Summary

What went wrong?

Openclaw stucked at "Agent failed before reply: anthropic is in cooldown (all profiles unavailable) (rate_limit)" because of Anthropic's rate limit

Steps to reproduce

1. Wrote up a task to do
2. Openclaw spawned 6 sub-agents and tried to spawn 6 more.

Expected behavior

Out-of-box default limit of sub-agents to spawn?

Actual behavior

For an hours got an error "⚠️ Agent failed before reply: All models failed (2): anthropic/claude-opus-4-5: Provider anthropic is in cooldown (all profiles unavailable) (rate_limit) | anthropic/claude-sonnet-4-5: Provider anthropic is in cooldown (all profiles unavailable) (rate_limit).

Spent a lot of time to find out how to fix it—only these commands helped
rm -f /home/ubuntu/.openclaw/agents/main/sessions/sessions.json
rm -rf /tmp/openclaw
openclaw gateway restart
