The original Claude Opus 4 model does not support strict tools, which
crewai 1.14.6 requires. With the current default, the booking flow
(buyer) and any manager-LLM-driven crews silently fail with:
Error code: 400 - {'type': 'error', 'error': {'type':
'invalid_request_error', 'message': "'claude-opus-4-20250514' does
not support strict tools."}}
Switching to claude-sonnet-4-5-20250929 (parity with DEFAULT_LLM_MODEL)
resolves it. Discovered during EOD smoke test 2026-05-29 (ar-r82f.15).
