Contracts are prescription-strength legal devices. If you need terms for exchanging confidential information, don't be an idiot. Hire a lawyer. A good one will ask good questions. They may very well decide an RxNDA form meets your needs.
Do not put confidential information about you, your work, or your clients in issues or pull requests. Do not ask for legal advice on GitHub, or try to disguise requests for legal advice as general questions or hypotheticals. You don't want legal advice from anybody dumb enough to fall for that.
