Enhanced Plan Mode Guidance

What: The ExitPlanMode tool now includes comprehensive guidance on handling ambiguous requirements and unclear implementation approaches.

Details:

• Added "Handling Ambiguity in Plans" section to help Claude identify when clarification is needed at OU8() at line 428198
• Claude will now proactively ask about:
• Multiple valid implementation approaches (e.g., architectural patterns)
• Library or framework choices
• Assumptions that could affect implementation
• Includes a new example demonstrating proper clarification workflow for authentication features
• Claude must now resolve ambiguities before proceeding with implementation

Impact: Users will experience fewer instances where Claude makes incorrect assumptions about implementation details. When requirements are unclear, Claude will ask targeted questions to understand the desired approach before writing code.

Evidence:

• v2.0.20: Basic ExitPlanMode documentation at OU8() at line 428188 with 2 examples
• v2.0.21: Enhanced ExitPlanMode documentation at OU8() at line 428198 with ambiguity handling section and 3 examples
