- **`workspace`**: path resolve under root; path substring denylist; command basename denylist; clearer deny messages.
- **`file`**: `read_file`, `write_file`, `listdir`, `tree`, `glob_paths`, `grep_files` (regex, skip VCS/binary), `edit_replace`, `edit_lineno` (1-based range), `copy_path` / `move_path` / `delete_path`.

- PTY: structured status (`alive`/`exit_code`/`data`); `read_pty(..., until=)`; session limit/idle TTL/output budget; close SIGTERM→SIGKILL.

- PTY: backend in `pty_backend.py`; structured status (`alive`/`exit_code`/`data`); `read_pty(..., until=)`; session limit/idle TTL/output budget; close terminate→kill.
- CLI limit hooks: interactive confirm to raise tool-loop rounds, PTY session cap, or PTY output budget.

- **`vcs`**: read-only VCS tools (`vcs_kind` / `vcs_status` / `vcs_diff` / `vcs_log` / `vcs_branch`) via `VcsBackend` protocol; **git** implemented; detectors are pluggable for other systems.
