# T-722: SubWorker cwd and logical path friction During delegation from the assigned repository Workdir, a child started with `cwd: crates/server-api` and readable policy paths under repository-root `docs/development`. Its Read calls using repository-relative logical paths could not read the required testing strategy; absolute paths were rejected as invalid logical paths too. The child correctly stopped without edits. The parent inspected the committed child session, stopped that idle child, and recreated it with repository-root cwd and explicit read-only repository scope plus write scope limited to server-api. Policy reads and implementation then succeeded. The current observable behavior appears to root child filesystem tools at the selected cwd, rather than making cwd only the command default as the spawn-tool description states. This makes repository-root logical paths surprising. Consider keeping the attachment root invariant and applying cwd only to command execution, or documenting/returning a distinct filesystem base explicitly. Do not encourage absolute paths, parent traversal, or broader write grants as a workaround. This report records a tool usability issue, not additional Ticket requirements.
