This weekend I started using Garry Tan's Claude skill called Gstack. It adds several skills to Claude Code that helps with the design and build process.
Right now the one I'm using the most is /plan-ceo-review and /plan-eng-review
The CEO Review takes a feature or change request and looks at it from multiple angles asking "Is this really what we need or do we need to expand/contract the scope to hit what the user ACTUALLY is looking for?" And it's doing a fantastic job of helping me hash out all the extra questions I forget to ask.
The ENG Review takes the same approach but it looks at the gaps in the technology that are going to come up during the build and it gets resolutions for them before the build starts.
Then it compiles a comprehensive plan for the agent to build out. If you have time and you aren't using it yet, give it a try. It's significantly helped with my app quality!!
If you decide to try it, let me know how it goes!
