25I have a difficult task in this workspace and I want you to run it as an eval-driven improvement loop.

26 Before changing anything:

27 - Read `AGENTS.md`.

28 - Find the script or command that scores the current output.

29 Iteration loop:

30 - Make one focused improvement at a time.

31 - Re-run the eval command after each meaningful change.

32 - Log the scores and what changed.

33- Inspect generated artifacts directly. If the output is visual, use `view\_image`.

34 - Keep going until both the overall score and the LLM average are above 90%.

35 Constraints:

36 - Do not stop at the first acceptable result.

37- Do not revert to an earlier version unless the new result is clearly worse in scores or artifacts.

38- If the eval improves but is still below target, explain the bottleneck and continue.

41 - log of major iterations
