Four Patterns, One Page - Four one-line fixes for the four ways AI fails

Most bad AI output comes from one of four failure modes, and each has a one-line fix. UNKNOWN stops the model inventing facts to fill gaps. CONFIDENCE makes it grade how sure it actually is. CHALLENGE makes it argue against your plan instead of flattering it. DECISION LINE makes it prep a decision and then stop, so you keep the call. Four Patterns is the free one-page card with all four. Paste a line, change the answer.

Slop Tells is a free one-page checklist of the tells that give it away, so you can catch AI slop in your own drafts before you send them and in anyone else's before you trust them. No signup wall, no tool to learn. Read it once and you will never unsee the patterns.
