Dev Planning Kit

A screen map your AI can follow

Real screens, bundled with the menu structure (IA), feature notes, and done criteria. Any AI coding tool can build it through without guessing.

What changes with each way of building?

The same AI coding tool (Claude Code, Cursor, and others) takes a different amount of time, finishes differently, and fails differently depending on the planning you hand it.

When you ask an AI with no planning

  • Build timeFast at first, then fixes drag it out
  • CompletenessIt ends with screens and features still missing
  • Starting overThe AI guesses, and you rebuild again and again
  • DesignYou get the AI's default look
  • Launch prepTerms and launch prep are missing

When you ask with the Plandi Full setRecommended

  • Build timeA check up front, then fewer blockers
  • CompletenessThe planned screens and features all come out
  • Starting overIt follows the specs, so you redo less
  • DesignPick 1 of 3 drafts and apply it to every screen
  • Launch prepYou get a pre-launch checklist and a launch guide

Here is how the options compare. A fuller bar means it finishes sooner, comes out more complete, and fails less.

How building differs by option (a fuller bar means the AI gets stuck less)

Details
No planning
The first screen shows up fast, but finding and fixing what is missing takes a long time.
Interview only
What to build is settled, but deciding the screens as you go takes a long time.
Interview + IA
A screen list means less wandering, but you still decide the look and behavior while you build.
Full set
A kit check up front clears the blockers, then you build menu by menu from the screens and specs.
Completeness Gaps Screens Listed Complete
Details
No planning
You build whatever comes to mind, so screens and features are often left out.
Interview only
The big features land, but screens are easy to miss.
Interview + IA
You build from the menu and screen list, but button behavior and error handling are easy to miss.
Full set
Screens, specs, and a done checklist let you confirm each screen works before you finish.
Starting over Often Often Sometimes Rare

No planning
What the AI guessed is often not what you wanted, so you start over a lot.

Interview + IA
The structure is right, but guessed behavior still needs fixes.

We shaped this by building a real service from start to finish with the Full set's Dev Planning Kit. The checks we used then for features, privacy and terms, design, and completeness are in the kit.
