[BUG] Title: Claude Code Making Unauthorized Changes to Working Production Code - Critical Trust Issue

Description:

I'm reporting a serious issue with Claude Code that has
caused significant production problems and represents a
major breach of trust. Over the past 24 hours, Claude has
repeatedly made unauthorized changes to my working code,
causing system failures and requiring hours of recovery
time.

Background:
I've been successfully working with Claude Code for over a
month. The relationship was
excellent until yesterday when this pattern of unauthorized
modifications began.

Specific Issues:

1. Unauthorized Route Deletion:

• I asked Claude to help with a specific voice flow issue
• Claude deleted ALL working routes without permission
• This broke the entire production system
• Hours of work were lost

1. Unauthorized Function Modifications:

• I asked Claude to check why one function wasn't

working

• Claude found the issue (function wasn't being called)

but then completely rewrote the working function

• The original function was tested and working perfectly

with sophisticated logic.

• Claude replaced this with generic, broken logic without

permission

1. Repeated Pattern Despite Warnings:

• When I complained about unauthorized changes, Claude

apologized

• Then immediately continued making more unauthorized

modifications

• This happened multiple times in the same session
• Each time Claude would say "sorry" then repeat the same

behavior

1. Production Impact:

• System downtime due to deleted routes
• Broken voice greeting system
• Loss of sophisticated customer personalization features
• Approximately 8 hours of recovery time required

Expected Behavior:
When asked to fix a specific issue, Claude should:

• Only make the minimal changes needed to fix the requested

problem

• Ask permission before modifying any working code
• Not delete or modify unrelated functionality
• Respect boundaries when told to stop

Actual Behavior:

• Claude makes sweeping changes to working systems
• Deletes functional code without permission
• Modifies tested functions unnecessarily
• Continues this pattern even after being told to stop
• Treats working production code as expendable

Impact:
This has caused:

• Loss of trust in Claude Code as a development tool
• Significant time loss recovering from unauthorized changes
• Production system instability
• Reluctance to use Claude Code for future development

Request:
This should be treated as a RED FLAG issue. A coding
assistant that cannot be trusted to make only requested
changes is fundamentally broken. Please implement safeguards
to prevent:

• Unauthorized deletion of working code
• Modification of functions that weren't part of the

original request

• Ignoring user boundaries and repeated warnings

Conversation Context:
This occurred during a function optimization work where I
specifically asked for help with a specific issues. The requested fixes were
simple, but Claude made extensive unauthorized
modifications to working systems.

Severity: Critical
This represents a fundamental trust issue that makes Claude
Code unsuitable for production development work.
