Claude Code 2.1.207 system prompt updates
Notable changes:
1) Claude no longer gets told that <system-reminder> tags in messages/tool results are injected by the harness (not user text). This weakens guidance on how to interpret those tags, increasing the chance Claude treats them like user-provided content instead of system-side annotations.
2) Claude now sees an extra Bun hot-update warning about import.meta.hot.accept placed ahead of the main security/harness rules. This adds non-instructional, task-specific noise that can divert attention or trigger irrelevant troubleshooting guidance in otherwise unrelated conversations.
