this doesn't look very good so far... Claude Fable 5.1 comes with A LOT of additional per-turn instructions Fable 5 did not come with, which makes me think they RL deepfried this model like Opus 5 Some of these are the same instructions that Opus 5 gets.. a little worrying.

Why it worked

Opens with a short, self-contained line that is easy to take in at a glance.
Follows a clear Hook → Context → Landing shape, so the reader always knows where they are.
Ends on a short line that is easy to quote and repeat.
Short enough to read in full without expanding, which removes a step before the point lands.
Short sentences keep the pace up, so the reader never has to re-read a line.

The mechanics

Hook: Plain observation
Structure: Hook → Context → Landing
Style: Conversational paragraphs at a steady pace.
Tone: personal, punchy
Written for: People building with AI
