## FAQ
### What is KitQuarry?
KitQuarry sells AI coding kits: rule files, skills/slash commands and tested starter projects for Cursor, Claude Code, Codex, Windsurf and GitHub Copilot. Each kit is generated from one master source into every tool's native format.

### Which tools are supported?
Cursor, Claude Code, Codex, Windsurf and GitHub Copilot. Cursor gets .mdc rules, Claude Code gets CLAUDE.md + .claude/rules + skills, Codex gets AGENTS.md + .agents/skills, Windsurf gets .windsurf/rules + workflows, and Copilot gets copilot-instructions + instructions + prompt files.

### What does 'tested' mean?
Every starter project passes its own checks before we zip it. The agent and SaaS starters pass lint, typecheck, tests and build from a clean npm ci. The Godot starter passes a headless parse, run and smoke test on Godot 4.3 and 4.7.2. Generated rule files are validated against each tool's documented format limits.

### Is it a subscription?
No. Every kit is a one-time purchase, and v1.x updates are included.

### What is in the bundle?
The Complete Toolkit ($99) contains all four paid kits: Rules Pack, AI Agent Starter, SaaS Starter and Godot Game Dev Kit. Bought separately they cost $131.

### Is there a free version?
Yes. The free sampler has the core, security and agent-workflow rules, plus the /plan-feature and /review-changes skills, in every tool format.

### How do I install a kit?
Unzip it, then copy your tool's folder contents to your project root. Starter kits come with every tool's files already in place. Each tool has its own docs page.

### Do the rules guarantee correct AI code?
No. Rules are context, not enforcement, and models can still ignore them. The kits reduce common mistakes and tell the agent to verify its work with real commands (tests, typecheck, build) so mistakes show up fast.

### Can I use the kits in commercial and client projects?
Yes, you can use them in unlimited projects of your own and your clients'. You may not resell or redistribute the kit files themselves. See the terms.

### What is your refund policy?
See the refund policy page. It is a draft until the store goes live.
