  Hardstop - Pre-execution safety layer control. Use this skill when the user wants to

# Hardstop Control

**Purpose:** Control the Hardstop pre-execution safety layer that blocks dangerous shell commands.

When the user invokes ``/hs`` (with optional subcommands), run the appropriate Python command:

- ``/hs`` or ``/hs status``: ``python $PluginDest/commands/hs_cmd.py status``
- ``/hs on``: ``python $PluginDest/commands/hs_cmd.py on``
- ``/hs off``: ``python $PluginDest/commands/hs_cmd.py off``
- ``/hs skip``: ``python $PluginDest/commands/hs_cmd.py skip``
- ``/hs log``: ``python $PluginDest/commands/hs_cmd.py log``
