What

The eval sandbox documentation now warns that the harness judges a run from the child process's output and files, which a shell-granted process running as you can also reach. Scores from an untrusted suite run with --allow-tools Bash, or any other grant that can execute code, should be treated as advisory unless the run had operating-system-level isolation.

Details

Added since A small documentation edit on Test plugins with evals touched a line naming --allow-tools after this was published. The allowlist is the read-only tools the case lists in `allowed_tools`, from `Read`, `Glob`, `Grep`, `NotebookRead`, `Skill`, `Agent`, `TodoWrite`, and the task tools `TaskCreate`, `TaskGet`, `TaskList`, `TaskUpdate`, and `TaskStop`, plus … plugin-evals see the edit
Confirmed since Anthropic's documentation has since written up --allow-tools, on Plugins reference. The optional `target` is a plugin directory, a single `prompt.md` or `case.yaml` file, an installed plugin as `name` or `name@marketplace`, or `name@skills-dir`, and defaults to the current directory. Put it before `--tag`, `--allow-tools`… plugins-reference see the edit
