root (next to package.json, pyproject.toml, or go.mod).
Open the project in Cursor. Start an Agent/Chat session—the rules load with the workspace.
Optional: merge into existing rules or split into .cursor/rules/ with path globs. Details are in each pack’s README.

VS Code / Copilot: keep AGENTS.md at the root, or mirror bullets into .github/copilot-instructions.md.

FAQ

How do I buy?

Use the Buy buttons above (Creem handles payment and tax). If checkout is blocked while the store is under review, wait for Creem approval and try again. Questions: [email protected].

What’s the license?

After purchase you may use the pack files in personal and commercial projects. You may not resell or redistribute the pack contents as a competing rules product. See our Terms.

Will this overwrite my existing rules?

Only if you replace your files. Prefer merging sections. Each README explains Cursor root rules vs .cursor/rules/.

Do you offer refunds?

Digital downloads: contact us if the zip is corrupted or the wrong pack was delivered. See Terms for the full policy stub until counsel-reviewed text lands.

Are the rules original?

Yes. Written for Craftlane—actionable checklists and pitfalls, not scraped docs or copyrighted tutorials.
