About ax

ax the retro loop for AI coding agents Make your agent learn. Turn every agent session into a better next run. Every sub-agent you spawn finishes its work and disappears. Whatever it figured out - which command failed three times before the right one, which file actually mattered, which approach to skip - dies with it. The next sub-agent rediscovers it from scratch. Your own next session does too. watches every session your harness runs, spots the mistakes it repeats, and turns them into small, repo-specific fixes you review and apply - one at a time. Under the hood, it's the loop that closes before the session ends. A Stop hook fires at session-end (main or sub-agent), asks the agent for a structured retro (tried · worked · failed · next), and indexes the result as a typed experiment in a local graph. Friction patterns become proposals you triage. Accepted proposals become experiments with t+7 / t+30 / t+90 verdicts. The next session reads what worked. What did this sub-agent learn? Which experiments are still open? Which skills earned their keep? What did that branch cost in tokens? answers these by reading what already happened.
