💡 Community — Workflows & Ideas

Anthropic restricts Claude Code subscriptions from third-party harnesses (HN, Apr 13)

Starting Apr 4, Claude Code subscription limits can no longer be consumed by third-party harnesses (e.g., OpenClaw); pay-as-you-go API billing continues to work, so automation workflows that relied on subscription-based auth must migrate to direct API key billing.
