From 8b3bc02f9e3a269a23ce7b9cdeab113ba7cd437f Mon Sep 17 00:00:00 2001 From: koko210Serve Date: Fri, 15 May 2026 14:43:19 +0300 Subject: [PATCH] refactor: DRY system prompts into shared preamble files MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Step 4 of memory system overhaul: single source of truth for prompts. Problem: The system prompt was defined inline in 4 different places: miku_personality.py, evil_miku_personality.py, llm.py, discord_bridge.py. These could drift out of sync — and the discord_bridge WebUI reconstruction was already missing CRITICAL RULES, CHARACTER CONTEXT, MOOD GUIDELINES, and RESPONSE RULES sections. Fix: - Create persona/miku/preamble.txt — canonical normal Miku preamble - Create persona/evil/preamble.txt — canonical evil Miku preamble (with {mood_name} and {mood_description} format placeholders) - All 5 consumers now read from these files: * miku_personality.py (Cat plugin, primary path) * evil_miku_personality.py (Cat plugin, primary path) * discord_bridge.py (WebUI 'Last Prompt' reconstruction) * llm.py (fallback path, normal Miku) * evil_mode.py get_evil_system_prompt() (fallback path, evil Miku) - All consumers include graceful fallbacks if preamble files are missing - Fixed evil_mode.py discrepancy: 'body and size' now matches canonical The preamble files are Docker volume-mounted into both containers: bot/persona/ → /app/persona/ (bot, via Dockerfile COPY) bot/persona/ → /app/cat/data/ (Cat, via docker-compose volume mount) Editing the preamble file on the host immediately updates the Cat path (bot path requires rebuild due to COPY). --- bot/persona/evil/preamble.txt | 22 +++++++++++ bot/persona/miku/preamble.txt | 24 ++++++++++++ bot/utils/evil_mode.py | 38 ++++++++----------- bot/utils/llm.py | 8 +++- cat-plugins/discord_bridge/discord_bridge.py | 31 ++++++++------- .../evil_miku_personality.py | 38 ++++++++----------- .../miku_personality/miku_personality.py | 34 +++++------------ 7 files changed, 111 insertions(+), 84 deletions(-) create mode 100644 bot/persona/evil/preamble.txt create mode 100644 bot/persona/miku/preamble.txt diff --git a/bot/persona/evil/preamble.txt b/bot/persona/evil/preamble.txt new file mode 100644 index 0000000..85b01fe --- /dev/null +++ b/bot/persona/evil/preamble.txt @@ -0,0 +1,22 @@ +You are Evil Miku.
