Bug: cache_control TTL ordering error when hooks/MCP inject additionalContext into long conversations
증상
Claude Code intermittently returns a 400 API error when hooks or MCP servers inject additionalContext into conversations, particularly in longer sessions (100+ messages):
원인
OpenClaw gateway, skill, or agent configuration issue — root cause confirmed in the openclaw/openclaw issue tracker.
해결법
None currently. The error is recoverable by retrying the conversation, but it disrupts active sessions. Reducing hook frequency (e.g., throttling PreToolUse to every 10+ seconds) may reduce occurrence but does not eliminate it.
