What if your tests ran themselves?

02
Level 1

Self-Check.

Ask the AI to review its own work. Quick, catches obvious mistakes. Same blind spots though.

03
Level 2

Fresh Context.

Different model reviews without seeing the discussion. Breaks the echo chamber.

04
Level 3

Structural Tests.

Linter-style inspection. 'Does this JSON have all required fields? Are colors from the allowed set?'

05
Level 4

Pattern Tests.

Recurring problems, codified. AI keeps using implicit any? Write a test. It can't proceed until green.

And then there's the holy grail.

07
Level 5

Hooks. Tests run after every step.

Results inject into the next prompt. Closed loop. Self-correcting. No human needed.

What you're building

Leitplanken

/ˈlaɪ̯tˌplaŋkn̩/

Not walls that stop you. Rails that keep you on the road.

Hard gates for must-not-violate. Soft warnings for check-this.

Stop watching. Start automating.
