Works with

  • Cursor
  • Claude Code
  • Codex
  • Windsurf
  • GitHub Copilot

The difference

Same prompt. Different output.

without a kit
// app/api/webhook/route.ts
const body = await req.json()
// TODO verify signature
await db.orders.insert(body)
console.log("key", process.env.LS_SECRET)
with security rules
// verify HMAC over the raw body first
const raw = await req.text()
if (!verifySignature(raw, sig, secret))
  return new Response("invalid", { status: 401 })
const event = WebhookSchema.parse(JSON.parse(raw))

Illustrative example of what the rules ask for. AI tools can still ignore rules, so kits also make the agent verify its work.

How it works

Three steps, about two minutes

  1. 1

    Pick a kit

    Rules for your stack, or a full starter project with every tool's files already installed.

  2. 2

    Drop in your tool's folder

    Copy cursor/, claude/, codex/, windsurf/ or copilot/ to your project root. Rules load automatically.

  3. 3

    Ship with commands

    Run /plan-feature, /fix-bug, /review-changes and /security-audit. The agent verifies its work with real checks.

Every tool, native format

Every file is generated from one master source and checked by a format validator, so the five versions never drift apart.

FAQ

Questions, answered

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.
