From 1fd318c9e3a9cfccf4a6e420bd6647f8b89dbabc Mon Sep 17 00:00:00 2001 From: empty Date: Tue, 30 Dec 2025 12:01:07 +0800 Subject: [PATCH] feat(engine): add faction power system with event triggers MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Add FactionData model with power and members fields - Add FactionEventResult model for faction event responses - Add faction field to AgentState - Implement faction classification based on emotion - Add faction event triggers (festival/panic) when power >= 5 - Update StepResponse to include triggered_faction_event - Add tests for new faction system 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 --- engine-python/app/engine.py | 6 +- engine-python/app/factions.py | 126 +++++++++++++++++++++++++++---- engine-python/app/main.py | 7 +- engine-python/app/models.py | 22 +++++- engine-python/app/state.py | 8 +- engine-python/tests/test_step.py | 39 ++++++++-- 6 files changed, 181 insertions(+), 27 deletions(-) diff --git a/engine-python/app/engine.py b/engine-python/app/engine.py index 86b4bbc..4a04c6a 100644 --- a/engine-python/app/engine.py +++ b/engine-python/app/engine.py @@ -2,12 +2,14 @@ from __future__ import annotations from typing import List, Optional, Tuple from .models import ( WorldState, AgentState, Event, Action, Emotion, Weather, -
