This is a python implementation of the IAM Policy Expander Minimizer.

Install:

pip install iampoliciesgonewild

Usage:

from iampoliciesgonewild import expand_policy
from iampoliciesgonewild import minimize_policy

policy = {
        "Statement": [{
            "Action": ["swf:res*"],
            "Resource": "*",
            "Effect": "Allow"
          }]
      }
      
expanded_policy = expand_policy(policy=policy)
>>> Start size: 131. End size: 286
print(expanded_policy == {
        "Statement": [{
            "Action": [
              "swf:respondactivitytaskcanceled",
              "swf:respondactivitytaskcompleted",
              "swf:respondactivitytaskfailed",

            ],
            "Resource": "*",
            "Effect": "Allow"
          }]
      })
>>> True

minimized_policy = minimize_policy(policy=expanded_policy, minchars=3)
