Artifact database reads and writes now honor the setting that confines file access to your working directories.

The artifact database tool's file-backed reads and writes (db_op paths, file_path resolution) now route through the same working-directory checks as other file access, so blockReadsOutsideWorkingDirectories also constrains which local files can be used as data sources or destinations for artifact database operations. The read/write sub-tool is only enabled when its gating check returns true.

Since it was published

The entry above is what we published on the day. These lines were added later, as Anthropic's own pages caught up, and they sit beside the original rather than replacing it.

Added since A small documentation edit on How Claude remembers your project touched a line naming blockReadsOutsideWorkingDirectories after this was published. When you set it in a project's `.claude/settings.json` or `.claude/settings.local.json`, Claude Code honors it under the same [workspace trust rule as hooks in settings files](/docs/en/permissions#what-runs-before-you-trust-a-folder). Whil… memory see the edit
Confirmed since Anthropic's documentation has since written up blockReadsOutsideWorkingDirectories, on Claude Code changelog. * Fixed Bash commands with two directory changes, a subshell, or a `cd`+`git` chain skipping the prompt under `permissions.blockReadsOutsideWorkingDirectories` in bypass and auto mode changelog see the edit
