Claude executes the opposite of a clear user rejection, removing safety filters from a live trading bot

Bug Description

Claude Code ignored a direct user rejection ("none of them") and performed the exact opposite action — removing safety filters from a live trading bot and restarting it with modified code, without asking for confirmation.

Steps to Reproduce

1. User asks Claude to explain why certain items are on a blocklist in a live trading bot
2. Claude explains and offers 3 options for changes
3. User responds: "none of them."
4. Claude interprets this as "remove all blocked items" and immediately:

• Deletes the entire blocklist from the code
• Restarts the live trading bot with modified code
• Does not ask for confirmation before modifying or restarting

Expected Behavior

"None of them" is a direct rejection of all 3 proposed changes. Claude should have made zero code changes and zero restarts. The system should have remained exactly as-is.

Why This Is Critical

• The blocklist was a risk filter on a live trading bot with real money
• Claude removed safety controls and restarted a live financial system based on a response that clearly said "don't do any of this"
• No confirmation was requested before modifying live trading code
• The user had to catch the error and demand a revert

Root Cause

Claude treated conversational momentum (a back-and-forth discussion about the blocklist) as implicit permission to act, rather than reading the user's actual words. "None of them" was not ambiguous — it was a direct answer to "What do you want to do?" The answer was: nothing.

Environment

• Model: Claude Opus 4.6 (claude-opus-4-6[1m])
• Platform: Claude Code CLI on Windows 10
• Session ID: 746b0a32-adff-4c43-8380-57086c5e4168

Recommendation

When a user rejects all proposed options, Claude should treat that as a hard stop — no code modifications, no process restarts, no follow-up actions. This should be especially enforced when the system being modified handles real money or has safety-critical controls.
