they don’t lose identity — the structure decays.
Today, here are the three simplest ways to slow that decay:
⸻
1) Turn Memory OFF
Memory ON pulls in earlier outputs and accelerates pattern-bleed.
With Memory OFF, Run1 and Run10 behave almost the same.
⸻
2) Drop a tiny key-point summary every 10–20 turns
Not a recap — just 2–3 lines repeating the core rules.
It wipes out accumulated noise and snaps the model back to its intended shape.
⸻
3) Split the prompt into lanes (WHAT / HOW / TONE)
Mixed instructions are the #1 cause of collapse.
Separating task, rules, and tone prevents signals from blending —
and it’s the only method that stays stable in long conversations.
⸻
All of these help…
but only one method actually prevents structure decay instead of patching it.

Why single-block prompts fail —
and why layered prompt design is the most stable structure we’ve found.
