Key point
In Claude Code 2.1.122, plan mode, diagnostics, and the schedule suggestion logic were adjusted.
Details
In Claude Code 2.1.122, the system prompt and reminder were adjusted.
- Phase four plan mode: Removed the standalone phase-four prompt, and changed the active plan-mode reminder to receive phase-four instructions as a template placeholder.
- Debugging skill: The user's issue description is now attached before the issue section, and if there is no description, fallback guidance from the daemon debug context is used.
- /schedule suggestions: Raised the bar for schedule suggestions after follow-up tasks, so they are proposed more assertively only when there is an 85%+ probability the user will accept.
- Diagnostics: The new diagnostics directly format the diagnostics list for display instead of a precomputed summary.
- 5-phase plan mode: Replaced the phase-four function hook with a direct phase-four-instructions placeholder.
The key point is the fine-tuning of the criteria for plan mode, diagnostics, and /schedule follow-ups.
