Claude Code Deployments Accumulate Excess Permissions

A developer auditing their Claude Code tool-permission setup found three access grants that had no business being there: read/write on .env files, access to production config directories, and at least one additional blanket grant accumulated through repeated "approve all" clicks during onboarding. The audit walks through a minimal-access review process, arguing that most Claude Code installations are silently over-permissioned because the default setup flow nudges users toward broad approvals without surfacing the cumulative exposure. The risk compounds in long autonomous sessions where Claude can chain tool calls across an extended workflow without re-prompting for confirmation. Essentially: (Anthropic, Claude Code users) have a permission hygiene gap baked into the default setup experience. - Three specific over-grants identified: .env file access, production config directory access, and one additional undisclosed grant - Commenters in the thread independently confirmed similar findings in their own setups - Chained tool calls in autonomous sessions mean a single over-permissioned grant can propagate across multiple actions without a human checkpoint The broader pattern is that AI coding tools optimized for frictionless onboarding are producing security configurations that developers would reject outright if they saw them spelled out at setup time.
