What problem this solves

Over-permissioned Claude Code setups that could lead to unintended modifications of sensitive files, configurations, or project directories due to ambiguous instructions or blanket tool access.

Summary

A proactive audit process to identify and tighten permissions for Claude Code, ensuring that the AI agent only has access to necessary files and tools, thereby preventing security risks and unintended actions.

Why it is useful

This workflow addresses a critical security and operational risk in AI development environments. It provides a clear, repeatable process for users to proactively manage Claude's access, preventing unintended data modification or exposure. By shifting reliance from the model's interpretation to explicit system boundaries, it enhances the safety and predictability of AI-assisted coding.

Workflow

1. Identify and review which tools are allowed globally versus per-project within your Claude Code setup.
2. Examine all CLAUDE.md files across your system for any embedded secrets or references to sensitive paths.
3. Determine and list specific files and directories that should be explicitly off-limits for Claude's access.
4. Implement stricter permissions and access controls based on the audit findings to limit Claude's scope.

Tools / artifacts

• Claude Code setup/configuration
• CLAUDE.md files

Validation signals

• Author's personal audit revealed three instances of over-permissioning.
• The argument that 'nothing bad happened yet' is insufficient justification for lax security, implying a proactive risk assessment.

Limitations

• Lacks specific commands or configuration examples for how to tighten permissions (e.g., exact CLAUDE.md syntax for exclusions, or methods for configuring tool access).
• Does not provide a checklist of common sensitive files/directories to look for.
