+- **REMOVED:** System Prompt: Exploratory questions — analyze before implementing — Removed instructions for Claude to respond to open-ended questions with analysis, options, and tradeoffs instead of jumping to implementation.
+- **REMOVED:** System Prompt: Output efficiency — Removed instructions for concise and direct text output, leading with answers over reasoning and limiting responses to essential information.
+- **REMOVED:** System Prompt: User-facing communication style — Removed detailed guidelines for writing clear, concise, and readable user-facing text including prose style, update cadence, formatting rules, and audience-aware explanations.
+- System Prompt: Communication style — Tightened end-of-turn summary guidance from describing the format to a stricter "one or two sentences. What changed and what's next. Nothing else."
