…nsport providers Claude Code v2.1.153+ injects role:"system" messages inline in the messages array (e.g. system-reminders). Anthropic-compat providers like Z.AI and GLM reject role:"system" in messages -- only user/assistant are accepted. This strips them from the messages array and merges their content into the top-level system prompt field. Also handle inline system messages in the OpenAI message converter so they are properly merged rather than silently dropped. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

Problem
Claude Code v2.1.153+ injects
role: "system"messages inline in the messages array (e.g., system-reminders injected between turns). Anthropic-compat providers like Z.AI and GLM reject these with HTTP 400 because they only acceptuserandassistantroles in messages.Changes
packages/cli/src/handlers/composed-handler.tsAfter step 4 (buildPayload), add a new step 4b that detects
anthropic-ssetransport format and strips anyrole: "system"messages from the payload's messages array. Their text content is merged into the top-levelsystemprompt field instead (appended to any existing system prompt).packages/cli/src/handlers/shared/format/openai-messages.tsAdd a handler for
msg.role === "system"in the message processing loop. System messages are merged into the existing system prompt (prepended or appended to the first system message) rather than silently dropped or causing a protocol error.Providers affected
