Unclear It is not clear whether edits to ARCHITECTURE.md are now blocked, need your approval, or are only marked as protected.
What
Claude Code keeps a fixed list of edit rules for files that need special care. The list already covered CLAUDE.md, CLAUDE.local.md, AGENTS.md and .mcp.json. It now also includes Edit(//**/ARCHITECTURE.md), which matches a file named ARCHITECTURE.md in any folder.
Why
If your project has an ARCHITECTURE.md file, Claude may now handle edits to it as it handles edits to CLAUDE.md, for example by asking you first.
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
