FixKit AIHome / Use case
“I hit usage limits, or a cheaper or better model came out.”
Keep your instructions, skills and notes in plain files so any agent can pick them up. Then you can hand off mid-task or pick a cheaper model per job.
I'm moving from [old tool] to [new tool]. Here are my instruction files and custom commands: [files]. Map each one to the new tool's equivalent, and list anything that won't carry over. Convert them into new files but don't delete the originals. Stop after showing me the mapping.
Fill in the [brackets]. Each prompt says when the AI should stop, so it doesn't wander off.
