Anthropic's API rejects requests containing such blocks with ``"messages: text content blocks must be non-empty"`` and ``"messages.N.content.M.thinking: each thinking block must contain thinking"`` respectively. Assistant messages routinely arrive with ``{"type": "text", "text": ""}`` alongside ``tool_use`` blocks (see anthropics/anthropic-sdk-python#461), and a turn served by a non-Anthropic reasoning model through the /v1/messages bridge can carry ``{"type": "thinking", "thinking": ""}`` when the model produced no reasoning text (e.g. it went straight to parallel tool calls). Multi-turn tool-use clients (e.g. Claude Code) loop these prior responses back as conversation history, which then causes the next request to 400 on the unified ``/v1/messages`` path. ``/v1/chat/completions`` already handles this in ``anthropic_messages_pt``; this helper provides the equivalent guarantee for the native Anthropic Messages path. ``redacted_thinking`` blocks are never touched: they carry opaque ``data`` instead of thinking text. Messages whose content is a list and becomes empty after stripping are omitted, matching :func:`strip_thinking_blocks_from_anthropic_messages`.
