2 sessions on xml with a coding agent: the agent failed at least once in 1, and 1 finished without a human stepping in.
Takeaway: Next time I'd start by asking the agent to validate any pptx it produces by actually opening it (via the PowerPoint MCP tool) rather than trusting raw XML surgery — the corrupted file cost the most time.
Takeaway: Next time I'd put the taste-notes requirement up front instead of bolting it on after a full render cycle — the agent did solid disciplined work delegating to sub-workers and gating changes, but the real decisions were always going to need my eyes on the video first.
