FAQ
Is this free to use?
Yes. It is a static site with no backend, no account, and no paywall. Markdown source is open and MIT-licensed.
What patterns are covered?
Refine-Plan-Act loops, tool-calling patterns, context window management, error recovery, and parallelism. More patterns are added as they are vetted against real production use.
Can I submit a pattern?
Yes. Open a pull request with your Markdown card. Review checks that the pattern documents a real failure mode, not just a happy path.
