Plan Mode: Cannot exit when user selects 'Info only' - no plan needed

Bug Report: Plan Mode Exit blocked despite 'Info only' response

Environment

• Claude Code CLI
• Model: Opus 4.5
• OS: macOS

Issue

When in Plan Mode, if the user answers a clarifying question indicating they only wanted information (not
implementation), Claude correctly understands no plan is required. However, when Claude tries to call
ExitPlanMode, the system blocks it with:

No plan found. Please write your plan to the plan file first.

Expected Behavior

If the user indicates they only wanted information (not implementation), ExitPlanMode should allow exiting
without requiring a plan file, since there's nothing to plan.

Suggested Fix

• Allow ExitPlanMode to accept an optional parameter like no_plan_needed=true
• Or: Detect when user response indicates 'info only' and auto-exit plan mode
• Or: Provide a 'Cancel Plan Mode' option separate from 'Exit Plan Mode'

Reproduction Steps

1. Enter plan mode (e.g., by asking about a feature)
2. Claude asks clarifying question with option like "Only info / No implementation needed"
3. User selects that option
4. Claude tries to exit plan mode → Blocked with "No plan found"

Actual Output

⏺ User answered Claude's questions:
⎿ · Möchtest du einen RAG-Agenten bauen? → Nur Info

⏺ [Claude provides informational response...]

─────────────────────────────────────────────────────────
Ready to code?
Here is Claude's plan:
No plan found. Please write your plan to the plan file first.

2. No, keep planning

The user selected "Info only" but the system still demands a plan file, creating a dead-end.
