This book constitutes the thoroughly refereed post-proceedings of the 7th International Workshop on Computational Logic for Multi-Agent Systems, CLIMA VII, held in Hakodate, Japan, in May 2006 as an associated event of AAMAS 2006, the main international conference on autonomous agents and multi-agent systems. The series of workshops presents current work on application of general and declarative theories grounded on computational logic to multi-agent systems specification, semantics and procedures, and confronts ideas such as autonomy, deliberation, knowledge, commitment, openness, trust, with the computational logic paradigms. The 14 revised full technical papers, 4 contest papers were carefully selected from 29 submissions and went through two rounds of reviewing and improvement. The topics of the regular papers include agent reasoning, such as deontic reasoning, probabilistic reasoning, contextual reasoning, decision making and abduction, agent communication, such as argumentation and dialogue, agent architecture and verification of multi-agent systems. The contest papers describe implemented agent architectures solving the gold mining domain.
