AI Coding Agent Kit: make Cursor and Claude Code stop wrecking your repo

Sound familiar?

The agent "fixes" a bug by editing the test until it passes.
A one-line change comes back as a 400-line diff with surprise refactors.
It invents an API that doesn't exist, confidently.
Every new session starts from zero and repeats last week's mistakes.
It runs cat .env to "debug" your config.

What changes after setup

One contract for every agent. A tight AGENTS.md with your exact commands, layout and no-go zones, which Cursor, Claude Code and Copilot all read.
Scoped rules, not prompt soup. 8 Cursor rules that only load when relevant (core, edit loop, tests, security, git, frontend, Go, TypeScript).
Safe by default. A Claude Code permission file that denies reading secrets, force-pushing and rm -rf, and allows your test and lint commands.
Proof before "done". The edit loop forces a test run and a what-changed, how-verified summary.
Sessions that resume. NEXT.md handoff notes, so tomorrow's agent picks up where today's stopped.
Know where you stand. A 20-point agent-readiness audit plus a zero-dependency scan script that scores your repo.

Questions

Which tools does it work with?

Cursor and Claude Code get dedicated files. AGENTS.md is read by Copilot, Codex, Gemini CLI, Windsurf and most other agents, so the core contract works everywhere.

Which languages and stacks?

Everything is stack-agnostic, with extra rules for Go, TypeScript and frontend code. You fill in your own commands in AGENTS.md.

How do I get it?

Pay via Stripe, and you're redirected straight to the download. The invoice arrives by email.

Can my team use it?

Yes, inside your own company. Please don't resell or republish the files.

Something not working?

Email [email protected] and you'll get help.
