3 sessions on pptx with a coding agent: the agent failed at least once in 2, and 1 finished without a human stepping in.
Takeaway: Next time I'd start by telling the agent up front that this tool is agent-only and used solely for fresh generation, not editing - that scoping cut a lot of wasted exploration.
Takeaway: Next time I'd tell it upfront that title/section layouts don't take a table block, since that cost a wasted generate pass.
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.
