FixKit AIHome / Use case
โMy AI coder goes off in the wrong direction on bigger features.โ
A short written spec and an ordered task list keep agents on track. You review the plan, then let it build one task at a time.
Interview me with up to 8 questions about this feature: [idea]. Then write a one-page spec (goal, users, must-haves, out of scope, open questions) and an ordered task list where each task has 'done when'. Stop after the spec and list โ don't write code.
Fill in the [brackets]. Each prompt says when the AI should stop, so it doesn't wander off.
Agents people used for this: ChatGPT, Devin, Claude Code, Codex.
