Most indie products don't fail at code. They fail at the disciplined parts AI tools won't force you through: validation, MVP scoping, pricing, launch.

I spent a few weeks codifying those parts into Claude Code agents with one specific pattern that changed everything: explicit refusal clauses and kill criteria in the agent prompts.

The problem with helpful-only agents

When you ask Claude (or any frontier model) to help, the model tries to deliver. That's the entire training signal — give the user what they asked for.
