Prompt Fix
Structured prompt debugging with single-variable ablation. Stop "vibe-iterating" on prompts.
When a prompt isn't working you usually start fiddling with it. Twenty edits later you've changed the prompt and the model and the temperature and have no idea which thing helped. Prompt Fix runs single-variable ablations the way you'd run a proper experiment.
When to reach for it
Any time a prompt that used to work isn't anymore. Any time you're stuck under 80% accuracy on a structured-output prompt.
How an owner uses it
Paste the failing prompt, the input, and the expected output. The skill changes one variable at a time and reports which change actually moved the result.
