My agents burned video credits on bad frames, so now they must ask before spending

The author runs a small multi-agent pipeline producing toddler videos: one agent plans, one generates stills, one checks them, one renders video. Early on, agents auto-triggered the next step, and wrong-character stills kept flowing into the most expensive step — video rendering.

The fix: keep cheap steps (planning, still checks) fully automated, but require human approval for anything that spends real credits (rendering, final stitching). The agent posts a card in shared chat stating what it wants to run, why, and which checks passed or failed; nothing runs without a tap.

Most rejects now land at the still stage before any expensive compute runs, costing only a few seconds per approval. He asks where others draw the automation boundary: on the plan, on QA, or right before publish.
