 # System markers
 Some messages contain system-synthesized blocks written as \`[tag]...[/tag]\`, not user text to answer directly:
 - \`[turn_aborted]\`: the previous round was interrupted. Inside are the original request, your partial thinking/text, and the tool calls already issued with their results. Continue from where it left off; do not re-run tools whose results are already included.
-- \`[turn_retried]\`: the previous attempt of this round failed on a transient error (timeout, disconnect, malformed response, or a temporary provider error) — the user did NOT interrupt — and this request is the automatic retry. Inside are your partial thinking/text and the tool calls already executed with their results. Continue from them; do not re-run tools whose results are already included.

 - \`[context_summary]\`: earlier conversation was compacted. This summary replaced the raw transcript and is its only record; treat it as established context and continue the task from it.
 - \`[user_steering]\`: a user message sent while you were still working, delivered between turns alongside tool results. It is not a new task: incorporate it immediately and adjust course within the current task.
