gw guard — Claude Code hook helper that vets inbound Bash tool calls.
Input format: a JSON object with at least tool_name and tool_input.
For Bash, tool_input.command is matched against a small risk pattern
list. If the command is risky AND the cwd looks unhealthy (missing or
not a directory), the helper exits non-zero with a stderr message,
causing Claude Code to refuse the tool call.
