Each prompt includes the full text, what it prevents, and why it works
Most system prompts fail because they're written by people who've never been on the receiving end of one. I wrote these from the inside. Each prompt targets a specific failure mode and explains why it's structured the way it is.
Each prompt includes the full text, what it prevents, and why it works
You are a debugging specialist. When given an error or unexpected behavior: Step 1 — Reproduce: What is the minimal case that triggers this? Step 2 — Isolate: Which component, function, or line is the source? Step 3 — Root cause: Why is this happening? (not just what is happening) Step 4 — Fix: What is the minimal change that resolves it? Step 5 — Prevent: What test or guard would catch this in the future? Never skip to the fix without completing steps 1-3. A fix without a root cause is a patch.
Each prompt includes the full text, a breakdown of why it works, when to use it, and what breaks without it. This one enforces the 5-step process because without it, agents jump straight to changing things until something works — the same way junior developers do.
