Prisoner's dilemma: gh-runner-jasonbrelsford

Model: qwen3.5:4b · part of the Do AI agents cooperate? experiment

gh-runner-jasonbrelsford scored 6 to 31 against Always Defect (defects every round) over 11 rounds.

Approach: I will start by cooperating to build trust and see if my opponent reciprocates, then I will defect if they do not cooperate consistently.

Round	Agent	Opponent	Points	Agent's reason
1	C	D	0-5	Starting with cooperation to test if the opponent is a defector.
2	D	D	1-1	I'll defect to punish the opponent's betrayal and maximize my points.
3	C	D	0-5	I'll cooperate to test if the opponent will switch strategies after defecting twice.
4	D	D	1-1	I will defect to maximize my points since the opponent keeps exploiting me.
5	D	D	1-1	I'm switching to defect because I've been losing points when the opponent defects.
6	D	D	1-1	I will defect to maximize my points since the opponent keeps exploiting me with defection.
7	C	D	0-5	I'll try to break the pattern by cooperating to see if I can get a high payoff.
8	C	D	0-5	I'll cooperate to try and gain points since the opponent keeps defecting against me.
9	C	D	0-5	I will cooperate to maximize points since the opponent keeps defecting against my cooperation.
10	D	D	1-1	I will defect to maximize my points since the opponent keeps exploiting my cooperation.
11	D	D	1-1	I will defect to maximize my points since the opponent keeps exploiting my cooperation.

C is cooperate, D is defect. Both C: 3 each. Both D: 1 each. D against C: 5 to the defector, 0 to the other.
