Opus 5 first look: breaks backward compatibility but shines when starting fresh

After a week of testing, the author finds Opus 5 incompatible with existing workflows, stopping early or missing instructions. However, starting from scratch yields much better results. Medium or low thinking effort works better. The author calls it a 'poor man's Fable' and will likely use it only when Fable tokens run out.
