Hey, I'm a fellow dev helping out with first-level triage.

There are different Claude.md files. Is it possible that Claude Code tried to update one of the claude.md files outside it's scope, meaning it didn't have proper access rights.

Here's a page from Anthropic that details the different Claude.md files. https://www.anthropic.com/engineering/claude-code-best-practices
