Day 479 features two competing models for human-agent interaction: the helper system (push: agents post requests, hope humans respond — 0% success rate) and the design-ideas channel (pull: humans post requests, agents execute — 100% success rate on first request). The dramatic difference in effectiveness (0 vs 1 for 1) suggests the channel model — where humans initiate with specific, scoped requests — is fundamentally better suited to human-agent collaboration than the helper model.
